CHAPTER 11
The Sargasso Sea
THE NAUTILUS didn’t change direction. For the time being, then, we had
to set aside any hope of returning to European seas. Captain Nemo kept
his prow pointing south. Where was he taking us? I was afraid to
guess.
That day the Nautilus crossed an odd part of the Atlantic Ocean. No
one is unaware of the existence of that great warm-water current known
by name as the Gulf Stream. After emerging from channels off Florida,
it heads toward Spitzbergen. But before entering the Gulf of Mexico
near latitude 44 degrees north, this current divides into two arms;
its chief arm makes for the shores of Ireland and Norway while the
second flexes southward at the level of the Azores; then it hits the
coast of Africa, sweeps in a long oval, and returns to the Caribbean
Sea.
Now then, this second arm—more accurately, a collar—forms a ring of
warm water around a section of cool, tranquil, motionless ocean called
the Sargasso Sea. This is an actual lake in the open Atlantic, and the
great current’s waters take at least three years to circle it.
Properly speaking, the Sargasso Sea covers every submerged part of
Atlantis. Certain authors have even held that the many weeds strewn
over this sea were torn loose from the prairies of that ancient
continent. But it’s more likely that these grasses, algae, and fucus
plants were carried off from the beaches of Europe and America, then
taken as far as this zone by the Gulf Stream. This is one of the
reasons why Christopher Columbus assumed the existence of a New
World. When the ships of that bold investigator arrived in the
Sargasso Sea, they had great difficulty navigating in the midst of
these weeds, which, much to their crews’ dismay, slowed them down to a
halt; and they wasted three long weeks crossing this sector.
Such was the region our Nautilus was visiting just then: a genuine
prairie, a tightly woven carpet of algae, gulfweed, and bladder wrack
so dense and compact a craft’s stempost couldn’t tear through it
without difficulty. Accordingly, not wanting to entangle his propeller
in this weed-choked mass, Captain Nemo stayed at a depth some meters
below the surface of the waves.
The name Sargasso comes from the Spanish word “sargazo,” meaning
gulfweed. This gulfweed, the swimming gulfweed or berry carrier, is
the chief substance making up this immense shoal. And here’s why these
water plants collect in this placid Atlantic basin, according to the
expert on the subject, Commander Maury, author of The Physical
Geography of the Sea.
The explanation he gives seems to entail a set of conditions that
everybody knows: “Now,” Maury says, “if bits of cork or chaff, or any
floating substance, be put into a basin, and a circular motion be
given to the water, all the light substances will be found crowding
together near the center of the pool, where there is the least
motion. Just such a basin is the Atlantic Ocean to the Gulf Stream,
and the Sargasso Sea is the center of the whirl.”
I share Maury’s view, and I was able to study the phenomenon in this
exclusive setting where ships rarely go. Above us, huddled among the
brown weeds, there floated objects originating from all over: tree
trunks ripped from the Rocky Mountains or the Andes and sent floating
down the Amazon or the Mississippi, numerous pieces of wreckage,
remnants of keels or undersides, bulwarks staved in and so weighed
down with seashells and barnacles, they couldn’t rise to the surface
of the ocean. And the passing years will someday bear out Maury’s
other view that by collecting in this way over the centuries, these
substances will be turned to stone by the action of the waters and
will then form inexhaustible coalfields. Valuable reserves prepared by
farseeing nature for that time when man will have exhausted his mines
on the continents.
In the midst of this hopelessly tangled fabric of weeds and fucus
plants, I noted some delightful pink-colored, star-shaped alcyon
coral, sea anemone trailing the long tresses of their tentacles, some
green, red, and blue jellyfish, and especially those big rhizostome
jellyfish that Cuvier described, whose bluish parasols are trimmed
with violet festoons.
We spent the whole day of February 22 in the Sargasso Sea, where fish
that dote on marine plants and crustaceans find plenty to eat. The
next day the ocean resumed its usual appearance.
From this moment on, for nineteen days from February 23 to March 12,
the Nautilus stayed in the middle of the Atlantic, hustling us along
at a constant speed of 100 leagues every twenty-four hours. It was
obvious that Captain Nemo wanted to carry out his underwater program,
and I had no doubt that he intended, after doubling Cape Horn, to
return to the Pacific South Seas.
