[ocean sounds] [music throughout]

2
00:00:04.060 --> 00:00:08.240
Narrator: Cape Cod, MA is known for its beautiful beaches.

3
00:00:08.260 --> 00:00:12.390
This scenic landscape is also home

4
00:00:12.410 --> 00:00:16.410
to one of the most frequent marine mammal stranding sites in the world.

00:00:16.430 --> 00:00:20.510
[dolphin breathing]

6
00:00:20.530 --> 00:00:24.600
[dolphin breathing] Narrator: Scientist know very little about what causes

7
00:00:24.620 --> 00:00:28.730
these animals to strand.

8
00:00:28.750 --> 00:00:32.940
What has been proven is that a quick and efficient response in these moments

9
00:00:32.960 --> 00:00:37.000
is a matter of life and death.

10
00:00:37.020 --> 00:00:41.150
Katie Moore: If we can get there quickly and provide supportive care they have a much better prognosis

11
00:00:41.170 --> 00:00:45.290
in terms of survival.

12
00:00:45.310 --> 00:00:49.400
Narrator: Katie Moore works on the front lines, as the Deputy Vice President of Conservation and Animal Welfare at the International Fund for Animal Welfare.

13
00:00:49.420 --> 00:00:53.450
Through Moore’s fine-tuned rescue efforts, she has increased the survival rate

14
00:00:53.470 --> 00:00:57.560
from 14% to 75%, but the question remains:

15
00:00:57.580 --> 00:01:01.680
Could it be possible to predict, rather than

16
00:01:01.700 --> 00:01:05.780
react to, these events?

17
00:01:05.800 --> 00:01:09.920
Katie Moore: If we develop an algorithm that pieces together the different variables

18
00:01:09.940 --> 00:01:13.990
that may be causing mass strandings or driving driving them,

19
00:01:14.010 --> 00:01:18.090
we'd have the ability to then prevent them.

20
00:01:18.110 --> 00:01:22.250
We can have teams out on the shore, looking for animals in those hotspots, knowing that all those variables

21
00:01:22.270 --> 00:01:26.310
have come together, and this is the likely point in time where we are likely to see it.

22
00:01:26.330 --> 00:01:30.380
We can also have teams ready to respond, so that if they do strand, we are there that much faster,

23
00:01:30.400 --> 00:01:34.490
and more animals will survive the event.

24
00:01:34.510 --> 00:01:38.700
Narrator: In Cape Cod, the annual number of stranded animals ranges from less than 10 to over 200.

25
00:01:38.720 --> 00:01:42.880
Some of the most affected species include

26
00:01:42.900 --> 00:01:46.930
pilot whales and whitesided dolphins,

27
00:01:46.950 --> 00:01:51.050
creatures that are typically found in deeper water, rather than along the coast.

28
00:01:51.070 --> 00:01:55.110
The ongoing search for answers began 400 miles

29
00:01:55.130 --> 00:01:59.220
away at the Bureau of Ocean Energy Management in Sterling, VA.

30
00:01:59.240 --> 00:02:03.410
There, fellow marine biologist Desray Reeb had some initial thoughts on

31
00:02:03.430 --> 00:02:07.550
triggers for these events.

32
00:02:07.570 --> 00:02:11.630
Desray Reeb: For the large proportion of these strandings the animal

33
00:02:11.650 --> 00:02:15.730
are across the ages, in pretty good health, and there's no really

34
00:02:15.750 --> 00:02:19.900
immediate evidence as to why they actually strand.

35
00:02:19.920 --> 00:02:24.060
[water sound] Narrator: Geomagnetic perception,

36
00:02:24.080 --> 00:02:28.240
the ability to navigate using Earth’s magnetic field,

37
00:02:28.260 --> 00:02:32.330
is a feature thought to exist in marine mammals.

38
00:02:32.350 --> 00:02:36.430
Could changes in the magnetic field confuse the animals?

