Abstract (sommario):

The marine meteorology, as a branch of meteorology, a science developed in the 18th and 19th century, has certain characteristics and its own terminology. Although words denoting natural phenomenon existed long before the science, a comparison between English and Romanian terminology in the 18th and 19th century is to establish the similarities and differences between words with the same meaning that entered the scientific vocabulary or were formed in the period mentioned.

Abstract (sommario):

Traffic and sea shipping industry are perhaps the most important economic activities in modern economic and social development of the world. Basic features and the meaning of sea shipping industry, as one of the constituent parts of multimodal transport, emerge primarily from special characteristics of the sea as a transportation way. Ports represent a great economic power; they play an essential role in the international and national economies, as well as in the global commodity exchange. They are of special importance because they are primary starting points for marine economy development. Numerous factors are relevant for the role and development of ports and port systems, and the most important ones include natural characteristics of ports, such as the depth and spatiality of the port maritime zone, shelter from winds, waves, sea currents and tides, and climate features. The recognition of the importance of meteorology for maritime activities has even changed the schooling of seamen; educational programme have been adjusted according to WMO recommendations, ships have been equipped with the state-of-the-art meteorological and navigational devices, and once the satellites were introduced the meteorological service has reached a high level of development and forecast accuracy. Therefore, marine meteorology should not be neglected; it should be given as much importance so as to become a constituent part of the skill for choosing the best and optimal shipping route. Marine meteorology (which includes the river meteorology as well) provides weather information to various maritime and river transportation activities. First of all, it refers to information on the state of wind and sea. Considering the importance of understanding the weather and climate of the area where a port is located, this paper provides a detailed overview of the climatological elements, including wind roses, for each of the presented ports: Rijeka, Zadar (Gaženica), Split (North Port), Ploče and Dubrovnik (Gruž).

Abstract (sommario):

Georg von Neumayer achieved outstanding scientific results and created the organisational framework for the successful completion of scientific tasks. Returning from Australia, Neumayer aimed to set up in Germany a state-owned centre for marine meteorology, hydrography, navigation, marine instruments and geomagnetism, with an emphasis on scientific research with practical application of the findings. Since 1868, a successfully operating private institute, Norddeutsche Seewarte, had existed in Hamburg. This institute provided instructions for sailing routes and the optimal use of favourable winds and currents. In 1875, the institute was transformed into an imperial institution, the ‘Deutsche Seewarte’ (German Marine Observatory), with a broad spectrum of marine responsibilities including meteorological forecasts and warnings, data acquisition and management, and climatology. Its first director was Georg von Neumayer, who led it to worldwide recognition. In 1903, he retired but the Deutsche Seewarte continued in his spirit. At the end of World War II, the institute was destroyed by bombs and ceased to exist. Today, the tasks are shared between Marine Meteorological Office of the Deutscher Wetterdienst specialising in the marine meteorological and related topics and the Federal Maritime and Hydrographic Agency.

Abstract (sommario):

Complex geographical position and meteorology make the SCS become high-risk area of accident. In order to prevent from accident to avoid marine pollution or minimize pollution as soon as possible in the SCS, strengthening rescue and salvage is necessary. Because of characteristics of the Marine pollution and special situation in the SCS, cross-strait cooperation for marine environmental preservation in the SCS should be strengthened. In this case, cross-strait cooperation on establishing a salvage company for rescue and prevention of pollution in the SCS can integrate cross-strait salvage power to promote marine environmental preservation.

Abstract (sommario):

Marine data (especially in meteorology) are often grouped geographically using a set of numbered 10° latitude–longitude squares known as Marsden squares, which are usually attributed to William Marsden, Secretary of the Admiralty (and Vice–President of The Royal Society), who supposedly invented them early in the nineteenth century. Available records suggest that this system was in fact probably invented by Robert FitzRoy soon after his appointment as head of the British Meteorological Office in 1854. FitzRoy felt that early English work in marine meteorology was being ignored, notably by the American Matthew Fontaine Maury, who had pioneered the collecting of marine meteorological data from ship's logs. A desire to undo this wrong led FitzRoy to emphasize earlier (though abortive) British projects by A.B. Becher (in 1831) and by Marsden (probably in the 1780s), both of which involved grouping marine data geographically, though only over limited areas. FitzRoy's treatment of this earlier work seems to have created, much later, the belief that Marsden had invented the system of 10° squares. Given both Maury's and FitzRoy's desire to demonstrate priority in this field, it is ironic that the first clear proposal to collect and group data from ship's logs was made by the American (and British) natural philosopher Isaac Greenwood in 1728.

