BENTHOSCOPE2 - Article: Three-dimensional mapping of the benthic invertebrates biophony with a compact four-hydrophones array

This study provides the first maps of the Benthic Invertebrate Biophonies (BIB) at ecologically relevant scales and shows that they can be used to identify, quantify, follow and track benthic activity hot-spots. In combination with biological and ecological information, passive acoustic monitoring using such maps can be a powerful complementary tool for ecological studies, such as the quantification of grazing activity or the evaluation of the efficiency of marine ecologic restoration programs.
