EIMPACT-1 CRUISE, RV SARMIENTO DE GAMBOA

  • Arístegui, Javier
  • CSIC - Unidad de Tecnología Marina (UTM)
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.

BLUEHARVESTING CRUISE, RV SARMIENTO DE GAMBOA

  • Albert, Palanques
  • CSIC - Unidad de Tecnología Marina (UTM)
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.

  • Perea Manera, Hector
  • CSIC - Unidad de Tecnología Marina (UTM)
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.

BOCATS-2-2023_LEG1 CRUISE R/V SARMIENTO DE GAMBOA

  • Luciano Velo Lanchas, Antonio
  • CSIC - Unidad de Tecnología Marina (UTM)
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.

BOCATS-2-2023_LEG2 CRUISE, RV SARMIENTO DE GAMBOA

  • Francés, Guillermo
  • CSIC - Unidad de Tecnología Marina (UTM)
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.
