Philippine Sea Surface Carbon Dioxide and Salinity Measurements from ROGER REVELLE, 2016

Philippine Sea surface underway data from the R/V Roger Revelle cruise 33RR20160519, collected from May 19 to May 28, 2016. The dataset contains measurements of carbon dioxide partial pressure in air and water, sea surface temperature, salinity, and barometric pressure, collected using a CO2 gas analyzer. It is part of the VOS_33RR20160519_RR1606 dataset and was contributed by NOAA's Atlantic Oceanographic and Meteorological Laboratory.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Analyzing ocean acidification drivers using in-situ pCO2 and salinity measurements.
• Validating satellite-derived sea surface temperature and salinity products.
• Studying short-term variability in surface ocean carbon chemistry during a research cruise.

Strengths

• Data has a precise temporal coverage from 2016-05-19 to 2016-05-28.
• Includes direct, instrument-based measurements of carbon dioxide partial pressure in both air and sea water.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating curation and importance.

Limitations

• Column names and row counts are not provided in any source, limiting immediate usability.
• Conflicting 'last updated' dates (2026-03-05 vs. 2016-05 28) create uncertainty about metadata maintenance.
• License information is absent, which may restrict certain uses.
