A 1997 cruise in the South Pacific Ocean collected discrete sample and profile data on dissolved inorganic carbon, alkalinity, pH, nutrients, and physical oceanographic variables. The dataset includes measurements for 15 parameters like ammonium, nitrate, phosphate, silicate, dissolved oxygen, salinity, and temperature. Data were gathered by researchers from Oregon State University and the Rosenstiel School using CTD and bottle instruments during the CLIVAR Ross Sea program.
Use Cases
- Modeling ocean acidification by analyzing correlations between dissolved inorganic carbon, pH, alkalinity, temperature, and salinity.
- Studying nutrient limitation in phytoplankton by examining spatial profiles of nitrate, nitrite, phosphate, silicate, and ammonium.
- Calibrating biogeochemical models using concurrent measurements of particulate organic carbon, particulate organic nitrogen, and dissolved oxygen.
- Investigating water mass properties and circulation using profiles of potential temperature (theta), salinity, and hydrostatic pressure.
Strengths
- Includes 15 distinct chemical and physical variables per observation.
- Data collected over a focused 36-day research cruise in 1997.
Limitations
- Temporal coverage is limited to a single month in 1997, providing only a snapshot.
- Geographic scope is confined to the specific cruise track in the South Pacific Ocean.
- Sample size and row count are unknown, limiting statistical assessment.
