In the absence of earthquakes, oceanic microseisms are the strongest signals recorded by seismic stations. Using the GEOSCOPE global seismic network, we show that the secondary microseism spectra have global characteristics that depend not only on local characteristics but also on the station latitude and on the season. In both hemispheres, noise amplitude is larger during local winter, and close

Seismic studies of the last ten years in the Pyrenees (deep seismic profiles, fan profiles at critical distance, teleseismic travel-time residuals, seismicity from temporary networks) and their most significant results concerning crustal thickness in the different structural units of the range, sharpness of the transition between these units at depth, and east-west lateral evolution are reviewed in this paper.
