some of the world's scientists are studying climate change at the top of the world glacier. 3/4 of greenland is covered in ice. each year it loses more ice then it gains in snowfall. believed to contribute to the rise in sea levels and maybe worse. sharon alfonsi traveled to the arctic circle to see what the researchers have discovered. >> great to see you. >> yeah. >> reporter: who did you upstreet to get pupit to be put out here. >> the god. the god. >> keith nichols is an expert drilling in remote places. in terms of remote this would be

really hard to beat. feels like you are on another planet. >> can't take a walk around here. expecting scott yo to beam you up. it is extraordinary. >> reporter: nichols and scientists are drawn to this sliver of greenland in part by the satellite images. in 2010, a chunk of ice, four times the size of manhattan, broke off. then, two years later, another large chunk came down. the glacier has receded by 20 miles in five years. nichols and his team are trying to drill beneath it. >> this is a lot of work. difficult conditions. what do you hop to learn? >> what we are frying to leatry how the ocean is interacting with ice, momenting it. and in future how that might change. they heated melt water from the glacier to make a hot water drill to pierce through the 300 foot thick ice.

there has to be serious challenge to running equipment like this in this kind of weather? >> the biggest challenge we have got water. it is very cold. so if you have water freezing in hoses that can be devastating. it's for the projects. >> this is the moment the coring machine struck the bottom of the sea floor. a half mile beneath the ice, they made history. it was the first time any one has ever collected sediment from beneath the ice shelf in greenland. >> the ocean beneath is probably the least accessible part of the world ocean. and just getting access to that is a triumph frankly as far as we are concerned. the ice shelf extends from the glacier and fleoats on the ocea. they believe it acts like a dam, holding back ice from sliding into the sea. if it goes away, sea levels go up. is there a sense of urgency in the work that you are doing? >> the sea level rises, the big question we are trying to get

at. and peterman glacier, this experiment here, gives us an opportunity to get at the processes, and try to understand the basic physics to how that can happen. >> our visit to the ice camp was cut short. our pilots warned of something, ice fog moving in. and could strand us here for days. we high tailed it back to the helicopter. heading to another outpost of the expedition. what the scientists call boulder camp. set up on the j edge of peterma glacier. steve marquatt and geologists have been here for weeks gathering samples from rocks. >> this was probably deposited when the ice was maybe a few hundred to few thousand feet thicker. when deposited you are probably talking about, 600 feet of ice above us. >> above where we are now. >> above where we are now. peterman would have been much larger, dropping the rocks all over the surface.

>> to the person at home who is looking at you guys chipping at rocks why should i care about this? >> we know if you warm the planet up. glaciers respond. they melt. the question is at what rate? how fast its that going to that pen? where is if the going to happen? where are the vulnerable spots in the ice sheet. to understand all that you have to understand how the ice sheet, what controls an ice sheet. we need to understand this glacier to provide a better prediction for the ice sheet. that matters to us because of sea level. if the glaciers can respond die namingly, we should all be concerned. because the that can create dynamic changes in sea level and flood infrastructure. we need new know that planning for the future. >> reporter: we camped out next to the scientists. with 24 hours of light. we slept in the tents under the midnight sun. in the morning, we were shuttled out to meet the swedish ice breaker making its way around peterman glacier. it supports the scientists on land and acts as a fleeti ifloa

>> see the blocks of ice drifting by. >> reporter: allen mix is running the ship's coretion operation. trying to grab sediment from the sea floor. >> actually the coring site is under the block of ice. we just can't get there. we are trying to drift with the ice and sort of snook up on it. gently. >> reporter: it is hard to sneak up on anything in an ice breaker. he doesn't so much as sail, as it does smash the ice like a 13,000 ton hammer. once in position they throw a piston core, like a dart, at the bottom of the ocean. >> that doesn't sound good. >> after multiple attempts. >> go to the next up. hit it with a gravity core. >> a car sample look this is collected. inside the ship's lab, the multiyear process of investigating those cores, begins. what is your best guess. how old is this?

>> so the base of this core -- probably is no more than 10,000 years. >> reporter: ann jennings with institute of arctic and alpine research. she says each core holds clues about peterman glacier's past. >> we didn't really expect to find things living under the ice shelf. we have. >> what have you found? >> this one we found, sivisivides-storfi. >> easy for you to say. >> it is a seashell. single celled animal. >> reporter: the single celled animal like all living creatures made out of car been alug scientists to -- carbon, alug scientists to determine when they lived. take the depth scale here. convert it to age. then we can say when did the ice retreat? how quickly did it retreat? was there a lot of multiwalter coming out? >> you can get all of that from what looks like mud?

>> yes. >> reporter: after a week in greenland, we headed home. but the scientists kept working. taking advantage of the final days of the short arctic summer. the 66 core samples they collected during their month at sea will be studied by scientists around the world for decades. >> this is the largest core repository in the world. >> a paleo climatologist at columbia university. he says cores collected in greenland are like a black box of the earth's inner workings. this one he collected south of greenland. >> this is today's climate. we have had 10,000 years of roll tiffly warm climate. then we go, 10,000 years in the past. boom. there is the last ice age. this is when long island was formed. cape cod was formed. go on. just find this color. this is filled with these rocks. ice rafted treditis. this period. whoa, a warm phase.
