BUSCADOR RECOLECTA

CANOA08-SUR Cruise (29SG20081102) carried out on the Research Vessel Sarmiento de Gamboa in 2008, A shallow mesoscale anticyclonic eddy, observed south of the Canary Islands with satellite altimetry, has been intensively studied with multiparametric sampling. The campaign involved multiparametric in situ sampling in the region off NW Africa, from Cadiz to Cape Verde and from the shelf break to the deep ocean: the measurements included hydrographic stations with Conductivity-Temperature-Depth (CTD) casts and water samples from a 24 Niskin-bottle rosette; continuous velocity data down to about 600 m depth with the VM-ADCP; CTD sampling with an undulating Nu-Shuttle platform; and the deployment of drifters drogued at about 100 m depth. These measurements were complemented with remote sensing data (SST and altimetry) for the whole NW Africa region

NITROALBORAN Cruise (29GD20080509) carried out on the Research Vessel García del Cid in 2008, During May 2008 Nitroalboran cruise was carried out on board of the oceanographic vessel “García del Cid. An important activity conducted during the NITROALBORAN research cruise is the collection of water samples for measurements and use in experiments. Upon reaching a station, a rosette sampler mounted with a conductivity, temperature, and depth recorder (called a CTD) and Niskin sampling bottles was lowered through the water to the bottom. The CTD measures how physical (water temperature,salinity, and density); chemical (dissolved oxygen); and biological (chlorophyll a fluorescence) characteristics change with water depth and produces a profile of theseparameters in the water column. Closure of the Niskin bottles can be triggered from the ship, allowing seawater to be collected at selected depths. During the Nitroalboran research cruises zooplankton was collected for experiments using plankton nets that are pulled, or towed, through the water

CANOA-08_NORTE Cruise (29GD20080518) carried out on the Research Vessel García del Cid in 2008, The NORTH campaign was carried out in May 2008 (CANOA08-NORTH) on the northern portion of the Gulf of Cádiz. The objective of the campaign was to study the intrusion of Mediterranean waters in the Gulf of Cádiz, with special emphasis on the structure of a Meddy detected in the area using altimetric data. This campaign used a Lowered Acoustic Doppler Profiler (ADCP) and a microstructure profiler (Turbomap) to study the currents and turbulence associated with the Meddy and in one of the submarine canyons south of the Iberian Peninsula
