Silence

00:00:09.130 --> 00:00:12.170
Earth is the water

5
00:00:12.190 --> 00:00:15.200
planet. Although forty percent
of

6
00:00:15.220 --> 00:00:18.220
Earth's population lives within
or near

7
00:00:18.240 --> 00:00:21.240
coastal regions, the ocean
impacts

8
00:00:21.260 --> 00:00:24.260
people everywhere.

00:00:24.280 --> 00:00:27.290
Music

10
00:00:27.310 --> 00:00:30.310
Most of Earth's water is stored
in the ocean -

11
00:00:30.330 --> 00:00:33.340
a driving force for weather

12
00:00:33.360 --> 00:00:36.370
and climate.

Music

15
00:00:42.460 --> 00:00:45.890
The Earth's surface is warmed
unevenly by the sun.

16
00:00:45.910 --> 00:00:48.980
Heat, a form of energy, helps

17
00:00:49.000 --> 00:00:52.010
drive ocean and atmospheric
circulation.

18
00:00:52.030 --> 00:00:55.050
Music

19
00:00:55.070 --> 00:00:58.180
The ocean absorbs and stores
more heat than the atmosphere.

20
00:00:58.200 --> 00:01:01.380
Both the atmosphere and ocean
move heat;

21
00:01:01.400 --> 00:01:04.560
the atmosphere does this
quickly, the ocean

22
00:01:04.580 --> 00:01:07.560
slowly.

23
00:01:07.580 --> 00:01:10.750
Music

24
00:01:10.770 --> 00:01:13.940
At the ocean's surface, winds
drive currents.

00:01:17.150 --> 00:01:20.310

27
00:01:20.330 --> 00:01:23.500
Multiple forces

28
00:01:23.520 --> 00:01:26.550
keep the global ocean conveyor
belt or

29
00:01:26.570 --> 00:01:29.730
Thermohaline Circulation in
perpetual motion.

30
00:01:29.750 --> 00:01:32.910
Below the surface,

31
00:01:32.930 --> 00:01:36.090
deeper currents are driven by
differences in density.

32
00:01:36.110 --> 00:01:39.110
Music

00:01:39.130 --> 00:01:42.170

Music

36
00:01:48.260 --> 00:01:51.280
Mixing and upwelling in

37
00:01:51.300 --> 00:01:54.340
the ocean, transport nutrient
rich waters

38
00:01:54.360 --> 00:01:57.400
to the ocean's surface.
Nutrients

39
00:01:57.420 --> 00:02:00.450
sustain biological productivity
in the ocean.

40
00:02:00.470 --> 00:02:03.500
Extreme variations in

41
00:02:03.520 --> 00:02:06.550
sea surface height and sea
surface temperature

42
00:02:06.570 --> 00:02:09.620
affect ocean and atmospheric
circulation.

43
00:02:09.640 --> 00:02:12.720
Music

44
00:02:12.740 --> 00:02:15.720
Music

45
00:02:15.740 --> 00:02:18.910
El Nino and La Nina

46
00:02:18.930 --> 00:02:21.960
occur when changing wind
patterns displace

47
00:02:21.980 --> 00:02:25.050
warm and cool water in the
equatorial Pacific.

48
00:02:25.070 --> 00:02:28.150
Both have global

49
00:02:28.170 --> 00:02:31.260
impacts.

00:02:31.280 --> 00:02:34.400
Music

51
00:02:34.420 --> 00:02:37.560
During either of these events
the replacement of cold water

52
00:02:37.580 --> 00:02:40.740
by warm water leads to air
temperature swings and

53
00:02:40.760 --> 00:02:43.740
changes in humidity.

54
00:02:43.760 --> 00:02:46.910
Music

55
00:02:46.930 --> 00:02:50.100
This alters weather patterns by
steering storms

56
00:02:50.120 --> 00:02:53.290
and rainfall to new locations.

57
00:02:53.310 --> 00:02:56.460

Music

59
00:02:59.660 --> 00:03:02.830
Shifts in rainfall affect plant
growth

60
00:03:02.850 --> 00:03:06.010
and areas impacted by drought.

61
00:03:06.030 --> 00:03:09.180

Music

65
00:03:18.330 --> 00:03:21.340
When heat is exchanged between
the ocean's surface

66
00:03:21.360 --> 00:03:24.400
to the atmosphere, it
influences climate.

67
00:03:24.420 --> 00:03:27.450
For example, heat and moisture

68
00:03:27.470 --> 00:03:30.580
carried by the Gulf Stream
northward bring

69
00:03:30.600 --> 00:03:33.750
warmer temperatures and a
moderate climate to Europe.

70
00:03:33.770 --> 00:03:36.890
An eddy is a circular

71
00:03:36.910 --> 00:03:40.070
moving body of water that spins
off a main current.

72
00:03:40.090 --> 00:03:43.260
Eddies play a major role
transporting

73
00:03:43.280 --> 00:03:46.370
heat and nutrients.

74
00:03:46.390 --> 00:03:49.550
Music

75
00:03:49.570 --> 00:03:52.700
Thunderstorms are a frequent
occurrence

76
00:03:52.720 --> 00:03:55.880
in the tropics. Some of these
may become

77
00:03:55.900 --> 00:03:59.070
organized into large rotating
systems with strong

78
00:03:59.090 --> 00:04:02.240
winds, growing into tropical
storms or hurricanes.

Music

80
00:04:05.450 --> 00:04:08.450
Tropical ocean basins like the

81
00:04:08.470 --> 00:04:11.640
Caribbean and the Gulf of
Mexico retain

82
00:04:11.660 --> 00:04:14.820
substantial heat making these
regions favorable for

83
00:04:14.840 --> 00:04:18.000
rapid storm intensification.

84
00:04:18.020 --> 00:04:21.180
Music

85
00:04:21.200 --> 00:04:24.380
By extracting large amounts of
heat

86
00:04:24.400 --> 00:04:27.420
from the ocean, storms can
become

87
00:04:27.440 --> 00:04:30.480
massive and destructive
hurricanes.

A driving force

97
00:04:58.420 --> 00:05:01.540
for weather and climate,

98
00:05:01.560 --> 00:05:04.720
the ocean is essential to life
on Earth.

99
00:05:04.740 --> 00:05:07.900
It is the primary storehouse of
Earth's water.

Music

102
00:05:14.310 --> 00:05:17.470
Without the ocean our planet
would be

00:05:17.490 --> 00:05:20.480
uninhabitable.

view from space are helping to
unveil the

vast and largely unexplored

108
00:05:33.150 --> 00:05:36.310
ocean.
