North Atlantic Ocean profiles collected from discrete samples and CTD instruments aboard the TYRO vessel during April-May 1991. The data set includes dissolved inorganic carbon, dissolved oxygen, nutrients, salinity, and temperature measurements. It was collected by researchers from Commonwealth Scientific and Industrial Research Organization and Royal Netherlands Institute for Sea Research as part of the CARINA and WOCE AR07Eb projects.
Use Cases
- Calculate ocean acidification trends by analyzing DISSOLVED INORGANIC CARBON (DIC) and pH proxy relationships with SALINITY and WATER TEMPERATURE.
- Model nutrient cycling in the North Atlantic using NITRATE, NITRITE, phosphate, and silicate concentrations alongside hydrographic data.
- Assess ocean ventilation and oxygen levels by correlating DISSOLVED OXYGEN measurements with Potential temperature (theta) and HYDROSTATIC PRESSURE profiles.
- Validate regional carbon models using the internally consistent CARINA synthesis of subsurface DISSOLVED INORGANIC CARBON measurements.
- Study water mass properties and mixing by examining SALINITY and Potential temperature (theta) profiles collected via CTD.
Strengths
- Data is part of the CARINA synthesis project, an international effort producing a merged internally consistent data set for biogeochemical investigations.
- Includes multiple key ocean variables: DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, nutrients, salinity, and temperature from calibrated instruments.
- Provides profile data from CTD and discrete bottle samples, allowing vertical analysis of ocean properties.
Limitations
- Temporal coverage is limited to a single cruise from 1991-04-08 to 1991-05-15, offering only a snapshot.
- Geographic scope is restricted to the North Atlantic Ocean track of the TYRO vessel during this cruise.
- Sample size and row count are unknown, which may limit statistical power for some analyses.
