Abstract Marin, V., Moreno, M., Vassallo, P., Vezzulli, L., and Fabiano, M. 2008. Development of a multistep indicator-based approach (MIBA) for the assessment of environmental quality of harbours. – ICES Journal of Marine Science, 65: 1436–1441. Environmental pollution in harbours can have detrimental effects on the port, its users, and the surrounding environment. Despite these risks, the Italian legal framework for marine environmental quality does not apply to harbours and marinas, so monitoring is not mandatory. With the aim of supporting environmentally sound management, we propose an indicator-based protocol to assess the environmental quality of harbours through the development of a flexible and site-specific multistep indicator-based approach (MIBA), which gives special consideration to local features. MIBA comprises three steps: (1) development of a simple tool for harbour-specific identification of vulnerable areas and for designing monitoring schemes; (2) selection of suitable environmental quality indicators of different levels of complexity and applicability to the typologies of risks involved; and (3) development of a user-friendly interpretation scheme based on categorical risk values and a visualization code. The approach has been tested in two case studies in marinas located in the Ligurian Sea (Italy).

Abstract Non-Indigenous Species (NIS) are a threat to native biodiversity and ecosystem services. The European seas are known to be the recipient of several hundreds of NIS due two main origins: shipping and aquaculture. They are the focus of Descriptor 2 of good environmental status in the Marine Strategy Framework Directive. 153 NNS had been recorded along the Normandy coast in 2018. Marinas are priority sites for monitoring, being ‘hotspots’ for the NIS occurrence. The aim of the ENBIMANOR project was to study and compare the composition and the hard-bottom macrofauna including the NIS prevalence in marinas along the Normandy coast (from Granville to Dieppe-Le Tréport) focusing primarily on mobile and benthic invertebrates. A total of 19 marinas were surveyed during two years (2018-2020). At each harbour, nine settlements panels (acting as artificial reef) were immerged at a depth of 1.50 m. Every quarter, at each site, a settlement panel was replaced and the species colonising the panel were identified. The analysis revealed higher taxonomic richness in marinas open to the sea or with high salinity than in closed marinas or with low salinity. Results highlighted that each marina has its own species composition. This survey identified more than one hundred taxa, including known NIS species such as the amphipod Monocorophium acherusicum and M. sextonae, the ascidians Perophora japonica and Stylea clava, and detect four new NIS for the Normandy waters (Aoroides longimerus, A. curvipes, Paranthura japonica and Ianiropsis serricaudis). Our study shows the need to continue the census of NIS and to evaluate their impacts on the artificial hard-bottom structures in marine coastal ecosystem on two major zones: the intertidal zone and the marina/harbours waters.

Flushing or residence times are typically used as a first step in assessing water quality in marinas, harbours and coastal basins. Recent publications have offered guidance in relation to optimal marina basin and entrance geometries to help achieve rapid renewal. However, these guidelines have been developed for the particular case where water exchange is strongly tide-driven and are not widely applicable, particularly in micro-tidal regions. Where water renewal rates are dominated by shear-driven circulation and lateral transfer of momentum at the interface between the marina and the adjacent water body (i.e. a mixing layer), there is a strong analogy to groyne fields and other cases involving flows containing quasi-stagnant peripheral areas (dead zones). A series of numerical hydrodynamic models, developed in the TELEMAC system, were used to investigate the potential for the dead zone model of water exchange to provide a better means to guide optimization of basin and entrance geometry under such conditions. Real-world marina case studies were used to identify any constraints affecting the practical implementation of such an approach. The numerical model results demonstrate particular conditions under which the dead zone model of water exchange can be used effectively to optimize marina basin and entrance geometry.

Spatio-temporal changes in genetic structure among populations provide crucial information on the dynamics of secondary spread for introduced marine species. However, temporal components have rarely been taken into consideration when studying the population genetics of non-indigenous species. This study analysed the genetic structure ofStyela plicata,a solitary ascidian introduced in harbours and marinas of tropical and temperate waters, across spatial and temporal scales. A fragment of the mitochondrial gene Cytochrome Oxidase subunit I (COI) was sequenced from 395 individuals collected at 9 harbours along the NW Mediterranean coast and adjacent Atlantic waters (> 1,200 km range) at two time points 5 years apart (2009 and 2014). The levels of gene diversity were relatively low for all 9 locations in both years. Analyses of genetic differentiation and distribution of molecular variance revealed strong genetic structure, with significant differences among many populations, but no significant differences among years. A weak and marginally significant correlation between geographic distance and gene differentiation was found. Our results revealed spatial structure and temporal genetic homogeneity inS. plicata, suggesting a limited role of recurrent, vessel-mediated transport of organisms among small to medium-size harbours. Our study area is representative of many highly urbanized coasts with dense harbours. In these environments, the episodic chance arrival of colonisers appears to determine the genetic structure of harbour populations and the genetic composition of these early colonising individuals persists in the respective harbours, at least over moderate time frames (five years) that encompass ca. 20 generations ofS. plicata.

