IN2018_V05: Biogeochemical Data from the Polar Front South of Tasmania

October-November 2018 data collected during the IN2018_V05 voyage south of Tasmania. The dataset includes CTD nutrients, chlorophyll, and oxygen, as well as underway phytoplankton physiology and pCO2 measurements, used in a 2020-2021 Honours thesis. Data were collected by researchers from the Australian Ocean Data Network.

Use Cases

• Analyze biogeochemical variability based on CTD nutrient, chlorophyll, and oxygen profiles.
• Model phytoplankton physiology dynamics based on underway measurements.
• Investigate ocean carbon cycling based on underway pCO2 data.
• Study the physical-biological coupling in the Polar Front meander region south of Tasmania.

Strengths

• Data collected during a dedicated oceanographic voyage in October-November 2018.
• Includes multiple complementary data types: CTD profiles and underway measurements.
• Data were used in a formal academic thesis (2020-2021), suggesting a level of validation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Some data are duplicated in a different format on another platform (CSIRO Data Trawler), which may cause confusion.
