1. Predicting distribution and relative abundance of mid-trophic level organisms using oceanographic parameters and acoustic backscatter

   Abstract:  Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the ... resilience to climate change. We used acoustic data collected at 38 kHz frequency across the Southern Ocean ... mesopelagic zones, using sea surface temperature, time of day (day/night) and depth.
