Abstract:

The majority of marine debris is found in shallow waters; however, submerged debris accumulated at the sea bottom is affected by this kind of pollution. To mitigate the harmful effect of marine debris, we have to recognize its characteristics. However, it is hard to estimate the quantity of submerged marine debris because the monitoring of submerged marine debris requires greater cost and time compared to the monitoring of beach or coastal debris. In this study, we used the data for submerged marine debris surveyed in the sea near the Korean Peninsula from 2017 to 2020 and the data of fishing vessels passing through the areas from 2018 to 2020. In addition, the correlation of major factors affecting the amount of submerged marine debris was analyzed based on the fishing vessel data and the removal project data for submerged marine debris. Moreover, we estimated the amount of submerged marine debris based on the fishing vessels at the collection sites surveyed two or more times using a stepwise regression model. The average amount of submerged marine debris estimated by the model was 6.0 tonnes more than that by the removal project, for which the error was ~26.5% compared to the amount collected by the removal project. The estimation method for submerged marine debris developed in this study can provide crucial information for an effective collection project by suggesting areas that require a collection project for submerged marine debris based on the information of fishing vessels.

Abstract:

Abstract Marine debris is a serious problem around the world. The entry of garbage into the sea not only threatens the survival of various marine organisms but also disturbs fishing activities, thereby reducing fishermen’s production and income. This study aimed to identify the fishing gear damaged by marine debris during fishing operations and analyze how much the marine debris impacted the production of various fishing units. Data were obtained from 101 fishermen operating at Ambon Bay by observation, interview, and descriptive analysis. Obstacles by the trash during fishing operations are among the trash twisted or attached to fishing gear; trash are twisted at the propeller of the boat and damage the fishing gear. On the fishing line group, the main hurdle is on the vertical hand line, where the trash are entangled at the hook; on the gill net group, the main hurdle is on the bottom gill net, where the trash are twisted to body net; and on the seine group, the main constraint is on the beach seine, where the trash are trapped in the cod end. This condition causes a decline in production, with the biggest impact on the bottom gill net, with a decrease in production of 4.38% from the average production per trip.

Abstract:

Abstract It is believed that the debris discovered in the ocean originated on land and was unintentionally and purposely transported by a river. Marine debris will accumulate on the water’s surface and sink to the bottom over time, polluting the seawater if left mismanaged. The life of marine organism will be threatened by the existence of the debris. The purpose of this study is to quantify the quantity of macro-sized marine debris generated by fishing activities. This study was carried out on Nasi Island in Aceh Besar from February to April 2022. Sampling of marine debris was carried out using the shoreline method with a 100 meter long transect. Marine debris from fishing activities identified includes types of plastic, plastic foam, cloth and wood, with a total of 179 items.

Abstract:

Plastics in marine environments undergo molecular degradation via biocatalytic and photocatalytic mechanisms. Abandoned, lost, or discarded fishing gear (ALDFG) damages marine and coastal environments as well as plant and animal species. This article reviews ghost fishing, ecological damage from marine plastics, recommended recycling practices and alternative usages of derelict fishing gear. Material mixing techniques are proposed to counteract the effect of biocatalytic and photocatalytic biodegradation within the context of plastic fish net recycling. There is a need for a new and rapid “multidimensional molecular characterization” technology to quantify, at a batch level, the extent of photocatalytic or biocatalytic degradation experienced on each recovered fishing net, comprising molecular weight alteration, chemical functional group polydispersity and contaminant presence. Rapid multidimensional molecular characterization enables optimized conventional material mixing of recovered fishing nets. In this way, economically attractive social return schemes can be introduced for used fishing nets, providing an economic incentive for fishers to return conventional fishing nets for recycling.

Abstract:

