Matsumoto, H., D.R. Bohnenstiehl, R.P. Dziak, L. Williams, R. Gliege, C. Meinig, and P. Harben (2010): A vertical hydrophone array coupled via inductive modem for detecting deep-ocean seismic and volcanic sources. In Oceans 2010 MTS/IEEE Seattle, Washington State Convention and Trade Center, Seattle, WA, 20–23 September, 2010.
A vertical autonomous hydrophone (VAUH) array useful for a long-term low-frequency underwater acoustic propagation study was developed at Oregon State University (OSU), North Carolina State University and the National Oceanic and Atmospheric Administration's (NOAA) Pacific Environmental Lab (PMEL). To analyze the arrival structure of the hydroacoustic signals in deep water, we needed a multichannel vertical hydrophone array with relative timing accuracy of as good as 10 ms/year where no GPS or Network Time Protocol (NTP) is available. A new scheme takes advantage of Inductive Modem Modules... more »
