Surface underway measurements of carbon dioxide partial pressure, salinity, sea surface temperature, and barometric pressure were collected aboard the RV Nathaniel B. Palmer during a 28-day research cruise in the South Pacific Ocean. The dataset was produced by researchers from Columbia University's Lamont-Doherty Earth Observatory and the University of Colorado's Cooperative Institute for Research in Environmental Sciences. Observations were recorded between December 6, 2015, and January 2, 2016.
Use Cases
- Modeling air-sea carbon dioxide flux using partial pressure of carbon dioxide - water and barometric pressure measurements.
- Analyzing the relationship between sea surface temperature and salinity with carbon dioxide fugacity to study oceanic carbon uptake.
- Calibrating and validating regional carbon cycle models in the South Pacific Ocean using in-situ chemical and physical data.
- Investigating short-term variability in surface ocean chemistry during a Southern Hemisphere summer research cruise.
Strengths
- Data includes four key variables (BAROMETRIC PRESSURE, Partial pressure of CO2, SALINITY, SEA SURFACE TEMPERATURE) for carbon cycle analysis.
- Measurements were collected over a continuous 28-day period in a targeted ocean region.
- Data provenance is clear, citing specific principal investigators and institutions.
Limitations
- The dataset's size, row count, and sampling resolution are unknown.
- Geographic coverage is limited to the specific cruise track of the RV Nathaniel B. Palmer over one month.
- Data is from a single cruise, limiting conclusions about seasonal or interannual variability.
Provenance
