ULF/VLF Noise on Basalt and Sediment (NOBS).

Abstract

This experiment undertook a comparison between noise and seismic signal fields on seafloor of two different structural types. Arrays of newly constructed ONR OBS's were deployed on the flanks of the Gorda Ridge, Juan De Fuca Ridge, and in the Cascadia Basin. These instruments made simultaneous observations of seafloor noise, in addition to some earthquakes. The primary question addressed was 'Is seafloor noise smaller at hard-bottom (basalt) seafloor sites than it is at thickly-sedimented sites?'. The answer depends on the frequency.
