MAO1407 Second survey of Mahón continental shelf. Before the dradge action of Mahón harbour a first survey using multibeam echosounder was conducted in january 2014 in order to the map the benthic habitats that could be affected. In this new survey the aim is to determinate the extension and impact that dradge debries has caused in the seabed using geophisical techniques. Multibeam echosounder and parametric subottom profailer had been used in the area. Data gatered will show the extend and thickness of dradge debries.

The objective of the NUREIEVA-3D campaign is the acquisition of a high-resolution 3D seismic cube of the submarine extension of the Portmán Bay mining spill deposit, in the vicinity of Cartagena, Murcia province, in order to establish the geometry and three-dimensional internal structure of said reservoir. To carry out the campaign, it will be necessary to install, test and deploy from the ship a complete 3D seismic system that will be provided by the subcontracted company GeoSurveys

During the ABRIC-3 cruise, the acquisition of high resolution bathymetries of the fishing grounds in Blanes and Palamós submarine canyons have been carried out using the ship hull multibeamm echosounder. Sediment cores have been obtained to determine the rates of sedimentation in the axes of the canyons. TOPAS seismic profiles were also collected crossing the canyon rims and flanks..

Get more information regarding the characteristics and distribution of benthic habitats present inside the Columbretes Islands Marine Reserve with the objective of Develop a bionomic map that covers the total extent. The complementary objective is the realization of the benthic cartography. It is intended to achieve location and subsequent georeferencing of the upwelling of gases present in the environment of the volcanic archipelago that forms The study area of this campaign. Associated with this objective is intended to know the Bacterial community in the area of gaseous upwellings and a physicochemical characterization of these areas.
