The mapping of habitats off the coast of Congo was carried out by the Ifremer Deep-Sea Laboratory as part of the ANR CONGOLOBE project (2011-2015, coordinator Christophe RABOUILLE). The method used for this habitat mapping is based on the preliminary analysis of images acquired with the ROV Victor 6000 during two oceanographic campaigns: WACS (from 26/01/2011 to 25/02/2011, mission chief: Karine OLU) and CONGOLOBE (from 11/12/2011 to 12/01/2012, mission chief: Christophe RABOUILLE). The habitats were described at the finest level of analysis and then classified according to the EUNIS typology (https://www.eea.europa.eu/data-and-maps/data/eunis-habitat-classification-1). Data published in: Sen, A., B. Dennielou, J. Tourolle, A. Arnaubec, C. Rabouille and K. Olu (2017). Fauna and habitat types driven by turbidity currents in the lobe complex of the Congo deep-sea fan.

The mapping of pockmark habitats (cold fluid emissions) off the coast of Congo was carried out by Ifremer's Deep-Sea Laboratory as part of the WACS cruise. The method used for this habitat mapping is based on the preliminary analysis of videos acquired with the ROV Victor 6000 during the oceanographic cruise: WACS (from 26/01/2011 to 25/02/2011, mission leader: Karine OLU). The habitats were described at the finest level of analysis and then classified according to the EUNIS typology (https://www.eea.europa.eu/data-and-maps/data/eunis-habitat-classification-1). Data published in: Marcon, Y., H. Sahling, A.-G. Allais, G. Bohrmann and K. Olu (2014a). Distribution and temporal variation of mega-fauna at the Regab pockmark (Northern Congo Fan), based on a comparison of videomosaics and geographic information systems analyses."

The 62 RESSGASC campaigns allow the quarterly assessment of the quantities of various species (hake, sole, Norway lobster, etc.) discarded by fishing vessels (individuals below legal landing size). This information, together with data collected from the demographic structure of landings (using samples from auctions), is essential for the evolution of commercial fish stocks.
