Full description

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2026_V01, titled "Cook Ice Ecosystems and Sediments (COOKIES)." The voyage took place between January 02, 2026 and February 25, 2026 (AEST), departing from Hobart and returning to Hobart.
