NOAA Ship Ronald H. Brown 2003 Underway Carbon Dioxide and Ocean Data

Surface underway measurements of carbon dioxide partial pressure, water temperature, and salinity collected during nine NOAA Ship Ronald H. Brown cruises in 2003. The dataset includes fugacity of carbon dioxide in water and atmosphere, wind direction, and speed, collected by Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory. Data collection occurred from February to November 2003 across the Pacific Ocean, Atlantic Ocean, Caribbean Sea, and Gulf of Mexico.

Use Cases

• Modeling ocean carbon uptake based on partial pressure of carbon dioxide in water and atmosphere.
• Analyzing sea surface temperature and salinity relationships across ocean basins.
• Studying wind patterns and their influence on air-sea gas exchange.
• Calibrating and validating carbon dioxide measurement instruments like equilibrators and gas analyzers.

Strengths

• Data spans nine distinct cruises (RB200301-RB200309) over a 9-month period in 2003.
• Includes simultaneous measurements of carbon dioxide in both water and atmosphere, enabling flux calculations.
• Covers a wide geographic area including the Pacific Ocean, Atlantic Ocean, Caribbean Sea, and Gulf of Mexico.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect temporal bias inherent to the specific 2003 collection period.
