On 21 July Ayas Nautical Research Club and Armenian Extreme Ltd, set a world record in the Northern Hemisphere by submerging to the bottom of Lake Kari on Aragats Mountain, 3207m above sea level. ‘We stayed underwater for 1 hr. 20 min which was enough to study 70% of the lake bottom. During submersion the temperature was +5 C on the surface and +3 C in the lake bottom, it was very cold. 20 years ago the lake froze over, so the lake wasn’t rich in fauna; still, we discovered several species of fish,’ Mkrtchyan said.