39
00:02:36.450 --> 00:02:40.460
sensors like magnetometers can detect changes

40
00:02:40.480 --> 00:02:44.960
- called geomagnetic pulses or storms -

41
00:02:44.980 --> 00:02:36.760
One cause of such changes is activity from the sun known as space weather.

42
00:02:36.780 --> 00:02:48.890
Sensors like magnetometers can detect changes

43
00:02:48.910 --> 00:02:53.000
Desray Reeb: Geomagnetic perception is one of the theories.

44
00:02:53.020 --> 00:02:57.180
I thought, well, hmmm...if a magnetometer

45
00:02:57.200 --> 00:03:01.270
can pick it up, maybe the animals actually can pick it up.

46
00:03:01.290 --> 00:03:05.370
Dr. Reeb brought her hypothesis to Antti Pulkkinen, Research Astrophysicist

47
00:03:05.390 --> 00:03:09.410
from the Heliophysics department at NASA’s Goddard Space Flight Center in Greenbelt, MD.

48
00:03:09.430 --> 00:03:13.560
Antti Pulkkinen: The coolest thing was we realized

49
00:03:13.580 --> 00:03:17.660
that nobody had really taken a cold, hard data science analysis look at this problem

50
00:03:17.680 --> 00:03:21.760
Narrator: By combining Katie’s records

51
00:03:21.780 --> 00:03:25.880
on marine mammal strandings in Cape Cod and Antti’s records of the changes in Earth’s magnetic field,

52
00:03:25.900 --> 00:03:29.970
the team of researchers had a starting point.

53
00:03:29.990 --> 00:03:34.080
Katie Moore: What we are trying to look at here was if there was a potential driver or

54
00:03:34.100 --> 00:03:38.230
relationship or correlation between the occurrence of mass strandings

55
00:03:38.250 --> 00:03:42.320
and any solar activity.

56
00:03:42.340 --> 00:03:46.400
Antti Pulkkinen: So, the data we have correlated or analyzed so far is information about local geomagnetic conditions.

57
00:03:46.420 --> 00:03:50.570
We have long data records from geophysical observatories

58
00:03:50.590 --> 00:03:54.610
of the local geomagnetic field variations

59
00:03:54.630 --> 00:03:58.800
and marine mammal strandings.

60
00:03:58.820 --> 00:04:02.980
Narrator: When the team analyzed all the data, they found that measurements from the the same time period or random time periods

61
00:04:03.000 --> 00:04:07.080
produced similar results, meaning that there is no obvious

62
00:04:07.100 --> 00:04:11.260
relationship between geomagnetic changes and stranding in Cape Cod.

63
00:04:11.280 --> 00:04:15.420
If space weather wasn’t the trigger, what could be?

64
00:04:15.440 --> 00:04:19.540
Desray Reeb: The easy fix correlation between the geomagnetic pulse

65
00:04:19.560 --> 00:04:23.710
and “Ohh! A stranding!” doesn't seem to be very

66
00:04:23.730 --> 00:04:27.780
evident, but what it does show is that there are multiple variables

67
00:04:27.800 --> 00:04:31.890
involved in this equation. The geomagnetic storms could

68
00:04:31.910 --> 00:04:35.990
be one very small part of it - significant still - but

69
00:04:36.010 --> 00:04:40.210
it looks like there are multiple oceanographic and environmental elements

70
00:04:40.230 --> 00:04:44.290
Narrator: The scientists considered what other variables

71
00:04:44.310 --> 00:04:48.340
may exist in the air or water that could change animal behavior.

72
00:04:48.360 --> 00:04:52.470
Tides or winds could be disruptive.

73
00:04:52.490 --> 00:04:56.530
Ocean color - measurements of the water’s chemical and particle content -

74
00:04:56.550 --> 00:05:00.580
Perhaps sea surface temperature

75
00:05:00.600 --> 00:05:04.710
was a factor too.

