IN2024_T01: Chlorophyll-a Measurements from Southern Australian Transit

Chlorophyll-a data from the RV Investigator voyage IN2024_T01 provides an indicator of phytoplankton biomass along a transit from Fremantle to Hobart. Measurements were collected via in vitro fluorometric analysis of seawater samples from both underway and CTD collections between 9 and 20 March 2024. This dataset supports studies of spatial patterns in marine primary productivity and ecological variability in southern Australian waters.

Use Cases

• Mapping phytoplankton biomass spatial variability based on underway sampling.
• Analyzing vertical chlorophyll-a profiles from discrete CTD collection depths.
• Investigating marine primary productivity patterns along a transit track.
• Calibrating or validating satellite ocean color data with in situ measurements.

Strengths

• Data is associated with a specific, documented research voyage (IN2024_T01) on a national facility vessel.
• Provides measurements from two complementary sampling methods: underway surface water and discrete-depth CTD casts.
• Covers a defined temporal range (9-20 March 2024) and geographic track (Fremantle to Hobart).

Limitations

• Column names, row counts, and file size are unspecified, limiting assessment of structure and scale.
• License and author information are not provided, restricting clarity on reuse permissions.
• Metadata freshness is inconsistent, with last update dates differing between platform entries.
