Surface Underway Ocean Carbon and Temperature Measurements from RV Laurence M. Gould

NCEI Accession 0148772 contains surface underway data collected by the RV Laurence M. Gould across the North Pacific, South Atlantic, South Pacific, and Southern Oceans. The dataset includes measurements of barometric pressure, partial pressure of carbon dioxide in air and water, salinity, and sea surface temperature, collected using carbon dioxide gas analyzers and equilibrators. Data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory, NOAA's Earth System Research Laboratory, and the University of Colorado's Cooperative Institute for Research in Environmental Sciences.

Use Cases

• Analyzing air-sea CO2 flux gradients across major ocean basins based on partial pressure measurements.
• Calibrating and validating ocean carbon cycle models using in-situ salinity and temperature data.
• Investigating seasonal or spatial variability in Southern Ocean carbon uptake from time-series observations.
• Assessing the performance of autonomous carbon dioxide measurement systems like shower head chamber equilibrators.

Strengths

• Data collected across multiple major ocean basins, including the remote Southern Ocean (>60°S).
• Includes simultaneous measurements of atmospheric and aquatic partial pressure of CO2, enabling flux calculations.
• Associated with specific research cruises (e.g., 33LG20041230) and a defined data collection program (VOS_LMG_NOAA_2005).

Limitations

• Conflicting time ranges reported across sources: one source states 2004-12-30 to 2005-11-20, while another states 2004-12-31 to 2005-12-26.
• Column names and exact data structure are unknown, limiting immediate usability.
• Dataset size (rows, file size) is unspecified across all sources.
