Adrian Shrine is the founder of The Loch Ness Project and one of the most influential researchers on the subject of the Loch Ness Monster. He has been leading expeditions and studies on the loch since 1973. His efforts have led to collaborations with over 20 universities and over 1,000 individuals that want to get to the bottom of the loch’s mystery. In 1987, he organized an expedition at an enormous scale called Operation Deepscan which was a sonar sweep of the entire loch. Shrine blames some sightings on the “psychology of human perception”; in which witnesses misidentify things like logs, waves, and dark patches of calm water as a monster.