This paper describes an experimental and a numerical study of the wave-induced response of a moored vessel near a reflecting wall, for the purpose of incorporating wave reflection effects into wave agitation criteria for small craft harbours. The motions of a model vessel have been measured for a range of wave heights, wave periods, wave directions, mooring conditions, and vessel locations, and with both regular and irregular waves. These have been compared with the results of a numerical model based on linear diffraction theory. An expression is developed to relate vessel motions near a partially reflecting wall to motions in unreflected waves. This has been found to agree well with the experimental results, and is used to recommend an extension to existing wave agitation criteria for small craft harbours so as to take account of the presence of reflecting walls. Key words: coastal engineering, harbours, hydrodynamics, marinas, wave agitation, waves.

Abstract A survey of water and sediment from 152 harbours, marinas and shipping channels across Canada was conducted in 1999 to determine the extent of contamination by tributyltin (TBT) prior to the total ban on its antifouling uses being phased in over the period 2003 to 2008, and to assess the effectiveness of the 1989 regulation of antifouling uses of TBT under the Canadian Pest Control Products Act. TBT was found in sediments in this survey much more frequently than in water. The main conclusion was that by 1999 the regulation had been generally effective in reducing TBT contamination in water, but not sediment, in small-craft marinas and harbours. TBT continued to be found in some freshwater and seawater locations frequented by larger vessels, that could have been legally painted at the time with TBT antifouling paints, at concentrations that could cause chronic toxicity to aquatic organisms. TBT was also found in many marine sediments, and some freshwater sediments, at concentrations that could cause chronic toxicity to sensitive benthic organisms. In addition, TBT concentrations in many marine sediments could cause acute toxicity to sensitive benthic organisms. Because of the long persistence of TBT in sediments, it may pose a hazard to benthic organisms in some locations in Canada for many years after the total ban on antifouling uses of TBT.

The development of yacht harbours in Wrocław is a significant element of European transport policy, linked to maintaining mobility with minimal environmental impact. The increasing popularity of recreational navigation and the development of a port infrastructure reflect societal awareness and new expectations related to leisure. The Oder, the second longest river in Poland, serves as a navigable route, and the Wrocław Water Node constitutes a unique 45 km-long system. The research aimed to present Wrocław's spatial policy regarding yacht ports and marinas. The analysis of the major ports highlights the diversity of their condition while maintaining their port functions within local plans. Planned investments include new moorings, marinas, parking spaces, restaurants, green areas, and tourist infrastructure. These ports were also analysed based on Wrocław's ownership structure. The study employed various methods, including literature analysis, primary documents, legal acts, cartographic materials, field research, and in-depth interviews.

Marinas are semi-enclosed environments characterised by reduced hydrodynamic energy, high sedimentation rates, and reduced oxygen levels. The ongoing development of activities and infrastructure construction are leading to deterioration in the quality of coastal aquatic environments, creating environmental risks. Trace metal elements (TMEs) and organotins are significant contaminants, prompting this study to evaluate the added value of spatiotemporal monitoring compared to one-time sediment assessments. Two Mediterranean harbours, Port Camargue (PC) and Port Carnon (C), differing in morphology and size, were monitored for a year with regular water sampling, focusing on TMEs and organotins. Sediment contamination, notably in the technical zone, revealed concentrations of Cu (309 and 1210 mg kg−1 for C and PC, respectively), Zn (242 and 425 mg kg−1 for C and PC, respectively), and tributyltin (TBT) (198 and 4678 µg (Sn) kg−1 for C and PC, respectively) surpassing the effect range medium (ERM), while other marina stations generally stayed below this threshold. Spatiotemporal water monitoring highlighted concentrations above environmental quality standards (EQS) at all stations of the larger marina. This exceedance was systematic for Cu and Zn in all samples, ranging respectively between 2.54 and 37.56 µg (Sn) L−1 and 0.63 and 33.48 µg (Sn) L−1. A notable temporal dynamic for TBT and Cu was also observed. Conversely, the open marina, connected to the open sea, rarely exhibited concentrations above EQS in water, despite sediment concentrations occasionally exceeding ERM values. This underscores that risk assessment in these ecosystems cannot rely solely on sediment characterisation.

An existing analytical model to predict wave attenuation in a straight vertically walled channel with one or both walls lined with rubble is tested and modified. Placing rubble at side slopes of 1.5 or 2 to 1 along vertical entrance channel walls is a technique used more and more to correct wave agitation problems in harbours. Tests were conducted in a laboratory flume with monochromatic waves and four different sizes of stone from 7.7 mm gravel to 90 mm gabion stone. The attenuation coefficient is found to vary with the ratio of water depth to period squared, d/gT2, with the relative channel width, w/d, and with the side slope of the rubble, m. Preliminary design curves are provided which allow a desk assessment of this technique to be made for a given harbour. The scale effects on wave attenuation due to stone size or shape appear to be negligible. Reynolds number scale effects are also shown to be unimportant over the range tested. Key words: coastal engineering, waves, marinas, wave agitation, wave attenuation.

