ACSM is experienced in working together with scientists from diffe- rent backgrounds in offshore operations. Thanks to the services provided to the Spanish Institute of Oceanography, IEO, during many years we have successfully completed campaigns involving the use of ROVs together with oceanographical instrumentation: niskin bottles, ADCP, CTD, magnetometers, towed instruments, moorings, buoys and drifters, gliders, etc. The scientific missions that we have participated at include: archaeology, fisheries, subsea volcano activity, geophysical and geotechnical surveys, biology and environmental studies, marine zoology, physicochemical investigations, etc.
Some of these campaigns, have given a documentary as a result, using ACSM ROV and offshore expertise. Such is the case of Nuestra Señora de las Mercedes wreckage, a frigate from 1804, sank in the coast of Portugal, close to El Algarve at 1.10
0 to 1.200 msw.
The explosion of the subsea volcano in the island of El Hierro in the Canaries in 2011, was the first campaign for the Liropus 2000 Subatlantic ROV piloted by ACSM crew. Posterior campaigns in 2014 have permitted to collect what appeared to be iron oxide deposits, as well as bacterial ‘blankets’ and emissions of low-temperature fluid near the main crater.
ACSM ROV pilots participated in the scientific expedition to the wreck “Nuestra Señora de Las Mercedes”, carried out between August 18th and 23rd. ACSM pilot´s participated in this multidisciplinary team made up of personnel from the National Museum of Underwater Archeology ARQUA, from the Spanish Institute of Oceanography and from the Naval Museum of the Spanish Navy together with a filming team that produced a documentary. The operation was completed by the Liropus 2000 ROV at more than 1.000 meters deep, with one of ACSM´s titanium manipulators installed. The footage obtained by our pilots was used for the documentary.
