Ross Sea CTD Profiles from Deep Freeze Expeditions

1976 to 1985 data from CTD and STD instrument casts aboard the USCGC POLAR SEA and other vessels in the Ross Sea. The dataset provides high-resolution vertical profiles of temperature, salinity, density, and other chemical parameters. It was submitted by the Lamont-Doherty Geological Observatory under the Deep Freeze project and processed by NODC into the standard F022 format.

Use Cases

• Analyzing vertical structure of water temperature and salinity in the Ross Sea.
• Calculating density (sigma-t) from temperature and salinity profiles to study ocean stratification.
• Investigating dissolved oxygen or transmissivity levels at specified depth or pressure intervals.
• Correlating oceanographic conditions with recorded meteorological and sea surface data from each station.

Strengths

• High-resolution profiles with data potentially reported at depth intervals as fine as 1 meter.
• Covers a multi-year time range from December 1976 to February 1985.
• Processed to a documented standard format (NODC F022), ensuring consistent structure.

Limitations

• Exact row count, column names, and dataset size are unknown across all sources.
• Conflicting last update dates: one source lists 1985-02-06, while others list 2026-03 06.
• License information is not provided.
