High-Resolution CTD and Meteorological Profiles from NW Atlantic

270 high-resolution conductivity, temperature, and depth records were collected from 9 oceanographic casts during a 1994 NOAA cruise. The National Ocean Service submitted the data, which includes profiles of salinity, density, and dissolved oxygen at fine depth intervals. Measurements span a one-month period from May 20 to June 23, 1994.

Use Cases

• Model vertical salinity gradients using conductivity and temperature profiles from the 9 casts.
• Analyze correlations between reported meteorological conditions at the sea surface and subsurface density (sigma-t) measurements.
• Validate oceanographic interpolation methods using data reported at 1-meter depth intervals.
• Study short-term oceanographic variability by examining time-series data from the month-long cruise.

Strengths

• High-resolution vertical profiles with potential 1-meter sampling intervals.
• 9 distinct casts provide spatial coverage across the NW Atlantic study area.
• Includes derived parameters like computed density (sigma-t) alongside raw sensor data.

Limitations

• Limited temporal scope covering only 34 days in 1994.
• Small sample size of 270 total records from 9 casts.
• Potential for instrument-specific bias or calibration drift as data is from a single cruise.
