Arctic Ocean CTD Measurements from the North Water Polynya Project, 1997-1999

1997 to 1999 data on temperature, salinity, conductivity, pressure, and transmissivity gathered by Conductivity-Temperature-Depth (CTD) instruments on Canadian Coast Guard Ships. The data were collected as part of the North Water Polynya project and are archived by NOAA's National Centers for Environmental Information (NCEI).

Use Cases

• Modeling Arctic water column structure based on temperature and salinity profiles.
• Analyzing polynya formation and persistence based on conductivity and temperature data.
• Studying oceanographic changes over time based on the 1997-1999 time series.
• Calibrating satellite-derived ocean data based on in-situ CTD measurements.

Strengths

• Data covers multiple key oceanographic variables: temperature, salinity, conductivity, pressure, and transmissivity.
• Measurements were taken over a defined multi-year period from 1997 to 1999.
• Data originates from a specific, documented scientific project (North Water Polynya).

Limitations

• Last updated 1999-10-05 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
