The National
Oceanographic Data Center (NODC) manages the acquisition, ingest processing,
quality control and long-term preservation of oceanographic data. The
data are scanned for viruses, and cryptographic checksums are generated
and stored with the original data files so data integrity can be monitored
and verified over extended time periods and across generations of storage
technologies. A copy of the data is written to near-line mass storage
and a copy is written to removable media for off-site storage.The NODC
archive holdings include all the data acquired in its original form,
as well as project and product files of data extractions. (...more
about what happens to data submitted to NODC).
Every
data acquisition is assigned a unique identification number called an
accession number, to be used as a lifetime reference to that data. Each
unique data set will contain a metadata description to aid in search
and discovery processes. A copy of all original NODC digital data holdings
is maintained in an online storage system for unattended access by our
users.
Direct access to the NODC archive of originators' data can be obtained
by using the NODC Ocean Archive System.
You
can also submit your oceanographic
data files to NODC's archives, or find ocean data that you already submitted.
The National
Oceanographic Data Center holds global physical, chemical, and biological
oceanographic data sets that are being used by researchers world-wide.
Specifically NODC's Ocean Climate Laboratory is
investigating interannual-to-decadal ocean climate variability using
historical oceanographic data, and building scientifically, quality-controlled
global oceanographic databases in their products known as the World
Ocean Atlas and World Ocean Database.

NODC has
several ocean-data Web applications that can be accessed through the
Internet. Some of these observing systems contain near-realtime
data, while others are long-term archives for a certain project. Here
is a list of observing systems that NODC provides archive services for:
- Global Argo Data Repository - latest data
- Coastal Buoy Data
- Coastal Water Temperature Guide (CWTG)
- Global Temperature-Salinity Profile
Program (GTSPP)
- Joint Archive
for Sea Level (JASL)*
- Joint Archive for Shipboard ADCP (JASADCP)*- [NODC's ADCP page]
- Ocean Time Series Data Base (TSDB)
- Satellite Oceanography
- Shipboard Sensor Database (SSD)
The National Coastal Data Development Center (a division of NODC) provides data management and data discovery mechanisms for several ocean and coastal observational systems. You may also want to visit our Environmental Themes page to see how NODC relates to these important topics.
