Ocean Carbon Chemistry from R/V Bjarni Saemundsson Cruises

From 2006-05-14 to 2019-10-21, this dataset contains surface underway chemical, meteorological, and physical measurements from R/V Bjarni Saemundsson cruises in the North Atlantic, Irminger Sea, and Iceland Sea. It includes sea surface temperature, equilibrator temperature and pressure, and mole fraction and partial pressure of carbon dioxide. The data were collected using a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Analyzing ocean carbon dioxide partial pressure (pCO2) trends based on PCO2TEQ measurements.
• Studying sea surface temperature (SST) variability in the North Atlantic based on SST column data.
• Calculating air-sea carbon dioxide fluxes based on mole fraction (xCO2) and equilibrator pressure (PEQ) data.
• Correlating meteorological conditions with ocean chemistry based on the combined physical and chemical measurements.

Strengths

• Contains a 13-year time series of observations from 2006 to 2019.
• Data is collected from specific, repeated cruises (R/V Bjarni Saemundsson) in defined ocean regions.
• Includes measurements from specialized instruments like a CO2 gas analyzer and equilibrator.

Limitations

• Column names and exact data structure are not provided in the metadata.
• There is a conflict in the 'last updated' metadata: one source states 2026-03-05, another states 2019-10-21.
• Dataset size and row count are unknown.
