BUSCADOR RECOLECTA

CASCADES-2 Cruise (29GD20090313) carried out on the Research Vessel García del Cid in 2009, To study the Interaction between the submarine cascades and deep ecosystems.CASCADES main objective is to study the processes of particle transport associated with the descent, in the form of underwater cascading , of dense waters formed in coastal environments, and at the same time, to evaluate in an interdisciplinary way the effects implications of this oceanographic phenomenon in ecosystems and deep living resources. To achieve this objective, it is necessary to record time series of oceanographic parameters in winter conditions (time when the underwater cascading) through the use of anchored instruments. This fact entails the need to request a minimum of two oceanographic campaigns (one to install the anchoring and another for its recovery).During the campaign CASCADES 2 the anchors of the first campaign will be recovered and three hydrographic transects will be carried out a CTD probe following a direction parallel to the orientation of the canyon, on the flank north, on the axis and on the south flank, and two perpendicular to the canyon. The stations will be separated one nautical mile from each other to characterize the structure in detail hydrographic and nephelide in the head of the submarine canyon and in the continental slope adjacent.also sediment samples will be collected
