CARINA project data from the 1992 METEOR cruise provides discrete and profile measurements of dissolved inorganic carbon, alkalinity, nutrients, and hydrographic variables. Scientists from the Institute Fuer Meereskunde, Marianda Marine Analytics and Data, and the University of Hamburg collected the data using CTD and bottle instruments. Observations were made in the North Atlantic Ocean during a three-week period from May 9 to June 2, 1992.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH using measurements of ALKALINITY and DISSOLVED INORGANIC CARBON.
- Analyze nutrient distributions and their correlations with carbon system variables using NITRATE, PHOSPHATE, and SILICATE columns.
- Model water mass properties and mixing by examining profiles of SALINITY, WATER TEMPERATURE, and Potential temperature (theta).
- Investigate relationships between dissolved oxygen and carbon chemistry using the DISSOLVED OXYGEN and DISSOLVED INORGANIC CARBON measurements.
Strengths
- Internally consistent data set produced by the international CARINA synthesis project for biogeochemical investigations.
- Includes 11 key chemical and physical variables per observation, such as carbon parameters, nutrients, and hydrographic data.
Limitations
- Data is from a single, short cruise in 1992, providing only a temporal snapshot with limited seasonal or interannual context.
- Geographic coverage is restricted to the specific cruise track of the METEOR in the North Atlantic Ocean.
