Chlorophyll-a Measurements from Fremantle to Hobart Transit 2024

Aggregating in vitro fluorometric chlorophyll-an analyses from the RV Investigator voyage IN2024_T01, which transited from Fremantle to Hobart between 9 and 20 March 2024. The data provides an indicator of phytoplankton biomass from underway seawater and conductivity-temperature-depth (CTD) collections.

Use Cases

• Analyze spatial patterns of phytoplankton biomass using chlorophyll-a measurements along the Fremantle to Hobart transit track.
• Compare chlorophyll-a concentrations from underway seawater sampling versus discrete CTD collection depths to study vertical variability.
• Correlate chlorophyll-a data with other oceanographic parameters to support studies of marine primary productivity in southern Australian waters.

Strengths

• Data collected during a defined 12-day research voyage (9-20 March 2024) providing temporal specificity.
• Includes measurements from two distinct collection methods: underway seawater and CTD casts, offering complementary data sources.
• Focuses on chlorophyll-a, a key indicator for phytoplankton biomass and oceanographic studies.

Limitations

• The sample size and number of data points (rows) are unknown, limiting assessment of statistical power.
• Data is available only in HTML and PNG formats, which may not be ideal for direct quantitative analysis without extraction.
• The license is not specified, which could create uncertainty for downstream use and redistribution.