Abstract (sommario):

In the realm of air-sea interaction and marine meteorology, during a tropical cyclone (TC) worldwide since 2006, the Regional and Mesoscale Meteorological Branch (RAMMB) has issued surface wind analysis. Based on this TC’s isotach (line of equal wind speed) analysis, in this paper, much more meteorological-oceanographic (met-ocean) products are developed and value-added to these isotachs. They are, for marine meteorology, overwater friction velocity, wind stress, atmospheric vorticity and the mean vertical velocity, and for oceanography, significant wave height, drift-current velocity, wind-stress tide and wave set-up. Furthermore, in order to estimate the wind-stress induced storm surges, two case studies are presented. They are the Extremely Severe Cyclonic Storm<strong> </strong>Nargis which devastated Myanmar in May 2008 from the Bay of Bengal and in August 2023 Hurricane Idalia which impacted northeastern Gulf of Mexico coastal region of Florida.

Testo completo

Abstract (sommario):

Aircraft measurements are analysed from the “First Lagrangian” of the Atlantic Stratocumulus Transition Experiment (ASTEX) from south east of the Azores Islands. In this experiment, Lagrangian strategy was used and the marine air mass, that advected southward, was followed during 12 to 14 June 1992. During the experiment, the stratocumulus clouds transitioned into thin and broken stratocumulus with cumulus cloud penetrating from below. To characterise the vertical structure in the marine boundary layer the buoyancy ﬂuxes, the variances, the turbulent kinetic energy, the momentum ﬂuxes and humidity fluxes were examined. The buoyancy flux profiles were used to discover the decoupling of the stratocumulus and the sub-cloud layer. Turbulence analysis for all five flights shows that the cloud layer were decoupled from the underlying layer. In the cloud layer the buoyancy production due to longwave radiative cooling at cloud top, was the main source for driving the turbulence. In the sub-cloud layer, the variances indicate wind shear to be the main generator of turbulence for the first two days. Then, as sea surface temperature increases, buoyancy produced turbulence was more pronounced. The u-, v- and w-spectra and cospectra of wθ and uw give insight into the typical eddy sizes, and how the peak wavelengths vary with height. The peak wavelengths in sub-cloud and cloud layer were larger than layer depth and u- and v-spectral peak wavelengths often larger than the peak wavelength from w-spectra. While peak wavelengths in the sub-cloud layer vary with the height above the surface, they are approximately invariant with height in the cloud layer.

Abstract (sommario):

The vertical structure in the coastal marine atmosphere has been investigated using data from aircraft measurements performed along the Blekinge coast. The present data are from the third of October 1990. The main feature is fairly homogeneous horizontal conditions and a subceeing boundary layer which lowers from 600 meters down to about 50 meters during the day. The turbulence were found to be in a decreasing state. The turbulence parameters were normalized using normal stationary scaling, in order to compare with other results.

Abstract (sommario):

Two days in May 1997 has been studied. During one of the days a sea breeze circulation occured, and the two days were compared in search for effects from the sea breeze on the ﬂuxes in the marine boundary layer. Measurements were made on a tower at the small island Östergarnsholm east of the island Gotland, and by an instrumented aircraft over the sea east and west of Gotland. The direction of the geostrophic wind were about northwest during the time period, but 17 m/s during May 3 and 7 m/s during May 4. The stratiﬁcation was stable over the main part of the Baltic sea because of the large temperature differences between land and sea surfaces. But as the sea breeze developed and the wind direction turned to the southeast, the stratiﬁcation at Östergarnsholm changed to near neutral. Both the wind speed and the ﬂuxes decreased with distance from the Swedish mainland and the west coast of Gotland, and the ﬂuxes were over all very small. The momentum ﬂux showed no big difference between the days. Because of the decrease with the distance from the coast and the wind speed it was concluded that the stratiﬁcation was of greater importance than the sea breeze circulation for the momentum ﬂuxe. But the heat flux was affected by the sea breeze. Because of the sea breeze the stratiﬁcation became neutral, and thus the heat ﬂux very small. The presence of swell in the baltic sea was also studied. The correlation coefficient gave unexpected result during May 3, with no difference for swell and no swell conditions. The angle between the swell and the wind wave was about 90° during both days, and could not be the reason for the difference. During the May 3 the stratiﬁcation was mostly stable, while it on May 4 was unstable. It is suggested that this could be a reason for the behaviour of ruw.

Mickle, Fraser. "The Seasonal Distribution of Marine and Non-Marine Fungi Along the New River Estuary". NSUWorks, 2000. http://nsuworks.nova.edu/occ_stuetd/312.

