Atlantic Ocean Surface CO2 and Temperature Measurements from NOAA Ship Ronald H. Brown

Over 13 months of surface underway observations captured air-sea carbon dioxide exchange, salinity, and sea surface temperature in the Atlantic Ocean. The dataset was collected by the NOAA Ship Ronald H. Brown as part of the Ship of Opportunity Program. Measurements span from January 8, 2013, to February 4, 2014.

Use Cases

• Modeling air-sea pCO2 difference using concurrent measurements of atmospheric pCO2 and water pCO2.
• Analyzing the relationship between sea surface temperature and pCO2 in water across the Atlantic transect.
• Correlating salinity variations with partial pressure of carbon dioxide in surface waters.
• Validating satellite-derived sea surface temperature products with in-situ underway measurements.
• Investigating seasonal trends in barometric pressure and its potential influence on CO2 gas analyzer readings.

Strengths

• Data collection spanned over 13 consecutive months, providing temporal continuity.
• Includes multiple directly measured chemical and physical variables like pCO2, temperature, and salinity.
• Collected via dedicated instruments (CO2 gas analyzer, equilibrator) on a NOAA research vessel.

Limitations

• The exact spatial resolution and total number of data points (rows) are unknown.
• Limited to a single vessel's track in the Atlantic Ocean, not a global or gridded product.
• Data is over a decade old, limiting analysis of recent ocean carbon cycle changes.
