Description

Dataset abstract

These data consist of pre-processed echosounder observations in the Southern Ocean collected during the Antarctic Circumnavigation Expedition (ACE; Leg2-Leg3) using an EK60 GPT operating at 200 kHz. The instrument was calibrated at South Georgia during the expedition (Leg 3) and corrections were applied prior to calculation of the volume backscattering strength (Sv). The signal-to-noise ratio (SNR) was analysed and was deemed very poor at depths greater than 100 m. Therefore, only data collected between the transducer depth (8.4 m) and 100 m were archived.
