Drake Passage Surface Water CO2 and Chemistry Time Series, 2002-2017

Discrete surface water measurements collected from the R/V Laurence M. Gould across the Drake Passage from 2002-03-08 to 2017-10 24. The data include partial pressure of CO2, dissolved inorganic carbon, nutrients, sea surface temperature, and sea surface salinity. These data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory as part of a time series program sampling approximately six times per year at 15 stations.

Use Cases

• Modeling ocean carbon uptake based on partial pressure of CO2 and dissolved inorganic carbon measurements.
• Analyzing nutrient dynamics (e.g., phosphate, nitrate, silicate) in relation to biological activity.
• Studying long-term trends in sea surface temperature and salinity in the Drake Passage.
• Calibrating satellite-derived sea surface data with in-situ discrete measurements.

Strengths

• Time series spans over 15 years, from 2002 to 2017.
• Program sampled approximately six times per year at 15 stations, suggesting consistent temporal coverage.
• Data includes multiple related chemical and physical variables (pCO2, DIC, nutrients, SST, SSS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the specific Drake Passage transect.
