Arctic Ocean Temperature and Salinity Profiles from CTD Casts

NOAA NCEI Accession 9700135 contains temperature, salinity, sound velocity, and sigma-theta data collected from CTD casts aboard the Polar Sea. Measurements span nearly nine years, from August 1984 to April 1993. The data were submitted by Old Dominion University.

Use Cases

• Model Arctic Ocean water density stratification using sigma-theta and salinity profiles.
• Analyze temporal changes in temperature and salinity profiles over the 1984-1993 period.
• Calculate sound speed profiles for underwater acoustics research using sound velocity data.
• Validate regional oceanographic models with in-situ CTD cast data from the Polar Sea.

Strengths

• Data collection spans a significant time period of nearly nine years (1984-1993).
• Includes multiple derived physical parameters like sound velocity and sigma-theta.

Limitations

• Exact row count, column details, and sample size are unknown.
• Data temporal coverage ended in 1993, making it a historical snapshot.
