Southern Ocean Deep Chlorophyll Data from RV Investigator Voyage IN2020_V08

Marine National Facility RV Investigator voyage IN2020_V08 collected oceanographic and biogeochemical observations across the subpolar and polar Southern Ocean between 4 December 2020 and 15 January 2021. The dataset includes measurements of temperature, salinity, chlorophyll fluorescence, nutrients, particulate organic carbon, and dissolved iron. It was compiled to investigate the structure and environmental controls of deep chlorophyll maxima and phytoplankton productivity in the Southern Ocean.

Use Cases

• Modeling phytoplankton productivity based on chlorophyll fluorescence and nutrient measurements.
• Investigating carbon sequestration processes based on particulate organic carbon (POC) data.
• Analyzing the relationship between physical oceanography (temperature, salinity) and biological activity.
• Studying iron limitation in polar waters based on dissolved and particulate iron measurements.

Strengths

• Observations were collected using multiple advanced systems including CTD rosettes, trace-metal clean rosettes, Triaxus profilers, and BGC-Argo floats.
• Data covers a specific voyage (IN2020_V08) during the austral summer from 4 December 2020 to 15 January 2021.
• Measurements include a wide range of biogeochemical variables such as active fluorescence, net primary productivity, and biological iron uptake.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single research voyage.
