From May to December 2011, surface underway data were collected from the HEALY vessel across the Arctic Ocean, Beaufort Sea, Bering Sea, and other Pacific regions. The dataset includes barometric pressure, partial pressure of carbon dioxide in water, salinity, and sea surface temperature. Stewart C. Sutherland, Taro Takahashi of Lamont-Doherty Earth Observatory, and Colm Sweeney of NOAA Earth System Research Laboratory collected these data as part of the VOS_Healy_Lines_2011 project.
Use Cases
- Modeling ocean carbon uptake based on partial pressure of carbon dioxide measurements.
- Analyzing sea surface temperature and salinity correlations in Arctic waters.
- Studying atmospheric-sea surface interactions based on barometric pressure data.
- Tracking seasonal changes in marine carbon dioxide levels across the Pacific and Arctic Oceans.
Strengths
- Data covers a specific 7-month voyage from May to December 2011.
- Includes measurements from multiple instruments: a CO2 gas analyzer and a shower head chamber equilibrator.
- Geographic coverage spans several key regions: Arctic Ocean, Beaufort Sea, Bering Sea, Gulf of Alaska, and Northwest Passage.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
