Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected f

NODC Accession 0117699 contains surface underway data collected by NOAA Ship RONALD H. BROWN in the North and South Atlantic Ocean between July and October 2013. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure. These data were collected by Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory as part of the VOS_A16N_2013 and VOS_A16N_2013_Transit data sets for the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Modeling ocean carbon uptake based on air-sea difference in carbon dioxide partial pressure.
• Analyzing sea surface temperature and salinity correlations with carbon dioxide levels.
• Studying temporal trends in atmospheric and oceanic carbon dioxide during a specific 2013 transect.
• Calibrating satellite-derived carbon flux estimates with in-situ surface underway measurements.

Strengths

• Data collection spans a specific 77-day period from 2013-07-18 to 2013-10-02.
• Includes concurrent measurements of multiple related variables: carbon dioxide in air and water, salinity, temperature, and barometric pressure.
• Data is associated with a named research program: the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2013-10-02; freshness should be verified for contemporary applications.
