Arctic Ocean CTD Profiles from Helicopter Surveys

Arctic Ocean and Beaufort Sea high-resolution CTD/STD data were collected via helicopter from October 1986 to April 1987. The dataset provides nearly continuous vertical profiles of temperature, salinity, and other parameters, processed by the NODC to its F022 standard format. It was submitted by the NOAA National Centers for Environmental Information.

Use Cases

• Analyzing vertical structure of temperature and salinity in the Arctic Ocean using depth or pressure level data.
• Studying seasonal hydrographic changes from fall to spring using the time-stamped station data.
• Calculating water density (sigma-t) for oceanographic models from the reported conductivity, temperature, and depth measurements.
• Correlating oceanographic casts with reported environmental conditions like meteorological data.

Strengths

• Data provides high-resolution profiles with sampling intervals as fine as 1 meter.
• Coverage spans a full seasonal cycle from October to April in the Arctic.
• Data is processed to a recognized standard format (NODC F022) ensuring consistency.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• One source title mentions the Chukchi Sea and parameters like nitrate, which conflicts with the primary description focusing on the Beaufort Sea and core CTD parameters.
