Chemical and physical oceanographic data collected during the TTO_TAS_Expeditions cruise on the KNORR from December 1982 to February 1983. The dataset includes measurements for dissolved inorganic carbon, alkalinity, temperature, salinity, and nutrients across the Caribbean Sea, North Atlantic Ocean, and South Atlantic Ocean. Data were collected by researchers from Columbia University's Lamont-Doherty Earth Observatory using CTD and bottle instruments.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical ocean nutrient distributions based on nitrate, phosphate, and silicate data.
- Studying ocean circulation and mixing using potential temperature and salinity profiles.
- Investigating radioactive tracer distributions using delta carbon-14, tritium, and radium isotope measurements.
Strengths
- Includes 13 distinct chemical and physical variables, such as dissolved inorganic carbon and alkalinity.
- Data collected over a specific 80-day cruise period from 1982-12-01 to 1983-02-18.
- Spatial coverage spans three major ocean regions: Caribbean Sea, North Atlantic Ocean, and South Atlantic Ocean.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1983-02-18; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment.
