00:00:00.010 --> 00:00:08.080
You could say Kyle Krabill is fond of his four-wheeler. But that's not what made him

2
00:00:08.100 --> 00:00:16.150
carefully pack it for travel, outfit it with specialized equipment like a GPS tracker, and bring it along

3
00:00:16.170 --> 00:00:24.220
on a 10,000 mile trip from his home in Virginia to the frozen continent of Antarctica.

4
00:00:24.240 --> 00:00:32.250
Twice a year, Kyle takes part in a NASA mission called Operation IceBridge. He and he colleagues Robbie and John

5
00:00:32.270 --> 00:00:36.320
travel to both poles to measure our planet's changing ice with the use of lasers

6
00:00:36.340 --> 00:00:44.380
mounted on aircraft. But to make sure that data is accurate, the entire mission relies on precise calibration

7
00:00:44.400 --> 00:00:48.460
basically they need to know exactly where the ground is.

8
00:00:48.480 --> 00:00:56.510
Usually, they both set up ground stations and also drive around on a level surface, like a runway, to get a reference

9
00:00:56.530 --> 00:01:00.560
map of a known elevation. But for the first time last fall,

10
00:01:00.580 --> 00:01:08.610
IceBridge was flying out of McMurdo Station in Antarctica, a place with not much bare earth. And the runway? A floating

11
00:01:08.630 --> 00:01:16.690
sheet of ice in McMurdo sound, which moves up and down with the tides every day. The solution? A trip to nearby

12
00:01:16.710 --> 00:01:20.730
Black Island. Kyle Krabill: The reason it's named Black Island is because the wind blows

13
00:01:20.750 --> 00:01:24.780
so hard, all the time, it blows the snow off. It's good for us because

14
00:01:24.800 --> 00:01:28.800
we want to, measure, the actual dirt, on the island.

15
00:01:28.820 --> 00:01:32.830
The road that goes down it, bad for us because it's a very tough

16
00:01:32.850 --> 00:01:36.850
place to get to and do some work. Narrator: The plan: wait for a

17
00:01:36.870 --> 00:01:40.870
calm enough day for the McMurdo helicopter squad to be able to ferry the

18
00:01:40.890 --> 00:01:44.890
ATV over to the island, followed by Kyle, Robbie, and John.

19
00:01:48.970 --> 00:01:57.060
On the first attempt, they only made it halfway there.

20
00:02:05.170 --> 00:02:13.210
But finally, the four-wheeler made the trip, followed by the crew.

21
00:02:25.320 --> 00:02:33.410
Kyle Krabill: For this the entire thing was different than we've ever done It wasn't an easy thing. Any time you

22
00:02:33.430 --> 00:02:41.490
deal with helicopter operations and a place where the wind can blow up to 160 miles an hour, it's a tough place

23
00:02:41.510 --> 00:02:45.520
to work, it's a tough environment to work in.

24
00:02:49.580 --> 00:02:57.630
The adventure was really fun. It was something different, and the day ended up looking really clean, and it worked well.

25
00:03:01.690 --> 00:03:05.730
Narrator: A job well done, it was time to ferry the ATV back to McMurdo,

26
00:03:05.750 --> 00:03:09.750
and when the campaign was over, return 10,000 miles to the

27
00:03:09.770 --> 00:03:17.840
Eastern Shore of Virginia, where Kyle and his four-wheeler would have quite a story to tell.