76
00:05:04.730 --> 00:05:08.740
With the help of data from NASA Earth Science missions, they could also explore these possibilities.

77
00:05:08.760 --> 00:05:12.860
[Antti talks to team]

78
00:05:12.880 --> 00:05:17.000
Narrator: With more data in hand, it was time to expand the team.

79
00:05:17.020 --> 00:05:21.100
They recruited statisticians, and the expertise of NASA Earth Science

80
00:05:21.120 --> 00:05:25.220
data analyst and oceanographer Erdem Karaköylü.

81
00:05:25.240 --> 00:05:29.290
Erdem Karaköylü: A data set, no matter its shape or content, it always

82
00:05:29.310 --> 00:05:33.380
has a story to tell.

83
00:05:33.400 --> 00:05:37.500
Trying to figure out how the different data are connected requires a wide diversity of stills and background knowledge.

84
00:05:37.520 --> 00:05:41.670
Katie Moore: For example, I'll be explaining

85
00:05:41.690 --> 00:05:45.740
how a mass stranding how we respond to try and understand why

86
00:05:45.760 --> 00:05:49.850
we are presenting the data in a certain way, and my colleagues from NASA will look at me and ask

87
00:05:49.870 --> 00:05:53.970
questions that I wouldn't think to ask, because I take for granted my understanding, and they are coming

88
00:05:53.990 --> 00:05:58.150
at it from a totally new angle with no background.

89
00:05:58.170 --> 00:06:02.260
Narrator: The group hopes to combine these data sets in a way that reveals a pattern, allowing them to predict the likelihood

90
00:06:02.280 --> 00:06:06.320
and location of mass strandings before they happen.

91
00:06:06.340 --> 00:06:10.380
Desray Reeb: We've really just slowly peeled the first layer of this onion back.

92
00:06:10.400 --> 00:06:14.520
I think there is so many more layers

93
00:06:14.540 --> 00:06:18.680
that still need to be addressed and looked at.

94
00:06:18.700 --> 00:06:22.780
I hope that we can actually find additional collaborators and funding partners to really bring all the data

95
00:06:22.800 --> 00:06:26.850
that is really available to really give this the study

96
00:06:26.870 --> 00:06:30.980
and the scrutiny that it deserves.

97
00:06:31.000 --> 00:06:35.160
Antti Pulkkinen: And we are also going to make all these data sets available to the entire scientific community,

98
00:06:35.180 --> 00:06:39.270
so that we can utilize the entire scientific community to attack and approach this problem.

99
00:06:39.290 --> 00:06:43.440
and approach this problem.

100
00:06:43.460 --> 00:06:47.550
Narrator: The project’s legacy rests not only in a predictive tool, but also as an example

101
00:06:47.570 --> 00:06:51.690
for collaborative research moving forward.

102
00:06:51.710 --> 00:06:55.770
Erdem Karaköylü: I think that there will be other things that that people might be able to take and run with

103
00:06:55.790 --> 00:06:59.770
maybe add more data. I'm hoping also that it will be a model

104
00:06:59.790 --> 00:07:03.820
for how projects can then be open to the wider public.

[rescue volunteers talking]

106
00:07:08.000 --> 00:07:12.170
Narrator: With the potential for an even broader collaboration ahead,

107
00:07:12.190 --> 00:07:16.380
Katie's rescue team is optimistic that they will gain a deeper

108
00:07:16.400 --> 00:07:20.460
understanding of strandings - and ultimately - save more lives.

109
00:07:20.480 --> 00:07:24.640
Katie Moore: The ability to release animals after they have stranded is tremendous.

110
00:07:24.660 --> 00:07:28.720
When we do that, that's the best feeling in the world after all that hard work.

111
00:07:28.740 --> 00:07:32.820
Desray: those questions that seem unanswerable,

112
00:07:32.840 --> 00:07:37.010
if you give them time, and support,

113
00:07:37.030 --> 00:07:41.090
and effort, and put people on them, we can do amazing things.