Testo completo

Abstract (sommario):

A number of studies have investigated the distribution of higher marine fungi in temperate estuarine systems. However, little is known of the distribution of higher marine fungi along tropical and subtropical estuarine salinity gradients and how the species composition may change seasonally. The purpose of this study was to examine the distribution and seasonal occurrence of higher marine fungi along a salinity gradient in a subtropical waterway, the New River estuarine system in southern Florida. In addition, a number of physical parameters such as water temperature, salinity, dissolved oxygen and pH were measured. Five stations were established along the New River waterway. Mean salinity ranged from 2 ppt at the most freshwater station (station 1) to 32 ppt at the highest salinity station (station 5) . Physical parameters were measured every two weeks at each station. The substrates employed for fugal collection were wood panels of a hardwood, white oak (Quercus alba) and a softwood Douglas fir (Pseudotsugu menziessi). Four sets of panels were submerged at each station. One pair was removed every three months, at each station, for a period of one year. Thirteen species of fungi were identified during the course of the study. The Ascomycotina were represented by four species and the Deutermycotina were represented by nine species. Some fungal species displayed a physiological preference for higher saline waters. Trichocladium achrasporum was only isolated from station 5, with the highest salinity (32 ppt). Three known terrestrial species (Alternaria sp., Aspergillus sp. and Penicillium sp.) were isolated from the station that exhibited the lowest salinity, station 1 (2 ppt). These terrestrial species may be considered as contaminant species. Verruculina enalia, a known marine species (Kohlmeyer and Kohlmeyer 1979), was isolated from only the lower salinity regions and not the higher salinity sites. The distribution of fungal species did not appear to follow any seasonal pattern however patterns of succession were discernible. During the first period fungal diversity was at a maximum. Diversity gradually decreased with time consistent with previously observed successional patterns (Dix and Webster 1995). Compared to temperate studies of marine fungal distribution (Kirk and Brandt 1980, Kirk and Schatz 1980, Shearer 1972) species diversity was relatively low. The main theme of this study was dominance. Halosphaeria quadricornuta and Verruculina enalia were the two dominant species. The ascocarp frequency of Halosphaeria quadricornuta was inversely proportional to Verruculina enalia. This abundance pattern may suggest interference behavior.

Abstract (sommario):

In her important and pioneering work on Robert Boyle’s contributions to chemistry Marie Boas Hall (Boas 1958; and Hall 1965, 81–93) portrayed Boyle’s advances as being tied up with and facilitated by his adoption of the new world view, the mechanical or corpuscular philosophy, as opposed to Aristotelian or Paracelsian philosophies or world views. In recent decades such a reading has been challenged. Historians of chemistry such as Frederic L. Holmes (1989), Ursula Klein (1994, 1995, 1996) and Mi Gyung Kim (2003) have portrayed modern chemistry as emerging in the seventeenth century by way of a path closely tied to technological and experimental practice and relatively independent of overarching philosophies or world views. Such a perspective raises questions about how productive Boyle’s attempts to wed chemistry and the mechanical philosopher were as far as the emergence of modern chemistry is concerned. This is the issue I will investigate. In recent work on Boyle’s chemistry William Newman (2006) has also taken issue with what he calls the “traditional accounts,” especially that of Hall. Newman’s quarrel with the traditional accounts is the extent to which they read Boyle’s corpuscular chemistry as emerging out of the atomism of Democritus and Lucretius and its reincarnations in the hands of early mechanical philosophers such as Descartes and Gassendi, neglecting a corpuscular tradition that has its origins in Aristotle’s Meteorology. In a range of detailed and pioneering studies Newman (1991, 1996, 2001, 2006) has documented the elaboration of the latter tradition in the works of the thirteenth century author known as Geber and its passage to Boyle, especially via Daniel Sennert, a Wittenburg professor of medicine in the early seventeenth century. While Newman’s work has led to a substantial and significant re-evaluation of the sources of Boyle’s corpuscular chemistry there is a sense in which he does not break from the “traditional” view insofar as he reads the revolutionary aspects of Boyle’s chemistry in terms of a change from an Aristotelian to a mechanical matter theory.