Le développement côtier introduit des habitats artificiels qui impactent la biodiversité et le fonctionnement des écosystèmes. Les solutions d'ingénierie écologique, comme les habitats artificiels à poissons (HAP), peuvent réhabiliter des zones très modifiées, comme les ports, en offrant un abri aux poissons. Les HAP peuvent aussi fournir un substrat aux invertébrés et aux macroalgues, améliorant le fonctionnement de l'écosystème. Leurs effets pourraient aller au-delà des ports et modifier les échanges trophiques avec les habitats adjacents. Cette thèse étudie la biodiversité des invertébrés associés aux HAP et explore les échanges de biomasse entre les ports et les herbiers de Posidonia oceanica adjacents le long de la côte méditerranéenne française.Les objectifs sont : (1) évaluer comment la diversité et la composition des invertébrés benthiques varient avec le temps d'immersion des HAP, (2) comprendre comment les types d'HAP et le contexte environnemental modifient les assemblages benthiques, et (3) explorer les échanges de matière organique entre les ports et les herbiers adjacents. J'ai étudié les HAP Biohut® (ECOCEAN), composés d'une cage métallique remplie de coquilles d'huîtres, attachés aux quais ou sous les pontons dans les ports.Au chapitre 1, j'ai examiné le rôle du temps d'immersion des HAP sur la diversité et la composition des assemblages d'invertébrés dans 3 ports commerciaux. Des variations dans la composition des invertébrés ont été observées entre 6 et 18 mois d'immersion, avec une augmentation de l'abondance, de la richesse et de l'équitabilité au fil du temps. Au chapitre 2, j'ai étudié les variations géographiques et intra-portuaires de la composition et de la diversité des invertébrés. L'étude a révélé des différences dans la composition des taxons entre 2 régions caractérisées par des apports en nutriments différents et des corrélations entre la composition des assemblages et la chlorophylle-a, indicateur de la concentration en nutriments. Les assemblages d'invertébrés variaient aussi selon les zones où les HAP étaient installés, probablement à cause de différences d'accès à la lumière. Au chapitre 3, j'ai étudié la connectivité trophique entre les herbiers de P. oceanica et les ports adjacents sur 4 sites : 2 avec des ports équipés en HAP et 2 non équipés. Dans les sites non équipés, les valeurs δ15N de la matière organique particulaire à l'intérieur du port étaient les plus élevées, suggérant un enrichissement en nutriments d'origine humaine. Ces valeurs diminuaient dans les herbiers selon la distance, indiquant un effet de ces nutriments sur l'herbier proche de l'entrée du port. Les poissons (Diplodus spp.) pouvaient utiliser des ressources venant à la fois de l'herbier et du port de manière similaire sur les 4 sites. Les niches trophiques des poissons capturés dans le port équipé étaient légèrement plus grandes que celles des ports non équipés et se chevauchaient moins avec celles des poissons capturés à l'extérieur. Leurs fèces faisaient également partie de la matière organique sédimentaires des herbiers. Au chapitre 4, j'ai présenté des projets développés avec d'autres scientifiques sur la diversité fonctionnelle des espèces et les relations trophiques dans les HAP, des mesures bioacoustiques sur les AFH et une comparaison de la biodiversité entre les ports et les réserves marines à l'aide d'ADN environnemental.Mon travail a révélé des aspects susceptibles d'améliorer l'utilisation des HAP. La durée d'immersion, les conditions environnementales et les emplacements dans les ports doivent faire l'objet d'une attention particulière. Bien que je n'aie pas trouvé de différences claires dans les échanges entre habitats liés aux HAP, ces derniers semblent jouer un rôle en réduisant l'enrichissement en nutriments. L'importance des poissons dans les échanges entre habitats et le fait que les HAP favorisent leur survie suggèrent que ces HAP pourraient contribuer indirectement à la connectivité trophique
Coastal development modifies shorelines by introducing man-made habitats, which significantly impact coastal biodiversity and ecosystem functioning. Ecological engineering solutions, such as artificial fish habitats (AFH), can help rehabilitate extremely modified areas, including ports, by offering shelter for fish. As a side effect, AFH provide a substrate to benthic invertebrates and macroalgae, that could improve ecosystem functioning. The effects of AFH may also extend beyond ports and modify trophic exchange with adjacent habitats via fish feeding hydrodynamics. This thesis investigates the patterns of distribution of invertebrate biodiversity associated with AFH and explores the exchange of biomass between marinas and adjacent Posidonia oceanica meadows along the French Mediterranean coast where these habitats are often adjacent.The objectives are: (1) evaluating how taxonomic diversity and composition of benthic invertebrates vary with AFH immersion time, (2) understanding how AFH types and environmental context modify benthic assemblages, and (3) exploring the exchanges of organic matter between marinas and adjacent meadows. I focused on Biohut® AFH (ECOCEAN), made of a metal cage filled with oyster shells, attached to docks or under pontoons in harbours and marinas.In chapter 1, I examined the role of immersion time in determining the diversity and composition of invertebrate assemblages colonising AFH in 3 commercial harbours. The findings indicated significant variations in invertebrate composition from 6 to 18 months, with increased abundance, taxonomic richness, and evenness over time. In chapter 2, I focused on the geographical and within-port variability in taxonomic composition and diversity of invertebrates dwelling in AFH. The study revealed differences in taxa composition between 2 large regions, characterised by different nutrient loads and correlations between assemblage composition and chlorophyll-a, a proxy for nutrient concentration. The number of taxa was the highest in the nutrient-enriched region. Additionally, invertebrate assemblages varied according to port habitats where the AFH were placed, possibly due to differences in light availability. In chapter 3, I investigated trophic connectivity between P. oceanica meadows and adjacent marinas at 4 sites where both habitats are present. Two marinas were equipped with AFH and the remaining 2 were not. At the unequipped sites, the δ15N values of the particulate organic matter within the marina were the highest indicating human-derived nutrient enrichment. The values decreased within the meadow, gradually according to the distance. This suggests a spill of nutrients over the portion of the meadow adjacent to the inlet. Fish relied on resources from both the seagrass meadow and the marina, similarly among the 4 sites, however, the trophic niches of fishes (Diplodus spp.) captured within the equipped marina were slightly larger than those within unequipped ones and overlapped less with the trophic niches of the fish captured outside. Fish faeces were also part of the organic matter sedimenting within meadows. In chapter 4, I reported initiatives developed with other scientists. They include species functional diversity and trophic relations within AFH, acoustic signatures of organisms dwelling in AFH and biodiversity comparison between ports and marine reserves using environmental DNA.My work has highlighted several aspects that could improve the effectiveness of AFH as ecological engineering solutions. Immersion time, local environmental conditions, and specific locations within ports need particular attention. Although I did not find clear differences in cross-habitat exchange related to AFH, they seemed to play a role in reducing nutrient enrichment. Moreover, since fish play an important role in cross-habitat exchanges and find refuge within AFH, this ecological engineering solution could indirectly contribute to change trophic connectivity

