It's the new normal for Arctic sea ice.

00:00:08.130 --> 00:00:12.160
The sea ice pack on the top of the world is nearing its summer minimum.

00:00:12.180 --> 00:00:16.260
And while it probably won’t set a new record this year,

5
00:00:16.280 --> 00:00:20.370
summer ice still covers much less ocean than decades ago.

00:00:28.610 --> 00:00:32.760
The ice is also thinner and younger on average.

00:00:32.780 --> 00:00:36.980

00:00:37.000 --> 00:00:41.060
For the first time this summer, NASA’s Operation IceBridge flew a series of flights over the ice,

12
00:00:41.080 --> 00:00:45.190

00:00:45.210 --> 00:00:49.390

00:00:49.410 --> 00:00:53.570
measuring the thickness of the ice and the depth of melt ponds on the ice surface.

15
00:00:53.590 --> 00:00:57.680
Combining this data with satellite observations will help researchers model the future of Arctic sea ice.
