NOCN meaning in Academic & Science ?

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 was made up 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). Also, the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado is operated for NGDC by the University of Colorado through the Cooperative Institute for Research in Environmental Sciences (CIRES).

These discipline-oriented centers served as national repositories and dissemination facilities for global environmental data. The data archives amassed by the NODC and the other centers provide a record of Earth's changing environment, and support numerous research and operational applications and are still available through the NCEI. Working cooperatively, the centers provided data products and services to scientists, engineers, resource managers, policy makers, and other users in the United States and around the world.
