Southern Ocean Atlas: Physical and Chemical Water Properties

Oceanographic station data provides a uniform array for studying the physical and chemical properties of the Southern Ocean water column. The dataset was compiled by the Lamont-Doherty Geophysical Observatory of Columbia University and the NOAA National Centers for Environmental Information. Data collection spans from 1947 to 1980, with the atlas format including grid point data files and objective contouring graphics.

Use Cases

• Numerical analysis of water column properties using derived grid point data.
• Objective contouring and graphical representation of weighted oceanographic variables.
• Studies of deep ocean physical and chemical property changes over a multi-decadal period.
• Calibration and validation of oceanographic models for the Southern Ocean region.

Strengths

• Data collection spans a 34-year time range from 1947 to 1980.
• Designed to provide a high-quality uniform array of deep-reaching station data.
• Dataset is maintained by authoritative organizations NOAA NCEI and Columbia University.

Limitations

• Specific column names, row counts, and file sizes are not documented in the provided sources.
• There is a conflict in last updated dates: Data.gov shows 2026 (likely a placeholder), while NASA Earthdata shows 1980.
• The original data format and specific measured variables are not detailed.
