WEBVTT FILE 1 00:00:00.000 --> 00:00:06.064 [Music] 2 00:00:06.064 --> 00:00:09.202 This year we're taking you to the dead places on the planet Earth. 3 00:00:09.202 --> 00:00:17.552 First up, the Dead Sea. The Dead Sea is an enclosed basin that borders Jordan and Israel. 4 00:00:17.552 --> 00:00:22.991 Water that flows into the Dead Sea slowly evaporates, leaving salt and mineral deposits behind. 5 00:00:23.390 --> 00:00:27.800 Using instruments like Landsat, we've been able to observe changes in the area of the 6 00:00:27.800 --> 00:00:32.000 Dead Sea through time, but with ICESat-2, we're able to measure changes in the lake 7 00:00:32.000 --> 00:00:34.866 level, or the height of that water surface. 8 00:00:36.268 --> 00:00:41.520 The Skeleton Coast of Namibia is so named because it's a graveyard for ships. 9 00:00:41.520 --> 00:00:44.470 Due to upwelling ocean currents, there's typically 10 00:00:44.470 --> 00:00:49.790 very thick fog in this part of Namibia along with a heavy surf. If you look closely at 11 00:00:49.790 --> 00:00:56.999 the ICESat-2 photon cloud, you can see substantial waves approaching the coast, making it treacherous for ships. 12 00:00:56.999 --> 00:01:02.250 We now turn to Death Valley in southern California. The photons show rugged 13 00:01:02.250 --> 00:01:06.920 terrain surrounding the central basin of Death Valley, which lies several hundred feet below 14 00:01:06.920 --> 00:01:13.359 sea level. Water that flows into Death Valley slowly evaporates over time. In spring, water 15 00:01:13.359 --> 00:01:19.020 can collect into ephemeral lakes that slowly evaporate, much like the Dead Sea. From the 16 00:01:19.020 --> 00:01:23.850 vantage point of space, ICESat-2 continues to measure the height of the Earth and everything 17 00:01:23.850 --> 00:01:27.166 on it, both the living and the dead. 18 00:01:27.166 --> 00:01:30.276 [Music]
