Since 1977, the Northeast Fisheries Science Center has been collecting hydrographic data on the northeast US continental shelf in support of efforts to understand how the components of this ecosystem influence the distribution, abundance, and productivity of living marine resources. Temperature and salinity profile data are collected on all Northeast Fisheries Science Center cruises, amounting to nearly 2000 profiles collected each year on the northeast continental shelf from Cape Hatteras to the Gulf of Maine. The data are collected aboard a variety of vessels, but most regularly from the Delaware II, HB Bigelow. The data are used to characterize baseline conditions on the shelf, as documented in annual summaries of regional average temperature and salinity, surface and bottom property distributions and their anomalies relative to a consistent reference (http://www.nefsc.noaa.gov/HydroAtlas.) The data have been and continue to be used to monitor the seasonal to inter-annual variability of water properties on the northeast US continental shelf.
These data are also accessible directly from the National Marine Fisheries Center http://www.nefsc.noaa.gov/epd/ocean/MainPage/ioos.html and from the National Oceanographic Data Center at http://www.nodc.noaa.gov/. Some of the data are also available from the Canadian Marine Environmental Data Service (MEDS) at http://www.meds-sdmm.dfo-mpo.gc.ca/isdm-gdsi/index-eng.html .
The null values of '999' were replaced with 'nd'.
A unique purpose code has been assigned to each survey, identifying the Northeast Fisheries Science Center program or larger national program to which those data are associated.

Occasionally, a cruise identifier (or opsid) contains more than one part. For example, ALB0301, actually consists of five (5) opsid's. This is because multiple hardware breakdowns during the cruise required that the ship return to port. Because these port visits spanned many days, different opsid's were assigned to each contiguous leg of the cruise.
