Discrete sample and profile data from the North Atlantic Ocean collected aboard the R/V Tyro during April-May 1990. The dataset includes measurements for dissolved inorganic carbon, alkalinity, nutrients, oxygen isotopes, and hydrographic variables. Data were collected by researchers from the Commonwealth Scientific and Industrial Research Organization and others as part of the CARINA synthesis project.
Use Cases
- Calculate ocean acidification parameters like pCO2 and pH from dissolved inorganic carbon and alkalinity measurements.
- Analyze relationships between nutrient concentrations (nitrate, phosphate, silicate) and biological activity using the discrete sample data.
- Study water mass formation and mixing using potential temperature, salinity, and hydrostatic pressure profiles from the CTD.
- Investigate carbon cycle processes using stable isotope tracers delta carbon-13 and delta carbon-14.
- Model dissolved oxygen distribution and its correlation with temperature and nutrient levels.
Strengths
- Includes 15 key chemical and physical variables for carbon system and biogeochemical studies.
- Data collected during a dedicated cruise (CARINA/64TR19900417) ensuring methodological consistency.
- Part of the CARINA international synthesis project, which performed internal consistency checks.
Limitations
- Single cruise provides a snapshot from April-May 1990, lacking temporal coverage for seasonal or long-term analysis.
- Geographic scope is limited to the specific cruise track of the R/V Tyro in the North Atlantic.
- Sample size is constrained by the number of discrete bottle casts and CTD profiles from one expedition.
