Hundreds of hopeful volunteers joined a two-day hunt for Scotland's fabled Loch Ness monster on Saturday and Sunday, in what organizers described as the biggest search for the elusive "Nessie" in more than 50 years.
The Loch Ness Center, which partnered with voluntary research team Loch Ness Exploration to organize "The Quest", said they would be using surveying equipment that had not previously been tried at the loch, including thermal drones.
Volunteers from around the world were allocated locations around the 23-mile (37-km) long lake from which to monitor for any signs of Nessie, while others took to boats. A hydrophone was also used to detect acoustic signals under the water.
"We did hear something. We heard four distinctive 'gloops'," said search leader Alan McKenna. "We all got a bit excited, ran to go make sure the recorder was on and it wasn’t plugged in."
The first written record of a monster relates to the Irish monk St Columba, who is said to have banished a "water beast" to the depths of the River Ness in the 6th century.
The most famous picture of Nessie, from 1934, showed a head on a long neck emerging from the water, but 60 years later it was revealed to have been a hoax that used a sea monster model attached to a toy submarine.
Countless unsuccessful attempts to track down the monster have been made in the years since.
