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 ... pelagic open-ocean ecosystem are normally sparse or absent. Consequently, ecosystem models are limited in ... proxy for MTLO abundance in the epi- and mesopelagic zones.
