1
Far From Home, Chronicles of an Open Ocean Voyage, by Sophie Webb My name is Sophie.
2
I work as a field biologist and naturalist specializing in birds.
3
Tomorrow I am going on a four -month journey to the Eastern Tropical Pacific Ocean, ETP, to study seabirds and marine mammals.
4
I work for the Southwest Fisheries Science Center,
5
a research laboratory run by the National Oceanic and Atmospheric Administration, NOAA, in California.
6
The cruise's main goal is to discover what has happened to dolphins' populations that have been affected by the tuna -persane fishery.
7
However, we will also observe and count all other marine mammals that we encounter, count the seabirds, my main job,
8
make oceanographic measurements, and study flying fish and squid.
9
As scientists, we want to understand the ecosystem as a whole, not only one part.
10
The ETP, where we will work, is a huge portion of the Pacific, the world's largest ocean.
11
It extends south from California to Peru and west to Hawaii and on an area of 7 .7 million square miles,
12
larger than the continent of Africa.
13
The open ocean, far from land, can seem lonely and empty, yet there are areas in the ETP that are full of amazing wildlife.
14
Because it is so difficult to study these deep -sea animals far from shore, little is known about their natural history and ecology.
15
My shipmates and I are about to embark on an incredible opportunity to explore this complex and exciting ecosystem.
16
July, San Diego, California.
17
I drive south from my home in Central California to San Diego.
18
There I spend several days helping load scientific equipment aboard the NOAA ship MacArthur II and setting up our work areas.
19
Over the flying bridge, the highest deck on the ship, the ship's crew has strung a canvas canopy to provide shade.
20
We will be grateful for the shade as we head south into the sunny tropics.
21
We've installed four sets of big eyes, which will be key to our observations.
22
We use these enormous mounted binoculars with a 25 power magnification to scan to the horizon for marine animals
23
or count distant bird flocks.
24
Three computer stations with chairs are also set up.
25
Two stations, one per side, are where we birders sit to collect our bird data.
26
The third one, in the middle, is where the marine mammal data recorder sits.
27
A bird's eye view of the flying bridge shows the location of our stations in the big eyes.
28
There are 37 people on the ship.
29
15 are scientists, one chief scientist, six marine mammal observers, two birders, one of them is me,
30
two oceanographers, and four visiting scientists.
31
The remaining 22 aboard include the captain, cooks, engineers, a variety of NOAA officers who navigate and drive the ship,
32
and the deck department folks who clean and paint the ship
33
and help us collect our data by driving the small boats
34
and running the cranes and winches for casting nets and other equipment.
35
I have worked with many of the scientists before and know most of the ship's crew well.
36
I've spent almost two of the past four years living and working on the MacArthur II, so the first few days are always fun,
37
catching up with others and learning what they have been doing over the months since the last trip.
38
Although over the next months we will collect data on many aspects of the marine ecosystems,
39
the primary focus of the trip is to find out what is happening to the population of spotted and spinner dolphins.
40
The dry lab where the computers are located
41
There is a wet lab as well, with two large sinks
42
One with fresh water, the other with salt water
43
Where the samples from net toes and other scientific activities are processed
44
Why do we want to know about spotted and spinner dolphin numbers?
45
There are several threats to these animals
46
The primary one used to be the yellowfin tuna fishery
47
In the ETP, tuna and dolphins are often found in large schools together.
48
Tuna frequently are caught by a method called purse scening.
49
A net is dragged to surround a tuna school, then drawn closed.
50
If there are dolphins with the tuna, they are caught as well.
51
In the past, tens of thousands of dolphins drowned each year in purse scenes.
52
This needless loss of life caused a great outcry by the general public and scientists in the 1970s.
53
Thank you.
54
The result was the formation of the United States Marine Mammals Protection Act, which protects dolphins and other marine mammals in U .S waters.
55
Now most marine mammals are also protected by international law.
56
A graph showing how the numbers of dolphins killed in the yellowfin tuna purse scene fishery has declined.
57
Currently, scientists closely monitor the tuna fishery.
58
Now most tuna fishermen allow the dolphins to escape before they drown, sometimes with a swimmer in the net to help the dolphins escape.
59
But dolphin populations are not recovering as quickly as predicted, and scientists don't know why.
60
Does capture cause stress that lowers their survival?
61
Or perhaps overfishing and pollution combined with shifts in climate may be affecting the balance of the ecosystem?
62
With long -term monitoring combined with ecosystem studies, we hope to understand why these populations aren't recovering at a faster rate.
63
A tuna purse senor hauls in its net.
64
The yellow skiffs round up the tuna and dolphins into the net.
65
As the net is drawn closed, the tuna dive down and the dolphins swim out.
66
A helicopter and a manned crow's nest, a lookout platform at the top of a tall mast, are used to spot distant tuna schools.
67
Bird flocks are often a clue that the fishermen look for.
68
Finally, we are ready to leave San Diego.
69
Before each long journey, there is always a sense of anticipation.
70
What will we see this time?
71
There is, however, a downside to every long trip.
72
I know I will miss my home, family, and friends.
73
Heading south Over the next days, we move offshore and head south to warm tropical water.
74
Our route takes us south of the Hawaiian Islands.
75
In a few weeks, after a month at sea, we will turn and head north to Hawaii to resupply and fuel the ship.
76
The ocean color has changed since we left San Diego.
77
It is a beautiful clear blue.
78
I look down through the water and it seems as though I can see for miles.
79
Here the water can be much more than a mile deep.
80
It looks nothing like the ocean near shore off California,
81
which has a murky green or brownish cast to it caused by lots of plankton and algae.
82
The tropical ocean is clear because it has much less of these.
