Marine Reserves
A marine reserve is a type of marine protected area (MPA). An MPA is a section of the ocean where a government has placed limits on human activity. A marine reserve is a marine protected area in which removing or destroying natural or cultural resources is prohibited, marine reserves may also be "no-take MPAs,” which strictly forbid all extractive activities, such as fishing and kelp harvesting. As of 2007 less than 1% of the world's oceans had been set aside in marine reserves. Benefits include increases in the diversity, density, biomass, body size and reproductive potential of fishery and other species within their boundaries. As of 2010, scientists had studied more than 150 marine reserves in at least 61 countries and monitored biological changes inside the reserves. The number of species in each study ranged from 1 to 250 and the reserves ranged in size from 0.006 to 800 square kilometers (0.002 to 310 square miles). In 2014, the World Parks Association adopted a target ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goat Island Marine Reserve
Cape Rodney-Okakari Point Marine Reserve is a protected area in the North Island of New Zealand. All fishing, and the removal or disturbing of marine life or materials, is forbidden within the reserve. The reserve covers an area of , extending from Cape Rodney to Okakari Point, extending 800m offshore. Te Hāwere-a-Maki / Goat Island lies within the reserve and Leigh, New Zealand, Leigh is the closest town. It was created in 1975 as the first marine reserve in New Zealand. Auckland University operates Leigh Marine Laboratory at the reserve. Laboratory scientists have scientific equipment around the reserve to study how marine ecosystems function. Geography The marine reserve has a variety of shores, including the rocky headland of Cape Rodney, the white sandy surf beach at Pakiri, and the sheltered mudflats and mangrove forests of Whangateau Harbour. There are also boulders, course sand, mudstone terraces, pebblestone rock and greywacke, providing a range of habitats for mari ...

Surface Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to ''channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is #Saturation excess overland flow, saturated by water to its full capacity, and the rain arrives #Infiltration excess overland flow, more quickly than the soil can absorb it. Surface runoff often occurs because wikt:impervious#Adjective, impervious areas (such as roofs and Road surface, pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of Soil erosion#Rainfall and runoff, soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. ...

Marine Protected Area
A marine protected area (MPA) is a protected area of the world's 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. MPAs can provide economic benefits by supporting the fishing industry through the revival of fish stocks, as well as job creation and other market benefits via ecotourism. The value of MPA to mobile species is unknown. There are a number of global examples of large marine conservation areas. The Papahānaumokuākea Mar ...

Marine Park
A marine park is a designated park consisting of an area of sea (or lake) set aside to achieve ecological sustainability, promote marine awareness and understanding, enable marine recreational activities, and provide benefits for Indigenous peoples and coastal communities. Most marine parks are managed by national governments, and organized like 'watery' national parks, whereas marine protected areas and marine reserves are often managed by a subnational entity or non-governmental organization, such as a conservation authority. The largest marine park used to be the Great Barrier Reef Marine Park in Australia, at 350,000 km² until 2010, when the United Kingdom announced the opening of the Chagos Marine Park or Chagos Archipelago. Although for many uses it is sufficient to designate the boundaries of the marine park and to inform commercial fishing boats and other maritime enterprises, some parks have gone to additional effort to make their wonders accessible to vi ...

Greenpeace Australia Pacific
Greenpeace Australia Pacific (GPAP) is the regional office of the global environmental organisation Greenpeace. Greenpeace Australia Pacific is one of Australia's largest environmental organisations. Origins and formation Greenpeace Australia had its roots in 1974 when Rolf Heimann skippered the 30-foot Tahiti ketch ''La Flor'' from Melbourne to Mururoa via New Zealand, to protest against French atmospheric nuclear testing, but arrived after the final nuclear test for the year. The regional office emerged when an activist group, the Whale and Dolphin Coalition, invited Canadian Bob Hunter, Greenpeace co-founder and its first president, and his wife Bobbi, Greenpeace's first treasurer, to Australia in 1977. Greenpeace's first direct action in Australia opened on 28 August 1977, at Albany, Western Australia against Australia's last whaling station. Over the next three weeks, activists used Zodiacs to place themselves between the harpoons of the three whale chaser ships and spe ...

Greenpeace
Greenpeace is an independent global campaigning network, founded in Canada in 1971 by a group of Environmental movement, environmental activists. Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its biodiversity, diversity" and focuses its campaigning on worldwide issues such as climate change, deforestation, overfishing, whaling, commercial whaling, genetic engineering, Anti-war movement, anti-war and anti-nuclear issues. It uses direct action, advocacy, research, and ecotage to achieve its goals. The network comprises 26 independent national/regional organisations in over 55 countries across Europe, the Americas, Africa, Asia, Australia and the Pacific, as well as a coordinating body, Greenpeace International, based in Amsterdam, Netherlands. The global network does not accept funding from governments, corporations, or political parties, relying on three million individual supporters and foundation grants.

Plankton
Plankton are the diverse collection of organisms that drift in Hydrosphere, water (or atmosphere, air) but are unable to actively propel themselves against ocean current, currents (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and baleen whales. Marine plankton include bacteria, archaea, algae, protozoa, microscopic fungi, and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. fresh water, Freshwater plankton are similar to marine plankton, but are found in lakes and rivers. Mostly, plankton just drift where currents take them, though some, like jellyfish, swim slowly but not fast enough to generally overcome the influence of currents. Although plankton are usually thought of as inhabiting water, there are also airborne versions that live part of their lives drifting in the at ...

Pelagic
The pelagic zone consists of the water column of the open ocean and can be further divided into regions by depth. The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. In a manner analogous to stratification in the Earth's atmosphere, the water column can be divided vertically into up to five different layers (illustrated in the diagram), with the number of layers depending on the depth of the water. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind st ...
