The item is made of 2 files, of which 1 is the dataset and the other include a small description of the measured variables.-- Dataset contributed to the Project Carbochange.-- More information in http://hdl.handle.net/10261/115854, This dataset gathers discrete measurements of CO2 (pH and alkalinity) and hydrographic variables (salinity, temperature, dissolved oxygen, nitrate, phosphate and silicate) obtained during the cruise OVIDE 2006 carried out from 23 May to 26 June 2006. pH was measured spectrophotometrically following the Clayton and Byrne (1993). This method consists on adding a dye solution to the seawater sample, so that the ratio between two absorbances at two different wavelengths is proportional to the sample pH. Alkalinity was measured using an automatic potentiometric titrator Titrando 809 Metrohm, with a Metrohm 6.0232.100 combination glass electrode and a Pt-1000 probe for temperature measurement following the methodology given by Pérez and Fraga (1987). Dissolved oxygen was analyzed following the widely applied Winkler method. Determinations of nitrate, phosphate and silicate were carried out following methods described by Hansen and Grassoff (1983) Salinity and Temperature were recorded with a CTD probe, Spanish Project (CTM2007-28896-E), French OVIDE Project supported by CNRS, and CARBOOCEAN (511176GOCE), No

ECOQUIM Cruise (29HE20060102) carried out on the Research Vessel Hespérides in 2006, Chemical Ecology of Antarctic invertebrates. The objective of this research is to obtain bioactive substances from Antarctic benthic invertebrates that provide information on the chemical ecology of the species involved, and that may be useful for their pharmacological potential. The material will be collected in the Bransfield Strait and later processed at the Gabriel de Castilla Antarctic Spanish Base on Deception Island.The ECOQUIM-2 cruise was carried out around Deception Island, Livingston Island and their vicinities (South Shetland Islands) on board the Spanish RV BIOHespe´rides. Two different sampling devices (Agassiz trawl and rocky dredge) were used to obtain the samples at depths from 25–215 m

BENTART-06 Cruise (29HE20060115) carried out on the Research Vessel Hespérides in 2006, The objective of this research is the study of benthic ecosystem in the southern Shetland Islands, Antarctic Peninsula and Bellinghausen Sea, very unknown areas. Samples of physical-chemical parameters of the water, biological and sediment column will be made, using dredges, biological fishing nets and an underwater robot to obtain photographs and record video. The analysis will allow us to see the effects of Agassiz-type trawl fishing techniques, as well as to establish a protocol for the minimization of the negative effects of these gear and the conservation of the benthic ecosystem

CONAFRICA Cruise (29HE20060322) carried out on the Research Vessel Hespérides in 2006, "The African connection in the waters of the Canary Current" CONAFRICA. The objective of this project is to study the drift of zooplankton and ichthyoplankton in the filaments that occur in the African upwelling . To do this, samples of the upwelling will be taken and it will be verified that the species of larvae of fish transported coincide with the presence of larvae of the same species in the Great Canary platform . The work area will be swept continuously to obtain acoustic density maps. The zooplankton and ichthyoplankton will be analyzed from the vessel, obtaining synoptic maps of the hydrological conditions, fluorescence, abundance and metabolic activity of the plankton and the distribution of pelagic fish

MARSIBAL-06 Cruise (29HE20060429) carried out on the Research Vessel Hespérides in 2006, "Integrated Geological and Geophysical Studies in Southern Iberia Margins and Sedimentary Basins: Architecture and sedimentary processes" (MARISBAL Project) .The campaign plan included the collection of the following data with different acoustic and sampling techniques: · Obtaining profiles of high resolution monocanal seismic (air guns - "slevee guns" -). · Obtaining profiles with the TOPAS parametric probe. · Obtaining acoustic records with the EA-600 probe.· Obtaining reflectivity data and multibeam depth probe with an EM-120 multibeam probe system. · Obtaining sediment samples with the gravity core

IMPULS Cruise (29HE20060516) carried out on the Research Vessel Hespérides in 2006, South Iberian Margin Paleoseismological integrated stUdy of large active Structures (IMPULS). The IMPULS project is based on a multidisciplinary and integrated onshore-off shore neotectonic and paleoseismological study of the Carboneras Fault Zone (CFZ) at the SE margin of the Iberian Peninsula. In order to obtain the resolution required to study the vertical geometry of active faults in South Iberi-an Margin (e.g the Carboneras Fault) we tested a new high-resolution multi-channel seismic system onboard the RV Hespérides

SWIM Cruise (29HE20060531) carried out on the Research Vessel Hespérides in 2006, Earthquake and Tsunami Hazards in the Southwest Iberian Margin : High-resolution imaging of active faults and paleoseismic signature (SWIM) During June 2006 we carried out the ESF-EuroMargins SWIM marine geophysical cruise on board the Spanish RV Hespérides (PI. E. Gràcia) with the main objective to characterize the geometry, deep structure and timing of deformation of the active faults located at the westernmost Gulf of Cadiz (SW Iberian Margin). We acquired sixteen high-resolution multi-channel seismic (MCS) profiles together with Simrad EM120 swath-bathymetry and TOPAS sub-bottom profiler, totalizing more than 2700 km of data

RODA-I Cruise (29HE20060811) carried out on the Research Vessel Hespérides in 2006, Oceanic eddies and Atmospheric Deposition in the Canary Current (Subtropical East Atlantic): monitoring, biological and biogeochemical effects, and flows to the deep ocean (RODA). RODA I was planned to evaluate the role of the Canary eddy field in the enhancement of organic matter fluxes
