Global seismographic networks (GSNs) emerged during the late nineteenth and early
twentieth centuries, facilitated by seminal international developments in theory, technology …

The last decade witnessed an explosion in yearly number of publications on passive glacier
seismology. The seismic signals from a wide range of glacier‐related processes fill a broad …

Marine ecosystems are under increasing anthropogenic pressures from marine and
terrestrial activities. Ship traffic, the major cause of change in the open ocean, and its …

Spring 2018| Acoustics Today| 27 composed of contributions (Figure 2) from human activity
(eg, shipping, fishing vessels, seismic airgun surveys), natural abiotic or geophysical …

Accumulating evidence suggests that glacier basal motion can produce seismogenic stick‐
slip events caused by frictional resistance at the ice‐bed interface. Frequent and subsequent …

In late 2007, two massive icebergs, C19a and B15a, drifted into open water and slowly
disintegrated in the southernmost Pacific Ocean. Archived acoustic records show that the …

Measurements of underwater sound are still scarce in the rapidly changing Arctic. Tele-
seismically detectable glacial earthquakes caused by iceberg calving have been known for …

Arrays of hydrophones were deployed within the Bransfield Strait and Scotia Sea (Antarctic
Peninsula region) from 2005 to 2009 to record ambient ocean sound at frequencies of up to …

Passive acoustic monitoring takes advantage of the relative opacity of the ocean to sound.
Traditionally, long-term monitoring has employed archival instruments from which data are …

Although the size-frequency distributions of icebergs can provide insight into how they
disintegrate, our understanding of this process is incomplete. Fundamentally, there is a …
