Measurements of 15+ chemical and physical ocean parameters, including alkalinity, dissolved inorganic carbon, and chlorofluorocarbons, were collected during a 26-day research cruise. The dataset was created by researchers from the Leibniz-Institut für Meereswissenschaften in 2006. It supports the International CLIVAR Global Ocean Carbon and Repeat Hydrography Program's mission to quantify changes in ocean carbon storage.
Use Cases
- Calculate ocean carbon uptake by analyzing partial pressure of CO2 (pCO2) surface underway measurements alongside dissolved inorganic carbon and alkalinity.
- Study water mass age and circulation using tracer data like CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), and SULFUR HEXAFLUORIDE (SF6).
- Model nutrient cycles by correlating NITRATE, NITRITE, PHOSPHATE, and SILICATE concentrations with physical parameters like SALINITY and WATER TEMPERATURE.
- Assess ocean acidification drivers by examining relationships between ALKALINITY, DISSOLVED INORGANIC CARBON, and hydrographic data from CTD profiles.
Strengths
- Includes 15+ co-located chemical and physical parameters per sample, enabling multivariate analysis.
- Data collected over a focused 26-day cruise (2006-07-12 to 2006-08-06) in the tropical Atlantic, providing a coherent snapshot.
Limitations
- Temporal coverage is limited to a single cruise in 2006, preventing analysis of long-term trends.
- Geographic scope is confined to the cruise track of R/V Meteor 68/3 in the North Atlantic Ocean.
