  abstract = {{M}icroseismic activity, recorded everywhere on {E}arth, is largely due to ocean waves. {R}ecent progress has clearly identified sources of microseisms in the most energetic band, with periods from 3 to 10s. {I}n contrast, the generation of longer-period microseisms has been strongly debated. {T}wo mechanisms have been proposed to explain seismic wave generation: a primary mechanism, by which ocean waves propagating over bottom slopes generate seismic waves, and a secondary mechanism which relies on the nonlinear interaction of ocean waves. {H}ere we show that the primary mechanism explains the average power, frequency distribution, and most of the variability in signals recorded by vertical seismometers, for seismic periods ranging from 13 to 300s. {T}he secondary mechanism only explains seismic motions with periods shorter than 13s. {O}ur results build on a quantitative numerical model that gives access to time-varying maps of seismic noise sources.},
