Map benthic communities inhabiting unexplored areas around the Azores, identify new areas that fit the FAO VME definition; and determine distribution patterns of deep-sea benthic biodiversity. Dates TBC.

Mapping vertical walls and island slopes around the Azores with a submersible

Short mission dedicated to the maintenance of the EMSO-Azores observatory at Lucky Strike, Mid-Atlantic Ridge, a non-cabled multidisciplinary observatory devoted to the long term integrated study of mid-ocean ridge processes, from the subsea floor to the water column.

The MoMARSAT 2020 oceanographic campaign is jointly carried out by Ifremer and the Institut de Physique du Globe de Paris (IPGP-CNRS / INSU). This cruise is part of a long series that started in 2010 with the deployment of the EMSO-Azores observatory at the Lucky Strike vent field located within the Azores Marine Protected Areas. Every year since then, a maintenance cruise to the site is carried out to ensure the good functioning of the observatory: the two sea monitoring nodes (seamon) are brought up to the surface where the engineering team download large volumes of data from the instruments, which are then cleaned, checked, repaired if needed, and set-up for another year of observations.

Mooring recovery and re-deployment in the Iceland Basin and Rockall Trough, including the OSNAP array in the Iceland Basin and the Ellett array in Rockall Trough. Work will include hydrography, water chemistry and mooring maintenance. Scope of cruise reduced due to COVID-19 restrictions.

Postponed due to COVID-19 – awaiting further information on rescheduling

The primary purpose of this cruise is to service the Porcupine Abyssal Plain observatory, take biological samples and carry out benthic surveying

iMirabilis Logo

Named after the long-lived Welwitschia mirabilis plant of western Africa, the iMirabilis expedition is one of the flagship “Demonstrator Capacity Building cruises” of the iAtlantic project. The cruise will take place on the Spanish Research Vessel Sarmiento de Gamboa (SdG) from July to August 2021. The expedition was postponed from 2020 due to the Covid-19 situation, hence we re-named the new expedition as iMirabilis_2

The ship will travel from Vigo (Spain) to Last Palmas (Canaries, Spain), and from there will move to Cabo Verde waters to carry out the main research work. The transit between Vigo and Las Palmas will also be used for different training and capacity building activities. The expedition will finish in Las Palmas (Canaries, Spain).

iMirabilis_2 is an international multidisciplinary expedition with activities contributing to many tasks across iAtlantic’s work packages. At-sea activities will study both the water column (e.g. measuring oceanographic parameters, water and plankton sampling) and the seafloor. iMirabilis_2 mobilises state-of-the-art seabed survey equipment including the Autonomous Underwater Vehicle (AUV) Autosub6000 (from NOC) and the Remotely Operated Vehicle (ROV) Luso (from EMEPC). 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 in Cabo Verde. Moreover, the ROV Luso will allow collection of selected specimens for taxonomic purposes and for dating. Furthermore, new technologies will be tested during iMirabilis_2 including the eDNA ‘RoCSI’ sampler recently developed by researchers from National Oceanography Centre (NOC). Seabed lander equipment will also be deployed during iMirabilis_2 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.

Beyond the pure research activities, iMirabilis_2 includes detailed training and capacity building components, for instance, young researchers from South Africa and Cabo Verde will join the transit from Vigo to Las Palmas to be trained in the use of the ROV and in seabird identification and seabird census techniques. Furthermore, during the expedition, students from South Africa Brazil and Portugal will be on board to be trained in the use of the different gears as well as to learn how a research expedition is organized and led at sea. Besides this, outreach activities are planned during harbor visits at the beginning and end of the expedition as well as on board during the cruise.

The aim is to re-visit the Darwin Mounds and NW Rockall Bank MPAs and assess their status and the status of the cold-water corals, to test a new stereocamera system for the Autosub6000 AUV(BIOCAM) and to collect water column profiles on the Rockall margin. For iAtlantic we will collect additional box cores for macrofauna study (timeseries). Gear: AUV, HyBIS video platform, boxcore, megacore, CTD, mooring deployments.
