2	Protecting Biscayne: An Analysis of Strategies for the Protection of Biscayne National Park Harvey, Janell M 04 November 2004 (has links) Biscayne National Park is located off the southeast coast of Florida and attracts approximately half a million visitors annually. Managers of Biscayne National Park are proposing a new General Management Plan (GMP) in order to update the recreational and commercial use of resources in the park. A Fishery Management Plan (FMP) is also being drafted simultaneously in conjunction with the Florida Fish and Wildlife Conservation Commission in order to address concerns associated with management of fish stocks within the park. The proposed plan alternatives of the GMP and the recommendations of the FMP were developed in response to the negative impacts on the park's marine ecosystem due to exponential population growth of the adjacent Miami metropolitan area. Problems associated with decreasing water quality, habitat degradation, and species exploitation contribute to the diminishing integrity of resources in the park and surrounding area. Currently commercial and recreational fishing are allowed in most of Biscayne National Park. The National Park Service's proposed alternatives are highly complex in order to make an attempt at appeasing stakeholder interests. In addition the recommendations of the FMP join the GMP alternatives in omitting marine reserves, a management practice that is widely thought by the scientific community to be an important step in marine resource rehabilitation. At present, there is a noticeable absence of scientific information and lack of participation of scientists in management decisions. Biscayne National Park would ultimately benefit by incorporating marine reserves into the park, and adjusting them based on scientific studies conducted by an appointed Scientific Advisory Board. Partnerships with state, federal, and international agencies could promote the idea of being a part of a marine reserve network for optimal resource protection in the Caribbean. An increase in revenue from a permit system and entrance fees would also promote enforcement and protection of park resources. Simple but strong regulation in the park could also help alleviate enforcement problems. In addition education of park resource users should be expanded inside and outside the park. marine reserve marine management plan marine policy fishery management ecosystem management American Studies Arts and Humanities
3	Using Geospatial Tools to Assess Changes to Marine Ecosystems in Small Island Developing States Following Hurricane Disturbances: A Case Study of Dominica After Hurricane Maria Shields, Ryan J. 01 April 2021 (has links) Seagrass meadows, like coral reefs, are in decline globally but are often neglected in marine policy and conservation despite their equally critical ecosystem services. Both habitats can be heavily impacted by wave surges, rainfall-induced earth movement and flooding, changes to water temperature, salinity, and acidity, and increased levels of turbidity—all occurring at increased rates due to a changing global climate. We demonstrate that multispectral satellite imagery, geospatial tools, and classification techniques can be used to inform management by identifying and quantifying changes in seagrass distribution and the presence of sediment-related threats. Results from Dominica indicate near-shore seagrass habitat area increased by 195.7 hectares between 2016 and 2019, suggesting a continued expansion of Halophila stipulacea. Further analysis showed 22.4 hectares of accreted coastal sediment and 1362.2 hectares of suspended sediment captured, placing 424.4 hectares of sensitive reef area at risk of experiencing tissue abrasion or reduced photosynthetic activity. Our methods can be used by marine resource managers and policy makers to inform decisions relating to fisheries production, emissions trading, disaster risk mitigation, and invasive species monitoring, facilitating sustainable growth in the blue economy.

