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.

Oceanographic data acquired during the BOCATS-2-2023_LEG1 Cruise (29SG20230608) on board the ResearchVessel Sarmiento de Gamboa in 2023., BOCATS2, a continuation of the previous BOCATS project (2014-2017), will be a main contribution to the observation of the NA subpolar gyre by continuing the occupation of the biennial section A25-Ovide (2021 and 2023) within the framework of the international GO-SHIP programme. A particular focus will be given to the new challenge of assessing the variability of the deep circulation in the NA, improving the spatial-temporal resolution of deep currents and water mass characteristics by deploying a regional deep-ARGO array and, at a submilenary scale, using paleoceanographic data obtained in sedimentary records from key sites, such as the Bight and Charlie-Gibbs fracture zones. The high-quality observations foreseen in the SPNA will contribute to the early detection of the alteration of the carbon cycle allowing the precise estimation of the heat, CO2 and N2O storage rates and, ultimately, to find the connection between these changes and the variability of the AMOC at different time scales. The natural and anthropogenic fluxes of heat, CO2 and N2O will be evaluated, as well as the present and submillenary scale transport of sediments and biogenic elements, and the impact of acidification on these timescales by means of the analysis of CaCO3 and organic carbon fluxes to the sediment. Besides, the current ocean acidification rates will also be quantified by evaluating the present situation and establishing future projections. These new observation-based estimates will be a valuable result that will be used to validate the predictions from the models (GCMs and ESMs from CMIP5-6) for the 2°C warming scenario. Finally, special attention will be paid to the rates of elevation of aragonite saturation horizons in deep layers, where the impact on the ecosystems sustained by calcareous organisms is potentially imminent.

Oceanographic data acquired during the FAR-DWO_DS1 Cruise (29SG20230719) on board the Research Vessel Sarmiento de Gamboa in 2023., In the FAR-DWO DS1 oceanographic cruise we analyze the hydrographic and sedimentological variability of the Denmark Strait Overflow using water column and seafloor observation and sampling techniques. We also deploy multi-instrumented mooring lines at depths between 1000 m and 2000 m to record information of the dense current during a whole year. The FAR-DWO DS1 cruise will last from July 19th to August 12th 2023 onboard the oceanographic vessel Sarmiento de Gamboa (CSIC). We are a team of around thirty experts from the Universitat de Barcelona (UB), Universidad de Las Palmas de Gran Canaria (ULPGC), Institut Français de Recherche pour l'Exploitation de la Mer (IFREMER), University of Iceland (UI), and the company specialized in satellite technology Lobelia Earth, and we count on the technical support of Unidad de Tecnología Marina (UTM-CSIC).

Oceanographic data acquired during the BOCATS-2-2023_LEG2 Cruise (29SG20230814) on board the Research Vessel Sarmiento de Gamboa in 2023., The ocean currently accumulates 93% of the excess heat and 31% of the excess CO2 generated by human activity. The AMOC influences the European climate in a very relevant way in that of the Iberian Peninsula and amplifies the capture of anthropogenic CO2 with an average rate that exceeds 50% of the average ocean value. Besides, in the subpolar gyre of the NA, ocean acidification reaches abyssal depths, endangering the future of ecosystems supported by cold water coral structures. The recent weakening of the AMOC has been noted and is expected to become more pronounced in the coming decades. The IPCC highlights the lack of observations to quantify the magnitude of this reduction. Therefore, observational monitoring (present and past) of ocean circulation and acidification in the NA is essential to advance the accurate detection of anthropogenic impact and improves the projections of the coupled climate models that support the IPCC reports for the subpolar gyre of NA. The paleoceanographic information from this area allows us to give context and establish the nature of previous changes to the instrumental records in different climatic contexts. BOCATS2 has as its main observational contribution the continuation of the biennial programme of oceanographic cruises in section A25-Ovide within the framework of the international GO-SHIP programme. Also, the new challenge of assessing the variability of the deep circulation of the NA will be faced, improving the spatiotemporal resolution of current currents by deploying the deep-ARGO array and at a submillenary scale using paleoceanographic data obtained in sedimentary records from key sites such as the Bight and Charlie-Gibbs fracture zones. The high-quality observations foreseen in the SPNA will contribute to the early detection of the alteration of the carbon cycle and will allow the precise estimation of the storage rates of heat, CO2 and N2O, connecting these changes to the variability of the AMOC at different time scales. The natural and anthropogenic fluxes of heat, CO2 and N2O will be evaluated, as well as the current and submillenary scale transport of sediments and biogenic elements and the impact of acidification on these scales through the analysis of CaCO3 and organic carbon fluxes to the sediment. Besides, the current ocean acidification rates will also be quantified evaluating the present situation and establishing future projections that will allow comparing the results of the observations with the predictions from the models for the 2°C warming scenario. Special attention will be paid to the elevation of aragonite saturation horizon in deep layers.
