September to October 1986 data collection from the Bay of Biscay and North Atlantic Ocean. The dataset contains discrete sample and profile observations of ammonium, chlorophyll A, dissolved oxygen, nitrate, nitrite, salinity, total alkalinity, water temperature, pH, phosphate, and silicate. Data were collected by researchers from the Commonwealth Scientific and Industrial Research Organization and Instituto de Investigaciones Marinas de Vigo during the CARINA/29GD19860904 cruise using CTD and bottle instruments.
Use Cases
- Modeling ocean acidification by analyzing pH and total alkalinity (TA) measurements across depth profiles.
- Studying nutrient cycles and primary productivity through correlations between nitrate, nitrite, phosphate, silicate, and chlorophyll A concentrations.
- Investigating water mass properties and stratification using potential temperature (theta), salinity, and hydrostatic pressure data.
- Assessing dissolved oxygen levels in relation to temperature and biological activity for hypoxia studies.
Strengths
- Includes 13 distinct chemical and physical variables per observation, enabling multivariate analysis.
- Data is part of the CARINA international synthesis project, aimed at producing an internally consistent dataset for biogeochemical investigations.
Limitations
- Temporal coverage is limited to a single one-month cruise in 1986, providing a snapshot rather than a time series.
- Geographic scope is confined to specific stations in the Bay of Biscay and North Atlantic Ocean during the cruise.
- Sample size (row count) and data density (vertical profiles vs. stations) are unknown from the description.