83
This net, called a bongo because it looks like the drum, is used for catching small fish and plankton.
84
Some creatures frequently caught in a bongo tow are pictured here, clockwise.
85
A spotted larvae squid, a semi -clear larval octopus, and a krill.
86
Krill are small relatives of shrimp and are an important food for whales and birds.
87
Where there is food, there are animals.
88
In the tropical ocean, animals tend to be found in patches where there is more plankton and algae.
89
Small fish and krill eat the plankton and algae.
90
Larger fish and squid eat them, and so on up the food chain to tuna and dolphins.
91
One of the things we want to understand is what causes this patchiness.
92
We combine our marine mammal and seabird observations with measurements of water, plankton, and algae.
93
Every morning an hour before sunrise and every evening an hour after sunset,
94
we collect water samples from the surface down to 1 ,000 meters to look at the water's nutrients and chlorophyll.
95
These nutrients are the building blocks of the ocean food chain.
96
In the evening, we also deploy nets to determine the amount and types of plankton at different depths.
97
We use dip nets to catch flying fish and squid.
98
All this information helps us have a more complete picture of the ecosystem of the tropical ocean.
99
A graph of water sampling shows measurements of oxygen,
100
temperature, and salinity, salt, in the water from the surface to 1 ,000 meters, 3 ,000 feet.
101
As one follows the graph from 1 ,000 meters to the surface, note the drastic changes of depth of about 100 meters.
102
Oxygen and temperature increases sharply as the salinity decreases.
103
This is where two different water masses meet and is called the thermocline.
104
A thermocline that is strong and close to the surface, 50 to 100 meters,
105
can indicate a highly productive area where we might find not only a large amount of algae and plankton,
106
but also animals much higher in the food chain, such as tuna and dolphin.
107
A Day Offshore The day dawns clear and calm, absolutely beautiful.
108
The seas are glassy, Beaufort O, a nautical scale that assigns numbers based on wind speed and waves.
109
Observations start just after dawn, when there is enough light to see out to the horizon.
110
Everyone is ready on the flying bridge.
111
Cornelia, a German marine mammal biologist, and Ernesto, a Mexican marine mammal biologist,
112
stand on each side of the flying bridge to scan with the big eyes for marine mammals.
113
Jim, an American marine mammal biologist, sits in the middle at data computer.
114
I sit with handheld binoculars on either the port left or the starboard right side,
115
depending on where I can avoid the sun's glare to scan for birds.
116
At Beaufort Zero, the ocean is glassy calm.
117
One can see for miles.
118
The pink and violet sunrise reflects on the still water.
119
It's time to start looking for critters.
120
It is ten minutes past sunrise, and the light is good.
121
We start to travel along a set course, what scientists call a transect.
122
Soon after we start, Cornelia yells, DOLPHINS!
123
Ball scanning stops and everyone focuses on Cornelia's sighting.
124
Cornelia scans out to the horizon, looking through the big eyes.
125
What Cornelia sees through the big eyes.
126
She swings the big eyes in the direction of the dolphins.
127
Using her handheld radio, Cornelia calls the captain on the bridge deck below us, where the ship's steering controls are located.
128
Bridge!
129
Flying bridge!
130
We have dolphins, she says.
131
Please turn 20 degrees to the left.
132
Over.
133
The ship turns.
134
At first, all we see are several dorsal fins around the log.
135
We approach the dolphins slowly.
136
One brown booby and four Nazca boobies rest on a log surrounded by dolphins.
137
Boobies are often seen far out at sea, resting on any available floating object, including ships and sea turtles.
138
Finally, we see odd sloped foreheads and long beaks.
139
They are rough -toothed dolphins.
140
This species is found in many oceans.
141
Although relatively common, little is known of their natural history due to their deep ocean habitat.
142
All creatures that inhabit the deep oceans are difficult to study.
143
What I imagine it looks like below the log, Frequently, rough -toothed dolphins investigate logs,
144
feeding on the fish that hide in the seaweed growing on the log.
145
Many different animals are attracted to the habitat the log creates.
146
Rough -toothed dolphins specialize in eating large fish such as the mahi -mahi.
147
The water is so clear, I see subtle markings on the dolphins as they swim by.
148
All dolphins are odontocetes, toothed whales.
149
Odontocetes also include porpoises, the little -known beaked whales, killer whales, and sperm whales.
150
There is a great variation in size from the tiny harbor purpose
151
that measures 1 .2 meters to the 18 .5 meter male sperm whale.
152
We complete the rough -toothed dolphin count.
153
There are 12 in the group and no calves, babies.
154
Marine mammal biologists always note the presence or absence of calves
155
and immature animals to gain clues about when and where the dolphins reproduce.
156
We leave the dolphins by their log and continue on our course.
157
The day becomes progressively warmer.
158
The air is still.
159
Everyone is sleepy.
160
The ship drones on along the transit line.
161
We see no more marine mammals now, but birds occasionally fly by, such as the Sparrow -sized Palapagos storm patrol.
162
I record birds up to 300 meters, 630 feet, on one side of the ship.
163
Even when there are few birds, I have to stay focused and alert.
164
I don't want to miss any of them in my count.
165
Galapagos storm patrols are found far out at sea feeding on small crustaceans, halibuts, the only marine insect,
166
fish, and jellyfish at the ocean's surface.
167
They breed on the remote and protected Galapagos Islands, which have few predators.
168
Their populations at the moment appear to be stable.

- استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
- ردّد جملة جملة بالسرعة العادية، وكرّر كل جملة حتى يتطابق إيقاعك مع المتحدث.
- سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل dolphin, tuna, meter.
ما هي تقنية التظليل الصوتي؟
التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
