Description and Field Evaluation of the Broad-Band Underwater Recording Buoy System

Abstract

This report documents the design and features of a new four-element broad-band underwater recording buoy system. These buoys named the Broad-band Underwater Recording Buoys (BURBs) were built to facilitate medium-frequency underwater acoustic transmission experiments and for measurement of moving vessel acoustic signatures. Each BURB supports two wide-band hydrophones digitized with 16-bit resolution at 40,000 samples per second each and recorded onto internal hard-drive. Each BURB records its differential GPS position at 1 s intervals. Total operational duration is in excess of 36 hours of continuous operation. In an alternate configuration each BURB can acquire four-channel data from a new 3-axis acoustic intensity sensor. This report presents details on the BURB design construction acoustic calibrntion and operation. Example results from acceptance sea-trials conducted in March and April 2005 are presented.