Abstract (sommario):

In 1912 a German Meteorologist, Alfred Wegener, took the drastic step of moving into another science altogether by publishing the shocking geologic theory that our continents have been sailing across the surface of the earth like leaves on a lake blown by—what? The geologists laughed at the suggestion of an impossible wind and scorned the man who had insolently crossed the boundaries of the sciences. But truth be told, it wasn’t unheard of in those early years to do just that. Rutherford, a physicist, had won the Nobel Prize in chemistry, and Marie Curie had already won twice, once in physics and once in chemistry. Wegener himself had done his PhD work in astronomy before switching over to meteorology, and at the same time was a renowned arctic explorer. The separation between the sciences are useful and real—a biology student has enough to learn without spending years on tensor analysis or relativity— but at their boundaries they blur. Today nearly everyone pays lip service to what we call interdisciplinary research, but in practice they fight hard against it. I did my PhD course work in the chemistry department of the University of Florida and my research in the physics group at Oak Ridge, then had a postdoc appointment in the chemistry department at Brookhaven before going to physics at Cornell and ending up in geology at Miami, but I had to fight along the way. A chemistry professor at Florida tried to insist that I take his colloid course instead of relativity (which was taught at the same time). I won that fight but lost at Cornell when I tried to have my students take chemistry courses instead of the required engineering and physics courses. The fact that Wegener wasn’t a geologist gave them an easy way out: it’s easier to laugh at new ideas than to confront them, and easier still to laugh at new ideas from those whom you can consider amateurs.

Abstract (sommario):

The observation at sea for marine meteorology is achieved by weather reports from merchant ship’s crew every 3 or 6 hours, mainly. However, the number of available observation data is insufficient for weather forecasting and marine environmental simulation, compared with landside. Nowadays, the special data collection function is required if the automatic observation data collection system is installed on ship. But, it is difficult to install special equipment onto general merchant ship. Therefore, we develop a prototype marine observation system, which can be installed various types of ships easily without any special data collection function for improving data collection source and/or period of the observation at sea. In this paper, a) the configuration of high reliability and durability marine observation system by using general-purpose PC and general meteorological / oceanographic sensors, b) outlook of utilizing the data, which collected by this system, are described.

Abstract (sommario):

For solar irradiance forecasting, the operational numerical weather prediction (NWP) models (e.g. the North American Model (NAM)) have excellent coverage and are easily accessible. However, their accuracy in predicting cloud cover and irradiance is largely limited by coarse resolutions (> 10 km) and generalized cloud-physics parameterizations. Furthermore, with hourly or longer temporal output, the operational NWP models are incapable of forecasting intra-hour irradiance variability. As irradiance ramp rates often exceed 80% of clear sky irradiance in just a few minutes, this deficiency greatly limits the applicability of the operational NWP models for solar forecasting. To address these shortcomings, a high-resolution, cloud-assimilating model was developed at the University of California, San Diego (UCSD) and Garrad-Hassan, America, Inc (GLGH). Based off of the Weather and Research Forecasting (WRF) model, an operational 1.3 km-gridded solar forecast is implemented for San Diego, CA that is optimized to simulate local meteorology (specifically, summertime marine layer fog and stratus conditions) and sufficiently resolved to predict intra-hour variability. To produce accurate cloud-field initializations, a direct cloud assimilation system (WRF-CLDDA) was also developed. Using satellite imagery and ground weather station reports, WRF-CLDDA statistically populates the initial conditions by directly modifying cloud hydrometeors (cloud water and water vapor content). When validated against the dense UCSD pyranometer network, WRF-CLDDA produced more accurate irradiance forecasts than the NAM and more frequently predicted marine layer fog and stratus cloud conditions.

Abstract (sommario):

