Chlorophyll-a Data collected during RV Investigator voyage IN2024_T01

This record describes a chlorophyll-a dataset collected during the Marine National Facility (MNF) RV Investigator voyage IN2024_T01, titled "Fremantle to Hobart, 2024 Transit." The voyage took place between 9 March and 20 March 2024 (AEST), departing Fremantle and concluding in Hobart. The dataset comprises in vitro fluorometric chlorophyll-a analyses of phytoplankton pigments obtained from both underway seawater sampling and conductivity-temperature-depth (CTD) collections. These measurements provide an indicator of phytoplankton biomass and variability along the transit track and at discrete sampling depths. The dataset contributes to understanding spatial patterns of marine primary productivity and supports oceanographic, ecological, and biogeochemical studies in southern Australian waters.
