Abstract:

The scientific objectives of this research were to perform coupling noise OBS field tests designed to provide quantitative estimates of the coupling distortion and excess noise to be expected from high quality newly designed OBSs to provide data required for transfer functions to compensate for the coupling distortion and to suggest further improvements in instrumentation design and deployment procedures. The specific objectives of this contract were to organize and conduct field test and analyses of the bottom coupling characteristics and excess noise of new and renovated ocean-bottom seismographs. This research was in support of the instrument development being conducted under the ONR Accelerated Research Initiative ARI on ULFVLF Ocean Seismo-acoustics. Research conducted under this contract included planning, preparation for, and conduct of the November field tests. Keywords Ocean-bottom seismographs, Bottom coupling OBS-excess noise, OBS operational field tests.
