Arctic Ocean CTD/STD Profiles from USCGC NORTHWIND

High-resolution conductivity-temperature-depth and salinity-temperature-depth data collected by the USCGC NORTHWIND in the Arctic Ocean, Bering Sea, and Greenland Sea. The dataset was processed by the National Oceanographic Data Center to its F022 standard format and spans a five-year period from 1980 to 1985. It provides nearly continuous vertical profiles of key oceanographic parameters.

Use Cases

• Analyzing vertical profiles of temperature and salinity to study water mass distribution in Arctic seas.
• Calculating density (sigma-t) from measured parameters to understand ocean stratification and circulation.
• Correlating station data (position, date, time) with environmental conditions like meteorological observations.
• Investigating temporal changes in oceanographic conditions across the 1980-1985 sampling period.

Strengths

• Data provides high-resolution profiles with depth intervals as fine as 1 meter.
• Coverage spans multiple critical Arctic and sub-Arctic regions over a five-year time range (1980-1985).
• Processed to a standardized NODC format (F022), ensuring consistency for analysis.

Limitations

• Specific row counts, column names, and dataset size are not provided by any source.
• Sources disagree on the 'last updated' metadata, with dates ranging from 1985-09 26 to 2026-03-05.
• The presence of additional parameters like dissolved oxygen or transmissivity is noted as 'possibly' available, not guaranteed.