ENGLISH ABSTRACT: For the safekeeping or harbouring of small craft, whether for leisure or commercial use, a tranquil basin is the principle requirement in designing a functional harbour facility. Waves transmitted through the perimeter structures of a marina result in agitation of the basin and thereby a reduction in tranquillity. Similarly, waves reflected off the perimeter structures that line entrance channels could result in difficulty when manoeuvring through the entrance channel water areas. An alternative to the conventional breakwater becomes a necessity when the conventional mass-filled or caisson breakwaters are not feasible in technical or financial terms. One of the alternative options could be to consider a piled row breakwater. In broad terms, this consists of closely spaced piles that attenuate wave energy whilst not forming an impermeable barrier, allowing for currents and sediment to pass through. When comparing the different options for creating a piled row breakwater the quantity of material used to achieve a desired level of wave dissipation could be the most important aspect in considering possible alternatives, as this would relate directly to construction costs and time when considering implementation. A literature review revealed multiple references to theories that predicted the transmitted and reflected waves for various breakwater porosities and wave conditions. However, there is limited coverage in literature enabling prospective designers. For example, literature describing the applicable ranges of shape configurations that one should start off with when developing concepts is not readily available. This thesis study used physical modelling to compare the wave transmission properties of breakwaters comprised of three different piled element shapes, namely round, square and diagonal square piles. The pile element shapes are compared for varying porosity values over a range of input wave parameters. A comparison of the transmission incurred by these configurations with previous work is presented and it was found that the physical model experiment closely simulated the predicted values. The tests were scaled from actual conditions in possible marina locations and therefore the performance criteria measured could be applied in reverse to potential site locations. From analysis of the physical model results, it was clear that the highest energy loss was found, in general, to occur with low porosities (below 10%), as could be expected. For a fixed screen configuration in terms of pile element shape and porosity, the performance is heavily dependent on wave steepness, the steeper waves incurring a lower transmission coefficient than the less steep waves. For a given porosity, circular piles performed the best (transmit the least) followed by square piles and then diagonal square. When comparing the material used, diagonal square piles yielded better performing breakwaters due to the expanded cross section gained in elevation. The work has provided useful insight into the performance of piled row breakwaters in restricting transmission of wave energy. Design guidance has been provided when considering the parameters for deriving conceptual layouts for piled row breakwater structures. Recommendations were put forward for further work in this field, including potential study areas, data gathering, and study methods, as well as more applied uses of piles, for example in combination with other elements in a marina.
AFRIKAANSE OPSOMMING: die veilige bewaring van klein vaartuie, hetsy vir ontspanning of kommersiële gebruik, is die hoofvereiste in die ontwerp van 'n funksionele hawe fasiliteit dat die beskermde hawegebied ‘n rustende water oppervlak sal moet handhaaf. Golwe wat oorgedra word deur die omtrek golfbrekers van ‘n hawe deur middel van transmissie veroorsaak oppervlak versteurings in die hawe bak en dus ook ongewensde versteurings in die vasmeer kondisies. Op ‘n soortgelyke wyse, veroorsaak golwe wat gereflekteer word vanaf die toegangs kanaal golfbrekers problematiese kondisies vir die navigeer van bote deur die kanaal. Die behoefte aan 'n golfbreker alternatief vir die konvensionele oplossing word genoodsaak wanneer die konvensionele stortrots of caisson golfbrekers nie haalbaar is nie as gevolg van tegniese of finansiële aspekte (Park et al. 2000). Een van die opsies wat oorweeg kan word as 'n alternatief is ‘n heipaal-ry tipe breekwater. In breë terme, bestaan dit uit naby gespasieërde heipale om golf energie te breek, sonder om ‘n ondeurdringbare versperring te vorm. Wanneer die verskillende opsies vir die skep van 'n heipaal-ry tipe breekwater vergelyk word, kan die hoeveelheid konstruksie materiaal benodig per opsie die belangrikste vergelykende parameter word. Die rede hiervoor is die direkte verwantskap aan konstruksie kostes sowel as tyd aspekte wat gepaardgaan met die konstruksie materiaal hoeveelhede. Vanuit die literatuurstudie is verskeie verwysings geïdentifiseer waarin vorige teorieë oor oordrag en refleksie van golwe evalueer word vir wisselende porositeit waardes en intree golf waardes. Daar is egter 'n beperkte dekking in die literatuur wat ontwerps-riglyne betref. Byvoorbeeld, die toepaslike omvang van die vorm konfigurasies wat oorweeg moet word wanneer konsep ontwerp gedoen word, is nie geredelik beskikbaar nie. Hierdie tesis vergelyk, deur middel van fisiese skaal model toetse, drie heipaal-ry element vorms, naamlik ronde, vierkantige en diagonal geroteerde vierkante vir verskillende porositeit waardes oor 'n verskeidenheid van golf inset parameters. 'n Vergelyking is getref tussen die toetsdata en vorige werk en daar is bevind dat die fisiese model eksperiment die voorspelde waades uit die literatuur redelik akkuraat kon naboots. Die toets kondisies is geskaal vanaf werklike moontlike marina terreine en dus kon die toets resultate toegepas word in die ontwerp van potensiële terreine. Vanuit die data-analise, is waargeneem dat die hoogste energie verliese oor die algemeen plaasvind by laer porosititeit waardes (onder 10%) soos wat verwag kon word. Vir 'n gegewe golfbreker opset, in terme van die heipaal element vorm en porositeit, is die verrigting hoogs afhanklik van die golf steilheid, met hoër verrigting by steiler golwe. Vir 'n gegewe porositeit, sal ronde heipaal elemente die beste verrigting gee, gevolg deur vierkante heipale en laastens diagonal geroteerde vierkante. Vir soortgelyke hoeveelheid heipale, sal diagonal geroteerde vierkante beter verrigting lewer moontlik as gevolg van die verlengde deursnit dimensie in vooraansig. Hierdie navorsing het goeie insig verskaf oor golfdeurlaatbaarheid en weerkaatsing van heipaalry breekwaters. Ontwerp riglyne word ook verskaf wat betref die parameters wat gebruik kan word vir die konsep ontwikkelings fase vir heipaal-ry breekwaters. Aanbevelings word gemaak vir verdere navorsingswerk in hierdie veld, insluitend moontlike studie-areas, data insameling, studie metodes, sowel as vir meer toegepasde situasies, byvoorbeeld waar die heipaal elemente in kombinasie met ander marina komponente ontwerp moet word.

