North Atlantic Ocean data from 79 Underway CTD casts collected during the EN492 cruise in April-May 2011. The Graduate School of Oceanography at the University of Rhode Island processed measurements of temperature, conductivity, and pressure to compute salinity, potential temperature, and potential density. Data are averaged into 1 decibar bins.
Use Cases
- Analyzing vertical profiles of potential temperature and salinity across 79 casts to study water mass distribution north of Flemish Cap.
- Modeling the relationship between measured temperature, pressure, and derived potential density to understand stratification.
- Investigating instrument descent rate effects by applying corrections for viscous heating and conductivity cell thermal mass to the raw temperature and conductivity signals.
- Creating time-series of oceanographic conditions using 1 dbar binned data for the April-May 2011 period.
Strengths
- 79 distinct Underway CTD casts provide multiple spatial samples.
- High-frequency raw measurements at 16 Hz, processed and binned to 1 dbar resolution.
Limitations
- Dataset is limited to a single cruise over two months (April-May 2011), offering a temporal snapshot.
- Geographic scope is focused solely on the region north of Flemish Cap in the North Atlantic.
