Ocean currents are instrumental in determining the climate in many regions around the world. While little is known about the effects of removing ocean current energy, the impacts of removing current energy on the farfield environment may be a significant environmental concern. The typical turbine issues with blade strike, entanglement of marine ...
The official wording of the goal is to "Conserve and sustainably use the oceans, seas and marine resources for sustainable development". [1] Marine resources include: biological diversity (marine biodiversity) ecosystem services from marine ecosystems, such as marine coastal ecosystems and coral reefs; fish and seafood; minerals (for example ...
The image to the right illustrates the high density of flow along the coast, note the high velocity white northward flow, perfect for extraction of ocean current energy. Countries that are interested in and pursuing the application of ocean current energy technologies include the European Union, [4] Japan, [5] the United States, [6] and China. [7]
A gyre is a circular ocean current formed by the Earth's wind patterns and the forces created by the rotation of the planet. [33] There are five main ocean gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre. There are significant garbage patches in each of ...
Furthermore, the ocean's function as a carbon dioxide sink, alterations in the atmosphere, ultraviolet light, ocean acidification, viral infections, the repercussions of dust storms transporting agents to distant reefs, pollutants, and algal blooms represent some of the factors exerting influence on coral reefs.
Governments have no time to lose when it comes to implementing a new global ocean treaty to protect the high seas as threats from human activities intensify, a report by environmental group ...
Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives ...
The West Indian Ocean is an area with maritime security concerns for shipping and governments. [25] Somali piracy started to increase in the early 2000s, after a civil war affected the area. [25] Between 2008 and 2013, large numbers of attacks against merchant ships in the Indian Ocean occurred, gaining international attention. [25]