Turkey, with its climate, protected bays, cultural and environmental resources is an ideal place for yacht tourism. Subsequently, yacht tourism is increasing consistently. Yacht tourism can cause unmitigated development and environmental concerns when aiming to achieve tourist satisfaction. As the demand for yacht tourism intensifies, sustainable development strategies are needed to maximize natural, cultural and economic benefits. Integration of forecasts to the strategic planning is necessary for sustainable and use of the coastal resources. In this study two different quantitative forecasting techniques - Exponential smoothing and Auto-Regressive Integrated Moving Average (ARIMA) methods were used to estimate the demand for yacht berthing capacity demand till 2030 in Turkey. Based on environmental, socio-economic and geographic data and the opinions gathered from stakeholders such as marina operators, local communities and government officials an allocation model was developed for the successful allocation of the predicted demand seeking social and economical growth while preserving the coastal environment. AHP was used to identify and evaluate the development, social and environmental and geographic priorities. Aiming a dynamic plan which is responsive to both national and international developments in yacht tourism, potential investment areas were determined for the investments required to accommodate the future demand. This study provides a multi dimensioned point of view to planning problem and highlights the need for sustainable and dynamic planning at delicate and high demand areas such as coasts.

Annotation:

Seagrass ecosystems are some of the most productive in the world and provide a variety of ecosystem services but are facing global decline chiefly due to anthropogenic disturbance. Mechanical disturbances to seagrass meadows from anchoring, propeller scars, and mooring scars result in losses or damage to both shoots and the underlying rhizome. I conducted a literature synthesis on the extent of, recovery from, and ecological impacts of these mechanical disturbances to seagrass meadows. The literature suggests that anchoring damage tends to be worst in deeper water where larger vessels anchor and can cause large (>100m2) loss per anchoring and recovery may take decades to over a century. Propeller damage is of largest concern in shallow (<2m) areas experiencing heavy boat traffic because propeller damage can only occur where the propeller can come close to the seagrass. Mooring damage is highly variable depending on the type of mooring used (<10m2 to >1000m2 scoured per mooring). Seagrass patches experiencing these mechanical disturbances have, in some studies, been found to have lower seagrass percent cover and shoot density than reference areas. This indicates scars can have ‘halos’ of impacted seagrass meadow. Some seagrass systems cannot recover within a century (e.g. Posidonia oceanica meadows at the extent of their depth tolerance) while others recover annually from some disturbances (e.g., anchor scars <1m2). Systems face altered species composition when scars are preferentially recolonized by certain species and patterns of recovery are affected by altered biogeochemical conditions following disturbances. Additionally, mooring, anchoring, and propeller scarring frequently alter meadow density, cover, patch size, patch shape, patch isolation, edge area, and ratios of edge to interior meadow leading to changes in faunal community structure. Correlations between these disturbances and faunal abundances, densities, and richness in seagrass ecosystems are complex, vary temporally (sometimes on the scale of days), and may result in species showing positive, negative, or no responses to a wide range of disturbance regimes.

To explore the connections between mooring scarring, the surrounding seagrass meadow condition and epifaunal community, in the second part of this thesis I measured 30 mooring scars to determine average scar size. To explore any potential ‘halo’ effect around mooring scars for seagrass or epifauna and to seek any difference in epifaunal community between mooring and reference sites I also sampled paired sites at eight locations in Nantucket Harbor, Massachusetts three times each in the summer of 2015. Each location consisted of a meadow site actively experiencing mooring scarring and a reference site without moorings. My conservative sampling methods of the 30 sampled mooring scars found scars to average 21.1m2. Across my paired sites, seagrass was found to have lower cover and lower canopy height in mooring versus reference sites. Seagrass cover and canopy height were lower in the first few meters (typically 2-3m) surrounding each scar in comparison to paired reference quadrats indicating a ‘halo’ effect of each scar. I did not detect a difference in epifaunal community composition or density per blade between mooring and reference sites; however, the