WEBVTT 00:00:41.798 --> 00:00:44.688 Chapter 1 View from the Etendard 00:01:01.125 --> 00:01:03.498 My name is Delphine Six and 00:01:03.498 --> 00:01:05.668 I'm a glaciologist at the Laboratory 00:01:05.668 --> 00:01:07.748 of Glaciology in Grenoble 00:01:07.748 --> 00:01:10.467 and we are here for 2 days with the POW team, 00:01:10.467 --> 00:01:12.827 to make the measurement campaign of the St Sorlin Glacier. 00:02:06.756 --> 00:02:11.296 So we came here with 2 glaciologists to help them for the measurement campaign of St Sorlin Glacier 00:02:11.296 --> 00:02:15.011 and spend 2 amazing days in the mountains around. 00:02:18.566 --> 00:02:22.394 So we are here on the St Sorlin Glacier for 2 days, in July, 00:02:22.394 --> 00:02:26.666 We measure it for more than 60 years to follow 00:02:26.686 --> 00:02:32.156 its evolution and how it answered to the climate change, 00:02:32.166 --> 00:02:37.488 and today we have a very particular year, because we are at the end of july, 00:02:37.488 --> 00:02:43.010 and all together we were able to touch the snow from the bottom to the top of the glacier, 00:02:43.020 --> 00:02:46.283 so it's a year with a lot of snow here, and that's very good for glaciers ! 00:02:58.508 --> 00:03:01.231 We are at the first point, and we have 40 more to do ! 00:03:14.251 --> 00:03:19.255 What we did during these 2 days, is measuring the milestones which are set up into the glacier, 00:03:19.255 --> 00:03:25.329 and we have 40 milestones on this glacier, from the bottom to the top of it, next to the summit of the Pic de l'Etendard 00:03:25.329 --> 00:03:29.541 that our POW team climbed this morning at dusk ! 00:03:35.740 --> 00:03:38.684 We were very effective... 00:03:38.694 --> 00:03:44.662 The number 9 is slightly offset. It is more around here ? Yeah... 00:05:03.708 --> 00:05:07.952 It's so wild right, the Pic de l'Etendard ! 00:05:07.952 --> 00:05:11.789 Ok so we let you finish your work, because it seems you are working ! 00:05:11.789 --> 00:05:15.151 Yeah we are not in holidays ! 00:05:24.963 --> 00:05:31.841 At each milestone, we measure the emergence, the colour, and next we do a lot of calculation 00:05:31.841 --> 00:05:37.429 to understand the health of the glacier many time during the year and for 60 years now! 00:05:37.429 --> 00:05:42.315 We are at milestone 10, this is the highest on the glacier, 00:05:42.315 --> 00:05:50.825 and we have to check the colour, because there is several sticks of different colours attached to each others 00:05:50.825 --> 00:05:59.260 and after we will measure the emergence of the stick compare to the snow pack 00:05:59.260 --> 00:06:04.829 thanks to the probe that Coline already prepared... 00:06:04.829 --> 00:06:08.696 Right.... mhhhhh 00:06:09.095 --> 00:06:10.956 And what ?! 00:06:13.012 --> 00:06:14.766 First measure !! 00:06:15.458 --> 00:06:18.576 It's not complicated to be a glaciologist ! Right ? 00:06:20.906 --> 00:06:22.869 You should become one ! 00:06:22.869 --> 00:06:24.649 We will not tell them ! No no we are not ! 00:06:45.417 --> 00:06:49.576 The St Sorlin Glacier is not different than the other glaciers in the alps 00:06:49.576 --> 00:06:55.212 it is loosing volume, thickness and length. 00:06:55.212 --> 00:06:58.514 2015 was catastrophic for the glaciers 00:06:58.514 --> 00:07:04.727 but 2016 looks like a good year, it is still covert by snow. 00:07:04.727 --> 00:07:09.292 We had finally a winter with a lot of snow at these altitude 00:07:09.292 --> 00:07:14.950 which is very good for the glacier, like a reprieve for it. 00:07:19.565 --> 00:07:23.807 We try to understand here how the sun radiation, 00:07:23.807 --> 00:07:25.801 the atmosphère, the humidity, the wind 00:07:25.801 --> 00:07:27.486 are influencing the snow and ice melt 00:07:28.532 --> 00:07:31.278 Look a these rock at the bottom of the slope 00:07:31.278 --> 00:07:33.928 2 years ago they were not visible 00:07:35.336 --> 00:07:38.271 Same at the top on the ridge, 00:07:38.271 --> 00:07:43.695 in real summer without snow, there is a huge difference... 00:07:46.760 --> 00:07:51.231 So we checked 5 milestones, and them almost 40 ! 00:07:51.231 --> 00:07:55.641 It's was my first time in the mountain after my surgery 00:07:55.641 --> 00:08:01.545 and it really give another dimension, another approach to the mountain 00:08:01.545 --> 00:08:06.508 It's amazing to have another view on our environment, where we ride or climb usually 00:08:06.508 --> 00:08:13.376 In Freestyle skiing, it's not the most sustainable practice 00:08:13.376 --> 00:08:20.230 but I'd like more and more people to have this in mind, and act to reduce our impact 00:08:24.866 --> 00:08:28.351 If the climate change is getting worst, in 2050 it will be impossible to climb 00:08:28.351 --> 00:08:31.827 on the glacier of St Sorlin to reach the Pic de l'Etendard 00:08:31.827 --> 00:08:34.354 This glacier will have disappeared. 00:08:35.304 --> 00:08:39.276 It's pretty rare but 4 glaciologist girls in a team of 4, we beat some records ! 00:08:39.276 --> 00:08:42.369 and 2 very competent interns ! 00:08:42.369 --> 00:08:44.843 Yeah and we had a lot of fun !
