Over 14 chemical and physical variables were measured in the Baffin Bay during a 1998 research cruise. The dataset includes dissolved inorganic carbon, alkalinity, nutrients, chlorophyll, and temperature profiles. 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.
- Model nutrient limitation for phytoplankton using vertical profiles of NITRATE, PHOSPHATE, and SILICATE alongside CHLOROPHYLL A.
- Analyze the relationship between WATER TEMPERATURE, SALINITY, and DISSOLVED OXYGEN concentrations across depth.
- Study carbon partitioning by correlating DISSOLVED ORGANIC CARBON with PARTICULATE ORGANIC CARBON and PARTICULATE ORGANIC NITROGEN.
- Validate regional ocean models with in-situ profiles of Potential temperature (theta) and HYDROSTATIC PRESSURE.
Strengths
- Includes 14 key biogeochemical variables for carbon cycle and ecosystem studies.
- Data contributed to the CARINA international synthesis project for internal consistency.
- Provides vertical profile data from CTD and discrete bottle samples.
Limitations
- Single cruise provides limited temporal coverage from April to July 1998 only.
- Geographic scope is restricted to stations in the Baffin Bay region.
- Sample size and row count are unknown, limiting statistical power assessment.
