MVSEIS Cruise (29HE20080516) carried out on the Research Vessel Hespérides in 2008, MVSEIS: Tectonic control, deep structure and the mud volcanoes of the Gulf of Cádiz characteristics. The main scientific objectives of the MVSEIS campaign can be summarized as follows: 1) Study the morphology and the internal geophysical configuration (seismic, magnetic and gravimetric) of the mud volcanoes and carbonate diapiric dorsal continental margins of the Gulf of Cádiz. 2) Identify, sample and photograph possible active structures of emissions of Fluids in the bottoms of diapiric ridges and mud volcanoes. 3) Sample gas hydrates associated with mud volcanoes and study the geothermal and oceanographic conditions for its formation. 4) Identify and sample biomineralizations (nodules, crusts, chimneys, etc.) by the action of micro / macro chemosynthetic organisms by anaerobic oxidation of methane and / or dissociation of hydrated gases (clathrates). 5) Recognize the role of global (paleo) oceanographic / climatic changes and tectonics in the formation and evolution of mud volcanoes, diapiric ridges carbonated, deep chemosynthetic reefs and associated biomineralisations

EXPLOSEA-1 Cruise (29HE20190214) carried out on the Research Vessel Hespérides in 2019, The objective of the EXPLOSEA 1 cruise is the exploration and multidisciplinary research of submarine hydrothermal vents of low to high temperature in the Atlantic mid-ocean ridge, to the north of the Azores Islands and in the Azores Islands. The survey will address the exploration and characterizations of the venting sites including the water column, the sediments and rocks that host the hydrothermal activity and the associated mineralizations. This cruise is part of the “Exploration of submarine hydrothermal vents and associated mineral deposits and geobio-systems (EXPLOSEA)” project (CTM2016–75947-R)

EXPLOSEA-2 Cruise (29SG20190611) carried out on the Research Vessel Sarmiento de Gamboa in 2019, The objective of the EXPLOSEA 2 survey is to investigate hydrothermal underwater emissions in marine bottoms of the South Shetland Islands (Antarctica). These emissions are related to themagmatic / volcanic activity of the Bransfield retro-arch basin (Bransfield Strait, Island of Deception and Byers Peninsula) and the subduction zone north of the South Shetland Islands

ESPOR Cruise (29HE20081101) carried out on the Research Vessel Hespérides in 2008, ESPOR( ESpaña-PORtugal) Joint Scientific Study of Spain and Portugal for the Extension of the Continental Shelf in the margin of Galicia Bank, in accordance with Article 76 of the United Nations Convention on the Law of the Sea.
