Campaña: 3LNO GROUNDFISH SURVEY (FLETAN NEGRO 3L 2017) 3LNO GROUNDFISH SURVEY (FLETAN NEGRO 3L 2017)
The surveys on NAFO Regulatory Area of Div. 3L (Flemish Pass) were initiated by Spain in 2003. The surveys were carried out by the R/V “Vizconde de Eza” following the same procedures and using the same bottom trawl net type Campelen. The main objectives of this survey time series are: a) to obtain abundance indices of the main exploited species, b) to study the structure and distribution of these demersal species in the area.

The northern "Contourite Depositional System" located within the Gulf of Cadiz is well studied and was drilled last year during IODP expedition 339. We aim to acquire 3 additional seismic lines over these drill sites towards the shallow shelf for sequence stratigraphic studies and acquire a connection profile to the southern part of the Gulf, along the Moroccan margin. The research along the Moroccan margin builds upon previous investigations (R/V Belgica 2002, 2005, 2008) and will focus on smaller current-related deposits in order to fully understand the hydro- and sediment dynamic picture of this area during the past 2.4 Ma. This will allow to better assess the evolution of cold-water coral ecosystems. This will be achieved by gathering additional seismic lines and perform hydrographic measurements. In the second half of June, several cores will be gathered from the southern part of the Gulf of Cadiz with the R/V Marion Dufresne. In order to visualize the subsurface of these core sites, 6 seismic profiles will be gathered, connecting these core sites.
