Surface Fugacity of CO2 and Related Variables in Gulf of Alaska and Bering Sea (2019)

This dataset contains surface underway measurements of fugacity of carbon dioxide (fCO2), sea surface salinity, sea surface temperature, and other parameters collected during NOAA Ship Oscar Dyson cruises DY190-6_L2, DY190-6_L3, DY190-7_L1, DY190-7_L2, DY190-8, DY190-9 (EXPORTS) and 33OA20190626, 33OA20190720, 33OA20190813, 33OA20190830, 33OA20190919, 33OA20191007 in the Gulf of Alaska, Bristol Bay, and North Pacific Ocean from June to October 2019. The effort supports coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).

Use Cases

• Analyze spatial and temporal patterns of surface ocean fCO2 in the Gulf of Alaska and Bering Sea.
• Calibrate and validate regional ocean acidification and carbon cycle models.
• Investigate drivers of sea surface carbon variability using concurrent salinity and temperature data.

Strengths

• High-resolution surface underway measurements provide detailed spatial coverage.
• Includes multiple related parameters (fCO2, salinity, temperature) for multivariate analysis.
• Collected during dedicated NOAA OAP cruises following standardized protocols.

Limitations

• Limited to surface observations; no vertical profile data.
• Temporal coverage is restricted to a single field season (June–October 2019).
• Metadata completeness is unknown; data quality may require manual inspection after download.