Records of anthropogenic marine debris and the threats it poses are increasing worldwide, yet we know relatively little about the distribution of benthic debris. The seafloor is the final destination for a large proportion of debris due to the degradation and sinking of items. A more detailed understanding of debris distributions in hotspots such as urbanised estuaries can help decision makers target management and remediation activities. We selected sites frequented by fishers and boaters in Sydney Harbour, an urbanised estuary, to investigate the impacts of recreational activities on debris abundance. The aim of this study was to examine variation in macro debris (>5mm in diameter) type and abundance at two habitat types (piers and non-piers). We chose five locations at various distances from the estuary mouth. In each location SCUBA teams performed fixed transects at two sites, one under a pier and one over nearby soft-sediment habitat. Debris was recovered by the divers and brought to the surface for classification and disposal. Surveys were repeated multiple times at each location between November 2019 and February 2020, recording a total of 2803 debris items over 36 survey events. Overall, piers had more than ten times the debris abundance of soft-sediment sites, and much higher proportion of debris types related to recreational fishing. Over half of the debris items in this study were plastic (65%), and approximately 70% of the total debris was classified as related to recreational fishing. This trait was most prominent in debris at sites closest to the estuary mouth, likely reflecting increased fishing activity in this area. This study indicates that policy makers and community groups in urbanised estuaries should focus monitoring, reduction, and remediation efforts near artificial structures such as piers, and that public awareness campaigns should target the behaviour of recreational users of these structures.

Abstract:

Coastal debris has recently emerged as a serious environmental pollution problem. Coastal debris can be treated using pyrolysis because it consists mainly of combustible materials like plastics (e.g., polyethylene (PE), polypropylene (PP), nylon) and wood. In this study, the pyrolysis characteristics of coastal debris were fully utilized by applying their basic data to fuel production. The initial temperature increased from 330 °C to 380 °C for the nylon fishing net coastal debris sample, from 405.01 °C to 430.08 °C for the PE fishing net coastal debris sample, from 395.01 °C to 419.96 °C for the PP rope coastal debris sample, and from 114.95 °C to 115.02 °C for the wood (bamboo) coastal debris sample. The activation rate of the global activation energy and the pre-exponential factors rose with the increasing heating rate, complementing the reduction rate constant due to the larger growth of the exponential term due to the kinetic models used.

Abstract:

Marine debris from fishing-related paraphernalia poses a threat to the survival of marine organisms, especially seabirds. Although the detrimental effects of marine debris on seabirds have been documented, studies on the extent of damage inflicted by marine debris on the seabird breeding population are scarce. Here, marine debris ingestion and entanglement damage to black-tailed gulls (Larus crassirostris) residing in South Korea were quantified. The five breeding colonies of black-tailed gulls were visited, and the frequency of ingestion and entanglement damage in adults and young were recorded. A total of 25 cases of marine debris damage were confirmed. As a result, damage by marine debris to gulls varied depending on breeding colonies. More adults suffered from entanglement damage than the young, and their most damaged parts were usually their legs. Fishing lines and hooks caused the most damage. We suggest that marine debris damage acquired in breeding colonies could affect breeding success.

Abstract:

In many coastal and marine environments, the blue economy is being developed to enhance community welfare. The possibility of a tsunami disaster, which could destroy the infrastructure supporting the blue economy, is one of the development challenges. The Sindangkerta beach and the Pamayang harbor in Tasikmalaya, West Java, Indonesia, are the two locations where this study discusses the possibility of tsunami debris occurring. Infrastructure that supports life may be threatened by tsunami debris. To ascertain the origin of the debris, a field survey was used in the study. When a tsunami is approaching, beachfront houses and fishing boats are easily swept towards land. The number and mass of houses and boats are counted. In order to calculate the magnitude of the tsunami impact force, the material stiffness of the two types of objects was also examined. The potential tsunami debris's runup and rundown directions are also estimated. The study's findings show that houses that serve as restaurants and shops for tourists predominate at the Sindangkerta tourist destination while fishing boats serve as the primary source of debris at the Pamayang fishing port. In addition, the debris dispersal area due to run-up and run-down is also depicted.

Abstract:

Abstract This study evaluated monthly accumulation rates and types of marine debris washed ashore at a recreational beach in Point Pleasant Park, Halifax Harbour, between April and September 2005. Black Rock Beach is 70 m long and a total of 2129 marine debris items were collected and sorted, representing a mean accumulation rate of 355 (±68 SE) items month-1. The total weight of debris items was only 10.8 kg (mean 2 kg ±0.4 SE), however eighty-six percent of this debris was plastic material. The types of litter found included: tampon applicators, condoms (i.e., sewage-related debris [SRD]); plastic fast food packaging, confectionary wrappers, Styrofoam fragments, plastic bottles and caps, items of clothing, soft drink cans, cigarettes and cigarette holders (i.e., recreational or land-based debris); packing bands, nylon rope and nets (i.e., shipping- or fishing-related debris). These items were generated by recreational use of the park (52%), sewage disposal (14%) and from shipping and fishing activities (7%). It is suggested that a significant reduction in marine debris at recreational beaches may arise by improving public awareness of the environmental and aesthetic impacts of marine litter and future improvements to the municipal sewage disposal system.