relatively constant per blade concentration of epifauna combined with the differences in seagrass biomass between the mooring versus reference sites indicate an overall increase in the total amount of epifauna in areas with less disturbance. Epifaunal community composition was different and between locations and sampling dates indicating these factors are more important than proximity to mooring scarring in determining epifaunal abundance and richness. When considering scar area and the ‘halo’ of each scar I estimate that at least 32ha (2%) of Nantucket Harbor was impacted by mooring scarring. Given that the estimates of seagrass do not include areas previously denuded of this plant and that my measurements were conservative, likely a larger portion of this harbor’s potential seagrass habitat is impacted. Combined with the findings of loss due to these direct boat-related physical disturbances of seagrass meadows worldwide across regions, this halo effect is likely to also be found for moorings globally. I encourage management of the issue by employing and fine-tuning mooring methods (such as deploying moorings with anchor connections that do not drag on the sea floor) to minimize these unintentional but strong effects of mooring on the recipient habitat.

Os aspectos ambientais relacionados às atividades cotidianas de marinas de águas interiores, de terminais hidroviários de passageiros, de embarcações de lazer e de turismo e de outras instalações de apoio, como os estaleiros fluviais, indicam a necessidade da adoção de modelos sustentáveis de gerenciamento destas organizações, pois suas atividades ocorrem diretamente nos corpos d\'água e nas margens de rios e reservatórios, áreas estratégicas para o equilíbrio dos ecossistemas aquáticos e protegidas por uma legislação ambiental rigorosa. Este trabalho sugere alternativas tecnológicas e propõe a implementação de um programa de gestão de resíduos e efluentes, visando adequar a infra-estrutura e a operação de marinas, de terminais de passageiros e de embarcações de turismo, lazer e recreio, à série de normas ISO 14000 e a legislação ambiental, em relação à destinação dos resíduos sólidos, dos resíduos oleosos e dos efluentes sanitários gerados. As propostas foram fundamentadas em dados provenientes de uma avaliação sobre a situação atual das instalações receptoras, dos equipamentos e da gestão de resíduos e efluentes, realizada em uma marina e em uma empresa de navegação de turismo que operam no reservatório de Bariri, na Hidrovia Tietê-Paraná. Os resultados deste trabalho demonstram a importância da implementação de programas de treinamento e de controle dos resíduos e dos efluentes gerados nas atividades em terra e a bordo. Esses programas baseiam-se na redução da geração dos resíduos, na segregação, na reutilização e na reciclagem dos materiais, assim como na educação ambiental e no tratamento e destinação final adequada dos resíduos e efluentes, possibilitando, desta forma, a prevenção, o controle e o combate da poluição dos recursos hídricos, além de proporcionar o aumento da atratividade do empreendimento e da segurança e satisfação de usuários e de funcionários.
The environmental aspects related to the daily operations in small craft inland harbors, in passenger waterway terminals, in leisure and tour vessels, in addition to other supporting facilities such as fluvial shipyards, indicate the need for adoption of sustainable models of management of such organizations, due to the fact that their activities are directly related to water bodies and to river banks and reservoirs, which are strategic areas for the aquatic ecosystems balance and protected by a strict environmental legislation. This study focus on technological options and proposes the implementation of a management program of waste and sewage in order to adapt the facilities and the operation of the marinas, passenger terminals and recreational boating to the ISO 14000 serial rules and to the environmental legislation in relation to the destination of solid wastes, oily residues and sewage effluents. The proposals were based on data from an investigation about the current situation of the facilities, the equipment, and the waste and sewage management, carried on both a marina and a tour navigation company which operate in the Bariri reservoir in the Tietê-Paraná Waterway. The results of this study demonstrate the importance of the implementation of programs for training and controlling the waste and sewage produced in shore and off-shore activities. These programs are based on the reduction of the production of waste, on the segregation, on the reutilization and the recycling of the materials, as well as on environmental education and on the treatment and final destination of waste and sewage. This way, they may prevent, control and act against water resources pollution besides making business more attractive and the places safer and more appealing for users and workers.

