January 4 to February 1, 2017, discrete bottle profile measurements of dissolved inorganic carbon, alkalinity, CFCs, temperature, salinity, oxygen, and nutrients were collected during the R/V Maria S. Merian cruise MSM60 across the South Atlantic Ocean. The expedition followed the SAMBA/SAMOC line at 34°30'S, conducting full water depth sampling up to 5300 meters using a CTD/O2/lADCP rosette system. The data is part of the GO-SHIP Repeat Hydrography Section A10.5 program.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing deep-water circulation and ventilation based on chlorofluorocarbon (CFC-11, CFC-12) tracer data.
- Studying nutrient distributions and biogeochemical cycles based on nitrate, silicate, and phosphate measurements.
- Calibrating and validating oceanographic models based on full-depth temperature, salinity, and oxygen profiles.
Strengths
- Full water depth sampling up to 5300 meters, providing a complete vertical profile.
- Multiple co-located chemical and physical measurements (DIC, alkalinity, CFCs, nutrients, temperature, salinity, oxygen) per station.
- Data collected along a basin-wide section (34°30'S) as part of the standardized GO-SHIP repeat hydrography program.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
