摘要

Hydrographic survey metadata development at NOAA's office of Coast Survey has evolved from a localized operation to an open and integrated database in cooperation with NOAA's National Geophysical Data Center (NGDC). Coast Survey, in partnership with NGDC, is recovering bottom sample data to help researchers and planners with marine habitat study, geologic research, coastal zone management and analysis of environmental change. The samples may help them understand the impact of benthic habitat on fisheries and other biological communities, for instance, how sediment texture potentially influences distribution and population size of ground fish. The samples also identify dredged material for beach replenishment, help estimate the impacts of events related to slope activity and are useful in locating offshore mineral resources. Coastal managers can use the sample data to determine sites for seabed communication cables, drilling platforms and other structures as well as proposed sites for offshore waste disposal. The samples also aid in environmental prediction as surrogates of past climate change, ground truth for remotely sensed data, and identification of the extent, nature and transport of pollutants.