Abstract:

Marine debris nowadays is a serious environmental problem for the world because it can float or sink in the depths of the sea, as well as it can be end up on beaches. Therefore, this research has the general objective to characterize the marine debris generated by the artisanal fishing activity on Salaverry beach, La Libertad; where the samplings were carried out from February to July 2022. A total of 684 objects were collected, of which identified six types of marine debris with a total weight of 81.33 Kg, the plastic being of the most quantity with 425 objects and weight of 23.13 Kg. Also, the environmental impacts that marine debris cause were identified using the Leopold matrix getting the environmental factors that can suffer the greatest negative impact are fauna (149) and health (122). In addition, the marine debris that can cause the greatest impact is polystyrene foam (47), paint cans (46) and aerosol cans (45), LED lights and fishing lanterns (45), and bottles of lubricants and bleach (43).

Abstract:

Abstract Marine debris pollution has become an important issue in recent years. It has an impact on marine environment and marine life, as well as effecting human health. The objective of this study was to identify the composition of waste that was produced from the fishermen’s activities. The research was conducted in Cikidang Fishing Port, Pangandaran. The data of waste types from fishing vessel were grouped based on the vessel’s dimension. The result show that plastics dominated the waste composition, and based on the vessel dimension when compared the amount of waste generated, the amount of waste from one day fishing (small vessel) was greater than the ten days fishing (big vessel). The amount of waste generated from small vessel was 0.009 tons-1.vessel-1.year-1, meanwhile from big vessel was 0.09 tons-1.vessel-1.years-1. This indicates that the fishers habit to dispose waste not in the right place can become a potential source of marine debris pollution. Maintaining the quality of fishery products is very important starting from improving the fisherman behaviour to the fishing port facilities to achieve the sustainability fishery product.

Abstract:

During the completion of shale gas wells, bridge plug debris and debris particles are often left at the bottom of the well, which are difficult to clean up, pose a serious risk to wellbore operations, and reduce productivity. In order to solve the difficulty of cleaning the debris at the bottom of the well, a kind of wellbore cleaning tool is proposed based on the principle of negative jet pressure and liquid-solid two-phase flow theory. The finite element analysis method and laboratory test were used to verify the function of cleaning tools: the finite element method can effectively reflect the principle and process of dredging bottom debris with cleaning tools. In order to improve the applicability and fishing ability of wellbore cleaning tools, factors influencing the performance of cleaning tools were analyzed as follows: choosing high-density and low-viscosity working fluid is beneficial to improve the negative pressure effect of cleaning tools. Under the conditions of wellbore safety and economy, increasing pump pressure and displacement and reducing annular pressure can effectively increase the fishing performance of cleaning tools.

Abstract:

Entanglement in marine debris and fishing gear is an increasing problem for the world’s pinnipeds and a contributing factor in Steller sea lion (Eumetopias jubatus) injury and mortality. From 2005–2009, we surveyed (n = 389 days) two haul-outs on the central Oregon coast containing a combined median of 402 animals (range 33–1240, or ca. 1–19% of the Oregon coast population). We recorded 72 individuals entangled in marine debris (n = 70) or with ingested salmon hook-and-line fishing gear (n = 2). Of the identifiable neck entanglements, black rubber bands were the most common neck-entangling material (62%), followed by plastic packing bands (36%), nets (1.2%), yellow rubber bands (0.4%), and a flying disc (0.4%). The estimated prevalence of entanglement for individuals in Oregon was 0.34%. Juveniles were the most frequently entangled age class (60%), followed by adult females (28%), and subadult males (12%). Supply chain and industry-based solutions are needed to prevent entangling debris from entering the ocean, along with eliminating, modifying, or cutting entangling loops of synthetic material.

Abstract:

The coastal area of Banda Aceh City have the potential to be polluted by waste from the mainland as much as 45.41 tons/day. One source of land waste is the Krueng Aceh river, the river has dense residential areas and high community activities such as ports, ship repairs, traditional markets, recreation and fishing activities. This study aims to identify floating debris in the Krueng Aceh estuary. Data collection was carried out at the mouth of the river using a debris trap mounted on the ship that moves periodically and the research time was based on tidal charts. The results showed that type of marine debris found is plastic, cloth, processed wood, rubber and metal. Plastic debris is the most common debris found by 89 % on the surface of the Krueng Aceh estuary at spring tide and neap tide. The highest amount of debris is found in the morning 09.50 AM and 03.32 PM in the evening.

