Reports on activities: World Data Center for Oceanography, Silver Spring
World Data Center (WDC) for Oceanography is one component of a global network of discipline subcenters that facilitate international exchange of scientific data. Originally established during the International Geophysical Year of 1957-58, the World Data Center System functions under the guidance of the International Council of Scientific Unions (ICSU). WDC for Oceanography, Silver Spring, is collocated with, and operated by the U.S. National Oceanographic Data Center (NODC). In accordance with principles set forth by ICSU, WDC for Oceanography acquires, catalogues, and archives data, publications, and data inventory forms and makes them available to requesters in the international scientific community. To improve user access, the WDC provides copies of data it receives to its counterparts, World Data Center for Oceanography (Obninsk, Russia) and World Data Center for Oceanography (Tianjin, China). However, for certain types of data, the exchange of inventories of available data in a WDC subcenter may be considered acceptable in lieu of the transfer of the actual data sets. Oceanographic data contributed to the WDC become automatically available to scientific investigators in any country. Thus, there is no restrictions or limitations placed on data exchanged through the WDC system.