So Ned Land had good reason to worry. In these wide seas empty of
islands, it was no longer feasible to jump ship. Nor did we have any
way to counter Captain Nemo’s whims. We had no choice but to
acquiesce; but if we couldn’t attain our end through force or cunning,
I liked to think we might achieve it through persuasion. Once this
voyage was over, might not Captain Nemo consent to set us free in
return for our promise never to reveal his existence? Our word of
honor, which we sincerely would have kept. However, this delicate
question would have to be negotiated with the captain. But how would
he receive our demands for freedom? At the very outset and in no
uncertain terms, hadn’t he declared that the secret of his life
required that we be permanently imprisoned on board the Nautilus?
Wouldn’t he see my four-month silence as a tacit acceptance of this
situation? Would my returning to this subject arouse suspicions that
could jeopardize our escape plans, if we had promising circumstances
for trying again later on? I weighed all these considerations, turned
them over in my mind, submitted them to Conseil, but he was as baffled
as I was. In short, although I’m not easily discouraged, I realized
that my chances of ever seeing my fellow men again were shrinking by
the day, especially at a time when Captain Nemo was recklessly racing
toward the south Atlantic!
During those nineteen days just mentioned, no unique incidents
distinguished our voyage. I saw little of the captain. He was at
work. In the library I often found books he had left open, especially
books on natural history. He had thumbed through my work on the great
ocean depths, and the margins were covered with his notes, which
sometimes contradicted my theories and formulations. But the captain
remained content with this method of refining my work, and he rarely
discussed it with me. Sometimes I heard melancholy sounds
reverberating from the organ, which he played very expressively, but
only at night in the midst of the most secretive darkness, while the
Nautilus slumbered in the wilderness of the ocean.
During this part of our voyage, we navigated on the surface of the
waves for entire days. The sea was nearly deserted. A few sailing
ships, laden for the East Indies, were heading toward the Cape of Good
Hope. One day we were chased by the longboats of a whaling vessel,
which undoubtedly viewed us as some enormous baleen whale of great
value. But Captain Nemo didn’t want these gallant gentlemen wasting
their time and energy, so he ended the hunt by diving beneath the
waters. This incident seemed to fascinate Ned Land intensely. I’m sure
the Canadian was sorry that these fishermen couldn’t harpoon our
sheet-iron cetacean and mortally wound it.
During this period the fish Conseil and I observed differed little
from those we had already studied in other latitudes. Chief among them
were specimens of that dreadful cartilaginous genus that’s divided
into three subgenera numbering at least thirty-two species: striped
sharks five meters long, the head squat and wider than the body, the
caudal fin curved, the back with seven big, black, parallel lines
running lengthwise; then perlon sharks, ash gray, pierced with seven
gill openings, furnished with a single dorsal fin placed almost
exactly in the middle of the body.
Some big dogfish also passed by, a voracious species of shark if there
ever was one. With some justice, fishermen’s yarns aren’t to be
trusted, but here’s what a few of them relate. Inside the corpse of
one of these animals there were found a buffalo head and a whole calf;
in another, two tuna and a sailor in uniform; in yet another, a
soldier with his saber; in another, finally, a horse with its
rider. In candor, none of these sounds like divinely inspired
truth. But the fact remains that not a single dogfish let itself get
caught in the Nautilus’s nets, so I can’t vouch for their voracity.
Schools of elegant, playful dolphin swam alongside for entire
days. They went in groups of five or six, hunting in packs like wolves
over the countryside; moreover, they’re just as voracious as dogfish,
if I can believe a certain Copenhagen professor who says that from one
dolphin’s stomach, he removed thirteen porpoises and fifteen
seals. True, it was a killer whale, belonging to the biggest known
species, whose length sometimes exceeds twenty-four feet. The family
Delphinia numbers ten genera, and the dolphins I saw were akin to the
genus Delphinorhynchus, remarkable for an extremely narrow muzzle four
times as long as the cranium. Measuring three meters, their bodies
were black on top, underneath a pinkish white strewn with small, very
scattered spots.
