Beaufort Ambient Seismo-Acoustics Beneath Ice Cover (BASIC)

Abstract

In order to understand the processes controlling ultra low frequency ambient noise within the ocean, it is necessary to vary boundary conditions by examining seafloor noise under different atmospheric and sea conditions. Open ocean with gently sloping continental margin; steeply sloping margin; contrasted basaltic (hard) and sedimented (soft) rock bottom; and ocean entirely covered by sea ice all represent different controls upon noise generation and propagation. By carrying out a coordinated series of array experiments under such different conditions, the physical mechanisms of seafloor ambient noise will be better understood