Abstract Run-up tsunamis have the ability to pick up debris along their path. More severe damage may result from the debris and their force of impact. Therefore, it is important to analyse the potential for debris in a tsunami-prone area. This study examines the threat of tsunami debris in Cilacap City, especially the source of debris from temporary or non-permanent buildings along the coast of Cilacap City. A site assessment was conducted to observe the existence of non-permanent buildings along with their number and characteristic. The results of the study show that the infrastructure of Cilacap City faces a serious threat from tsunami debris which is source from non-permanent buildings. The material transported by the tsunami run-up to cause debris was maximum 465 tons found in area around Pasir Emas Street cause potential debris for one-meter perpendicular to tsunami run-up direction 503 kg and generate tsunami impact force 28,284.3 N. In addition, the fishing port, Pendem fort and Pertamina oil refinery are also potentially affected by tsunami debris because each location has a significant number of non-permanent buildings.

Abstract. The accumulation of human debris in the marine ecosystem is one of the main hidden negative impacts of the economic and social development that humanity has witnessed after industrialization era which comes accompanied with the evolution of productions, the consumerism, as well as the emergence of the throw-away culture. In this paper, we studied the marine debris pollution on the seafloor of the North and Central Moroccan Atlantic waters from Tangier (35° N) to Sidi Ifni(29° N). The data were collected during two scientific trawling surveys conducted aboard the Charif Elidrissi Vessel in February–March 2015 and March 2018. The prospection operations allowed to collect a total of 329 kg of Seafloor Marine Debris (SMD) with an average abundance ranging between 16.84 ± 20 kg/km2 to 30.15 ± 43 kg/km2. The plastic materials represented the higher percentage of collected items with more than 40% followed by textile debris which mainly composed of knotted fishing ropes used by the longliners in the area. The analysis of SMD composition and their Spatio-temporal pattern combined with the environmental and socio-economic parameters of the prospected area using GIS tools showed that the majority of collected items comes from fishing activities, and the rest comes from the coastal anthropogenic activities. Then the analysis of hydrodynamic properties of the area using AVISO data showed that the horizontal current in area that controls the exchange of water from the coastal area to the ocean interior plays a major role in scattering debris in this area far from their origins to the open ocean.

Abstract:

AbstractMarine debris is known for its ubiquitousness and harmful effects on marine life. This study is the first analysis to provide information on the distribution of floating marine debris in German waters using aerial survey data collected between 2002 and 2016. During regular harbour porpoise monitoring flights, 191,167 km were covered and 26,512 floating debris items recorded (average encounter rate 0.1387 items/km). Debris was encountered more often in the North Sea than in the Baltic Sea (0.16 items/km; 0.08 items/km). The average encounter rate was higher in offshore waters than in coastal areas. Overlaps of marine debris distribution with ‘Special Areas of Conservation’ are a particular reason for concern. Moreover, the spring months (March–May) were identified to be the time of the year with the highest average encounter rates for marine debris. Fishing-related debris was shown to contribute up to 25% of the total number of all observed items. This study shows that opportunistically collected data on marine debris from aerial surveys are valuable for identifying distribution patterns of floating debris without additional survey effort and costs. These data can be used as baseline information to inform management schemes such as the Marine Strategy Framework Directive.

Abstract:

Some 101 fur seals Arctocephalus spp. and five southern elephant seals Mirounga leonina were recorded entangled in anthropogenic debris over ten years at Marion Island, Southern Ocean. Approximately 67% of materials causing entanglement originated in the fishing industry. Polypropylene packaging straps were the most common entangling material, followed by trawl netting. Longline hooks embedded in animals, fishing line and portions of plastic were only encountered after the inception in 1996 of longline fishing in the waters around Marion Island. The incidence of entanglement of Arctocephalus spp. during the 1996-2001 longline fisheries period increased by more than 50% over that of the 1991-1996 pre-longline fisheries period. An estimated 0.24% of the populations of fur seals were entangled. The numbers of entangled M. leonina are very low. Longline fishing has had a direct, albeit small, impact on the pinniped populations

Abstract:

