The National Oceanographic Data Center (NODC) was one of the national environmental data centers operated by the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Department of Commerce. The main NODC facility was located in Silver Spring, Maryland, and consisted of five divisions. The NODC also had field offices collocated with major government or academic oceanographic laboratories in Stennis Space Center, MS; Miami, FL; La Jolla, San Diego, California; Seattle, WA; Austin, Texas; Charleston, South Carolina; Norfolk, Virginia; and Honolulu, Hawaii. In 2015, NODC was merged with the National Climatic Data Center and the National Geophysical Data Center into the National Centers for Environmental Information (NCEI).
NOAA also operated two other data centers: National Climatic Data Center (NCDC), Asheville, North Carolina and National Geophysical Data Center (NGDC), Boulder, Colorado. In 2015, the three merged to form the National Centers for Environmental Information (NCEI). The National Snow and Ice Data Center (NSIDC) in Boulder, Colorado, is also operated for NGDC by the University of Colorado through the Cooperative Institute for Research in Environmental Sciences (CIRES).
