Description
Summary:Oceanographic data acquired during the iMIRABILIS-2_LEG1 Cruise (29SG20210731) on board the Research Vessel Sarmiento de Gamboa in 2021. iMIRABILIS-2 is an international multidisciplinary expedition with activities contributing to many tasks across iAtlantic’s workpackages. At sea activities will include the study of both the water column and the seafloor. iMIRABILIS-2 mobilises state-of-the-art seabed survey equipment including the Autonomous Underwater vehicle (AUV) Autosub6000 and the Remotely Operated Vehicle (ROV) Luso. This advanced technology allows iAtlantic to explore benthic ecosystems in great detail producing large high-resolution photographic results that will be processed automatically using new machine learning approaches. The results of these surveys will be used to produce high resolution habitat maps off Cabo Verde from which scarce information is currently available. Moreover, the ROV Luso will allow collection of selected specimens for taxonomic purposes and for dating. Furthermore, new technologies will be tested during the cruise including the eDNA ‘RoCSI’ sampler recently developed by researchers from the National Oceanography Centre (NOC, UK). Seabed lander equipment will also be deployed to obtain in situ information on environmental parameters and demersal deep-sea fish fauna. Ex situ experimental work will also take place on the ship, including short-term aquaria experiments with specimens collected with the ROV and incubations of sediment cores, collected by multicore.
