12.5 kHz raw echosounder data collected on the Antarctic Circumnavigation Expedition during the austral summer of 2016/2017.
Dataset abstract These data consist of raw echosounder observations collected during ACE (Leg1-Leg3) using an EK80 WBT operating at 12.5 kHz. The instrument was calibrated at South Georgia during the expedition (Leg 3) and corrections were applied prior to calculation of the volume backscattering st...
