“The scale of the place is hard to grasp. You see a mountain or an island that seems a few hours’ walk away and decide to wander over and explore; five days later you’re still walking. The early explorers did this a lot. The problem is not just the size of the features—glaciers that make Alaska look small, mountains that dwarf the Alps—but also the absence of anything against which to judge them. There are no trees, or indeed plants of any kind; no land animals; nothing but glaciers, snowfields and sepia-toned rocks.”
“It can take being in pure emptiness to remind you to let go of your hubris; and it can take being blocked by the power of nature to remind you how precarious our existence is and how tenuous and temporary our mastery. Some find this frightening, but I take a strange kind of comfort from knowing that this patient and implacable continent doesn’t care what we think or do. It will yield warnings if we seek them. We can avert human catastrophe if we act on them. But Antarctica itself is under no threat. That, in the end, is what I love most about it. Antarctica is bigger than all of us, bigger than our technologies, our human strengths and weaknesses, our eagerness to build and our capacity to destroy. Enough ice could slide into the sea to turn West Antarctica into an island archipelago, and to raise the sea to heights that would swamp coastal cities, without causing so much as a flutter in the continent’s cool white heart.”
This author is not the most exciting or lyrical writer, I kept wondering who she was to gain such access to Antarctica, and it turns out she is a respected climate scientist. I prefer Barry Lopez on Antartica, but the deep access the author had to the continent is pretty stunning, even if the prose is a little dry. A lot is well known, but there were sweet gems of wonder that the author slipped in that might lend themselves to a found poem. I was stunned to think that as written above, Antarctica would be fairly immune to sea level rise, but the human stations would be affected, or maybe they are more mobile than say, NYC, so it would be a blip. But the continent down there, rotating in a way so differently than ours, would endure.
I only know one person who has ever been to Antarctica, and I know she was on a cruise but not much else, not sure if she set foot on it, or what she saw, unfortunately. I would like to see the Dry Valleys. The lack of pictures when we are talking about such an extraterrestrial type landscape was jarring; I went down a wormhole of some pictures especially of the Dry Valleys and the mountains and ice sheets. It is truly a otherworldly landscape, and this book was a good overview.
In spite of its size, Antarctica officially belongs to nobody. An international treaty, signed now by the forty-nine countries with a declared interest, forbids commercial exploitation and dedicates the entire place to ‘peace and science’.
Even its apparent barrenness is a large part of its power. People are drawn to Antarctica precisely because so much has been stripped away. The support staff I met there told me that they had come not to find themselves so much as to lose the outside world. The continent lacks most of the normal ways that we interact in human societies.
And with this simplicity of life comes a clarity that’s intoxicating.
The underlying theme of the book is the classic ‘hero’ story, in which the narrator travels to the end of the Earth, to the strangest, most distant lands, only to find a mirror, the girl next door, the key to life back home. But there is also a deeper message, for which Antarctica is the living metaphor. The most experienced Antarcticans talk not about conquering the continent but about surrendering to it. No matter how powerful you believe yourself to be—how good your technology, how rich your invention—Antarctica is always bigger. And if we humans look honestly into this ice mirror, and see how small we are, we may learn a humility that is the first step towards wisdom.
The water is so clear that you can see for 250, maybe 300 yards in the green half-light. Your head tells you that this is impossible, that distant divers cannot be so far away and still so clearly visible, that they must instead be much closer, hanging nearby in the water like tiny Tinker Bells. Nobody is tethered. You float freely to maximise your flexibility, always deeply mindful of the shaft of light, what Sam calls the Jesus beam’, that shoots down from the dive hole and shows the way home.
And below you, the grey sea floor is carpeted with alien creatures. Run your flashlight over them and their colours leap out. There are brittle stars, golden discs that raise themselves up on their five long legs as you approach, and then march away on tiptoe like the Martians from The War of the Worlds; feather stars, 40 cm across, that look like a bundle of bottle brushes and swim by waving their protuberances wildly as if they were drunken octopuses; and sun stars, a sort of bright orange starfish with up to forty arms, which in the waters of McMurdo Sound can grow to a metre or more.
The sea spiders here are more than a thousand times bigger than the ones elsewhere in the world. They stride over the seabed like colossi, a full foot from tip to toe. They are supposed to have eight legs, like their relatives on the land. But some have ten or even twelve.
