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 the NODC Archive).
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.
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.

Data page.
NODC has
several ocean-data Web applications that can be accessed through the
Internet, either directly through the NODC home page
or via pointers served by the NNDC
Server system. Some of these observing systems contain near-realtime
data, while others are long-term archives for a certain project. Here
is a list of NODC's observing systems:
- Acoustic Doppler Current Profiler Data
(ADCP)
- Argo Profiling Float data
- Coastal Buoy Data
- Coastal Water Temperature Guide (CWTG)
- Global Temperature-Salinity Profile
Program (GTSPP)
- Joint Archive
for Sea Level (JASL)
[JASL data is located at the
Univ. of Hawaii, you will be leaving the federal government webspace]
- Ocean Time Series Data Base (TSDB)
- Satellite Data from the Satellite Oceanography Group
at NODC (SOG)