Annotation:
Computer models are nowadays routinely used in harbor engineering applications. Models based on the two-dimensional elliptic mild-slope equation can simultaneously simulate refraction, diffraction, reflection, and dissipation in completely arbitrary coastal domains. However, floating structures such as floating breakwaters and docks are often encountered in the modeling domain. This makes the problem locally 3- dimensional. Hence it is problematic to incorporate a floating structure into the 2-d model. Tsay and Liu (1983) proposed a highly simplified but approximate approach to handle this problem practically. The validity of their approach is examined in detail and it is found that the actual solutions deviate considerably from the theoretical solutions, although their approximation provides results with the correct trend. Therefore, correction factors have been developed and may be used to produce more reliable results using the framework of Tsay and Liu (1983). The resulting method is applied to Douglas harbor in Alaska. The result shows that docks in the harbor distort the wave field considerably and create a reflective pattern that can affect navigation safety in some areas. Also plots are developed for the transmission coefficients for waves propagating past rectangular and cylindrical floating objects of infinite extent for a wide range of conditions encountered in practice.

Annotation:
Harbors are extreme examples of coastal urbanization. Artificial substrata in the Ravenna harbour are almost completely dominated by mussel beds. Mussel clumps provide substrata for small mobile fauna (meiofauna). The aim of the thesis is to study the meiofauna associated to the mussels attached to the harbour structures. Moreover, the thesis provides the basis for the construction of a local meiofaunal genetic database, with the final goal of time and cost reduction on meiofaunal assessment through a metabarcoding approach. Mussel beds and associated meiofauna were sampled in two locations of the port (North vs. South) in two types of artificial substrata (rock boulders vs. concrete seawalls) at two different times. Taxonomic assessment of the meiofauna was carried out. Mussel bed complexity was evaluated by means of different measures (e.g. weight, volume, length of valve). The main results are: 1) meiofauna assemblages are very different in the two substrata, but these differences were influenced by locations and by the sampling periods. The number of taxa and diversity index on the rock boulders, the more complex primary substratum, resulted higher than those on the seawalls. 2) Variables analysed altogether showed differences between substrata, locations and times. A weak correlation was found between the mussel bed descriptors and the associated meiofauna assemblages. The number of structural mussels and the mean size lengths resulted responsible for the relationship. These results suggest that other measures of mussel complexity are needed, and that meiofauna assemblages vary depending on different substrata and to abiotic conditions associated to the locations (e.g. marine currents, exposition-to-sun). The genetic research identified a lack of sequences of species from the Adriatic Sea, especially for the “permanent” meiofauna. Alignment of the available sequences identified in the V7 and V8 regions of the SSU_18S a good target for meiofaunal barcoding.

Annotation:
Coastal urbanization is resulting in shorelines being increasingly built-over and protected by artificial structures which are generally colonized by species poor assemblages dominated by opportunistic organisms. “Eco” approaches integrating ecological research into the design of these structures, such as enhancing substrate complexity and seeding of surfaces with target organisms, provide the chance to improve the structure and function of target-designed novel ecosystems. I tested the effects of two design techniques, specifically tiles mimicking increasing substrate complexity and seeding of habitat forming oysters, on the development of benthic intertidal assemblages at two jetty sites of Ravenna’s port. I used orthogonal combinations of different complexity tiles (flat, 2.5 cm high ridges tiles and 5 cm high ridges) and two seeding conditions (unseeded and seeded with oyster recruits), and measured the developing assemblages over the first 6 months. I also analysed the effect of substrate complexity on seeded oyster survivorship and growth. A great difference between the assemblages at the two sites was detected due mostly to higher presence of algae at the southern site and bare substrate at the northern site. Lower abundance of the opportunistic algae Ulva spp. and Cladophora sp. were registered on more complex tiles. The same algae were more abundant on unseeded tiles. The seeded oysters reduced the presence of opportunistic species by both space pre-emption and by creating biogenic microhabitats. No effects of substrate complexity was observed on oyster survivorship and growth. These results suggest that both increasing substrate complexity and seeding could help reducing the presence of opportunistic species on port structure in the short term. Longer-term observations will be needed to explore the efficacy of these interventions over longer times and their practical applications on port seawalls and other types of artificial structures.