Accelerated contamination of habitats with debris has caused increased effort to determine ecological impacts. Strikingly, most work on organisms focuses on sublethal responses to plastic debris. This is controversial because (i) researchers have ignored medical insights about the mechanisms that link effects of debris across lower levels of biological organization to disease and mortality, and (ii) debris is considered non-hazardous by policy-makers, possibly because individuals can be injured or removed from populations and assemblages without ecological impacts. We reviewed the mechanisms that link effects of debris across lower levels of biological organization to assemblages and populations. Using plastic, we show microplastics reduce the ‘health’, feeding, growth and survival of ecosystem engineers. Larger debris alters assemblages because fishing-gear and tyres kill animals and damage habitat-forming plants, and because floating bottles facilitate recruitment and survival of novel taxa. Where ecological linkages are not known, we show how to establish hypothetical links by synthesizing studies to assess the likelihood of impacts. We also consider how population models examine ecological linkages and guide management of ecological impacts. We show that by focusing on linkages to ecological impacts rather than the presence of debris and its sublethal impacts, we could reduce threats posed by debris.

Abstract:

Abstract Indonesia has established a national action plan on marine plastic debris to tackle the issue of marine plastic debris. Because most of the marine plastic debris in Indonesia is likely due to mismanaged plastic waste, it is important to address the problem of riverine plastic river problem in Indonesia. The objectives of this study are to visually observe the condition of the river in terms of plastic pollution, to quantify plastic litter in the river, and to develop a visual counting model of plastic litter quantification. The visual counting of plastic debris (> 2.5 cm) method based on the European standard method was applied to a river in Indonesia. The main challenge was the high turbidity of the water that obstructed visual observation. The deployment of the fishing net was also not appropriate to collect debris. Most of the plastic debris was stranded on the riverbanks, indicating that the plastic flow was likely elevated due to runoff during the rainy season. Four types of plastic litter polymers were obtained, i.e., polyethylene terephthalate (PET), low-density polyethylene (LDPE), polypropylene (PP), and polystyrene (PS). The highest percentage of macroplastics is LDPE, which usually used as daily packaging (90%).

Abstract:

In recent decades, the amount of marine debris has increased in our oceans. As wildlife interactions with debris increase, so does the number of entangled animals, impairing normal behavior and potentially affecting the survival of these individuals. The current study summarizes data on two phocid species, harbor (Phoca vitulina) and gray seals (Halichoerus grypus), affected by marine debris in Dutch waters from 2010 to 2020. The findings indicate that the annual entanglement rate (13.2 entanglements/year) has quadrupled compared with previous studies. Young seals, particularly gray seals, are the most affected individuals, with most animals found or sighted with fishing nets wrapped around their necks. Interestingly, harbor seals showed a higher incidence of ingested debris. Species differences with regard to behavior, foraging strategies, and habitat preferences may explain these findings. The lack of consistency across reports suggests that it is important to standardize data collection from now on. Despite increased public awareness about the adverse environmental effects of marine debris, more initiatives and policies are needed to ensure the protection of the marine environment in the Netherlands.

Abstract:

Plastics and other marine debris have been found in the gastrointestinal tracts of cetaceans, including instances where large quantities of material have been found that are likely to cause impairment to digestive processes and other examples, where other morbidity and even death have resulted. In some instances, debris may have been ingested as a result of the stranding process and, in others, it may have been ingested when feeding. Those species that are suction or “ram” feeders may be most at risk. There is also evidence of entanglement of cetaceans in marine debris. However, it is usually difficult to distinguish entanglement in active fishing gear from that in lost or discarded gear. The overall significance of the threat from ingested plastics and other debris remains unclear for any population or species of cetaceans, although there are concerns for some taxa, including at the population level, and marine debris in the oceans continues to grow. Further research including the compilation of unpublished material and the investigation of important habitat areas is strongly recommended.

