Surface underway measurements of carbon dioxide partial pressure, salinity, and sea surface temperature were collected aboard the USCGC Healy during a 2015 Arctic research cruise. The dataset covers the Arctic Ocean, Beaufort Sea, Bering Sea, and North Pacific Ocean from August to October 2015. Data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory and the University of Colorado's Cooperative Institute for Research in Environmental Sciences.
Use Cases
- Calculate air-sea CO2 flux using partial pressure of carbon dioxide in water and barometric pressure measurements.
- Analyze relationships between sea surface temperature and carbon dioxide fugacity across Arctic and sub-Arctic waters.
- Investigate regional variability in surface ocean salinity and its correlation with carbon dioxide concentrations.
- Validate and calibrate satellite-derived sea surface temperature products with in-situ underway measurements.
Strengths
- Data collected during a dedicated 2-month Arctic research cruise (2015-08-09 to 2015-10-12).
- Includes key variables for carbon flux calculation: CO2 partial pressure, salinity, sea surface temperature, and barometric pressure.
- Geographic coverage spans multiple critical ocean basins: Arctic Ocean, Beaufort Sea, Bering Sea, Gulf of Alaska, and North Pacific.
Limitations
- Temporal coverage is limited to a single cruise in 2015, providing only a seasonal snapshot.
- Unknown row count and sample density prevent assessment of spatial resolution.
- Lack of column details and sample data hinders understanding of data structure and potential ancillary variables.
