Baltic Sea Surface Carbon Dioxide and Oceanographic Measurements

Surface underway measurements of partial pressure of carbon dioxide (pCO2) in water and atmosphere, sea surface temperature, sea surface salinity, and barometric pressure were collected during M/V Tavastland cruises in the Baltic Sea from October 2019 to January 2020. A General Oceanics pCO2 system (model 8050) was used, with detailed methodology following Pierrot (2009). The dataset likely contains time-series records of these parameters for studying carbon exchange and oceanographic conditions.

Use Cases

• Calculating air-sea CO2 flux based on simultaneous water and atmospheric pCO2 measurements.
• Monitoring seasonal changes in sea surface temperature and salinity in the Baltic Sea during autumn/winter.
• Validating ocean carbon models using in-situ pCO2 data collected with a standardized GO system.
• Assessing ocean acidification trends from measured partial pressure of carbon dioxide in surface water.

Strengths

• Provides simultaneous measurements of water and atmospheric pCO2, sea surface temperature, and salinity, enabling flux calculations.
• Data collection follows a documented and standardized methodology using a General Oceanics 8050 system as described in Pierrot (2009).
• Specific instrumentation details are provided, including intake depth (6m), sensor types (SBE38), and air inlet location (30m above sea level).

Limitations

• Column names and exact data structure are unknown, limiting precise understanding of the dataset's format.
• Row count, dataset size, and license information are not provided by any source.
• Conflicting last updated dates exist between sources (2026-03-05 and 2020-01-02), indicating potential metadata inconsistency.
