Record #93908:

Speculations on the origin of low frequency Arctic Ocean noise / Ira Dyer.

Title: Speculations on the origin of low frequency Arctic Ocean noise / Ira Dyer.
Author(s): Dyer, Ira.
Date: 1988.
Publisher: Dordrecht: Kluwer Academic Publishers
In: Sea surface sound; natural mechanisms of surface generated noise in the ocean. (1988.),
Abstract: Summarizes earlier work, which shows that low-frequency noise, on average, correlates well with environmental moments and forces acting on sea ice, and that individual noise events can be aggregated over entire Arctic basin to yield average noise. Moments and forces are thus reasoned to relate directly to individual ice-source mechanisms. Models of sea-ice motion are proposed as noise sources. Ice cracking and transient unloading at ridges in response to moments, and ice-block creation and oscillation at overthrusting site in response to horizontal forces, are shown to be plausible. Models predict right order of stress in ice, radiation in proper frequency range, event signatures such as observed, and observed source strengths.
