ARM-REC Cruise (29SG20220502) carried out on the Research Vessel Sarmiento de Gamboa in 2022, Search and location of the remains of the submarine in the area using side-scan sonar and visual identification with a mini submarine

Oceanographic data acquired during the ATLANTIS Cruise (29SG20220613) on board the Research Vessel Sarmiento de Gamboa in 2022, Study of the structure of the crust and uppermost mantle from NW Africa and West Iberia using wide-angle seismic data and streamer seismic records of the continental margin and the deep water basin

Oceanographic data acquired during the LISA Cruise (29SG20220616) on board the Research Vessel Sarmiento de Gamboa in 2022, LISA cruise has the objective of acquiring new geophysical data in a mostly unexplored region of the SW Iberia Margin, about which many questions exist posing problems to geological interpretation. The LISA cruise acquired geophysical data along a profile (the LISA profile) that cuts across the Ampere seamount, the West Horseshoe Abyssal Palin, the plate boundary region and intersection of the Tore-Madeira Rise with the Gloria fault, and the Atlantic oceanic crust. The cruise consisted on the acquisition of wide angle seismic reflection anf refraction data using 21 OBH from GEOMAR-Kiel and the UTM seismic source. Additional data acquired: magnetic, multibeam bathymetry and backscatter and parasound

Oceanographic data acquired during the eIMPACT-1 Cruise (29SG20220729) on board the Research Vessel Sarmiento de Gamboa in 2022, The general objective of e-IMPACT is to study the linkage between the dynamics of mesoscale and sub-mesoscale processes occurring along the life history of cyclonic and anticyclonic eddies in the Canary Eddy Corridor (CEC), and their effects on the structure and metabolism of the planktonic community, as well as in their role in the vertical carbon flux to the deep ocean. e-IMPACT will address the coupled dynamics between food-web diversity and function, in relation to the physical and chemical conditions, the origin and composition of DOC and POC and their contribution to remineralization rates in the twilight zone of the ocean

Oceanographic data acquired during the SINES Cruise (29SG20220911) on board the Research Vessel Sarmiento de Gamboa in 2022, The overall objective of this study is to identify the changes and risks for marine ecosystem functioning and its biodiversity deriving from the potential impact of climate change on Iberian Upwelling fronts

Oceanographic data acquired during the BLUEHARVESTING Cruise (29SG20221001) on board the Research Vessel Sarmiento de Gamboa in 2022, The cruise is designed to analyse the direct environmental effects on the seabed and the water column arising from the deployment and operation of a prototype polymetallic nodule collector. The state of the seabed before and after the passage of the nodule collector vehicle is investigated by recording a high-definition video installed on a remotely operated vehicle (ROV). The dispersion of the resuspended material plume by the nodule collector is monitored by a set of moorings deployed around the circulation zone of the nodule collector. Anchors include turbidimeters, current meters, a particle camera and a grain size analyser. Likewise, a transect of CTDs is repeated several times and a follow-up of the plume with the CTD behind the collector. The underwater sound impact produced by the nodule collector is recorded with a deep-sea hydrophone located at one of the anchors

Oceanographic data acquired during the eIMPACT-2 Cruise (29SG20221108) on board the Research Vessel Sarmiento de Gamboa in 2022, The general objective of e-IMPACT is to study the linkage between the dynamics of mesoscale and sub-mesoscale processes occurring along the life history of cyclonic and anticyclonic eddies in the Canary Eddy Corridor (CEC), and their effects on the structure and metabolism of the planktonic community, as well as in their role in the vertical carbon flux to the deep ocean. e-IMPACT will address the coupled dynamics between food-web diversity and function, in relation to the physical and chemical conditions, the origin and composition of DOC and POC and their contribution to remineralization rates in the twilight zone of the ocean

Oceanographic data acquired during the DESAFIO-1 Cruise (29SG20230201) on board the Research Vessel Sarmiento de Gamboa in 2023, The general objective of DESAFIO is to study the flow of particulate and active carbon (the one carried out by the migrating organisms of the zooplankton and micronekton), as well as the selection of meso- and bathypelagic migrants in the area detected between the upwelling of the African coast, the oligotrophic waters of the subtropical gyre, and the Azores current, ending in the productive waters north of the Azores. The campaign design, divided in two parts, will allow studying an important variety of productive scenarios in the ocean in two seasons of the annual cycle characterized by the highest productivity in winter and oligotrophy in autumn

Oceanographic data acquired during the STRENGTH Cruise (29SG20230315) on board the Research Vessel Sarmiento de Gamboa in 2023, The STREGTH cruise aims at providing information about the recent (Quaternary) activity of the active faults in the Moroccan and Spanish margins and about their tectonic structure, with special emphasis on the faults location, geometry and seismotectonic significance. The cruise is planned to acquire high-resolution bathymetry, image and seismic data from 15 March to 21 April 2023. The main goal of STRENGTH is collecting high-resolution bathymetry, image and seismic data with the Spanish R/V Sarmiento de Gamboa. For this we will use an autonomous underwater vehicle (AUV), a remote operated vehicle (ROV), a side-scan sonar (DT-1), sparker seismic system and a streamer with hydrophones, and deploy Ocean Bottom Seismometers (OBS) on the sea floor and we will use a group of air guns for the acoustic source

Oceanographic data acquired during the MARBEFES Cruise (29SG20230504) on board the Research Vessel Sarmiento de Gamboa in 2023, MARine Biodiversity and Ecosystem Functioning leading to Ecosystem Services. The project aims to evaluate and characterise the links between marine biodiversity, ecosystem functioning, ecosystem services and the resulting societal goods and benefits in coastal communities. The results will be captured in easy-to-use tools to help practitioners and policy to maximise the ecological value and optimise a sustainable socio-economic use of the marine system for current and future generations
