Ross Sea CTD Measurements from the AnSlope Program (2004)

2004 data from the AnSlope program in the Ross Sea, collected from the Nathaniel B. Palmer research vessel. The dataset contains oceanographic measurements including temperature, salinity, dissolved oxygen, and pressure to study dense water transfer and poleward flow. It is managed by NOAA NCEI and appears on multiple government data platforms.

Use Cases

• Analyzing vertical profiles of temperature and salinity to identify shelf-modified dense water masses.
• Studying the relationship between dissolved oxygen levels and water mass age or origin.
• Investigating pressure data to understand the dynamics of compensatory poleward flows from the oceanic regime.
• Calibrating or validating regional ocean circulation models for the Ross Sea.

Strengths

• Data originates from a focused scientific program (AnSlope) with a clear research goal.
• Cross-platform presence on NASA EarthData and Data.gov indicates recognized importance and curation.
• Includes key physical oceanography parameters (temperature, salinity, dissolved oxygen, pressure).

Limitations

• Specific column names, row counts, and file size are not provided by any source.
• Conflicting last updated dates exist: one source shows 2004-04-02, while others show 2026-03-01, suggesting a metadata inconsistency.
• The license and detailed author information are unknown.
