OISO-16 cruise data from 2008 provides surface measurements of dissolved inorganic carbon, alkalinity, temperature, and salinity in the Indian Ocean. The data is part of the OISO program, initiated in 1998, which collects repeated measurements along RV Marion-Dufresne lines in the South-Western Indian and Southern Oceans. These measurements are regularly included in international synthesis projects like SOCAT and GLODAP.
Use Cases
- Tracking ocean acidification trends based on dissolved inorganic carbon (DIC) and total alkalinity (TALK) measurements.
- Calibrating satellite-derived sea surface temperature data based on in-situ temperature measurements.
- Assessing carbon sink variability in the Southern Ocean based on repeated cruise line data.
- Validating global ocean carbon models based on data integrated into SOCAT and GLODAP.
- Studying biogeochemical parameter correlations based on associated nutrient, chlorophyll, and 13C measurements.
Strengths
- Data is part of a long-term monitoring program (OISO) initiated in 1998, providing a time-series context.
- Coverage complements the International Ocean Carbon Coordination Project (IOCCP) and is integrated into major international synthesis projects (SOCAT, GLODAP).
Limitations
- Column names and dataset size (rows) are unknown across all sources, limiting detailed structural understanding.
- There is a conflict in the 'last updated' metadata: one source lists 2008-02-05, while another lists 2026-03-05, suggesting potential metadata inconsistency.
