Southern Ocean Deep Chlorophyll Data from RV Investigator Voyage IN2020_V08

Southern Ocean observations collected during the RV Investigator voyage IN2020_V08 (SOLACE) from 4 December 2020 to 15 January 2021. The dataset contains oceanographic, biogeochemical, and biological measurements including temperature, salinity, chlorophyll, nutrients, and particulate organic carbon. It was compiled by the Australian Ocean Data Network to study deep chlorophyll maxima and carbon cycling processes.

Use Cases

• Modeling deep chlorophyll maxima structure based on chlorophyll fluorescence and environmental data.
• Analyzing carbon sequestration potential based on particulate organic carbon (POC) and primary productivity measurements.
• Investigating iron limitation in phytoplankton based on dissolved and particulate iron and biological iron uptake data.
• Studying water column properties based on CTD-derived temperature, salinity, and transmissivity profiles.

Strengths

• Data collected during a dedicated 43-day research voyage (IN2020_V08) across subpolar and polar Southern Ocean waters.
• Includes measurements from multiple platforms: CTD rosettes, trace-metal clean rosettes, Triaxus profilers, and Biogeochemical Argo floats.
• Covers a wide range of variables including physical, chemical, and biological parameters relevant to carbon cycling.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
