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.

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.
