During summer 2017 two surveys have been carried out on board of Daedalus targeting the ROV exploration of Ligurian seamounts by means of Multipluto. Departing harbour was La Spezia. A total of five seamounts (Ulisse, Penelope, Janua, S. Lucia, Occhiali) have been explored for a total of 17 dives carried out between 135 and 875m depth. For each mount ROV explorations aimed at characterizing the communities thriving on the tops. Oceanographic probes for temperature and salinity were deployed attached to the ROV. A total of 25 samples have been collected for both taxonomic and genetic analyses carried out by UNIGE and UNIBO. On-board of Daedalus were always present the captain Guido Gay (AzioneMare), PI Marzia Bo and post-doc SIR Martina Coppari, post-doc Francesco Massa. Each ROV exploration was preceded by a topographic description by means of Side Scan Sonar in order to localize the hard-bottoms where to direct the ROV surveys accounting for a total of 20 hours of video material.
