Exploring the Depths of Loch Ness with Hydrophones

We caught up with Alan Mckenna from Loch Ness Exploration to find out why he is using the hydrophone to search the elusive monster…

The next tours with Alan Mckenna are on during The Quest Weekend.

When it comes to exploring the depths of Loch Ness, our options are limited by the loch’s incredible depth and the darkness that permeates its waters. It’s a place of mystery, with dangers that are unpredictable and a legend of a large, unknown creature possibly lurking below. While we rely on sonar and surface observations, the visibility in Loch Ness is extremely poor, making these methods challenging. So, what’s our next best option? Sound.

With the expertise of veteran and long-term investigator Dick Raynor, Loch Ness Exploration has embarked on a fascinating journey to listen to the world beneath the surface using trusted hydrophone equipment. A hydrophone is essentially an underwater microphone capable of detecting sounds hundreds of feet below the surface. Its sensitivity allows it to pick up sounds from miles away, including the faint hum of a boat traversing the loch.

Our goal is to record and catalogue as many underwater sounds as possible, identifying their sources and attempting to decipher what they might signify. This complex study aims to differentiate between natural sounds and those produced by human activities or man-made equipment. While identifying individual species by sound alone is a daunting task, we are particularly interested in the possibility of detecting an unknown creature, should it exist. Would it sound different? That’s a question we aim to
explore.

Every day at Loch Ness is unique, set against an ancient landscape rich in history. This research isn’t just about satisfying curiosity; it’s about providing valuable insight into one of the world’s most enduring mysteries. We are excited to continue this exploration and hope to uncover new aspects of the loch’s hidden depths.
