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 ... proxy for MTLO abundance in the epi- and mesopelagic zones. Boosted regression trees and generalised ... additive mixed models were used to develop simple predictive models for backscatter in the epi- and ...
