1992-12-03 to 1993-03-19 data includes dissolved inorganic carbon, pH, temperature, salinity, nutrients, and chlorophyll measurements. The dataset was collected from the SHIRASE research vessel in the Indian Ocean, South Pacific Ocean, and Tasman Sea during the CARINA/JARE34 cruise. Data were gathered by researchers from the Meteorological Research Institute using CTD and bottle instruments.
Use Cases
- Analyze dissolved inorganic carbon and pH columns to study ocean acidification trends in the Southern Ocean.
- Model relationships between nutrients (nitrate, phosphate, silicate) and biological indicators (chlorophyll a, phaeophytin) for phytoplankton studies.
- Calibrate hydrographic models using concurrent measurements of salinity, water temperature, and potential temperature (theta).
- Assess dissolved oxygen levels alongside carbon system variables for biogeochemical process investigations.
Strengths
- Includes 14 specific chemical and physical variables per observation.
- Data collected over a 4-month cruise across three distinct ocean regions.
- Part of the CARINA international synthesis project for internally consistent biogeochemical data.
Limitations
- Sample size and row count are unknown, limiting statistical confidence.
- Data is from a single cruise in 1992-1993, offering a limited temporal snapshot.
- Affiliation of one contributor (N. Sato) is unknown, affecting provenance clarity.
