Chlorophyll-a data collected during the RV Investigator voyage IN2024_T01 from Fremantle to Hobart between 9 and 20 March 2024. The dataset comprises fluorometric analyses of phytoplankton pigments from underway seawater and CTD collections, providing an indicator of biomass. It is hosted by the Australian Ocean Data Network and contributes to studies of marine primary productivity in southern Australian waters.
Use Cases
- Analyze spatial patterns of phytoplankton biomass based on chlorophyll-a measurements along the transit track.
- Study vertical distribution of primary producers based on chlorophyll-a data from discrete CTD sampling depths.
- Model marine primary productivity variability in southern Australian waters based on the chlorophyll-a indicator.
- Correlate phytoplankton biomass with other oceanographic parameters collected during the voyage.
Strengths
- Data is temporally precise, collected during a specific voyage from 9 March to 20 March 2024.
- Spatial coverage is defined along a transit track between Fremantle and Hobart in southern Australia.
- Measurements are derived from both underway seawater sampling and conductivity-temperature-depth (CTD) collections, providing surface and depth profiles.
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 freshness should be verified; the record was last updated on 2026-05-05.
