October to November 1997 data collection includes dissolved inorganic carbon, alkalinity, salinity, temperature, dissolved oxygen, and hydrostatic pressure from the North Atlantic Ocean. Measurements were taken from the R/V Knorr during the CARINA/316N19971005 cruise using CTD and bottle instruments. The data were collected by researchers from the University of Perpignan and others as part of the CARbon dioxide IN the Atlantic Ocean (CARINA) synthesis project.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH from paired dissolved_inorganic_carbon and alkalinity measurements.
- Analyze the relationship between water_mass characteristics using potential_temperature, salinity, and hydrostatic_pressure profiles.
- Model dissolved_oxygen distribution as a function of temperature and salinity for biogeochemical process studies.
- Validate and calibrate regional ocean carbon cycle models using in-situ dissolved_inorganic_carbon data.
- Investigate carbon system variability in the North Atlantic Ocean during the autumn 1997 period.
Strengths
- Internally consistent data set produced by the international CARINA synthesis project for biogeochemical investigations.
- Includes key carbon system variables (dissolved inorganic carbon, alkalinity) paired with standard hydrographic data (temperature, salinity).
- Data collected over a focused 45-day cruise in October-November 1997, providing a temporal snapshot.
Limitations
- Single cruise data from 1997, limiting temporal analysis and potentially representing seasonal conditions only.
- Geographic scope is limited to the specific cruise track of the R/V Knorr in the North Atlantic Ocean.
- Unknown sample size (row count) and potential for spatial gaps between discrete bottle stations.