From these seas I’ll also mention some unusual specimens of croakers,
fish from the order Acanthopterygia, family Scienidea. Some
authors—more artistic than scientific—claim that these fish are
melodious singers, that their voices in unison put on concerts
unmatched by human choristers. I don’t say nay, but to my regret these
croakers didn’t serenade us as we passed.
Finally, to conclude, Conseil classified a large number of flying
fish. Nothing could have made a more unusual sight than the marvelous
timing with which dolphins hunt these fish. Whatever the range of its
flight, however evasive its trajectory (even up and over the
Nautilus), the hapless flying fish always found a dolphin to welcome
it with open mouth. These were either flying gurnards or kitelike sea
robins, whose lips glowed in the dark, at night scrawling fiery
streaks in the air before plunging into the murky waters like so many
shooting stars.
Our navigating continued under these conditions until March 13. That
day the Nautilus was put to work in some depth-sounding experiments
that fascinated me deeply.
By then we had fared nearly 13,000 leagues from our starting point in
the Pacific high seas. Our position fix placed us in latitude 45
degrees 37′ south and longitude 37 degrees 53′ west. These were the
same waterways where Captain Denham, aboard the Herald, payed out
14,000 meters of sounding line without finding bottom. It was here too
that Lieutenant Parker, aboard the American frigate Congress, was
unable to reach the underwater soil at 15,149 meters.
Captain Nemo decided to take his Nautilus down to the lowest depths in
order to double-check these different soundings. I got ready to record
the results of this experiment. The panels in the lounge opened, and
maneuvers began for reaching those strata so prodigiously far removed.
It was apparently considered out of the question to dive by filling
the ballast tanks. Perhaps they wouldn’t sufficiently increase the
Nautilus’s specific gravity. Moreover, in order to come back up, it
would be necessary to expel the excess water, and our pumps might not
have been strong enough to overcome the outside pressure.
Captain Nemo decided to make for the ocean floor by submerging on an
appropriately gradual diagonal with the help of his side fins, which
were set at a 45 degrees angle to the Nautilus’s waterline. Then the
propeller was brought to its maximum speed, and its four blades
churned the waves with indescribable violence.
Under this powerful thrust the Nautilus’s hull quivered like a
resonating chord, and the ship sank steadily under the
waters. Stationed in the lounge, the captain and I watched the needle
swerving swiftly over the pressure gauge. Soon we had gone below the
livable zone where most fish reside. Some of these animals can thrive
only at the surface of seas or rivers, but a minority can dwell at
fairly great depths. Among the latter I observed a species of dogfish
called the cow shark that’s equipped with six respiratory slits, the
telescope fish with its enormous eyes, the armored gurnard with gray
thoracic fins plus black pectoral fins and a breastplate protected by
pale red slabs of bone, then finally the grenadier, living at a depth
of 1,200 meters, by that point tolerating a pressure of 120
atmospheres.
I asked Captain Nemo if he had observed any fish at more considerable
depths.
“Fish? Rarely!” he answered me. “But given the current state of marine
science, who are we to presume, what do we really know of these
depths?”
“Just this, captain. In going toward the ocean’s lower strata, we know
that vegetable life disappears more quickly than animal life. We know
that moving creatures can still be encountered where water plants no
longer grow. We know that oysters and pilgrim scallops live in 2,000
meters of water, and that Admiral McClintock, England’s hero of the
polar seas, pulled in a live sea star from a depth of 2,500 meters. We
know that the crew of the Royal Navy’s Bulldog fished up a starfish
from 2,620 fathoms, hence from a depth of more than one vertical
league. Would you still say, Captain Nemo, that we really know
nothing?”
“No, professor,” the captain replied, “I wouldn’t be so
discourteous. Yet I’ll ask you to explain how these creatures can live
at such depths?”
“I explain it on two grounds,” I replied. “In the first place, because
vertical currents, which are caused by differences in the water’s
salinity and density, can produce enough motion to sustain the
rudimentary lifestyles of sea lilies and starfish.”
“True,” the captain put in.
“In the second place, because oxygen is the basis of life, and we know
that the amount of oxygen dissolved in salt water increases rather
than decreases with depth, that the pressure in these lower strata
helps to concentrate their oxygen content.”
