Analysis of calibrated seafloor backscatter for habitat classification methodology and case study of 158 spots in the Bay of Biscay and Celtic Sea

Autor: Ridha Fezzani, Laurent Berger

Publikováno v: Marine Geophysical Research (0025-3235) (Springer), 2018-06, Vol. 39, N. 1-2, P. 169-181

An automated signal-based method was developed in order to analyse the seafloor backscatter data logged by calibrated multibeam echosounder. The processing consists first in the clustering of each survey sub-area into a small number of homogeneous se
