NOAA Miller Freeman CTD/STD Ocean Profiles: Bering Sea and Gulf of Alaska

High-resolution CTD/STD data from NOAA Ship Miller Freeman provides near-continuous vertical profiles of oceanographic parameters. The dataset covers the Bering Sea and Gulf of Alaska during a cruise from January to April 1980. Data records likely contain temperature, salinity, density, and possibly dissolved oxygen or transmissivity at depth intervals as fine as one meter.

Use Cases

• Analyzing vertical water column structure based on high-resolution temperature and salinity profiles.
• Studying regional oceanographic conditions in the Bering Sea and Gulf of Alaska using cruise station data.
• Calculating derived parameters like density (sigma-t) from the reported conductivity, temperature, and depth measurements.
• Correlating subsurface ocean data with reported surface meteorological conditions from the time of the cast.

Strengths

• High vertical resolution, with data potentially reported at depth intervals as fine as 1 meter.
• Data processed to a standardized, well-documented format (NODC F022).
• Cross-platform presence on Data.gov and NASA Earthdata suggests recognized importance.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable from all sources.
• The dataset is historical, with data collection ending in April 1980.
• Conflicting 'last updated' metadata: one source shows 2026 (likely a repository refresh), while another shows the original 1980 collection date.
