KILPISJÄRVI: As bubbles rippled across the frigid Finnish lake, diver Daan Jacobs emerged from a hole carved out of the thick, crackling ice.

The journey had taken him 8 meters (26 feet) beneath the surface, where sunlight filtered through the Arctic ice and fish swam around a rock formation. It’s a remote place few will ever see, especially in winter, when snow blankets the ice and temperatures on land approach minus 40 degrees in both Celsius and Fahrenheit.

But Jacobs, a biodiversity adviser in the Netherlands, is one of a growing number of fortunate underwater explorers.

He was part of the Polar Scientific Diving class in the far north of Finland earlier this month, a program designed by the Finnish Scientific Diving Academy to train the next generation of scientists and researchers to dive beneath the Arctic and Antarctic ice to study the flora and fauna below.

“The view is beautiful,” Jacobs said, gulping for air following his 45-minute dive.
