NCEI Accession 0167322: Arctic Ocean Carbon and Hydrographic Measurements

NCEI Accession 0167322 contains surface underway and discrete bottle data from the CCGS Amundsen research vessel in the Canadian Arctic. The dataset includes measurements of partial pressure of carbon dioxide (pCO2), dissolved inorganic carbon, total alkalinity, stable oxygen isotopes, sea surface temperature, and salinity. Data were collected by a consortium of Canadian universities during ArcticNet cruises from August 2013 to August 2014 in Baffin Bay, Nares Strait, and Lancaster Sound.

Use Cases

• Calculating ocean carbon uptake based on underway pCO2 measurements.
• Assessing ocean acidification trends using discrete bottle alkalinity and dissolved inorganic carbon data.
• Calibrating satellite-derived sea surface salinity with in-situ CTD measurements.
• Studying water mass mixing and freshwater sources via stable oxygen isotope analysis.
• Validating regional Arctic oceanographic models with continuous surface underway data.

Strengths

• Data collection spans a full annual cycle from August 2013 to August 2014.
• Combines high-frequency underway measurements with discrete bottle samples for validation.
• Involves multiple principal investigators from major Canadian research institutions.

Limitations

• Specific column names and row counts are not provided in any source.
• License information is absent from all platform descriptions.
• The dataset's internal structure and file formats beyond HTML are unclear.
