The National Ocean Service provides a comprehensive geospatial metadata inventory for the public to search and find NOS geospatial data resources. Since 2007, this NOS metadata inventory was made available via the NOS Data Explorer geoportal website.
Since then, NOAA has embarked on a large-scale effort to centralize such resources. In compliance with the President's Open Data Policy, the NOS geospatial metadata inventory will now be served via the NOAA Data Catalog. The NOAA Data Catalog is now our agency level metadata portal providing metadata from NOAA to Data.gov.
The NOS Data Explorer website will be officially decommissioned on Jan. 31, 2015. Please notify any of your colleagues or user communities and bookmark the new (prototype) NOAA Data Catalog site here: http://data.noaa.gov/
