MIKHAIL SOMOV: High-Resolution Ocean CTD/STD Profiles

NODC Accession 8300153 contains high-resolution CTD/STD data from the research vessel MIKHAIL SOMOV in the South Atlantic and Southern Oceans. The dataset, processed to the NODC F022 standard, provides near-continuous vertical profiles of temperature, salinity, density, and other parameters at depth intervals as fine as 1 meter. It includes station metadata, position, date, time, and may contain environmental data from the time of each cast.

Use Cases

• Analyzing vertical thermohaline structure based on high-resolution temperature and salinity profiles.
• Studying water mass properties and circulation patterns in the South Atlantic and Southern Oceans using station data.
• Calibrating ocean models with in-situ conductivity-temperature-depth measurements.
• Investigating relationships between surface meteorological conditions and subsurface ocean properties using reported environmental data.

Strengths

• Data is processed to a recognized standard format (NODC F022), ensuring structured consistency.
• Provides high-resolution profiles with depth intervals potentially as fine as 1 meter.
• Covers a specific, documented cruise period from 1981-10-21 to 1981-11-13.

Limitations

• Key metadata is missing, including column names, row count, file size, and license.
• The dataset's last update date (2026-04-01) conflicts with the collection end date (1981-11-13), suggesting metadata management rather than data revision.
• Documentation gaps exist regarding specific instruments used and the exact parameters measured beyond the core F022 specification.
