BUSCADOR RECOLECTA

FILAMENT Cruise (29HE19970926) carried out on the Research Vessel Hespérides in 1997, Incident flux on the continental shelf between the Strait of Gibraltar and Cape Ghir. The main objectives of the campaign were to quantify the branch of the Canary Current that affects the slope and the continental shelf of northwest Africa between the latitudes of the Strait of Gibraltar and Cape Ghir, its recirculation in the margin near the slope in the form of a jet coastal barocino, and its new integration to the interior ocean in the filament area of ​​Cabo Ghir. Other complementary objectives were to determine the concentrations of dissolved nutrients, respiration rates and productivity, and characterization of the water masses of the area in terms of dissolved aluminum

HUMBOLT Cruise (29HE20090305) carried out on the Research Vessel Hespérides in 2009, Study of the Humboldt Current. Oceanographic and training research campaign organized by the Spanish National Research Council and the Faculty of Biological Sciences of the Catholic University of Chile, where researchers from both institutions will participate, plus the University of Concepción and the EXPLORA Program of CONICYT

MOC-TRANSIT Cruise (29HE20100315) carried out on the Research Vessel Hespérides in 2010, MOC "Oceanic Memory of the Climate: Intermediate water flow and its transformation into surface waters in the Equatorial Atlantic"

MOC2EQ Cruise (29HE20100402) carried out on the Research Vessel Hespérides in 2010, MOC "Oceanic Memory of the Climate: Intermediate water flow and its transformation into surface waters in the Equatorial Atlantic ". Discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) obtained during the cruise MOC2EQ carried out from 5 April to 16 May 2010

TIC-MOC Cruise (29HE20150305) carried out on the Research Vessel Hespérides in 2015, TIC-MOC Tipping Corners in the Meridional Overturning Circulation. The principal objective of the cruise is to characterize the dynamics of the encountering of the Brazil and Malvinas Currents in the Brazil-Malvinas Confluence region. Specific objectives include the characterization of the water masses arriving to the confluence region, the description of the transformations experienced by these water masses , the definition of the frontal systems, the computation of water and property balances, and a description of the principal biogeochemical processes. During the TIC-MOC cruise we will make several stops at specific points (hydrographic stations) to collect data that will allow us to characterize this frontal system. In the hydrographic stations, measurements of physicochemical parameters (speed, temperature, salinity, and turbidity, all depending on the pressure) and biogeochemical (fluorescence, nutrients and dissolved oxygen) will be made. To do this, a rosette will be lowered to the bottom for taking samples of water at 24 depths, together with a CTD (measurements with high vertical resolution of salinity, temperature, dissolved oxygen, fluorescence and turbidity) and LADCP (measurements of the velocity of the Water). The samples of water that we will collect will be used for the determination of inorganic nutrients, microbial respiration, carbon and particulate and dissolved organic nitrogen, particulate and total organic phosphorus

RETRO-BMC Cruise (29HE20170408) carried out on the Research Vessel Hespérides in 2017, The RETRO-BMC aimed at studying the variability of the Malvinas-Brazil Confluence region at the mesoscale and submesoscale, including thermohaline intrusions and the river plume. A secondary objective was to gather combined current+hydrography data in the Beagle Channel

RETRO-ERZ Cruise (29HE20180426) carried out on the Research Vessel Hespérides in 2018, The main objective of this cruise was to study in detail the area of interaction between the western border current NBC (North Brazil Current) and the zonal current EUC (Equatorial UnderCurrent). Traffic maps acquired from numeric models and dynamic height satellite images helped locate the retroflection of NBC and the origin of the EUC. The region was sampled by the SeaSoar CTD undolutor, CTD + Rosette + LADCP and the microstructure profiler. The dynamic field of the study area was observed through the ADCP, distribution of the currents at 80 meters depth

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

CANOA-07 Cruise (29GD20071025) carried out on the Research Vessel García del Cid in 2007, The main objective of the cruise is to study the distribution of water masses in the coastal transition zone off the northwestern Morocco coastline,between the strait of Gibraltar and the Canary Island.This is the region where a substantial inflow of oceanic waters take place.These waters recirculate southwest as a narrow band along the continental slope ,with a fraction probably being diverted offsshore near Cape Ghir.The cruise will have a high resolution grid of hydrographic stations that should serve to understand the recirculation patterns.In each station we will lower a CTD to measure the salinity and temperature of the water, and we will take samples at 12 different depths with 12 botlle rosette.During the survey the ship will make continous measurements of surface salinity ,temperature and velocity.Finally during the cruise we will install two subsurface moorings at the continental slope.These moorings will contain both moroocan and spanish instruments to internally register the water flow velocity(currenmeters and spectrophotometer).The instruments will not reach the surface, the shallowest instrument being at a depth of about 100 m ,so they will caouse no sort of interference with navigation in the area.These instruments will be recovered in a second joint cruise, between Morooco and Spain ,to be carried out one year later

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