4	Modelling marine vessels engaged in wildlife-viewing behaviour using Automatic Identification Systems (AIS) Nesdoly, Andrea 20 August 2021 (has links) Observation of marine animals in their environment – whale-watching – has grown greatly in recent years, bringing risk to the animals. Of particular concern are harmful impacts on marine mammals, some of which are endangered. As a result, regulations have been developed for their protection, but these conservation measures require enforcement across a broad geographic region, which is difficult due to limited monitoring resources. A ship-borne information transmission system called AIS – Automatic Identification System – can provide information-rich marine vessel movement data that can be used to passively monitor vessels engaged in viewing wildlife, aiding regulatory bodies with compliance enforcement. Few studies explore the use of AIS data to determine when vessels are engaged in wildlife-viewing, and as such little guidance exists on how to implement classification models appropriately. The objective of this thesis is to use AIS data to evaluate the accuracy and utility of existing classification models to detect vessels engaged in observing wildlife, and determine whether information about species being observed can be extracted. Using a control set of observed cetacean encounter data, three classification models were statistically assessed. From this, a hidden Markov model was chosen for detailed analysis in the vicinity surrounding Vancouver Island, B.C., Canada. The resulting analysis concluded that a hidden Markov unsupervised classification approach was feasible for detecting vessel behaviours and differentiating species type. These findings suggest AIS can aid managers and the commercial whale-watching industry in making informed decisions regarding conservation regulations and their compliance. / Graduate / 2022-08-12 Automatic Identification System (AIS) Vessel behaviour classification Whale-watching Marine Management
5	Social Sustainability in Marine Governance: The Case of Barra del Colorado, Costa Rica Apéstegui, Paola January 2021 (has links) Marine issues develop in complex social contexts, usually involving a large number of sectors, actors, and users. Achieving sustainable marine governance requires a continued and context-specific structure of interdisciplinary knowledge, inter-sectorial interaction as well as inter-institutional coordination that generates daunting challenges to government, stakeholders and civil society. In this sense, it is imperative for marine governance structures to pay close attention to social sustainability factors, such as recognition of socio-cultural diversity, representation in decision-making and distribution of ‘goods’ and ‘bads’, which have commonly been overlooked in environmental governance in general and marine governance in particular. Costa Rica’s territorial sea is an important source of income for a myriad of communities on the Pacific and Caribbean coasts. During 2019 and 2020, the Responsible Fishing Marine Area and Marine Management Area of Barra del Colorado were created under the expectation of serving the social and ecological needs of the community. Taking this into consideration, this study aims to examine how social sustainability was handled in the formation process of the two resource management areas, which involved participation of institutional and civil society actors from 2010 until 2019. This study first analyses the concept of marine governance and its relationship to social justice. The concept of social sustainability is explained and I then develop a social sustainability conceptual framework. Secondly, the methodology and methods are described. The choice of the empirical case is described in the next section and I next give a brief overview of Barra del Colorado’s social and economic characteristics and background. Further, an analysis of the process to consolidate the Responsible Fishing Marine Area and the Marine Management Area of Barra del Colorado through the social sustainability framework is conducted. Last, the results of the analysis are discussed and the main findings are presented. Through this analysis, the process of consolidation was assessed against the normative social sustainability theory, concluding that the process was found lacking regarding its social sustainability due to a series of government-related issues, that affected the representation, recognition and distribution of the process.

6	Critical perspectives: North Sea offshore wind farms. : Oral histories, aesthetics and selected legal frameworks relating to the North Sea. / Kritiska perspektiv: vindkraftparker i Nordsjön : Muntlig historia, estetik och utvalda rättsliga ramar relaterade till Nordsjön Moss, Joanne January 2021 (has links) The study is developed from five in-depth interviews with individuals from different walks of life who have interacted significantly with the North Sea. The study discusses change in the North Sea specifically in the development of fixed turbine wind farms and their physical and aesthetic effects. Observations speakers make as to changes in the North Sea and as to its beauty are contextualised and discussed using NASA satellite images, photographs and review of available academic literature, UK policy documents and law. This context includes a study of the industrialised North Sea with reference to the sediment sea plumes behind monopile turbines. The United Kingdom was selected for particular study of its wind farm development permissions process, including evaluations of seascape and the requirement of independence for expert evidence. Decline of trawler access to the North Sea is referenced to wind farm growth, and to adverse changes in public opinion leading to closure of the UK Dogger Bank to trawlers. Finality of wind farm development decisions is considered against the prospect of overturn by the courts. This aspect covers the application and development of principles relating to appeal by way of judicial review in the UK jurisdictions of Scotland, England and Wales, and Northern Ireland. The study identifies, and explains the English aesthetic evaluation of wind farms. It concludes that sea plumes are the result of a legal choice to allow permit applications to succeed without testing by reference to detailed in-sea turbine dimensions. In the permissions process (a) sea plumes are not evaluated by the seascape criteria applicable to coastal or off-coastal wind farms (b) deep offshore wind farms are instead evaluated by possible changes to character of the sea. The study further concludes that (i) the open horizon of the North Sea has been lost in significant part (ii) the combined aesthetic of transience, decay, and nostalgia underlies the aesthetic of the North Sea Maunsell forts (contrasted to Sealand), and also underlies attitudes to decommissioning wind farms, and (iii) concepts of sea beauty may be based on appearance or health, being regulated by different legal regimes in each eventuality (respectively the European Landscape Convention, or the OSPAR/ biodiversity/ habitat initiatives) Aesthetics Coastal Decay Decommission Development permission European Landscape Convention Fluid dynamics Horizon Industrial Judicial review Marine management Maunsell Monopile NASA North Sea Offshore Oral history OSPAR Scotland Scour Sealand Sea plumes Seascape Sediment SPM Suspended particulate matter Transience Trawler Turbine United Kingdom Wind farm.
