Every day scientists are taking a long, hard look at the Arctic areas of the world.

The PBS docuseries, 鈥淎ges of Ice,鈥� goes behind the scenes with these researchers, like Alun Hubbard, director of the Thule Institute at the University of Oulu in Finland, and professor at UiT The Arctic University of Norway.

Hubbard has spent three decades studying Greenland鈥檚 icy interior, cataloging the journey of an ice sheet that begins with a single snowflake.

Antarctica and Greenland hold two of the world鈥檚 great ice sheets, which reflect heat, store water and help keep the planet鈥檚 climate in balance.

鈥淲e鈥檙e just coming out of a very frigid, dark winter,鈥� Hubbard says. 鈥淒ays like today, I just wish I鈥檇 done tropical reefs. You can see, well, actually, it鈥檚 not a flat ice sheet. What we鈥檝e got behind us is a pretty impressive canyon, which carries a big, big melt river during the summer.鈥�

Northern Pictures created the docuseries, which combines epic adventure, frontline science and deeply human stories.

According to PBS, 鈥淎ges of Ice鈥� immerses viewers in places of staggering beauty and brutal extremes from the frozen Arctic Ocean to the high plateaus of Antarctica. Scientists explore the harshest frontiers on Earth and uncover the changes transforming the world. The series is narrated by Scottish actor David Tennant.

鈥淎ges of Ice鈥� will air at 9 p.m. Wednesday, Sept. 16, on New Mexico PBS, channel 5.1. The next two episodes will air at 9 p.m. Sept. 23 and Sept. 30, on channel 5.1. Each episode will be available to stream on the PBS app after broadcast.

A crack in the ice is where most would turn back, Hubbard says, but to understand what鈥檚 happening to the ice sheet, you have to step inside.

鈥淚t鈥檚 just such a sort of weird, surreal, creamy whip kind of ice skate. You couldn鈥檛 dream this up,鈥� Hubbard says.

Greenland鈥檚 ice sheet has endured for millions of years, but canyons are beginning to reveal how quickly it鈥檚 changing.

鈥淚t鈥檚 really lovely to get up close to the ice and see all the amazing detail, and then start to think, well, why is that looking like that? Why is that doing that? This really does, to me, show the absolute power of water in sculpting, sculpting this ice, and the effect and the impact it has on that ice. In a couple of months, there鈥檚 no way to be here,鈥� Hubbard says. 鈥淭his will be topped off, full of an absolute torrent of meltwater, with huge amounts of energy, huge amounts of power.鈥�

Hubbard says, each summer, the Greenland ice sheet sheds more than 250 billion tons of ice. In just three decades, the rate of ice loss has increased.

鈥淭he ice sheet has always melted,鈥� he says. 鈥淚f it didn鈥檛, it would take over the whole planet. But this ice sheet, which holds over seven meters of global sea level rise, that鈥檚 been taking a real hammering in the last two decades.鈥�

Meltwater rivers wind their way across the ice, only to disappear down deep shafts known as mirrors, draining into the depths below. Hubbard is monitoring the changes and believes that the sinkholes can unlock new clues to the accelerating change.

鈥淭he idea here is we鈥檙e going to put in a methane sensor to see what methane may be expelling out of the ice and from the bed. It鈥檚 only a hunch, but you have to try,鈥� he says. 鈥淚鈥檓 very confident. Bit nervous now, actually. Been thinking about it too much. Hopefully, I won鈥檛 be doing a Darwin Award today.鈥�
