00:00:00,060 --> 00:00:04,110
Music: Drumbeats. Narrator: This year, NASA is launching

2
00:00:04,130 --> 00:00:08,170
eight major field campaigns to study our changing planet from the air,

3
00:00:08,190 --> 00:00:12,250
sea, and on the ground. Here’s a quick guide to all eight missions.

4
00:00:12,270 --> 00:00:16,450
First up, Oceans Melting Greenland,

5
00:00:16,470 --> 00:00:20,540
or OMG, heads to north to measure the effects of warm ocean

6
00:00:20,560 --> 00:00:24,710
water on Greenland’s tidewater glaciers.

7
00:00:24,730 --> 00:00:28,830
Just a bit further south,

8
00:00:28,850 --> 00:00:32,950
NAAMES will study the relationships between marine ecosystems,

9
00:00:32,970 --> 00:00:37,140
including plankton, and the atmosphere.

10
00:00:41,270 --> 00:00:45,350
ACT-America will fly over the central United States,

11
00:00:45,370 --> 00:00:49,430
trying to pinpoint both sources and sinks of greenhouse gases

12
00:00:49,450 --> 00:00:53,510
like carbon and methane.

13
00:00:53,530 --> 00:00:57,610
ABoVE is a combination of 39 different projects

14
00:00:57,630 --> 00:01:01,720
studying the changing Arctic in Alaska and Canada,

15
00:01:01,740 --> 00:01:05,900
from wildfires to wildlife to permafrost.

16
00:01:05,920 --> 00:01:09,960
The ATom mission

17
00:01:09,980 --> 00:01:14,060
will cover a lot of sky, from the Arctic to the Antarctic

18
00:01:14,080 --> 00:01:18,150
and back again, studying how human-produced air pollution affects

19
00:01:18,170 --> 00:01:22,340
affects greenhouse gases.

20
00:01:22,360 --> 00:01:26,450
The CORAL mission will cover vast

21
00:01:26,470 --> 00:01:30,570
stretches of Pacific coral reefs, studying the health

22
00:01:30,590 --> 00:01:34,730
of these vital ecosystems.

23
00:01:34,750 --> 00:01:38,790
Building on

24
00:01:38,810 --> 00:01:42,870
similar air quality missions in the United States, KORUS-AQ

25
00:01:42,890 --> 00:01:46,960
is an international effort to study the air quality over South Korea.

26
00:01:51,080 --> 00:01:55,290
Finally,
