A paper in the pre-press stages presents evidence of an acoustic anomaly in Lake Champlain, home to the legendary “Champ” lake monster.
Echolocation in a fresh water lake. | Browse – Journal of the Acoustical Society of America.
In 2003, 2005 and 2009 sites on Lake Champlain were explored using computers with National Instruments Polynesia real‐time sound analysis, NI PCMCIA 6062‐E cards, DAT recorders, GPS, amplifiers, three vector sensors, two hydrophones, and a Nagra IV‐S5. ECHO Aquarium in Vermont facilitated recording of known lake inhabitants and non‐biological signals studied formed the basis for the control. Neither recordings nor literature indicate that the known native creatures echolocate. Combining wavelet applications, aiding in reduction in ambient noise in this opposing environment along with conventional analysis, the experiments have been able to conduct far reaching, low‐noise sound measurements and were capable of detecting signals the nature of which suggests the presence of some interesting and unexpected phenomena within the ranges and inherent structure of Beluga whale, killer whale, and dolphin echolocation. To protect Lake Champlain, further investigations into this acoustic anomaly is encouraged.

Scott Says the paper should be published in this same journal next year. Very interesting! It does not mean we jump to the conclusion that this is Champ but this is the sort of evidence needed and procedure followed to get scientific attention. There is an anomaly, let’s go see what it is.
