VOS Santa Cruz 2014: Surface Ocean Carbon and Meteorology

Surface underway measurements from the research vessel Santa Cruz track carbon dioxide exchange and ocean conditions across the North Atlantic Ocean, North Sea, English Channel, and South Atlantic Ocean from January 17 to February 28, 2014. The dataset includes partial pressure of carbon dioxide in air and water, sea surface temperature, salinity, and barometric pressure, collected using a CO2 gas analyzer. It was produced by researchers from the French National Research Institute for Sustainable Development and Sorbonne University under cruise ID PASR20140117.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in the atmosphere and water.
• Analyzing the relationship between sea surface temperature and carbon dioxide solubility across ocean basins.
• Studying spatial variability of surface ocean carbon parameters along a ship's transect.
• Validating ocean carbon cycle models with in-situ underway observational data.

Strengths

• Provides high-temporal-resolution surface underway measurements across a wide geographic area spanning the Atlantic Ocean and adjacent seas.
• Includes directly measured, co-located variables (CO2 partial pressure, SST, salinity, barometric pressure) crucial for flux calculations.
• Data collection is attributed to specific research institutions and a documented cruise (PASR20140117).

Limitations

• Key metadata such as row count, file size, specific column names, and data license are missing from all platform entries.
• Conflicting 'last updated' dates (2014-02-28 vs. 2026-03-05) suggest potential metadata inconsistency across hosting platforms.
• The dataset is limited to a single six-week cruise, providing a snapshot rather than long-term time-series data.
