Infragravity waves: From driving mechanisms to impacts
Infragravity (hereafter IG) waves are surface ocean waves with frequencies below those of
wind-generated “short waves”(typically below 0.04 Hz). Here we focus on the most common …

Broadband seismology and noise under the ocean
SC Webb - Reviews of Geophysics, 1998 - Wiley Online Library
Most of our understanding of the Earth's interior has been derived from measurements from
global seismic networks, although no network has ever been truly “global” because some …

Antarctic ice shelf disintegration triggered by sea ice loss and ocean swell
Understanding the causes of recent catastrophic ice shelf disintegrations is a crucial step
towards improving coupled models of the Antarctic Ice Sheet and predicting its future state …

A study of the seismic noise from its long‐range correlation properties
We study the origin of the background seismic noise averaged over long time by cross
correlating of the vertical component of motion, which were first normalized by 1‐bit coding …

Excitation of Earth's continuous free oscillations by atmosphere–ocean–seafloor coupling
J Rhie, B Romanowicz - Nature, 2004 - nature.com
The Earth undergoes continuous oscillations, and free oscillation peaks have been
consistently identified in seismic records in the frequency range 2–7 mHz (refs,), on days …

Infragravity-frequency (0.005–0.05 Hz) motions on the shelf. Part I: Forced waves
This is Part 1 of a two-part study of infragravity-frequency (nominally 0.005–0.05 Hz) motions
on the continental shelf. Data from a large aperture (250 m× 250 m) array of 24 bottom …

Ambient seismic wave field
K Nishida - Proceedings of the Japan Academy, Series B, 2017 - jstage.jst.go.jp
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 …

The Earth's 'hum'is driven by ocean waves over the continental shelves
SC Webb - Nature, 2007 - nature.com
Observations show that the seismic normal modes of the Earth at frequencies near 10 mHz
are excited at a nearly constant level in the absence of large earthquakes. This background …
