  abstract = {{W}e propose a new probabilistic scheme for the automatic recognition of underwater acoustic signals generated by teleseismic {P}-waves recorded by hydrophones in the ocean. {T}he recognition of a given signal is based on the relative distribution of its power among different frequency bands. {T}he signal's power distribution is compared with a statistical model developed by analyzing relative power distributions of many signals of the same origin and a numerical criterion is calculated, which can serve as a measure of the probability for the signal to belong to the statistical model. {O}ur recognition scheme was applied to 6-month-long continuous records of seven ocean bottom hydrophones ({OBH}) deployed in the {L}igurian {S}ea. {A} maximum of 94% of all detectable teleseismic {P}-waves recorded during the deployment of the {OBH}s were recognized correctly with no false recognitions. {T}he proposed recognition method will be implemented in autonomous underwater robots dedicated to detect and transmit acoustic signals generated by teleseismic {P}-waves. {C}itation: {S}ukhovich, {A}., {J}.-{O}. {I}risson, {F}. {J}. {S}imons, {A}. {O}ge, {Y}. {H}ello, {A}. {D}eschamps, and {G}. {N}olet (2011), {A}utomatic discrimination of underwater acoustic signals generated by teleseismic {P}-waves: {A} probabilistic approach, {G}eophys. {R}es. {L}ett., 38, {L}18605, doi:10.1029/2011{GL}048474.},
