Chemical, physical, and profile data collected from the SAGAR SAMPADA research vessel in the Arabian Sea, Indian Ocean, and Laccadive Sea between March 1994 and May 1995. The dataset includes measurements of dissolved inorganic carbon, delta carbon-14, dissolved oxygen, nitrate, phosphate, silicate, salinity, and potential temperature. These data were collected by Ravi Bhushan of the Physical Research Laboratory using CTD and bottle instruments.
Use Cases
- Modeling oceanic carbon uptake and storage based on dissolved inorganic carbon (DIC) and delta carbon-14 measurements.
- Analyzing nutrient distributions and biogeochemical cycles based on nitrate, phosphate, and silicate data.
- Studying oceanographic profiles and water column properties based on CTD-derived salinity, temperature, and hydrostatic pressure.
- Investigating dissolved oxygen dynamics and potential hypoxia in the Arabian Sea.
- Calibrating regional ocean models with historical, discrete sample data from specific cruise tracks.
Strengths
- Data covers a specific time range from 1994-03-01 to 1995-05-03.
- Includes multiple chemical and physical variables relevant to ocean carbon and nutrient studies.
- Associated with specific cruise IDs SS-118 and SS-132, providing clear provenance.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to the specific cruises and time period.
