  abstract = {{O}ur understanding of the internal dynamics of the {E}arth is largely based on images of seismic velocity variations in the mantle obtained with global tomography. {H}owever, our ability to image the mantle is severely hampered by a lack of seismic data collected in marine areas. {H}ere we report observations made under different noise conditions (in the {M}editerranean {S}ea, the {I}ndian and {P}acific {O}ceans) by a submarine floating seismograph, and show that such floats are able to fill the oceanic data gap. {D}epending on the ambient noise level, the floats can record between 35 and 63% of distant earthquakes with a moment magnitude {M} >= 6.5. {E}ven magnitudes <6.0 can be successfully observed under favourable noise conditions. {T}he serendipitous recording of an earthquake swarm near the {I}ndian {O}cean triple junction enabled us to establish a threshold magnitude between 2.7 and 3.4 for local earthquakes in the noisiest of the three environments.},
