Chlorophyll-a Measurements from Southern Australian Transit Voyage

CSIRO Marlin Data Catalogue provides chlorophyll-a data from the RV Investigator voyage IN2024_T01. The dataset comprises in vitro fluorometric analyses of phytoplankton pigments from underway and CTD seawater sampling between 9 and 20 March 2024. It measures phytoplankton biomass variability along the Fremantle to Hobart transit track and at discrete depths.

Use Cases

• Analyze spatial patterns of phytoplankton biomass using chlorophyll-a measurements along the transit track.
• Model primary productivity by correlating chlorophyll-a data from discrete CTD sampling depths with oceanographic conditions.
• Study phytoplankton variability in southern Australian waters using underway seawater sampling data collected in March 2024.

Strengths

• Data collected during a dedicated 12-day oceanographic transit voyage.
• Measurements provide an indicator of phytoplankton biomass from both underway and CTD collections.
• Contributes to understanding marine primary productivity in a defined geographic region.

Limitations

• Specific sample count, row count, and column details are unknown.
• Data is limited to a single transit event in March 2024, offering a temporal snapshot.
• Available file formats are HTML and PNG, which may not be ideal for direct quantitative analysis.
