The ESME Workbench <http://esme.bu.edu> project will be at the 20th Biennial Conference on Marine Mammals, in Dunedin New Zealand, from 08 - 13 December.
The Effects of Sound on the Marine Environment (ESME) Workbench is a modeling environment that simulates the impact of anthropogenic noise on marine mammals. Narrow-band sound propagation is modeled using the Bellhop or RAMGeo. Realistic acoustic environmental parameters for bathymetry, water temperature and salinity, surface wind speed, and bottom sediment are provided via the Oceanographic and Atmospheric Master Library (OAML) databases. Sound sources have user-configurable source levels, frequencies, beam patterns, and movement models. The Marine Mammal Movement and Behavior (3MB) model provides simulated animal populations (animats) with 18 pre-configured behavior models for species with characterized dive behavior. Scenarios of moving sound sources and animats are simulated; sound exposure levels, positions, and timing information for each animat, and position and timing for each sound source are plotted and stored for custom analysis. We will be running an informal demonstration of the latest version of ESME and q&a session on Wednesday, 11 December, during the midday break between sessions. Specific location to be determined; please email [email protected] the latest information. -- Graham Voysey Boston University College of Engineering HRC Research Engineer Auditory Biophysics and Simulation Laboratory ERB 413
