| | The definition of a protected area, as adopted by IUCN, is: an area of land and/or sea especially dedicated to the protection and maintenance of biological diversity, and of natural and associated cultural resources, and managed through legal or other effective means. Although all protected areas meet the general purposes contained in this definition, in practice the precise purposes for which protected areas are managed differ greatly. | | | | The benefits of establishing marine protected areas (MPAs) are well known, particularly for coral reefs. A reduction in fishing pressure, ideally through the complete closure of selected areas to all types of fishing, typically maintains more numerous and diverse populations of previously targeted species, leads to the reappearance of species absent from fishing grounds and substantially increases the biomass of large predatory species. There can also be positive effects on coral reef habitat with increased coral cover and structural complexity. | | | | The World Database on Protected Areas (WDPA) is a global database of protected areas maintained as a collaboration the IUCN World Commission on Protected Areas (WCPA) and the UNEP-World Conservation Monitoring Centre. This is the only comprehensive global list of protected areas, and contains links to descriptive data describing important sites ('site sheets'), and GIS-data showing the distribution of sites, including mapped boundaries for a large number of locations. Information of more than 4000 MPAs is included in the World Database on Protected Areas, and site sheets have been completed for approximately 20% of these. | | | | |

| | | Title | Alaska Fisheries Science Center databases
( WEBSITE )
| | Description | Databases on fishery, oceanography, marine mammal, and environmental research compiled by Alaska Center scientists are used to develop policies and strategies for fisheries management within the U.S. Exclusive Economic Zone, to monitor and manage the health of the region's marine mammal populations, and to assess the impacts of chemical contaminants and physical alterations on select organisms and marine habitats. The data, some dating back nearly 100 years, are obtained from boat surveys, aerial surveys, land counts, stream and beach surveys, and other miscellaneous sources. These databases are available for downloading from the AFSC website or from database managers at the Alaska Center. | | Keywords |  ALASKA; DATABASE; FISHERIES; OCEANOGRAPHY; MARINE MAMMALS; ENVIRONMENT; SCIENCE | | Geography Keywords | ALASKA; USA; NORTH PACIFIC OCEAN | | Content Language(s) | English | | Web Address (URL) | http://www.afsc.noaa.gov/databases.htm | |
