Chlorophyll-a Measurements from RV Investigator Voyage IN2024_T01, March 2024

The Australian Ocean Data Network provides chlorophyll-a data collected during the Marine National Facility RV Investigator voyage IN2024_T01. The voyage, titled 'Fremantle to Hobart, 2024 Transit', occurred from 9 to 20 March 2024. The dataset comprises in vitro fluorometric analyses from underway seawater and CTD collections, indicating phytoplankton biomass along the transit track and at discrete depths.

Use Cases

• Modeling spatial patterns of marine primary productivity based on chlorophyll-a measurements mentioned in the description.
• Analyzing phytoplankton biomass variability along a transit track based on underway sampling data.
• Studying vertical phytoplankton distribution based on conductivity-temperature-depth (CTD) collections.
• Investigating biogeochemical cycles in southern Australian waters using indicators of phytoplankton biomass.

Strengths

• Data originates from a defined research voyage (IN2024_T01) aboard the RV Investigator, a Marine National Facility vessel.
• The temporal coverage is precisely documented as 9-20 March 2024.
• The dataset includes measurements from two collection methods: underway seawater sampling and CTD casts.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic and temporal bias inherent to a single, short-duration transit voyage.
