NOAA's National Ocean Service
The National Ocean Service (NOS) is a US government agency working to observe, understand and manage the coastal and marine environment of the United States. The site includes links to news and events, publications and products (some in PDF format), with links to other US government bodies, geodetic data, and environmental programs and education. The site also includes a search engine and links to NOS sites such as the Office of Response and Restoration, responding to oil and hazardous materials spills, and the Office of Ocean and Coastal Resource Management (OCRM).
