Brief description

This record describes scientific split-beam echosounder data collected on the RV Investigator voyage IN2019_V06, titled 'Tropical observations of atmospheric convection, biogenic emissions, ocean mixing, and processes generating intra-seasonal SST variability' which departed Darwin on the 19th of October 2019 and returned to Darwin on the 17th of December 2019 ,consisting of two legs.

Leg 1 - Darwin, 20:00, 19 October 2019 to Darwin, 19:00, 10 November 2019

Leg 2 - Darwin, 20:00, 11 November 2019 to Darwin, 08:00, 17 December 2019
