Biological Time Scales in Acoustic Backscatter from Littoral Bottom Boundary Layers

Abstract

We used time-series analysis with data from acoustic instruments, i.e., TAPS (Tracor Acoustic Profiling System) and BAMS and XBAMS (two versions of APL-UW's bottom-mounted sonar system) from several different localities. We supplemented acoustic data with trap samples and plankton tows timed to capture specimens to allow us to identify causes of acoustic events. In addition, we characterized bacterial and biopolymer coverage of sediments because of the potential effects of these viscoelastic materials on frictional loss between grains.