Why should these creatures be so much bigger than anywhere else? Although it seems paradoxical, the answer lies in the extreme cold temperatures. Life here is necessarily very slow. Chemical reactions take place at an absurdly sluggish rate, and animals can live very much longer than their warmer cousins. On top of that, colder water can dissolve more oxygen, which is essential for growing big.
The McMurdo Dry Valleys are the closest thing we have on Earth to the planet Mars. A set of bare rocky valleys running in parallel from the edge of the ice sheet down to the sea, they are ‘dry’ not just through lack of water, but through lack of ice. They are also all but monochrome. The jagged mountain ranges that separate the valleys are run through like a layer cake with alternate slabs of chocolate brown dolorite and pale sandstone. This is an unearthly place, intimidating and harsh in the bright light of noon. But at night in the summer, when the sun never sets but merely hovers close to the horizon and casts its long low shadows, the peaks seem to soften, the dolorite rock grows richer and the oatmeal sandstone takes on a golden glow. It’s not just the colours that look their best at night-time. Those long shadows also pick out the features that tell the history of this extraordinary place. There are weird raised beaches, jutting out halfway up the mountain sides, which mark ancient high stands of water; rock ripples and gigantic potholes that were once carved out by a waterfall the size of Niagara; and bulbous glaciers and frost-cracked soils that show how cold and dry this land has now become. Fifty-five million years ago, Antarctica was warm, wet and brimming with life.
No rain has fallen in the interior of the Dry Valleys for millions of years, and there has been precious little snow. This is the coldest, driest, barest patch of rock on Earth. The life here took the form of giant mats that look as though they’re woven of some sludgy seamless material. In fact, they were made from microscopic cyanobacteria,
Dave Marchant calls this landscape ‘paralysed’. There has been no running water in Beacon Valley for fourteen million years. Most of the snow on the ground has blown in from elsewhere rather than fallen from the clouds. The wind may scoop and pit the boulders but it doesn’t move them. If I’d walked here a million years ago it would have looked like this. Ten million years ago, before humans ever walked anywhere, this is how this valley looked. It’s a window back in time.’
The tectonic forces that cause the rest of the world to buckle and warp have been subdued here for an extraordinary stretch of time. ‘You’re looking at the most stable landscape on Earth,’ said Dave. ‘Nothing even comes close. The Grand Canyon was carved in its entirety; the alps in New Zealand have risen to their great heights and all the while nothing happened here.’ I was awed by the sense that time was standing still there. And not just in the past but in the future too.
‘Are we crazy to spend six weeks out here? Can you imagine doing it?’ Yes, I could. I could imagine staying here much, much longer than that. I found myself envying him the serenity of this valley that time forgot. ‘I’m tired of rushing around,’ I said. ‘I’d like to stay here long enough to get bored, and then go beyond the boredom and see what’s really there.’ He seemed to understand. ‘It’s when you’ve been here for a while, when you really get in the zone, like a runner with a second wind, when the weather’s good and you’ve had a good day doing good science, you can just stop and listen and ask “what are you telling me?”’ Ask who? The landscape? I wondered if he was being whimsical again but I could see from his face that he was in earnest. ‘It does talk to you,’ he said. ‘Antarctica has this way of clearing your mind. Part of it is that there’s no distractions. They keep saying to me “why not just do day trips” but I say, “no, you have to be here, to be immersed in it. You have to feel the landscape—to start to feel like Antarctica. That’s when you can hear what it’s telling you.”’
Robert’s telescope would be picking up the faint afterglow of the Big Bang itself. For the first few hundred thousand years after the Big Bang the entire Universe glowed hotter than the Sun. A roiling plasma of negatively charged electrons and positively charged ions circled around each other, eager to join forces and become neutralised, and yet constantly breaking apart as soon as they united, because of the searing heat. And all was bathed in a brilliant blaze of light. Eventually, as the Universe stretched and cooled, the electrons and ions fell into each other’s arms to become the atoms that make up the stars, the planets, and us.10 And the light streaked out across the Universe, bearing the slightest, almost imperceptible traces of erstwhile lumps in the cosmic maelstrom, here the light a little denser, there a little more insubstantial. This faint glow is still out there, its elongated wavelengths now too far from the visible rainbow for human eyes to see.
