Meet the Scientist: Lake ChamplainHome To A Mystery Animal? July 16, 2009

Bio-acoustician E. von Muggenthaler will discuss her research that led to the discovery of bio-sonar signals in Lake Champlain. Only dolphins and whales echolocate underwater, as a form of communication and as a food searching technique, and there are none in this Lake. What creature is making this high frequency sound?