Committee Mandate Concern for descriptions of the ocean environment, especially with respect to wave, current and wind, in deep and shallow waters, and ice, as a basis for the determination of environmental loads for structural design. Attention shall be given to statistical description of these and other related phenomena relevant to the safe design and operation of ships and offshore structures. The committee is encouraged to cooperate with the corresponding ITTC committee. Introduction and Metocean Forcing Environment Committee of ISSC, by its Mandate, deals with the Metocean environments. “In offshore and coastal engineering, metocean refers to the syllabic abbreviation of meteorology and (physical) oceanography” (Wikipedia). Metocean research covers dynamics of the oceaninterface environments: the air-sea surface, atmospheric boundary layer, upper ocean, the sea bed within the wavelength proximity (~100 m for wind-generated waves), and coastal areas. Metocean disciplines broadly comprise maritime engineering, marine meteorology, wave forecast, operational oceanography, oceanic climate, sediment transport, coastal morphology, and specialised technological disciplines for in-situ and remote sensing observations. Metocean applications incorporate offshore, coastal and Arctic engineering; navigation, shipping and naval architecture; marine search and rescue; environmental instrumentation, among others. Often, both for design and operational purposes the ISSC community is interested in Metocean Extremes which include extreme conditions (such as extreme tropical or extra-tropical cyclones), extreme events (such as rogue waves) and extreme environments (such as Marginal Ice Zone, MIZ). Certain Metocean conditions appear extreme, depending on applications (e.g. swell seas are benign for recreational sailing, but can be dangerous for dredging operations and are extreme for vessels transporting liquids). This report builds on the work of the previous Technical Committees in charge of Environment. The goal continues to be to review scientific and technological developments in the Metocean field from the last report, and to provide context of the developments, in order to give a balanced, accurate and up to date picture about the natural environment as well as data and models which can be used to accurately simulate it. The content of this report also reflects the interests and subject areas of the Committee membership, in accordance with the ISSC I.1 mandate. The Committee has continued cooperation with the Environment Committee of ITTC and with ISSC Committee V.6 Ocean Space Utilization. The Committee consisted of members from academia, research organizations, research laboratories and classification societies. The Committee formally met as a group in person two times before the COVID onset: in Glasgow, Scotland on the 9th of June 2019, before the 38th International Conference on Ocean, Offshore and Arctic Engineering (OMAE 2019) and in Melbourne, Australia on the 10th of November 2019, following the 15th International Workshop on Wave Hindcasting and Forecasting. It’s also held a number of regular teleconferences: two before the face-to-face meetings and seven after, once international travel was stopped by the pandemic. Additionally, Committee members met on an ad-hoc basis during their international travels in 2019. With the wide range of subject areas that this report must cover, and the limited space, this Committee report does not purport to be exhaustive; however, the Committee believes that the reader will be presented a fair and balanced view of the subjects covered, and we recommend this report for the consideration of the ISSC 2022 Congress. The report consists of 11 Sections: two of which include the Introduction and Conclusions, and nine are the main content. The opening Section 1 outlines and defines Metocean Forcings which can affect the offshore design and operations and are the subject of this Review Chapter. The review of publications starts from progress in Analytical Theory in 2018-2021, Section 2. It covers the basic framework of experimental, numerical, remote sensing and all the other methods and approaches in Metocean science and engineering. Numerical Modelling (Section 3) is one of the most rapidly developing research and application environments over the past two decades, it allows us to extend the theory when analytical solutions are not possible, and to complement (or even replace) some of the experimental approaches of the past. Computer simulations will always need verification, validation and calibration of their outcomes through experiments and observations, particularly in engineering applications and offshore Metocean science. Therefore, Section 4 (Measurements and Observations) is the largest in the Chapter. Section 5 is effectively a modern extension of the measurement section – it is dedicated to Remote Sensing. Over the last four decades, the remote sensing has both become a powerful instrumental tool for field observations and remains an active area of engineering research in its own right as we see through growing developments of new capabilities in this space. While the first five chapters are broadly dedicated to direct outcomes of Metocean research, the rest of the chapters focus more on analysis and indirect outputs. With mounting amounts of collected data: numerical, experimental, remote sensing, - Section 6 discusses advances in Data Analysis, and Section 7 in Statistics, its Theory and Analysis. Section 8, on Wave- Coupled Phenomena, reflects one of the most rapidly developing areas in Metocean science, particularly important in our era of numerical modelling. It accommodates various topics of interactions between small-scale phenomena (waves) and large-scale processes in the air-sea environments: wave breaking, wave-current and wave-ice interactions, wave influences in the Atmospheric Boundary Layer (ABL) and in the upper ocean, and complex wave-coupled modelling in the full combined air-sea-ice-wave system. Most essential for offshore engineering, is modelling and understanding of Extreme Events and Conditions, which are the subject of Section 9. Last, but not the least, Section 10 discusses Wind-Wave Climate which is connected to the global climate change. This connection is threaded throughout other sections of the chapter and is of utmost significance in offshore Metocean design and planning.

Abstract (sommario):

A PWR reactor coolant system is a highly complex physical process: heterogeneous power, flow and temperature distributions are difficult to be accurately measured, because instrumentations are limited in number, thus leading to the relevant safety and protection margins. This situation is in many ways similar to climate and weather models: a complex process that is not possible to sample and measure as finely as wanted. Meteorology and climate sciences have adapted and improved the Data Assimilation techniques in order to improve the accuracy of description and prediction in their fields. EDF R&D is seeking to assess the potential benefits of applying Data Assimilation to a PWR’s RCS (Reactor Coolant System) measurements: is it possible to improve the estimates for parameters of a reactor’s operating set-point, i.e. improving accuracy and reducing uncertainties of measured RCS parameters? In this paper we study the feasibility of enhanced estimation of PWR primary parameters, by using twin experiments for assessing Data Assimilation benefits. We simulated test samples with a 0D-Model, and used these samples in a Monte-Carlo approach to get background terms for Data Assimilation. This successful preliminary study will lead to further assessments with real plant data.

