French cave diver Frederic Swierczynski has become the first person in the world to dive to the bottom of Red Lake in Imotski on Saturday.
Swierczynski touched the bottom on the Red Lake at a depth of 245 metres in a dive that took around 4 hours to complete.
Situated in the Dalmatian Hinterland on the northern side of Biokovo, Red Lake is a sinkhole containing a karst lake and is known for its numerous caves and remarkably high cliffs, reaching over 241 metres above normal water level and continuing below the water level. Red Lake is the third largest sinkhole in the world.
“I am happy that I successfully completed the dive. It was a very interesting experience. It was cold and visibility was not good. In the end, everything worked out fine, I feel excellent”, Swierczynski said after the dive.
Over the past few days, the scientific part of the team who arrived for the history-making dive had set up 16 peaks, longlines, and nets at different depths. The goal was to determine which organisms live in the Red Lake and at various depths. Also, samples of sediment, sponges, and water were taken to analysis.
