WEBVTT FILE 1 00:00:00.010 --> 00:00:04.040 You could say Kyle 2 00:00:04.060 --> 00:00:08.080 Krabill is fond of his four-wheeler. But that's not what made him 3 00:00:08.100 --> 00:00:12.140 carefully pack it for travel, outfit it with specialized equipment 4 00:00:12.160 --> 00:00:16.150 like a GPS tracker, and bring it along 5 00:00:16.170 --> 00:00:20.170 on a 10,000 mile trip from his home in Virginia to the frozen 6 00:00:20.190 --> 00:00:24.220 continent of Antarctica. 7 00:00:24.240 --> 00:00:28.240 Twice a year, Kyle takes part in a NASA mission called 8 00:00:28.260 --> 00:00:32.250 Operation IceBridge. He and he colleagues Robbie and John 9 00:00:32.270 --> 00:00:36.320 travel to both poles to measure our planet's changing ice with the use of lasers 10 00:00:36.340 --> 00:00:40.340 mounted on aircraft. But to make sure that data is accurate, 11 00:00:40.360 --> 00:00:44.380 the entire mission relies on precise calibration 12 00:00:44.400 --> 00:00:48.460 basically they need to know exactly where the ground is. 13 00:00:48.480 --> 00:00:52.470 Usually, they both set up ground stations 14 00:00:52.490 --> 00:00:56.510 and also drive around on a level surface, like a runway, to get a reference 15 00:00:56.530 --> 00:01:00.560 map of a known elevation. But for the first time last fall, 16 00:01:00.580 --> 00:01:04.580 IceBridge was flying out of McMurdo Station in Antarctica, a place 17 00:01:04.600 --> 00:01:08.610 with not much bare earth. And the runway? A floating 18 00:01:08.630 --> 00:01:12.670 sheet of ice in McMurdo sound, which moves up and down with the tides 19 00:01:12.690 --> 00:01:16.690 every day. The solution? A trip to nearby 20 00:01:16.710 --> 00:01:20.730 Black Island. Kyle Krabill: The reason it's named Black Island is because the wind blows 21 00:01:20.750 --> 00:01:24.780 so hard, all the time, it blows the snow off. It's good for us because 22 00:01:24.800 --> 00:01:28.800 we want to, measure, the actual dirt, on the island. 23 00:01:28.820 --> 00:01:32.830 The road that goes down it, bad for us because it's a very tough 24 00:01:32.850 --> 00:01:36.850 place to get to and do some work. Narrator: The plan: wait for a 25 00:01:36.870 --> 00:01:40.870 calm enough day for the McMurdo helicopter squad to be able to ferry the 26 00:01:40.890 --> 00:01:44.890 ATV over to the island, followed by Kyle, Robbie, and John. 27 00:01:44.910 --> 00:01:48.950 (music) 28 00:01:48.970 --> 00:01:52.990 On the first attempt, 29 00:01:53.010 --> 00:01:57.060 they only made it halfway there. 30 00:01:57.080 --> 00:02:01.140 31 00:02:01.160 --> 00:02:05.150 32 00:02:05.170 --> 00:02:09.170 But finally, the four-wheeler made the trip, 33 00:02:09.190 --> 00:02:13.210 followed by the crew. 34 00:02:13.230 --> 00:02:17.270 (music) 35 00:02:17.290 --> 00:02:21.280 (music) 36 00:02:21.300 --> 00:02:25.300 (music) 37 00:02:25.320 --> 00:02:29.350 Kyle Krabill: For this the entire thing was different than we've ever done 38 00:02:29.370 --> 00:02:33.410 It wasn't an easy thing. Any time you 39 00:02:33.430 --> 00:02:37.450 deal with helicopter operations and a place where the wind can blow 40 00:02:37.470 --> 00:02:41.490 up to 160 miles an hour, it's a tough place 41 00:02:41.510 --> 00:02:45.520 to work, it's a tough environment to work in. 42 00:02:45.540 --> 00:02:49.560 (music) 43 00:02:49.580 --> 00:02:53.580 The adventure was really fun. It was something different, and the day ended up 44 00:02:53.600 --> 00:02:57.630 looking really clean, and it worked well. 45 00:02:57.650 --> 00:03:01.670 (music) 46 00:03:01.690 --> 00:03:05.730 Narrator: A job well done, it was time to ferry the ATV back to McMurdo, 47 00:03:05.750 --> 00:03:09.750 and when the campaign was over, return 10,000 miles to the 48 00:03:09.770 --> 00:03:13.790 Eastern Shore of Virginia, where Kyle and his four-wheeler would have quite a story 49 00:03:13.810 --> 00:03:17.840 to tell. 50 00:03:17.860 --> 00:03:21.870 (helicopter sounds) 51 00:03:21.890 --> 00:03:25.900 (helicopter sounds) 52 00:03:25.920 --> 00:03:29.960 (helicopter sounds) 53 00:03:29.980 --> 00:03:33.980 (helicopter sounds) 54 00:03:34.000 --> 00:03:38.020 (helicopter sounds) 55 00:03:38.040 --> 00:03:42.080 (helicopter sounds) 56 00:03:42.100 --> 00:03:46.110 (helicopter sounds) 57 00:03:46.130 --> 00:03:50.160 (helicopter sounds) 58 00:03:50.180 --> 00:03:54.240 (faint helicopter sounds) 59 00:03:54.260 --> 00:03:58.260 (beeping) 60 00:03:58.280 --> 00:03:59.186 (beeping)