Abstract:

Plastic pollution in oceans, also known as marine debris, is a growing problem at local and global scales. Anthropogenic marine debris poses a serious threat to many marine species, both through physical harm such as ingestion or entanglement and by carrying toxins and pathogens. This debris accumulates in oceanic gyres, concentrating these effects in some specific areas. In addition, marine debris may have devastating impacts on tourism and fishing-based economies, especially where ocean currents direct this debris. Recently, a nonprofit organization called The Ocean Cleanup proposed the first large-scale in situ marine debris removal project. The Ocean Cleanup is a project attempting to use large, floating, semi-fixed screens to harness ocean currents and accumulate debris, where it can be efficiently collected and disposed of or recycled. The project currently is working on implementing itself in the “Great Pacific Garbage Patch,” in the North Pacific Gyre. We examine this project case, as it is the first organization attempting to clean up marine debris at this scale. Understanding the potential efficacy and limitations of The Ocean Cleanup Project as a case study can give critical insights into how other projects could be created in the future to address marine plastic pollution worldwide. Using SWOT (strengths, weaknesses, opportunities, and threats) analysis to assess a marine debris cleanup can inform both a nuanced evaluation of the specific case as well as provide a means to explore marine debris as a complex, global environmental problem.

Abstract:

Sections of coastline of Heard and Macquarie Islands were surveyed for marine debris in the summer of 1987–88 and 1989, respectively. These surveys were carried out at the same sites as previous surveys in 1986–87 at Heard Island, and in 1988 at Macquarie Island. The minimum rate of artefact accumulation was 13 objects per km of shoreline per year for Heard Island, and 90 objects per km of shoreline per year for Macquarie Island. Drift-cards, released from known locations and collected on the two islands, show a similar artefact catchment area.Plastic litter was a major component of the debris at both islands. Fisheries-related debris accounted for 40% of all artefacts on Heard Island, compared with 29% on Macquarie Island. Entanglement of Fur Seals appears to be more common at Heard Island, while plastic ingestion by seabirds appears to be more common at Macquarie Island.

Abstract:

The increasing amount of marine plastic debris (MPD) poses risks of ingestion, entanglement, and transport of alien species. A new ecosystem called the “plastisphere” is currently being studied, but relevant research on it is limited. In this study, we analyzed the frequency of appearance of macroinvertebrate species on MPD. Macroinvertebrates attached to MPD were collected once every three months from March to December 2021 in eight regions. MPD in the form of aquaculture and fishing gear was detected most frequently during the study. In total, two phyla, 14 orders, 19 families, and 41 species of attached macroinvertebrates were detected during the study. There were more attached macroinvertebrate species, and they were more frequent, on fishing/aquaculture MPD (sea origin) than packaging MPD (land origin). Most fishing/aquaculture MPD is made of softer or rougher materials than packaging MPD and has a longer exposure time in the sea. In particular, the alien species Mytilus galloprovincialis was found on all longer-exposure MPD. These findings suggest that the macroinvertebrates attached to MPD are affected by the duration of exposure to the water and the characteristics of the MPD material. Therefore, in the future, fishing/aquaculture MPD could be used as an indicator for monitoring MPD-attached organisms.

Abstract:

Marine debris is ubiquitous across the global ocean and is an increasing threat to human health, economies, habitats, and wildlife. While local to national action plans are important in addressing this issue, they do not necessarily reflect the needs of coastal communities most heavily impacted. Remote island and coastal communities, particularly in Alaska, do not generate the majority of marine debris impacting their ecosystems; however, they are often left with the task of removal and disposal. Thus, the detrimental effects of marine debris are not only an ecological problem but an issue of environmental justice. This project aimed to catalyze the inclusion of place-based knowledge in marine debris solutions for St. Paul Island, a predominantly (>85%) Alaska Native community in the Bering Sea. We interviewed 36 community members during 2017–2020, documenting their observations of marine debris types, amount, distribution, and impacts over recent decades. Participants reported increasing plastic debris since the 1980s, particularly plastic bottles and fishing gear. Nearly 80% expressed concern about impacts to subsistence resources, including entanglement and ingestion. St. Paul Island community members’ experiences highlight that solving marine debris issues requires broader policies and mitigation strategies addressing sources of debris and advancing environmental justice by impact reduction. Furthermore, this case study can serve as an example of how locally relevant action plans can be developed in other coastal communities around the world by including knowledge and concerns of community members, as they are the most heavily and personally impacted by the marine debris on their shorelines.

Abstract:

The consequences of plastic debris in the marine environment were reviewed, and possible solutions were presented. The extent of marine plastic debris-related problems surpasses many other marine problems, as plastics may be transported globally and no unaffected areas seem to exist. Many animal species are in risk, most commonly studied are the effects on marine mammals and seabirds. Marine plastic debris creates new concerns such as entanglement, ghost fishing, and impaction of digestive tracts in animals. It also increases the severity of already existing concerns such as transport, exposure and uptake of organic pollution, with reduced fitness and impaired reproduction and increased mortality rates as consequences. To alleviate the problems, reducing the extent of marine plastic pollution is critical. Possible methods were identified as collecting and incentivizing recycling of marine plastic debris; redirecting production from petroleum plastics to biodegradable varieties; increase public awareness to reduce marine littering; stricter enforcement of current legislation as well as implementation of stricter legislation and harsher penalties for breaking it.Asian J.

