According to the plan on his website, he'll be joined by researchers from Scotland, Europe and the United States, representing several universities between them, and rely on what Reuters calls a "well established tool for monitoring marine life", known as environmental DNA.
An worldwide team of scientists from the UK, Denmark, USA, Australia and France are planning to submerge themselves in the murky waters of Scotland's most mysterious freshwater loch.
If there is indeed a "monster" in Loch Ness, its DNA may show up as a type not found in the other three lochs.
The team will collect tiny fragments of skin and scales for two weeks in June.
The University of the Highlands and Islands' UHI Rivers and Lochs Institute in Inverness is assisting in the project.
All of the samples will then be sent off to laboratories in Denmark, France, New Zealand, the USA and Australia - the sources of the samples will be masked, so the lab techs won't know which samples come from which loch.
"In our lives we want there still to be mysteries, some of which we will ultimately solve", Gemmell said. And that's very exciting. "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 UK's largest freshwater body".
Although if there is a monster, surely there won't be any pre-existing monster DNA in the DNA databases to create a match, so. a free holiday and some social media content for professor Gemmell is the most likely outcome of 2018's Nessie hunt.
"You can't help but wonder, when so many swear black and blue that they saw these things, that there might be a biological basis for them", Gemmell said in a video earlier this year, as he prepared for the expedition.
Mr Campbell's report described a whale-like creature and the loch's water "cascading and churning".
For hundreds of years, visitors to Scotland's Loch Ness have described seeing a monster that some believe lurks in the depths.
Over the years various efforts have tried and failed to find the beast.
In popular culture, the Loch Ness Monster has reared its head many times, including in 1975's four-part Doctor Who - Terror of the Zygons, the 1980s cartoon The Family-Ness as well as The Simpsons and 1996's Loch Ness starring Ted Danson.
Sightings of the supposed Loch Ness Monster, which some claim to be a descendent of the plesiosaur whose lineage has survived in the isolate loch, have been ongoing since the sixth century. Last year, the BBC reported that purported sightings hit a record high.
