Preliminary deep-sea data analysis collected at Gloria seamount, Azores-Biscay ...
Tojeira, Inês; Pinto Ribeiro, Luísa; Rafael, Teresa; Albuquerque, Mónica; Simões, Maria; Calado, António; Afonso, Andreia; Ramos, Bruno; Souto, MiguelThe present study provides the first results of the exploratory research campaign to Gloria seamount (summit at 45.03°N, 15.54°W), a newly identified seamount in the NE Atlantic. New multibeam bathymetry and an 8 h remote operated vehicle footage and photography data were compiled and analyzed to give the first insights on the geological nature and benthic megafauna assemblages of Gloria seamount. Footage evide...

González, Javier; Somoza, Luis; Medialdea, Teresa; Santofimia, Ester; Rincón-Tomás, Bianca; Marques, Filipa; Pinto Ribeiro, Luísa; Calado, AntónioThe Moytirra hydrothermal vent field is located on the Mid-Atlantic Ridge (MAR) at approximately 45°N, between the Azores and Iceland. This system was discovered in 2011 during an Irish-led scientific expedition aboard the RV Celtic Explorer, and was later extensively explored and sampled in 2019 by the Spanish EXPLOSEA 2 expedition aboard the RV Sarmiento de Gamboa, with the support of the remotely operated ve...

Somoza, Luis; Medialdea, Teresa; González, Javier; Calado, António; Afonso, Andreia; Albuquerque, Mónica; Bettencourt, Renato; Blasco, IkerThis work presents the preliminary result of the multidisciplinary cruise EXPLOSEA2 surveying the northern Mid-Atlantic Ridge and Azores Archipelago from 46 300 N to 38 300 N aboard the R/V Sarmiento de Gamboa and ROV Luso over 54 days (June 11 to July 27, 2019). In this cruise report, we detail the geophysical, hydrographic, geological, oceanographic, ecological, and microbiological data acquired and a brief o...

Somoza, Luis; Medialdea, Teresa; González, Javier; Marchancoses, Sara; Candón, Jose; Cid, Constantino; Calado, António; Afonso, AndreiaThis work presents a new high-resolution multibeam bathymetric map of a segment of active deep sea-floor spreading in the Atlantic Ocean, the northern Mid-Atlantic Ridge (MAR) at 45–46º N. New high-resolution bathymetry data were acquired using an Atlas multibeam echosounder onboard the research vessel Sarmiento de Gamboa during the EXPLOSEA-2 survey in 2019. The final map of the MAR (50 m cell grid size) at th...
