Discrete water sample and profile measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, and hydrographic variables. Data were collected by researchers F. Pérez and T. Muller during a 14-day cruise of the R/V METEOR in January 1997. This dataset is part of the CARINA synthesis project for biogeochemical carbon system studies.
Use Cases
- Calculate ocean carbonate system parameters like pCO2 using measurements of dissolved inorganic carbon, alkalinity, pH, temperature, and salinity.
- Analyze relationships between nutrient concentrations (nitrate, phosphate, silicate) and biological activity indicated by chlorophyll a levels.
- Investigate water mass properties and vertical structure using profiles of potential temperature, salinity, and hydrostatic pressure.
- Assess dissolved oxygen levels in relation to biological and chemical processes captured during the cruise.
Strengths
- Includes 12 key biogeochemical and physical variables per sampling event.
- Data collected over a focused 14-day period in January 1997, providing a temporal snapshot.
- Part of the curated CARINA synthesis project, which aims for internal consistency.
Limitations
- Temporal coverage is limited to a single two-week cruise in 1997.
- Geographic coverage is restricted to the specific cruise track in the North Atlantic Ocean.
- Sample size (number of stations or profiles) is not specified in the provided information.
