Overview Quick Links:

The National Oceanographic Data Center (NODC) is 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 is located in Silver Spring, Maryland and is made up of five divisions (see the NODC organizational chart). The NODC also has field offices and Regional Science Officers collocated with major government or academic oceanographic laboratories in Stennis Space Center, MS; Miami, FL; La Jolla, CA; Seattle, WA; Austin, TX; Charleston, SC; Norfolk, VA; and Honolulu, HI.

NOAA also operates two other data centers: National Climatic Data Center (NCDC), Asheville, North Carolina and National Geophysical Data Center (NGDC), Boulder, Colorado. 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 serve 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. Working cooperatively, the centers provide data products and services to scientists, engineers, resource managers, policy makers, and other users in the United States and around the world.

NODC History

Established in 1961, the NODC was originally an interagency facility administered by the U.S. Naval Hydrographic (later Oceanographic) Office. The NODC was transferred to NOAA in 1970 when NOAA was created by Executive Order. In the words of its charter, the NODC serves to "acquire, process, preserve, and disseminate oceanographic data." Its primary mission is to ensure that global oceanographic data sets collected at great cost are maintained in a permanent archive that is easily accessible to the world science community and to other users.

Core Description

The National Oceanographic Data Center includes the National Coastal Data Development Center (NCDDC) and the NOAA Central Library, which are integrated to provide access to the world's most comprehensive sources of marine environmental data and information. NODC maintains and updates a national ocean archive with environmental data acquired from domestic and foreign activities and produces products and research from these data which help monitor global environmental changes. These data include physical, biological and chemical measurements derived from in situ oceanographic observations, satellite remote sensing of the oceans, and ocean model simulations. NODC personnel directly interact with Federal, state, academic, and industrial oceanographic activities, represent NOAA on various interagency domestic panels, committees and councils, and represent the United States in various international organizations, such as the International Oceanographic Data Exchange. The Data Center represents NOAA to the general public, government agencies, private institutions, foreign governments, and the private sector on matters involving oceanographic data.

NODC Data Holdings

The NODC manages the world's largest collection of publicly available oceanographic data. NODC holdings include in situ and remotely sensed physical, chemical, and biological oceanographic data from coastal and deep ocean areas. These were originally collected for a variety of operational and research missions by U.S. Federal agencies, including the Department of Defense (primarily the U.S. Navy); by State and local government agencies; by universities and research institutions; and private industry. NODC data holdings extend back over one hundred years, and the volume is expected to grow exponentially as new ocean observing systems are deployed. See the NODC Data Policy.

Through NODC archive and access services ocean data are being reused to answer questions about climate change, ocean phenomena, and management of coastal and marine resources, marine transportation, recreation, national security, and natural disasters. Another significant user community is Education, where these data and information products help teach each new generation of students about the oceans. Requests and downloads of oceanographic data and information have increased each year since the Center was established in 1961.

International Cooperation and Data Exchange

A significant percentage of the oceanographic data held by NODC is foreign. NODC acquires foreign data through direct bilateral exchanges with other countries, and through the facilities of the World Data Center for Oceanography, Silver Spring, which is collocated with and operated by NODC.

There are three World Data Centers for Oceanography:

  • World Data Center, Silver Spring, Maryland, United States
  • World Data Center, Moscow, Russia
  • World Data Center, Tianjin, People's Republic of China

They are part of the World Data Center System initiated in 1957 to provide a mechanism for data exchange, and they operate under guidelines issued by the International Council of Scientific Unions (ICSU).

Under NODC leadership, the Global Data Archeology and Rescue (GODAR) project has grown into a major international program sponsored by the Inter-governmental Oceanographic Commission. GODAR is a comprehensive effort to locate, rescue, quality control, and disseminate historical global ocean profile data for use by the climate and global change research community.

NOAA Library

The NODC also manages the NOAA Central Library in Silver Spring, MD, and regional libraries in Miami, FL, Seattle, WA, and College Park, MD. The combined libraries contain millions of volumes including books, journals, CD-ROMs, DVDs, audio, and video tapes.

Customer Services

Each year the NODC responds to thousands of requests for oceanographic data and information. Copies of specified data sets or data selected from the NODC's archive databases can be provided to users on various media types, or online. NODC data products are provided at prices that cover the cost of data selection and retrieval. However, data provided on the NODC public website is free of charge.
