Sonar Image Shows Nessie… or Algae

Marcus Atkinson, skipper of a Loch Ness tourist boat, noticed something strange on his sonar fish finder: a long, snake-like object at a depth of 75 ft. (In the image, the green line to the left of the number 25.) So he quickly snapped a picture of the sonar screen with his mobile phone. The picture recently won him bookmaker William Hill's Best Nessie Sighting of The Year Award.

Of course, the scientists have to throw cold water on the excitement of all the Nessie fans. Dr Simon Boxall, of the National Oceanography Centre in Southampton, says:
The image shows a bloom of algae and zooplankton that would exist on what would be a thermocline. Zooplankton live off this algae and reflect sound signals from echo sounders and fish finders very well. They will appear as a linear “blob” on the screen, just like this. This is a monster made of millions of tiny animals and plants and represents the bulk of life in the Loch.

If *this* won him the sighting of the year award then their standards have really fallen. I've been to The Lake once (and so have many others on this site, I reckon, since I believe one of the forum reunions was organized there?) and as far as I can tell the tourist boat travels the lake a few times a day, at least. If that's the greatest sighting of the year...well...Scottland, I am dissapointed in you.