Abstract:

Abstract Interactions between fishing vessels and oil and gas infrastructure can result in damage to fishing gear, loss of fishing time/access, and risks to crew health and safety. The spatial and temporal patterns characterizing previous incidents (and subsequent losses) between fishers and oil and gas infrastructure were quantified and used to identify key risk factors associated with fisheries losses. Between the years 1989 and 2016, 1590 incidents that resulted in a financial loss, vessel abandonment, or an injury/fatality for UK commercial fishers were recorded. The annual number of recorded incidents decreased by 98.6% over a 27-year period. The majority of past incidences resulted in financial losses (rather than injuries or fatalities) and were associated with interactions between single otter trawlers and oil and gas production-related debris. The odds of an incidence occurring varied according to substrate type and fishing intensity. A risk-model for pipeline–fishing interactions in the Fladen Ground showed that there was significant spatial heterogeneity in the risk of an incident along a pipeline according to the angle and intensity of fishing. The results highlight the need to include the full spectrum of potential losses in fisheries impact assessments associated with the installation and decommissioning of oil and gas assets.

Abstract:

Marine debris is a global environmental problem of increasing concern. In Bali, the waste problem is becoming an emergency. With the Bali Strait threatened by pollution from marine debris, data are urgently needed. This study aimed to determine the concentration and distribution of marine debris along the coastline of Badung, Tabanan, and Jembrana Regencies. The study was conducted in February 2021 on 18 beaches with a distance of 10 km between points and 8 points near river downstream areas (estuaries) which were determined randomly. The results showed that 92% of debris were plastic waste which was classed as soft plastic (33%), hard plastic (25%), plastic straps (4%), fishing gear (0.4%), and foam (30%) with an average overall concentration of 1.32 items/m². A total of 3318 items were fragments (86.3%) and 527 items were whole (13.7%). The dominant size class of debris along coastline surveyed was 2-4 cm2 (30.21%). The highest mean concentration of marine debris was 3.84 items/m² with the dominant waste class being foam fragments with 240 items. The lowest mean concentration was 0.14 items/m². Marine debris was distributed along the coastline at different concentration levels in each region, where Badung Regency had a relative concentration value ranging from 0-20%, Tabanan Regency had a relative concentration value ranging from 0-40%, and Jembrana Regency was the most affected area with a relative concentration value of 0-100%.

Abstract:

Tuna-fishing boats based at the Cilacap Oceanic Fishing Port are potential contributors to marine debris in the Indian Ocean. Without a quantitative assessment of the types and amount of debris, port management cannot develop a strategy to address this problem. This study estimated the quantities of plastics and cartons disposed of by these fisheries in the Indian Ocean. Data were collected through observations and interviews with boat managers/owners or fishermen in the port, from August to November 2019, to evaluate the boat supplies loaded on board in the port and the waste returned to the port. The marine disposal per fishing trip (the difference between the quantity of supplies taken to sea and the quantity of waste returned to port) was calculated for 89 trips of gillnet and longline boats, for a size range of 20 to 90 GT. There was no at-sea disposal of used engine oil, rice plastic sacks, styrofoam boxes, nor plastic gallon bottles. Other plastics and cartons from consumable packaging were disposed of at sea. The estimates of the plastic waste disposed were 0.8-4.4 kg.boat-1.trip-1 or 2,143-12,024 pieces.boat-1.trip-1 while the estimates of the cartons disposed were 3.5-19.4 kg.boat-1.trip-1 or 203-1,140 pieces.boat-1.trip-1. The study concluded that fishers could easily keep the waste onboard for disposal on return to port. In addition, port management should initiate a system in which the amounts of waste returned to boats returning to port are considered in granting future port clearance to those boats.