Der volle Inhalt der Quelle
Annotation:
The increase of human population and their pressures in coastal areas is causing an exponential sprawl of artificial structures in marine areas, leading to the loss of natural habitats. Artificial structures are characterised by low species richness and a prevalence of non-native species compared to natural rocky reefs. Commercial and tourist ports are examples of artificial habitats. Little is known about the distribution and dynamic of the species inhabiting ports, and the factors leading to a prevalence of non-native species in these habitats are still not fully understood. Here, the distribution and abundances of two native (Mytilus galloprovincialis, Ostrea edulis) and two non-native (Xenostrobus securis, Crassostrea gigas) bivalve species that grow on the artificial seawalls of the canal-port of Ravenna were assessed to: 1) explore their distribution in different areas of the harbour, and 2) identify whether the observed patterns were related to variations in environmental parameters or to variable supply of larvae reaching different areas of the port and settling on the artificial seawalls. DNA extraction and amplification protocols were developed to barcode the bivalves settlers due to the impossibility to identify them microscopically. Results showed an increase of non-native species as the canal-port goes inland. Temperature, oxygen and nitrate seawater concentration explained most of the variation in species abundance among sites. The non-native mussel X. securis was associated to higher sea surface temperatures compared to the native M. galloprovincialis. Settler abundances were clearly correlated to the spawning window of the species, but not to adult abundances on the seawalls, suggesting a prevailing role of post-settlement processes. Future work should explore the potential role of other environmental variables, extend the duration of the observations, and use a metagenomics approach to characterise propagule pressure dynamics in the water column.

Marine space has a variety of appealing elements such as in use as resorts, for leisure, marine sports, physical distribution and the function involving the flow of people. However, ports and harbors that have lost their physical distribution functions and are steadily declining are on the increase. The Ministry of Land, Infrastructure and Transport is attempting to undertake regeneration of such ports and harbors that have lost their vitality from the middle of the 20th century. To date, regeneration plans for ports and harbors have been under the initiative of government administration but today, plans for the regeneration of ports and harbors and measures for revitalizing port towns are being reviewed in various ways including the creative development of communities through participation of the local citizenry and the convening of workshops by NPOs. As a part of this, the Chiba Port and Harbor Office in which the national government invests has begun a trial attempt to launch new projects for the invigoration of port towns through the formation of a program under which plans for the regeneration of ports and harbors and the invigoration of port towns will be undertaken through the collaboration of universities and local administrative governments. As a forerunner to such a model project, a program to form a regeneration plan for Kisarazu Port through the collaboration of Kisarazu and the Department of Oceanic Architecture & Engineering of Nihon University for senior 4th year students with the national government’s Chiba Port and Harbor Office as the moderator has been undertaken. At Nihon University, in the curriculum of Oceanic Architecture, A Planning Studio, 7 teachers and 58 students participated and 14 classes with three hours each week were conducted. This paper introduces the background to this and reports on the status of local contribution by the university.

Annotation:
Due to the mobility and low costs, floating breakwaters have been frequently considered as alternatives for protecting marinas and harbors from wave attacks. Main advantages of using floating breakwaters include (i) the exchange of water between a harbor and ocean, and (ii) an adjustable elevation varying with tidal levels. When floating breakwaters are used in shallow water environments (during low tides), the presence of seabed may affect the dynamics of the floating breakwaters. In the present study, a series of experiments were carried out in a wave flume of 1.5m wide and 45m long to study the effects of water depth on the performance of a moored floating breakwater. An inertial measurement unit mounted on the breakwater measures the motion responses. The wave reflection and transmission coefficients and the responses of the breakwater to regular waves are presented for four difference water depths.

The U.S. Army Corps of Engineers (USACE) is responsible for maintaining the nation’s infrastructure to include ports and harbors through dredging of Federal navigation channels as well as shoreline stabilization. Shoreline stabilization through beach nourishment activities can provide opportunities for reductions in storm surge, flood control, and provide opportunities for residential growth, recreational activities, and coastal habitat restoration (Guilfoyle et al. 2019). Beach nourishment is an effective method for protection and enhancement of coastal development projects but may have detrimental impacts on marine life (e.g., nesting sea turtles and shorebirds). The objective of this Technical Report is to examine all elements of the beach nourishment process to include, active beach construction, entrainment of marine turtles in hopper dredges, beach protection and hard structures, beach profile features, compaction and shear resistance, artificial lighting, marine turtle nest relocation, and nesting habitat factors. Recommendations for mitigating and minimizing these impacts are provided.
