Baltic Sea Carbon Dioxide and Temperature from Mooring Östergarnsholm

From 2005-05-31 to 2022-10-20, this dataset provides time-series measurements of the partial pressure of carbon dioxide (pCO2) and sea surface temperature from a moored buoy in the Baltic Sea. It is part of the international Global CO2 Time-series and Moorings Project, coordinated by UNESCO's IOCCP, involving groups from 18 countries. The data were collected using a bubble-type equilibrator and a CO2 gas analyzer.

Use Cases

• Analyzing seasonal and interannual variability of ocean pCO2 in the Baltic Sea based on high-resolution time-series.
• Calculating air-sea CO2 flux estimates using concurrent pCO2 and sea surface temperature measurements.
• Validating regional biogeochemical models with in-situ carbon dioxide data from a fixed mooring location.
• Investigating long-term trends in coastal ocean acidification drivers from a 17-year observational record.

Strengths

• Provides a long-term, high-resolution time-series covering a 17-year period (2005-2022).
• Part of a coordinated international project (Global CO2 Time-series and Moorings) involving 18 countries, suggesting standardized methodology.
• Data collection uses specific, named instruments (bubble-type equilibrator, CO2 gas analyzer).

Limitations

• Conflict in reported temporal coverage: two sources state the range ends in 2020-04-17, while another extends it to 2022-10-20.
• Metadata is incomplete across platforms, with unknown column names, row counts, and file size.
• The dataset's structure and specific variables beyond pCO2 and temperature are not detailed.
