Arctic Ocean Winter CTD Data From Aircraft Sampling April 2003

Winter sampling collected data from 42 sites, comprising 49 CTD casts, in the eastern Arctic Ocean during April 2003. The data includes temperature, salinity, oxygen, nutrients, and isotopes from a series of 5 transect lines parallel to the SBI mooring line at 152W longitude. The dataset was created by NOAA NCEI as part of the Shelf-Basin Interactions Project.

Use Cases

• Analyzing vertical profiles of temperature and salinity across transect lines.
• Studying nutrient and oxygen distributions in the Arctic Ocean during winter.
• Comparing water column data from aircraft-sampled sites with concurrent mooring data at 152W.
• Investigating shelf-basin exchange processes using geospatial CTD cast data.

Strengths

• Contains data from 49 CTD casts across 42 distinct sampling sites.
• Covers a specific, focused wintertime sampling period from April 1-15, 2003.
• Spatially organized along 5 transect lines bracketing a key mooring line, enabling comparative analysis.

Limitations

• Specific column names and full data schema are unknown from all sources.
• Sources conflict on the last updated date, listing both 2003-04-15 and 2026-03-05.
• Total row count and file size are not provided by any platform.
