Bering and Chukchi Seas Water Chemistry and CTD Measurements from July 2013

Water samples and CTD data were collected aboard the CCGS Sir Wilfrid Laurier from 2013 07 14 to 2013 07 23 in the Bering and Chukchi Seas. The dataset includes measurements for temperature, salinity, dissolved oxygen, chlorophyll a, nutrients, and stable oxygen isotopes. Data were aggregated by NOAA NCEI from the Arctic Data Center and are provided in XLSX and CSV formats.

Use Cases

• Modeling oceanographic conditions based on CTD-measured temperature, salinity, and pressure profiles.
• Analyzing nutrient cycles based on phosphate, silica, nitrite+nitrate, and ammonium concentrations.
• Studying water mass origins and mixing using stable oxygen isotope (delta-O18) values.
• Investigating phytoplankton biomass based on chlorophyll a concentration measurements.

Strengths

• Data includes multiple related oceanographic parameters (e.g., CTD, nutrients, isotopes) from a single cruise.
• Measurements are georeferenced with latitude, longitude, and station depth.
• Temporal coverage is precisely defined from 2013-07-14 to 2013-07-23.

Limitations

• Last updated 2013-07-23 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
