Strengthening governance of ocean fishery resources
Governance of the world’s marine fisheries is ill-adapted to sustainability. Twenty years after the expansion of exclusive economic zones over most of the continental shelves, fisheries worldwide face problems of stock depletion, declining yields and increasing conflict. Other human activities in the ocean compound the effect. What is wrong? This paper is about the internal workings of fishery ...
متن کاملOcean in peril: reforming the management of global ocean living resources in areas beyond national jurisdiction.
This article presents the outcome of research aimed at assisting governments in meeting their commitments and legal obligations for sustainable fisheries, based on increasing evidence that global fisheries are in crisis. The article assesses the effectiveness of the existing legal and institutional framework for high seas living resources. It focuses on: (1) the role of regional fisheries manag...
متن کاملAssessing Global Ocean Wind Energy Resources Using Multiple Satellite Data
Wind energy, as a vital renewable energy source, also plays a significant role in reducing carbon emissions and mitigating climate change. It is therefore of utmost necessity to evaluate ocean wind energy resources for electricity generation and environmental management. Ocean wind distribution around the globe can be obtained from satellite observations to compensate for limited in situ measur...
متن کاملA Preliminary Assessment of Ocean Thermal Energy Conversion Resources
Worldwide power resources that could be extracted from Ocean Thermal Energy Conversion (OTEC) plants are estimated with a simple one-dimensional time-domain model of the thermal structure of the ocean. Recently published steady-state results are extended by partitioning the potential OTEC production region in one-degree-by-one-degree “squares” and by allowing the operational adjustment of OTEC ...
متن کاملDepartment of Ocean & Resources Engineering Seminar Newwaves, Solitons and Spreading
It is apparent that most waves in a random sea behave for most of the time in a manner consistent with simple 2nd order models based on linear dynamics. As a consequence, the average shape of a large wave crest, the scaled auto-correlation function NewWave, becomes a useful model. It captures considerable information about the overall statistical properties of the sea-state into a single isolat...
