The ambient seismic wave field, also known as ambient noise, is excited by oceanic gravity
waves primarily. This can be categorized as seismic hum (1–20 mHz), primary microseisms …

Distributed fiber-optic sensing technology coupled to existing subsea cables (dark fiber)
allows observation of ocean and solid earth phenomena. We used an optical fiber from the …

The increasing number of broad-band seismic stations recording the full spectrum of the
seismic wavefield continuously has boosted interest in background signals recorded in the …

Microseism is the continuous background seismic signal caused by the interaction between
the atmosphere, the hydrosphere and the solid Earth. Several studies have dealt with the …

Our knowledge of the origin of Love waves in the ambient seismic noise is extremely limited.
This applies in particular to constraints on source locations and source mechanisms for Love …

Secondary microseismic noise is generated by non-linear interactions between ocean
waves at the ocean surface. We present here the theory for computing the site effect of the …

Recent studies attribute land double‐frequency (DF) microseism observations to deep water
generation. Here we show that near‐coastal generation is generally the dominant source …

We analyze global microseism excitation patterns between July 2000 and June 2001.
Seismological observations are compared with modeling results to isolate robust activity …

We report for the first time on a distributed acoustic sensing (DAS) array using preexisting
underground fiber optics beneath the Penn State campus for detecting and characterizing …

Ocean waves incident on coasts generate seismic surface waves in three frequency bands
via three pathways: direct pressure on the seafloor (primary microseisms, PM), standing …