Abstract:

Discarded fishing equipment and other fishing waste are thought to account for 27% of all ocean litter. To achieve a sustainable circular blue economy, working closely with all stakeholders to eliminate waste and preserve marine ecosystems is crucial. By integrating data, technology, and waste reduction into business processes, businesses can adopt more sustainable practices and reduce the impact of plastic pollution in the ocean. This paper promotes circularity and recyclability through a blue circular economy approach. The primary objective is to establish a digital chain of custody that traces the transformation of marine debris from fishing operations into secondary raw materials. A case study is presented, highlighting the active involvement of fishermen in the recycling process. The paper introduces a framework for evaluating organisational collaboration in adopting circular economy strategies and incorporating knowledge into their business processes. The solution encompasses a data governance approach and a digital chain of custody, facilitating stakeholder collaboration towards a shared objective.

Marine debris assessment gives information about their quantity, type, and composition, which provides data to help with their management and control. The authors conducted two surveys at three beaches at Sam Son, Hai Tien, Hai Hoa) in Thanh Hoa province in March 2020 and July 2020, respectively, during an inactive and active tourism period. A total of 3,803 waste units were collected for assessment, of which plastic waste accounts for more than 98%. The density of marine debris at the idle time of tourism ranged from 0.25–1.21 items/m2. But the active tourist season recorded from 0.52–1.4 items/m2. According to the Clean Coast Index (CCI), the cleanliness of beaches was grade from average clean (i.e., Hai Tien) to filthy (i.e., Hai Hoa). The plastic debris present at these beaches was mainly porous waste derived from fishing boats and food preservation foam boxes. The results also showed that the marine debris was composed of 77% polystyrene (PS), 17% polypropylene (PP) and 6% high-density polyethylene (HDPE). The water parameters were lower than the critical values during the study period according to the QCVN 10-MT:2015/BTNMT for both periods, which indicated the coastal water quality was still suitable for recreational activities.

Abstract:

Three male sperm whales (Physeter macrocephalus) stranded on the island of Andøya in northern Norway in 2020. This created an opportunity to do gross necropsies with a focus on stomach contents as the diet of sperm whales in Norwegian waters is poorly understood and also to study potential presence of marine debris. Four new prey types for sperm whales in Norwegian waters were identified: (1) angler fish, (2) Atlantic cod, (3) cartilaginous fish, and (4) cock-eyed squid. In general, the results support earlier studies of male sperm whale diet in high latitude foraging grounds in the North Atlantic consisting of a mixture of cephalopods and meso- and bathypelagic fish. The only type of marine debris found was part of a fishing line. Based on estimates from teeth, the whales were 25, 45, and 49 years old. The size of all individuals was smaller than the median length based on whaling data for these age classes caught in Iceland in the 1970s.

Abstract:

During the 2005 leg of the MEDITS trawl survey, benthic anthropogenic debris around the Maltese Islands (central Mediterranean) was quantified for the first time, with the aim of studying its abundance and distribution in the area. 357 items were sampled from 3.5 km2 of swept area. Each item was recorded, measured and its planar and surface areas were estimated. Plastic (47%), metal and glass (13% respectively) were the most prevalent types of litter in terms of number. Limestone slabs, sacks and fabric were the items with the highest planar and surface area per item. This suggests that it is also important to consider the size of debris items as well as numerical abundance in assessing impact of litter on benthic organisms. An attempt was made to correlate anthropogenic and environmental variables, including fishing activities and wave parameters, to litter abundance and distribution but no interpretable correlations were found, implying that litter abundance and distribution depends on factors other than those considered.

Abstract:

Abstract. The Aleutian Ridge, in the western part of the Aleutian Arc, consists of a chain of volcanic islands perched atop the crest of a submarine ridge with most of the active Quaternary stratocones or caldera-like volcanoes being located on the northern margins of the Aleutian Islands. Integrated analysis of marine and terrestrial data resulted in the identification and characterization of 17 extensive submarine debris avalanche deposits from 11 volcanoes. Two morphological types of deposits are recognizable, elongate and lobate, with primary controls on the size and distribution of the volcanic debris being the volume and nature of material involved, proportion of fine grained material, depth of emplacement and the paleo-bathymetry. Volume calculations show the amount of material deposited in debris avalanches is as much as three times larger than the amount of material initially involved in the collapse, suggesting the incorporation of large amounts of submarine material during transport. The orientation of the collapse events is influenced by regional fault systems underling the volcanoes. The western Aleutian Arc has a significant tsunamigenic potential and communities within the Aleutian Islands and surrounding areas of the North Pacific as well as shipping and fishing fleets that cross the North Pacific may be at risk during future eruptions in this area.
