85 CTD profiles report ocean pressure, temperature, and salinity data from the Bellingshausen Sea. The data were collected during the austral spring of 2007 by the University of Colorado Boulder and Lamont-Doherty Earth Observatory aboard the R/V Nathaniel B. Palmer. Observations focus on the continental shelf slope to a nominal depth of 500 meters, with some full-depth profiles.
Use Cases
- Analyze temperature-salinity relationships across 85 profiles to study water mass structure in the Bellingshausen Sea.
- Model vertical stratification using pressure (depth), temperature, and salinity columns from shelf slope transects.
- Investigate seasonal hydrographic conditions during the 2007 austral spring using the time-stamped profile data.
- Correlate CTD profile data with concurrent underway mapping of sea surface properties and meteorological variables.
Strengths
- 85 distinct CTD profiles provide multiple sampling points.
- Data includes measurements to a nominal depth of 500m with some full-depth profiles for context.
- Temporal coverage is precisely defined for the austral spring of 2007.
Limitations
- Sample size is limited to 85 profiles from a single cruise.
- Geographic coverage is restricted to the Bellingshausen Sea cruise track.
- Data is from 2007 and may not represent current ocean conditions.