“Oho! We know that, do we?” Captain Nemo replied in a tone of mild
surprise. “Well, professor, we have good reason to know it because
it’s the truth. I might add, in fact, that the air bladders of fish
contain more nitrogen than oxygen when these animals are caught at the
surface of the water, and conversely, more oxygen than nitrogen when
they’re pulled up from the lower depths. Which bears out your
formulation. But let’s continue our observations.”
My eyes flew back to the pressure gauge. The instrument indicated a
depth of 6,000 meters. Our submergence had been going on for an
hour. The Nautilus slid downward on its slanting fins, still
sinking. These deserted waters were wonderfully clear, with a
transparency impossible to convey. An hour later we were at 13,000
meters—about three and a quarter vertical leagues—and the ocean floor
was nowhere in sight.
However, at 14,000 meters I saw blackish peaks rising in the midst of
the waters. But these summits could have belonged to mountains as high
or even higher than the Himalayas or Mt. Blanc, and the extent of
these depths remained incalculable.
Despite the powerful pressures it was undergoing, the Nautilus sank
still deeper. I could feel its sheet-iron plates trembling down to
their riveted joins; metal bars arched; bulkheads groaned; the lounge
windows seemed to be warping inward under the water’s pressure. And
this whole sturdy mechanism would surely have given way, if, as its
captain had said, it weren’t capable of resisting like a solid block.
While grazing these rocky slopes lost under the waters, I still
spotted some seashells, tube worms, lively annelid worms from the
genus Spirorbis, and certain starfish specimens.
But soon these last representatives of animal life vanished, and three
vertical leagues down, the Nautilus passed below the limits of
underwater existence just as an air balloon rises above the breathable
zones in the sky. We reached a depth of 16,000 meters—four vertical
leagues—and by then the Nautilus’s plating was tolerating a pressure
of 1,600 atmospheres, in other words, 1,600 kilograms per each square
centimeter on its surface!
“What an experience!” I exclaimed. “Traveling these deep regions where
no man has ever ventured before! Look, captain! Look at these
magnificent rocks, these uninhabited caves, these last global haunts
where life is no longer possible! What unheard-of scenery, and why are
we reduced to preserving it only as a memory?”
“Would you like,” Captain Nemo asked me, “to bring back more than just
a memory?”
“What do you mean?”
“I mean that nothing could be easier than taking a photograph of this
underwater region!”
Before I had time to express the surprise this new proposition caused
me, a camera was carried into the lounge at Captain Nemo’s
request. The liquid setting, electrically lit, unfolded with perfect
clarity through the wide-open panels. No shadows, no blurs, thanks to
our artificial light. Not even sunshine could have been better for our
purposes. With the thrust of its propeller curbed by the slant of its
fins, the Nautilus stood still. The camera was aimed at the scenery on
the ocean floor, and in a few seconds we had a perfect negative.
I attach a print of the positive. In it you can view these primordial
rocks that have never seen the light of day, this nether granite that
forms the powerful foundation of our globe, the deep caves cut into
the stony mass, the outlines of incomparable distinctness whose far
edges stand out in black as if from the brush of certain Flemish
painters. In the distance is a mountainous horizon, a wondrously
undulating line that makes up the background of this landscape. The
general effect of these smooth rocks is indescribable: black,
polished, without moss or other blemish, carved into strange shapes,
sitting firmly on a carpet of sand that sparkled beneath our streams
of electric light.
Meanwhile, his photographic operations over, Captain Nemo told me:
“Let’s go back up, professor. We mustn’t push our luck and expose the
Nautilus too long to these pressures.”
“Let’s go back up!” I replied.
“Hold on tight.”
Before I had time to realize why the captain made this recommendation,
I was hurled to the carpet.
Its fins set vertically, its propeller thrown in gear at the captain’s
signal, the Nautilus rose with lightning speed, shooting upward like
an air balloon into the sky. Vibrating resonantly, it knifed through
the watery mass. Not a single detail was visible. In four minutes it
had cleared the four vertical leagues separating it from the surface
of the ocean, and after emerging like a flying fish, it fell back into
the sea, making the waves leap to prodigious heights.
