The geographical coordinates of each seamount peak position (summit-peak depth or shallower depth of the seamount structure) have been obtained from the EMODnet bathymetry as well as its base depth interval, which have been estimated on the basis of the deepest bathymetry ring encompassing the seamount structure. Depths have been done at 10m intervals. The list considers as seamount a wide set of undersea features with an elevation of at least 100m from the sea bottom, such as: banks, guyots, highs, hills, knolls, peaks, reefs, ridges, rises, spurs and volcanoes according to IHO standard names (mud volcanoes and features belonging to the continental shelf have been not included into the list, even if have an elevation of 100m or more). Mediterranean seamount list counts 194 of such structures with an official or shared name, which can be found in scientific literature or by searching on internet (i.e. sport fishing web sites, etc.). To this list it must be added from 50 to 100 unnamed seamounts, which have been identified on the basis of criteria described by Staudigel et al. (2010). The revision of this list is in progress. As seamounts have a great effect on general circulation and on productivity of the Mediterranean Sea, they all should be considered for conservation, even if a very poor information exist about many of them, mainly considering their benthic communities (i.e. Cold Water Coral communities distribution and consistence) as well as the assemblages of mesopelagic organisms (i.e. deep scattering layer DSL) and top predator concentration in their vicinity. Recent results from the Prometeos project confirm that the seamount effect on the distribution of the large pelagic predators, such as cetaceans, tunas, swordfishes, shark, birds and turtles, it may extend up to 15-20 NM from the seamount summit. This aspect should be considered in conservation measures. Seamounts are typically off shore structures, nevertheless many are located within few tens NMs from the coast and can be easily reached by professional and sport fishermen. Many have a summit between 50 and 1000m depth, thus can be easily exploited by common fishing gears. Such a seamounts host bentho-nektonic fauna of high commercial value: e.g. Atlantic pomfret (Brama brama), Backspot seabream (Pagellus bogaraveo), Wreckfish (Polyprion americanus), Blackfish (Centrolophus niger), Imperial blackfish (Schedophilus ovalis), etc. In some seamounts there is evidence of overexploitation of these species.
