First Hole in North Pole Ice Drilled to Study Impacts of Climate Change

A group of Arctic explorers has made the grueling journey to the North Pole and drilled a hole in the ice to take the first ever sample of ocean water at the pole in an effort to better understand the impacts of climate change.

The explorers, part of a group called the Catlin Arctic Survey, completed the sampling expedition after failing to last year, reported the Guardian.

The team reached the geographic North Pole on May 12 after a 60-day trek across the frigid Arctic ice.

The explorers have been collecting water and marine life samples from beneath the floating sea ice during their expedition in an effort to understand how the acidification of the ocean — caused by the same accumulation of carbon dioxide in the atmosphere that is behind the planet's warming — is impacting the polar environment.

Ocean acidification occurs as the ocean absorbs excess carbon dioxide from the atmosphere, which makes the ocean more acidic and threatens organisms that have shells and skeletons made from certain minerals that dissolve in more acidic conditions, such as corals.

The team drilled their final hole of the mission (and the first hole at the North Pole) manually through the ice at the North Pole, capping off the 483-mile (777-kilometer) trek they have been on since March 14.

"We called it our Hole at the Pole," said former bank manager turned Arctic explorer Ann Daniels. "Getting the science work done has always been our top priority, but it is absolutely fantastic to reach the Pole as well. We're ecstatic."
