VOS_OLIPAC_1994: Surface Ocean CO2 and Physical Variables in the Pacific

Surface underway measurements from the R/V L'ATALANTE cruise 35A319941105 collected in the North and South Pacific Ocean between November 5 and 29, 1994. The dataset includes the partial pressure (fugacity) of carbon dioxide in seawater, salinity, sea surface temperature, and barometric pressure, recorded using a CO2 gas analyzer. These data contribute to the long-term study of ocean carbon uptake and air-sea gas exchange.

Use Cases

• Calculating air-sea CO2 flux based on measured partial pressure (fugacity) of carbon dioxide in water.
• Analyzing correlations between sea surface temperature and ocean carbon content across a Pacific transect.
• Validating regional ocean carbon models with in-situ salinity and barometric pressure observations.
• Studying temporal variability in surface ocean chemistry during a late-1994 research cruise.

Strengths

• Data collected during a dedicated 25-day oceanographic cruise (1994-11 05 to 1994-11-29), providing a continuous time series.
• Includes key variables for carbon cycle research: CO2 fugacity, salinity, SST, and atmospheric pressure.
• Hosted on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating validation and importance.

Limitations

• Column names and exact data structure are not provided in any source description.
• Conflicting metadata: last update dates differ significantly (1994-11-29 vs. 2026-03-05).
• Complete row count, file size, and license information are unavailable.
