R/V G.O. Sars 2016 Underway Carbon Dioxide Measurements

NCEI Accession 0169195 contains underway surface measurements of carbon dioxide partial pressure from the R/V G.O. Sars across the North Atlantic, Norwegian, and North Seas. Data from 2016-02-20 to 2016-11-30 include atmospheric and aquatic pCO2, sea surface temperature, and salinity, collected using a CO2 gas analyzer and equilibrator. These measurements support the SOOP_GO_Sars_20016 dataset for studying ocean-atmosphere carbon exchange.

Use Cases

• Modeling ocean-atmosphere carbon dioxide flux based on partial pressure measurements.
• Analyzing seasonal variability of surface water pCO2 across multiple sea basins.
• Calibrating satellite-derived sea surface temperature and salinity products with in-situ data.
• Studying the relationship between barometric pressure and atmospheric pCO2 over the ocean.

Strengths

• Covers a nine-month time range from February to November 2016, capturing seasonal variation.
• Includes simultaneous measurements of both atmospheric and aquatic carbon dioxide partial pressure.
• Data collected using specific, named instruments: a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable from all sources.
• Sources disagree on the last updated date, with one showing 2016-11-30 and another showing a future date of 2026-03-05.
• The dataset's license and detailed provenance for the specific data files are not provided.
