ATOS-2 Cruise (29HE20090124) carried out on the Research Vessel Hespérides in 2009, ATOS project: Atmospheric inputs of organic carbon and pollutans to the polar ocean: rates, significance and outlook. "Quantify the atmospheric contributions of organic carbon and pollutants to the polar oceans, both those that occur at present and those that occurred in the last century and that have accumulated in the sea ice, being currently contributed to the ocean due to the melting of the ice in the poles. 1. Quantifying the atmospheric inputs of organic carbon and key organic pollutants both in aerosol and gaseous phases. 3. Evaluating the fate of the materials, by assessing their use by biota and transference up the food webs. 4. Evaluating the effects on microplankton as the entry points of the materials in the food web. 2. Elucidating the role of sea ice cover in controlling these rates and the inputs associated to sea ice melting

CARIBE-NORTE Cruise (29HE20090405) carried out on the Research Vessel Hespérides in 2009, Analysis of contact between the Caribbean and North American plates, from the Beata ridge (Dominican Republic) to the Anegada Passage. The cruise collected multibeam bathymetry, gravity, magnetic, high-resolution seismic and three-channel seismic reflection data. A set of 5 OBS were anchored along that transect on both sides of the Beata Ridge and 2 seismic land stations at the Beata and Alto Velo Islands, recorded continuously the airgun shots provided by the R/V Hesperides

ZEE-2009 Cruise (29HE20090805) carried out on the Research Vessel Hespérides in 2009, Exclusive Economic Zone cruise 2009. Oceanographic hydrographic study of the Spanish exclusive economic zone

MARBANGA Cruise (29HE20090825) carried out on the Research Vessel Hespérides in 2009, Study the paleoclimate of the last 30,000 years as a formula to understand the climatic conditions of today. MARBANGA cruise its whitin the proyect TOPOSED PROX Climatic forcings, tectonic controls and land-sea connections in the evolution of the Pleistocene and Holocene sedimentary record of the West Bank of the Bank of Galicia: magnetochemical proxies

HERMES Cruise (29HE20090915) carried out on the Research Vessel Hespérides in 2009, Hotspot Ecosystem research on the Margins of European Seas (HERMES). Further multibeam surveying was completed and improved the resultion in an area where cold-water-coral ocurrences have been reported

ORCA Cruise (29HE20091017) carried out on the Research Vessel Hespérides in 2009, Origin and variability of the Canary Current (ORCA)

TASMANDRAKE Cruise (29HE20180111) carried out on the Research Vessel Hespérides in 2018, The general objective of the TASMANDRAKE project is the study of the onset and evolution of the Antarctic Circumpolar Current (ACC). Taking into account the allowed period and that the capabilities of the geophysical equipment on board cannot image the deep structures and sediments, the cruise cannot fulfill the objectives of the TASMANDRAKE Project pertaining to the opening of gateways and onset of the ACC. We have therefore developed and alternative plan for the DRAKE2018 cruise that will allow us to collect mid-penetration to shallow data from the southern Drake-Scotia area (58ºS/62ºS and 60ºW/50ºW) and the South Orkney Shelf (60ºS/63ºS and 50ºW/40ºW). With this kind of capabilities we target those objectives of the TASMANDRAKE Project dealing with: 1) the evolution of the ACC during the Pleistocene and the Holocene; and 2) near-surface structure of continental blocks (i.e., the South Orkney micro-continent and the platform surrounding Elephant Island) and age of the older oceanic crust in Drake Passage. The proposed work is aimed to help land- ocean correlations between the stratigraphy of Seymour/Marambio Island and Ocean Drilling Project Site 696, in order to better understand the break-up and paleogeographic evolution of these continental blocks. The proposed marine surveys will consist in the execution of predefined transects along which geophysical data will be collected. In addition, we expect to collect sediment cores in specific sites, in order to groundtruth seismic facies with sediment information and provide age constrains of the most recent (Quaternary-Pliocene) units

BRAVOSEIS-GALILEO-2018 Cruise (29HE20180217) carried out on the Research Vessel Hespérides in 2018, Bravoseis and Galileo-IHM. Bravoseis: Seismological study of the submarine volcanoes of the Bransfield Strait (Antarctica): geodynamic environment, tectonic activity, local structure and earthquake-volcanic activity. The aim of Galileo-IHM project is to record and study the signal received from the Galileo satellites in high latitude, and more precisely in the Antarctic, where there is more satellites available. This is the third survey of this project that ends in 2018. The main interest is focused in the Public Regulated Service (PRS) although the Open Service (OS) signal was observed too

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

ARIOS Cruise (29MY20180115) carried out on the Research Vessel Mytilus in 2018, ARIOS: Acidification in the estuaries and Iberian oceanic platform
