Chlorophyll-a Measurements from Southern Australian Ocean Transit

Fluorometric chlorophyll-a analyses were collected during the RV Investigator voyage IN2024_T01 from Fremantle to Hobart. The Australian Ocean Data Network provides this dataset from the 12-day transit in March 2024, capturing phytoplankton biomass indicators. Measurements originate from underway seawater sampling and conductivity-temperature-depth (CTD) collections.

Use Cases

• Analyze spatial patterns of chlorophyll-a concentration along the Fremantle-to-Hobart transit track.
• Correlate phytoplankton biomass from chlorophyll-a measurements with discrete sampling depths from CTD collections.
• Model temporal variability of marine primary productivity during the March 2024 voyage period.
• Validate satellite ocean color data using in vitro fluorometric chlorophyll-a analyses from underway seawater.

Strengths

• Data collected during a dedicated 12-day research voyage (9-20 March 2024).
• Includes measurements from two complementary sources: underway seawater and CTD collections.

Limitations

• Unknown sample size (row count) and geographic resolution.
• Temporal coverage is limited to a single two-week period in March 2024.
