Meteor Cruise 32/5: Arabian Sea Carbon Dioxide and Sea Surface Measurements

NCEI Accession 0157410 contains surface underway data from the R/V Meteor cruise 32/5 in the Arabian Sea, Gulf of Oman, and Indian Ocean during July-August 1995. The dataset includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure. These data were collected by GEOMAR Helmholtz Centre for Ocean Research Kiel using barometric pressure sensors and CO2 gas analyzers.

Use Cases

• Calculating air-sea CO2 flux based on simultaneous atmospheric and aquatic partial pressure measurements.
• Analyzing the relationship between sea surface temperature and carbon dioxide solubility in the Arabian Sea.
• Validating regional ocean carbon cycle models with in-situ underway data.
• Studying seasonal monsoon effects on surface ocean chemistry using time-series data from a specific cruise.

Strengths

• Provides simultaneous, co-located measurements of carbon dioxide in both the atmosphere and ocean surface, a key pairing for flux calculations.
• Covers a specific, well-documented research cruise (Meteor 32/5) with a precise time range from 1995-07-14 to 1995-08-14.
• Hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating vetting and sustained availability.

Limitations

• Column names and the exact data structure are not specified in the provided metadata, complicating immediate analysis.
• Metadata conflicts on the 'last updated' date (1995-08-14 vs. 2026-03-06), creating uncertainty about provenance tracking.
• Dataset scale (row count, file size) is unknown, making it difficult to assess its granularity or volume.
