Surface Ocean Carbon Dioxide Measurements from Cruise Ship Allure of the Seas in 2019

Sea surface underway measurements of partial pressure of carbon dioxide, temperature, salinity, and barometric pressure collected during the C/S Allure of the Seas cruise lines. The dataset was gathered by the NOAA Atlantic Oceanographic and Meteorological Laboratory's Ocean Carbon Group using an autonomous instrument installed on the ship. Observations cover the Caribbean Sea, Gulf of Mexico, and North Atlantic Ocean from January 13, 2019, to January 5, 2020.

Use Cases

• Analyze temporal trends in sea surface pCO2 levels across the Caribbean Sea and Gulf of Mexico.
• Correlate partial pressure of carbon dioxide with concurrent measurements of sea surface temperature and salinity.
• Investigate spatial gradients of barometric pressure and its relationship with oceanic carbon measurements.
• Validate regional ocean carbon cycle models using in-situ pCO2 data from a ship-of-opportunity platform.

Strengths

• Continuous underway measurements from a fixed vessel platform over a nearly full year.
• Data covers multiple major ocean basins: Caribbean Sea, Gulf of Mexico, and North Atlantic Ocean.

Limitations

• Specific sample size, row count, and measurement frequency are unknown.
• Limited to surface water and near-surface air measurements, lacking depth profiles.
