IN2019_V01: Phytoplankton Biogeochemistry from East Antarctic Voyage, 2019

Biogeochemical data were collected during the IN2019_V01 voyage of the RV Investigator in the Southern Ocean from January to March 2019. The study, led by the Australian Antarctic Division, investigated the effects of iron and light on phytoplankton growth off East Antarctica. Data include CTD nutrients, chlorophyll, oxygen, underway phytoplankton physiology, and pCO2 measurements.

Use Cases

• Modeling phytoplankton growth responses based on iron and light incubation experiments mentioned in the description
• Analyzing spatial patterns of nutrients and chlorophyll from CTD data collected off East Antarctica
• Studying carbon cycling and ocean acidification based on underway pCO2 measurements
• Calibrating satellite ocean color data using in-situ chlorophyll and physiology measurements

Strengths

• Data originates from a dedicated research voyage (IN2019_V01) with a clear scientific purpose led by the Australian Antarctic Division
• Includes multiple complementary data types: CTD profiles, underway measurements, and controlled incubation experiments
• Associated incubation experiments were performed for a PhD, suggesting a structured experimental design

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The description notes some data are duplicated in a different format on another platform, which may require deduplication