Abstract (sommario):

Abstract This article aimed to analyze the relevance of wind and solar energy for the supply of artificial lifting systems on offshore platforms in the Brazilian equatorial region. The scope encompassed a detailed technical and environmental assessment, with an emphasis on the integration of a 10 MW floating photovoltaic power (FSPV) system to meet the demand for 10 pumps. In addition, the study sought to evaluate the potential for solar power generation in the region, considering the abundant global horizontal solar radiation (GHI). The methodology employed involved a thorough evaluation of the energy required for the artificial lifting system, using nine steps as described by Centrilift. For the analysis of solar power generation, the System Advisor Model (SAM) developed by the National Renewable Energy Laboratory (NREL) was used. The meteorological data and wind potential were obtained from measuring stations of the National Institute of Meteorology (INMET). Through SAM, FSPV performance has been carefully modeled, considering different scenarios to determine the viability of the power solution. The results obtained highlighted the high viability of the 10 MW FSPV system to meet the energy demand of the 10 artificial lifting pumps. The simulations carried out in the SAM indicated a significant annual generation of electricity, with a high supply capacity and a good performance index, ensuring an adequate and sustainable energy supply over time. In addition, the analysis revealed the promising potential of solar power generation in the equatorial region, consolidating FSPV as the most appropriate option and with the best prospects for offshore platforms in this location. This study provides valuable information by highlighting the feasibility of floating solar energy as a viable energy solution for offshore platforms in the Brazilian equatorial region. The integration of the FSPV system was thoroughly evaluated, demonstrating the benefits of the abundant availability of solar radiation, as well as the modulation and scalability of the systems. In addition, the environmental impacts associated with both energy sources were identified, underscoring the importance of mitigating any possible negative effects. The study presents an in-depth and reasoned analysis, offering valuable guidance for future renewable energy projects in regions of similar characteristics.

Abstract (sommario):

Research cruise AL579 is part of the bachelor course "Physics of the Earth System - Geophysics, Meteorology and Oceanography" at the University of Kiel. It is the field exercise for marine geophysics and hydroacoustics. The aim of the annually recurring cruise is to give students a practical insight into the acquisition, processing, documentation, and interpretation of marine geophysical data. AL579 took place from August 20th -28th 2022 with the main study areas in Eckernförde Bay and the Bay of Mecklenburg. Parts of the scientific crew changed during a stopover in Kiel on Wednesday, 24.8.2022. In Eckernförde Bay we mainly collected Multibeam Echosounder (MBES) and INNOMAR Subbottom Echosounder (SES) data calibrated by CTD measurements close to the pockmark field off Mittelgrund. On Wednesday, 24.8.2022 we tested a new Ocean Bottom Seismometer (OBS) prototype. In the Bay of Mecklenburg, the focus was on Blinkerhügel and the seafloor structures further west where an enigmatic stone structure was discovered in 2021. This area was surveyed with Sidescan Sonar, MBES, SES, and CTD measurements and several video transects with an underwater drone. We also collected two sets of multi-channel seismic data to investigate the deeper structures of the Western Baltic Sea and the Bay of Mecklenburg.

Abstract (sommario):

