Over 23,000 stations from 94 global cruises form the basis for this World Ocean Circulation Experiment collection. This specific dataset contains discrete chemical and physical measurements, including dissolved inorganic carbon, alkalinity, and chlorofluorocarbons, collected from the R/V Hudson in the North Atlantic during June-July 1999. Data were gathered by researchers from BDR Research Ltd and the Bedford Institute of Oceanography using CTD and bottle instruments.
Use Cases
- Model ocean carbon uptake and storage using DISSOLVED INORGANIC CARBON (DIC) and TOTAL ALKALINITY (TA) measurements paired with SALINITY and WATER TEMPERATURE.
- Analyze relationships between nutrient cycles and carbon chemistry by correlating NITRATE, phosphate, silicate data with DIC and alkalinity.
- Study the penetration and distribution of anthropogenic tracers by examining CHLOROFLUOROCARBON-11 (CFC-11), CFC-12, and Carbon tetrachloride (CCL4) concentrations.
- Assess water mass properties and circulation in the North Atlantic using vertical profiles of HYDROSTATIC PRESSURE, temperature, salinity, and DISSOLVED OXYGEN.
- Calibrate or validate regional ocean models with in-situ physical and chemical profile data from the Davis Strait and Labrador Sea.
Strengths
- Data is part of a major international climate program (WOCE) covering approximately 23,000 stations globally.
- Includes multiple co-located variables (15+ chemical and physical parameters) per sampling event for multivariate analysis.
- Provides discrete, bottle-based measurements for key carbon system parameters (DIC, TA), often considered high-quality.
Limitations
- Temporal coverage for this specific accession is limited to a 17-day cruise in 1999.
- Spatial coverage is restricted to a single cruise track in the Northwest Atlantic, not globally representative.
- Data is over 25 years old, limiting analysis of recent ocean changes and anthropogenic impacts.
