LONDON (AP) — Mystery hunters have converged on a Scottish lake to look for signs of the mythical Loch Ness Monster. Researchers will seek evidence of Nessie using thermal-imaging drones, infrared cameras and a hydrophone to detect underwater sounds. The two-day event is being billed as the biggest survey of the lake for 50 years. It includes people from around the world watching remotely on webcams. Alan McKenna of the Loch Ness Center says the aim is “to inspire a new generation of Loch Ness enthusiasts.” Numerous theories have been put forward to explain monster sightings, including a prehistoric marine reptile, giant eels or an escaped circus elephant. Many believe the sightings are hoaxes or can be explained by floating logs or strong winds.
