Oceanography Branch Hydrographic Database

The Oceanography group maintains and provides Conductivity/Temperature/Depth (CTD) instruments to all Center cruises for measuring water column profiles of temperature and salinity. Generally, over 1000 profiles are collected each year on the northeast continental shelf from Cape Hatteras to the Gulf of Maine. Profiles are collected at every station on the Center's bottom trawl surveys and at every station on the Center's Ecosystem Monitoring surveys. The database also contains historical hydrographic data from earlier programs, which used other methods to measure temperature and salinity.

To provide hydrographic measurements made by the NEFSC to support research, assessment, and management activities in the Northeast U.S. Shelf Ecosystem.

Data are publicly available. Questions should be directed to Paula Fratantoni (paula.fratantoni@noaa.gov)

NEFSC Data Access Procedure:

1. Formal request in writing usually to the data owner/contact or Center Director;

2. Requester is contacted by data owner to review and verify the request content and details for data delivery options.

3. If data is confidential then owner will determine if the data may be released to the requester;

4. If data can be released, the data is downloaded and packaged for delivery electronically; or the requester may be directed to where the data is available online.

NEFSC Data Access Constraint:

If data is stored on an internal NEFSC network, the requester may not have direct access to query the data unless they are also authorized for network access.
