  abstract = {{W}e present methods of data analysis adapted to {M}obile {E}arthquake {R}ecorder in {M}arine {A}reas by {I}ndependent {D}ivers ({MERMAID}) seismograms, obtained with hydrophones mounted on moving underwater floats. {I}f the {MERMAID} float comes immediately to the surface after recording an earthquake signal, the seismogram location is obtained from the first {G}lobal {P}ositioning {S}ystem ({GPS}) position, using a correction for the surface drift of the float. {I}n the case of earthquakes recorded without an immediate surfacing, the location is estimated using a linear interpolation between {GPS} positions. {W}e performed a {B}ezier interpolation of the {GPS} positions to estimate a location error. {I}n 67% of the cases, the distance between the two trajectories was less than 500 m. {W}e tested the method on six months of data acquired in the {L}igurian basin ({M}editerranean {S}ea). {T}o validate the (manually) picked onset times for {P} waves, we performed a preliminary tomographic inversion beneath the {L}igurian basin of {MERMAID} data together with a much larger volume of picks from nearby land and ocean-bottom seismometer stations. {A}fter inversion we found that 67% of {MERMAID} data have a misfit between +/- 0:17 s, but the distribution of misfits is not {G}aussian and shows outliers. {W}e conclude that floating seismometers are an excellent and accurate means for covering oceanic areas for {P}-wave tomography.},