Estamos ante una encrucijada global de proporciones nunca vistas. El planeta se calienta más rápido de lo esperado y enfrentamos condiciones climáticas cada vez más extremas, lo que pone en riesgo la sostenibilidad de la vida humana en el mediano y largo plazo. El nivel de los océanos está aumentando, los arrecifes de coral están muriendo, las especies se están extinguiendo, los glaciares se están derritiendo y las condiciones climáticas extremas se hacen cada vez más frecuentes con intensas olas de calor, inundaciones, huracanes, incendios y/o sequías. Para hacer frente a esta compleja situación, todos, personas e instituciones en los ámbitos nacional, regional y global, tenemos que hacer nuestra parte para evitar llegar a un punto de no retorno. Aunque Colombia solo genera el 0,6 % de los gases de efecto invernadero (GEI), es uno de los veinte países más amenazados por la crisis climática. Nuestro país alberga el 50 % de los páramos del mundo y es catalogado como una potencia en agua, biodiversidad y ambiente, aloja alrededor del 10 % de la fauna y flora del mundo, teniendo por ello un rol central en los esfuerzos globales que se realizan para mitigar los efectos del cambio climático. También es reconocido por ser el segundo país con más alta presencia en biodiversidad en la tierra, goza de dos océanos, cinco vertientes hidrográficas, ríos, lagunas y ciénagas, siendo de esta manera el agua un recurso fundamental para el desarrollo de las generaciones futuras. El país cuenta con grandes extensiones de páramos, los cuales son la fuente del 70 % de agua dulce en nuestro país y comparte al sur de nuestras fronteras con la Amazonía, considerada la selva tropical más extensa del planeta y el pulmón del mundo. Una porción representativa de ese 10 % del total de la biodiversidad mundial que tiene nuestro país, se encuentra dentro del Sistema Nacional de Áreas Protegidas (SINAP), del que hace parte el Sistema de Parques Nacionales Naturales y las Reservas Forestales (más de 17 millones de hectáreas), una fuente importante de bienes y servicios ecosistémicos, entre los cuales, el suministro del recurso hídrico incluye más del 62 % de los nacimientos de los acuíferos nacionales y abastece a casi un 80 % de la población colombiana. Así mismo, protege lagunas y ciénagas que contienen el 20 % de los recursos hídricos que abastecen la generación de energía eléctrica del país. En estas áreas protegidas se conservan muestras representativas de los ecosistemas naturales marinos y continentales, los cuales, además de albergar un gran número de especies de fauna y flora, contribuyen a la regulación del clima y protegen las cuencas hidrográficas. Es así como por su especial importancia ecológica, los Parques Nacionales Naturales tienen la función de conservar, proteger y salvaguardar sus ecosistemas de especial valor por medio del Estado y de los particulares. Esta gran riqueza ambiental del país está siendo amenazada por el uso indebido de los recursos naturales, lo que genera un acelerado deterioro de los ecosistemas, alterando su funcionalidad y poniendo en riesgo la biodiversidad. Esta problemática se ha convertido en un reto de primer orden para el Estado colombiano, sus autoridades ambientales y la sociedad en general. El Sector Defensa no ha sido ajeno a esta realidad, por lo que en el marco definido por la ley, la Presidencia de la República y el Ministerio de Ambiente y Desarrollo Sostenible, ha reconocido el potencial desestabilizador de las afectaciones causadas por las diversas actividades ilícitas de los Grupos Armados Organizados (GAO), los Grupos Delincuenciales Organizados (GDO) y ciudadanos que hacen un uso indebido de los recursos naturales. Fenómenos como la siembra de cultivos ilícitos, la extracción ilícita de minerales, la tala indiscriminada, la ganadería extensiva, el acaparamiento de tierras, la pesca ilegal, la contaminación, el vertimiento de sustancias peligrosas y el tráfico ilegal de flora y fauna, han debilitado los ecosistemas nacionales. Estas actividades ilegales afectan los recursos hídricos del país, los suelos, los páramos y la atmósfera, produciendo efectos negativos que generan deforestación, pérdida de hábitats, extinción de especies, la destrucción de fuentes de agua, el deterioro de las tierras de cultivos e impactos negativos en las reservas forestales y las áreas que integran el Sistema Nacional de Áreas Protegidas (SINAP). La degradación ambiental que hemos visto no solo es utilizada por las organizaciones criminales para obtener recursos que les permiten sostener su accionar delictivo en diversas zonas del país, más grave aún, se constituye en un atentado directo contra el porvenir de las generaciones futuras. Es por ello que el Sector Defensa ha reconocido el agua, la biodiversidad y el medio ambiente como activos estratégicos de interés nacional, con un carácter principal y prevalente, buscando apoyar con sus capacidades a las autoridades ambientales del país, con el fin de realizar acciones cada vez más eficaces contra las organizaciones criminales responsables del deterioro ambiental. Es en ese contexto surge la idea de este libro, que busca presentar la problemática que se enfrenta y visibilizar las acciones realizadas por el Sector Defensa en coordinación con las autoridades ambientales, con el fin de apoyar la defensa de estos activos estratégicos, así como prevenir los daños futuros a los mismos, en aras de trabajar en la protección de los recursos naturales, bajo una visión multidimensional de la seguridad. El Ministerio de Defensa (MDN) ha sido consciente de los desafíos climáticos