The Daily Mail reprises Marcus Atkinson's sonar hit from last year (see link). The interesting piece is a claim by a Simon Boxall of the National Oceanography Centre in Southampton that the trace shows a bloom of algae and zooplankton on the thermocline (the boundary between cold and warmer water layers).
However, I find that explanation a bit unconvincing due to the peaty nature of the loch. Algae need sunlight to photosynthesize and at a depth of 75 feet the loch has essentially become dark. Dick Raynor, who has dived at the loch says at his website that at about 70 feet all light would be lost from the surface when diving.
So, basically, no algae at 75 feet, certainly not enough "in bloom" to register on sonar. Mr. Boxall should think "Loch Ness" and not "English Channel"!
The Sun is also running the story here. Not sure why this is being rerun - it was all publicised back in September.
