High-Resolution CTD/STD Ocean Profiles from R/V Gyre 1981-1983

Two years of high-resolution oceanographic profiles collected by the R/V Gyre in the Bay of Fundy and North Atlantic Ocean from June 1981 to June 1983. The National Oceanographic Data Center processed the data to its standard F022 format, which contains nearly continuous vertical measurements. This dataset provides detailed station-based observations from a specific research vessel.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass distribution and stratification.
• Calculating density (sigma-t) from measured parameters to investigate ocean circulation and stability.
• Correlating station data (position, date, time) with meteorological conditions to understand air-sea interactions.
• Using high-resolution depth/pressure interval data to calibrate or validate regional oceanographic models.

Strengths

• Data provides high-resolution vertical profiles, with measurements reported at depth intervals as fine as 1 meter.
• Coverage spans a two-year time range from 1981-06-01 to 1983-06-15 for temporal analysis.
• Processed and formatted to a recognized standard (NODC F022), ensuring structured consistency.

Limitations

• Exact row count, column names, and dataset size are unknown from available sources.
• Sources conflict on the last update date: one lists 2026-03 05 (metadata update), while another lists 1983-06-15 (data collection end).
• License information and specific author details are not provided.
