The International Seabed Authority (ISA) is a Kingston, Jamaica-based intergovernmental body of 167 member states and the European Union established under the 1982 UN Convention on the Law of the Sea (UNCLOS) and its 1994 Agreement on Implementation. The ISA's dual mission is to authorize and control development of mineral related operations in the international seabed considered the "common heritage of all mankind" and also protect the ecosystem of the seabed, ocean floor and subsoil in "The Area" beyond national jurisdiction. The ISA is to safeguard the international deep sea, the waters below 200 meters or 656 feet, where photosynthesis is hampered by inadequate light. Governing approximately half of the total area of the world's oceans, the ISA is to exercise oversight of activities that might threaten biological diversity and harm the marine environment. The Authority operates as an autonomous international organization with its own Assembly, Council and Secretariat.
The United Nations Convention on the Law of the Sea (UNCLOS), also called the Law of the Sea Convention or the Law of the Sea Treaty, is an international agreement that establishes a legal framework for all marine and maritime activities. As of June 2016, 167 countries and the European Union are parties.
Polymetallic nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as a potential economic interest.
Bottom trawling is trawling along the seafloor. It is also referred to as "dragging". The scientific community divides bottom trawling into benthic trawling and demersal trawling. Benthic trawling is towing a net at the very bottom of the ocean and demersal trawling is towing a net just above the benthic zone. Bottom trawling can be contrasted with midwater trawling, where a net is towed higher in the water column. Midwater trawling catches pelagic fish such as anchovies and mackerel, whereas bottom trawling targets both bottom-living fish (groundfish) and semi-pelagic species such as cod, squid, shrimp, and rockfish.
The seabed is the bottom of the ocean. All floors of the ocean are known as 'seabeds'.
Marine protected areas (MPA) are protected areas of seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations, MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish. The value of MPA to mobile species is unknown.
National Marine Conservation Areas (NMCAs) is a Parks Canada programme responsible for marine areas managed for sustainability and containing smaller zones of high protection. They include the seabed, the water itself and any species which occur there. They may also include wetlands, estuaries, islands and other coastal lands. They are protected from dumping, undersea mining and oil and gas exploration and development, which may damage the aquatic or terrestrial ecosystems in the conservation area. However, not all commercial activities are prohibited in these zones. Shipping, commercial and sport fishing, and recreational activities are allowed.
The Australian Marine Conservation Society (AMCS) is an Australian environmental not-for-profit organisation. It was founded in 1965 as the Queensland Littoral Society before changing its name to the Australian Littoral Society and then finally in 1995 to its current title. It works on protecting the health and vitality of Australia's coasts and oceans.
Deep sea mining is a growing subfield of experimental seabed mining that involves the retrieval of minerals and deposits from the ocean floor found at depths of 200 metres (660 ft), up to 6,500 metres (21,300 ft). As of 2021, the majority of marine mining efforts are limited to shallow coastal waters only, where sand, tin and diamonds are more readily accessible. There are three types of deep sea mining that have generated great interest: polymetallic nodule mining, polymetallic sulphide mining, and the mining of cobalt-rich ferromanganese crusts. The majority of proposed deep sea mining sites are near polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper, manganese, cobalt, and zinc. The deposits are mined using either hydraulic pumps or bucket systems that take ore to the surface to be processed.
The Sugar Loaf Islands are a collection of five small uninhabited islands and several sea stacks near Port Taranaki, New Zealand.
Henry Tuakeu Puna is a Cook Islands politician, and the current secretary-general of the Pacific Islands Forum. He was Prime Minister of the Cook Islands from November 2010 to October 2020. Since 2006 he has been leader of the Cook Islands Party.
Kiriau Turepu is a Cook Islands politician and former Cabinet Minister. He is a member of the Cook Islands Party.
The Marine and Coastal Area Act 2011 is an Act of the New Zealand Parliament created to replace the Foreshore and Seabed Act 2004. It was brought in by the fifth National government and creates a sui generis property class for the marine and coastal area, in which it is vested in no one. This is in contrast to the Foreshore and Seabed Act 2004 in which the foreshore and seabed were vested in the Crown.
The Marine Policy of the Barack Obama administration comprises several significant environmental policy decisions for the oceans made during his two terms in office from 2009 to 2017. By executive action, President Obama increased fourfold the amount of protected marine space in waters under United States control, setting a major precedent for global ocean conservation. Using the U.S. president's authority under the Antiquities Act of 1906, he expanded to 200 nautical miles the seaward limits of Papahānaumokuākea Marine National Monument in Hawaiʻi and the Pacific Remote Islands Marine National Monument around the U.S. island possessions in the Central Pacific. In the Atlantic, President Obama created the Northeast Canyons and Seamounts Marine National Monument, the first marine monument in the U.S. exclusive economic zone (EEZ) in the Atlantic.
The marine protected areas of South Africa are in an area of coastline or ocean within the exclusive economic zone (EEZ) of the Republic of South Africa that is protected in terms of specific legislation for the benefit of the environment and the people who live in and use it. An MPA is a place where marine life can thrive under less pressure than unprotected areas. They are like underwater parks, and this healthy environment can benefit neighbouring areas.
Jacqueline (Jacqui) Evans is a marine conservationist from the Cook Islands. Her efforts to protect the marine environment surrounding the islands came to fruition in July 2017 when the government created the Marae Moana marine park. It provided for the sustainable management of 763,000 square miles of ocean territory, including 15 more highly protected exclusion zones covering 125,000. In recognition of her efforts, in April 2019 Evans was one of six environmentalists to be awarded the Goldman Environmental Prize.
Sustainable Development Goal 14 is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording is to "Conserve and sustainably use the oceans, seas and marine resources for sustainable development". The Goal has ten targets to be achieved by 2030. Progress towards each target is being measured with one indicator each.
