NCEI Accession 0116136 contains discrete sample and profile observations of dissolved inorganic carbon, alkalinity, pH, nutrients, temperature, and salinity. Data were collected by researchers from Duke University and the Rosenstiel School of Marine and Atmospheric Science during the ROGER REVELLE cruise in the South Pacific Ocean from December 2, 1997, to January 3, 1998. Measurements were taken using CTD and bottle instruments as part of the CLIVAR Ross Sea program.
Use Cases
- Model ocean acidification by analyzing trends between pH, dissolved inorganic carbon, alkalinity, temperature, and salinity.
- Study nutrient limitation in marine ecosystems by correlating nitrate, phosphate, silicate, and ammonium measurements.
- Calculate carbon export potential by examining relationships between particulate organic carbon, particulate organic nitrogen, and total organic carbon.
- Characterize water masses using hydrographic profiles of potential temperature (theta), salinity, and hydrostatic pressure.
- Assess biological oxygen consumption by analyzing dissolved oxygen levels alongside nutrient and carbon data.
Strengths
- Includes 16 distinct chemical and physical variables per observation, such as ALKALINITY, DISSOLVED INORGANIC CARBON, NUTRIENTS, and temperature.
- Data collected over a focused 33-day research cruise, providing a temporally coherent snapshot.
Limitations
- Sample size is unknown but likely limited to the specific cruise track and duration.
- Data is from a single cruise in 1997-1998, limiting temporal and spatial generalizability.
- Potential for instrument-specific measurement error inherent to CTD and bottle sampling methods.
