This paper contains the report on outcomes of the work carried out by France and, in part by the CCAMLR Secretariat, proposed by France at CCAMLR-XXXVII, as endorsed by the Commission. The satellite overwatch project involved the receipt of images from target surveillance areas within the Convention Area, which were provided from the European Space Agency to the French Fisheries Maritime Control Center (FMCC). Part A of the paper reports on images analysed by the French FMCC containing a geographical position which were provided to the CCAMLR Secretariat for comparison with CCAMLR VMS data. The Secretariat was provided with 44 operable images, which corresponded with two CCAMLR authorised vessels.