a los que se enfrenta, no solo el Sector, sino el territorio nacional, en cuanto a los impactos cada vez mayores derivados de las condiciones meteorológicas extremas y la explotación de los recursos. Por ello, el Sector ha trabajado para alinearse con la Política Nacional de Cambio Climático, los compromisos del país ante la Contribución Nacionalmente Determinada (NDC), el cumplimiento del CONPES 4021 de diciembre de 2020 para el Control de la Deforestación y la Gestión Sostenible de Bosques, para así aportar con acciones de adaptación, mitigación y gestión del riesgo ante el cambio climático y variabilidad climática mediante del Plan de Gestión de Cambio Climático del Sector Defensa (PIGCCSD). Este libro reúne los principales resultados del Sector Defensa en materia de protección del medio ambiente y resalta la articulación de las políticas, así como de la operativización de las mismas por parte de las Fuerzas Militares y la Policía Nacional, por la protección de los recursos naturales de la Nación, una responsabilidad que ha quedado claramente plasmada en la “Estrategia Artemisa”, que es un esfuerzo permanente, sostenido, conjunto, coordinado, e interinstitucional que permitirá proteger y defender el agua, la biodiversidad y el medio ambiente como activos estratégicos de la Nación, a partir de la lucha contra la deforestación, sus causas directas o subyacentes y contrarrestar los efectos del cambio climático, como también la lucha contra la explotación ilícita de minerales, contra los cultivos ilícitos que afectan el medio ambiente y el conjunto de actividades de control y vigilancia que apoya nuestra Fuerza Pública para la defensa de los recursos naturales. Trabajando de forma articulada con la Fiscalía, el Ministerio de Medio Ambiente y Desarrollo Sostenible, el Instituto de Hidrología, Meteorología y Estudios Ambientales (Ideam), y la Unidad de Parques Nacionales Naturales, en diversas zonas del país, la Estrategia Artemisa ha permitido brindar apoyo a las autoridades ambientales y administrativas, para preservar y defender el agua, la biodiversidad y el medio ambiente en las áreas de reserva forestal, áreas protegidas y 59 Parques Nacionales Naturales. Mediante la Directiva Permanente 008 del 22 de marzo de 2022, el MDN institucionalizó e impartió lineamientos e instrucciones al Comando General de las Fueras Militares, la Dirección General de la Policía Nacional y la Unidad de Gestión General del MDN, con el propósito de implementar medidas, desplegar operaciones, actividades de apoyo y gestión ambiental, para la implementación de la Estrategia Artemisa. De esta forma y bajo un enfoque sostenido, conjunto, coordinado, interinstitucional y multilateral, se trabajará para incluir dentro de la doctrina militar y policial las acciones relacionadas con la protección del agua, la diversidad y el medio ambiente, al tiempo que se concentrarán los esfuerzos de inteligencia en la identificación del modus operandi de las organizaciones criminales que afectan el medio ambiente, desarrollando operaciones contra los GAO y los GDO que atentan contra el medio ambiente. Desde el 2019 a la fecha se han realizado diecisiete (17) operaciones sobre las áreas de los Parques Nacionales Naturales, especialmente en las regiones de la Amazonía y la Orinoquía, como son los Parques Nacionales Naturales (PNN) Serranía de Chiribiquete, PNN La Paya, PNN Tinigua, PNN Picachos, PNN Sierra de La Macarena, la Zona de Reserva Forestal de la Amazonía y la Reserva Natural Nukak. Se han dispuesto, para esta campaña, 22.300 hombres de la Fuerza Pública, que, desde sus respectivas unidades militares y policiales resguardan las áreas protegidas del territorio nacional. Estas unidades incluyen: 10 batallones de alta montaña (páramos), una brigada contra el narcotráfico, una brigada contra la minería ilegal, unidades de guardacostas, infantería de marina y efectivos de la Policía Nacional. El Sector Defensa es consciente de que a futuro será fundamental continuar fortaleciendo las capacidades de la Fuerza Pública para, en el marco de sus competencias, continuar apoyando a las autoridades ambientales, entes territoriales y a la comunidad en la defensa y preservación del agua, la biodiversidad y el medio ambiente como activos estratégicos de la Nación. Será fundamental profundizar la disrupción del delito de la explotación ilícita de minerales, mediante el desmantelamiento de las economías ilícitas que se lucran de ella y de la afectación de la cadena criminal. En igual medida, será vital apoyar la recuperación de los ecosistemas más afectados por las actividades ilegales, por medio de actividades de restauración de áreas, del trabajo articulado con las comunidades, la construcción y mantenimiento de viveros forestales y el fortalecimiento a las investigaciones científicas lideradas desde la Armada Nacional y la Dirección General Marítima para la protección de los océanos, el recurso hídrico y sus ecosistemas. De esta forma será posible continuar trabajando en la reducción de los riesgos que se ciernen sobre los ecosistemas del país y disminuir los índices de deforestación, y tras la búsqueda de soluciones que contribuyan a la reducción y mitigación de los GEI. Esta estrategia que ha puesto en marcha el Sector Defensa y que es recogido en esta obra, presenta los aportes sectoriales del trabajo interinstitucional que se han venido realizando en los últimos años, siendo un ejemplo de la forma en la que se pueden sumar esfuerzos para contribuir a la superación de la encrucijada global que nos afecta a todos y que debe ser enfrentada con un esfuerzo común.
