Surface Ocean CO2 and Temperature Measurements from Galapagos Cruise Ship in 2020

Surface underway observations of partial pressure of carbon dioxide, temperature, salinity, and barometric pressure were collected during a Celebrity Flora cruise in the Pacific Ocean. The dataset covers a two-week period from January 12 to January 26, 2020. It was contributed by NOAA's National Centers for Environmental Information (NCEI) from an instrument installed on a cruise ship designed for Galapagos tours.

Use Cases

• Analyze the relationship between partial pressure of carbon dioxide (pCO2) and sea surface temperature across the cruise track.
• Investigate salinity gradients and their correlation with barometric pressure readings in the Galapagos region.
• Model short-term variability in surface ocean carbon chemistry using the high-frequency underway time-series data.
• Validate satellite-derived sea surface temperature or salinity products with in-situ measurements from the cruise.

Strengths

• Data collection spans a specific two-week period from 2020-01-12 to 2020-01-26.
• Includes multiple concurrent variables: pCO2, temperature, salinity, and barometric pressure.
• Originates from a dedicated CO2 instrument installed on a vessel conducting repeated loops in the study area.

Limitations

• The exact number of data rows and spatial resolution are unknown.
• Temporal coverage is limited to a short, 14-day period in January 2020.
• Geographic coverage for this specific accession is focused on the Pacific Ocean leg, though the instrument operated in other regions.
