Resumo: | The optimization of Ifremer's survey as a support of MSFD monitoring has been available since 2016 on the offshore fisheries surveys. Several protocols have been implemented, such as the “seafloor litter” and “gelatinous zooplankton” protocols. The aim of both protocols is to respectively collect data about the spatio-temporal evolution of waste and determine their origin, and to monitor the biodiversity of gelatinous zooplankton. From September to November 2017, they were tested on coastal surveys: NOURSOM, NOURNEINE, NOURMONT, ORHAGO, and NURSE. These surveys were primarily deployed to estimate the bentho-demersal species stocks as well as their spatio-temporal and trophic dynamics by a standardized sampling. Thus, this paper aims to assess the feasibility and relevance of the two tested protocols in order to know if they can be sustained in these coastal surveys to meet the needs of the MSFD monitoring. Thereby, questionnaires were sent to each survey managers and DCSMM pilots of the concerned descriptors: the D1-PH “Biodiversity-Pelagic Habitats” and the D10 “Marine litter”. The answers show that the "seafloor litter" protocol is entirely achievable in these coastal surveys and highly relevant to the sampling carried out. On the other hand, the "gelatinous zooplankton" protocol is more difficult to implement and its relevance has yet to be confirmed, considering the biodiversity descriptor that it must assess.
