NW Atlantic Ocean CTD Temperature and Salinity Profiles from 1978

NOAA_NCEI provides temperature and salinity profile data collected from STD/CTD casts aboard the R/V GYRE and other vessels in the Northwest Atlantic Ocean. The dataset, submitted by the University of Washington for the IDOE/POLYMODE project, contains high-resolution vertical profiles processed to the NODC F022 standard format. Measurements were taken during a specific cruise period from May 20 to July 14, 1978.

Use Cases

• Analyzing vertical temperature and salinity gradients in the NW Atlantic Ocean using depth or pressure level data.
• Calculating derived oceanographic parameters like density (sigma-t) from the provided temperature and salinity measurements.
• Studying spatial and temporal variability of water masses during the 1978 POLYMODE experiment cruise period.
• Correlating subsurface ocean conditions with reported surface meteorological and sea state data from the cast records.

Strengths

• Data is structured according to the documented NODC F022 standard format, ensuring a known schema.
• Profiles offer high vertical resolution, with measurements potentially reported at intervals as fine as 1 meter.
• Dataset includes ancillary station metadata such as position, date, time, cruise, and instrument information.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source platform.
• Conflicting last updated dates exist between sources (1978-07-14 vs. 2026-03-05), creating uncertainty about metadata maintenance.
