Vibrational Sensing in Benthic Invertebrates.

Abstract

This grant funded completion of a number of studies on the effects of fluid motion on small planktonic organisms. It documented the response of some benthic marine invertebrates to prolonged vibrational stimuli at 50-200 Hz, perhaps indicative of energetic, bottom boundary-layer turbulence. It showed that vibrational artifact and flow intensity generally covary in laboratory flumes used for behavioral studies of animals. Most importantly, data analyzed under this grant gave early indication that high-frequency (>/- 40 kHz) low-angle acoustic backscatter could give information on activities of benthic macrofauna at unprecedented spatial and temporal scales.
