He predicts they will document new species of life, particularly bacteria, and provide important data on the extent of several new invasive species recently seen in the loch, such as Pacific pink salmon. This time they'll comb the water for environmental DNA, which they hope will give them a yea or nay as to whether there is any truth behind the existence of the Loch Ness Monster.
Gemmell's team will be gathering little bits of DNA shed into the water from the fur, skin, scales, poop and urine of animals.
This is the prop Nessie that appeared in The Private Life of Sherlock Holmes.
"Large fish, like catfish and sturgeons, have been suggested as possible explanations for the monster myth, and we can very much test that idea and others", he said in a statement.
Gemmell is no believer but is ready to take people on this adventure and discuss some science on the way.
"While the prospect of looking for evidence of the Loch Ness monster is the hook to this project, there is an extraordinary amount of new knowledge that we will gain from the work about organisms that inhabit Loch Ness, the U.K.'s largest freshwater body", Gemmell said.
Stories about the lake concealing a monster date to the seventh century.
He said it would be possible to identify these plants and animals by comparing the sequences of their DNA against sequences held on a large, worldwide database. Adomnán's Life of St Columba tells of the saint encountering "a water beast". The nearby village of Drumnadrochit is home to two permanent Loch Ness monster exhibitions.
The development of photography sparked wider interest in the legend, and photographs taken in 1933 and 1934 featured on the front pages of national newspapers.
Over the years various efforts have tried and failed to find the beast.
Countless unsuccessful attempts to track down the monster have been made, notably in 2003 when the BBC funded a search that used 600 sonar beams and satellite tracking to sweep the full length of the loch. The team had speculated that a plesiosaur, a species that became extinct with the dinosaurs, may have survived in the chilly loch, despite the preference of marine reptiles for subtropical waters.
The new study's findings are expected to be presented in January.