the other kind of whiteout, the one that had apparently descended now without warning. In this variant, you could see anything in front of you quite clearly, but without any definition. Thick cloud somewhere high
above us was scattering sunlight so completely that all shadows were gone. The white snow underfoot and the white sky above were indistinguishable, empty of any kind of texture
Or maybe it’s not really about peace. There was nothing passive about this feeling. The world had shrunk, as if Antarctica had allowed itself to go from being intimidating to being intimate. And it had given me a deep sense of comfort that was almost overwhelming. This was the opposite of loneliness. It was also the opposite of being smothered. I felt utterly relaxed.
the continents could drift, that Antarctica spent much of its geological history wandering around the warmer parts of the world, before the grinding of the Earth’s tectonic plates took it to its current resting position at the South Pole. But we know that now. So perhaps all these fossils came from a time when the continent was basking in the warmth of the tropics. Well, not exactly. Geologists have traced Antarctica’s path through the ages, and it landed at its present position some one hundred million years ago—within the days of the James Ross ankylosaur. Even when Antarctica was sitting squarely at the Pole, it was a green continent, covered with forests and ferns and dinosaurs.
‘But warm-blooded animals only account for less than 0.00001 per cent of species on Earth. So for a scientist, if you take a statistical approach they don’t exist. They’re such a small proportion of life on Earth that they don’t really exist.’ Whoa. Statistically speaking warm-blooded animals, including humans, don’t really exist?
Eugene Domack, a sedimentologist from Hamilton College in Clinton, New York. He knew that the Peninsula was undergoing serious change right now, but he was also ready to take the long view. It was possible that this was just some perfectly natural local warming. Perhaps the Peninsula regularly experienced hot flushes that could disappear as quickly as they came. After all, we had only been acquainted with the region for a couple of centuries. Ice shelves might have been breaking and reforming repeatedly for thousands of years, with nobody there to notice.
the oldest Navy traditions. The previous night, the ship had sailed past the invisible line in the sea that marks the Antarctic Circle, and those of us who were first-timers had had to undergo an initiation ceremony. Originally this only applied to crossings of the equator, during which naval ‘pollywogs’ (neophytes) were transformed into ‘shellbacks’ (veterans) by means of the sort of humiliations that would make members of a fraternity turn pale.
This certifies that she Did, Boldly and Without Trepidation, Cross the Antarctic Circle at 66° 33’ South Latitude, 67° 36’West Longitude, aboard the Vessel Nathaniel Brown Palmer, entering the Treacherous and Unforgiving Reaches of the Antarctic Ocean. By so Doing and having Subsequently displayed proper Obeisance to King Neptune and his Faithful Lieges prior to Departing the Southern Reaches, She now Commands due Honor and Respect from all Persons, Whales, Seals, Penguins, Fishes, Crustaceans, Sponges, Insignificant Microscopic Creatures and other Denizens of the Polar Domains. (Rob studies insignificant microscopic creatures, which is probably why they made it on to the list.) Below all this, just above the signature of King Neptune, it added: She bears this Distinction with Pride for it is neither Lightly Undertaken nor Easily Attained.
All of this ice had come from the land, from snow, turning to ice, turning to glaciers, spilling into the sea, floating, flexing and finally breaking off. But the water, too, was freezing. Here it was slushy with grease ice, or frazil, which slithered against the ship’s hull; there it was so still that it had already begun to form pancakes, like frozen water lilies, decorated with streaks of snow. As we continued, the sea ice became more abundant, and thicker. The Palmer’s bow now smacked with pistol cracks as she performed a stately slalom through the pack. And overhead snow petrels wheeled, silhouetted against a slate grey sky, graceful as swallows.
sorted through his newly retrieved samples to see what the mud had to say. And what he found was as shocking as the Larsen B’s almighty breakdown. As far back as the record could show him, all the way to the end of the last ice age 10,000 years ago, the ice shelf had been fully intact.37 The spectacular collapse of Larsen B was completely new. This was deeply troubling news. It seemed to confirm what many meteorologists suspected—that the warming of the Peninsula really is down to our activity.
making their mark on the Antarctic Peninsula. There was one shred of comfort. Floating ice already displaces water, so when ice shelves disintegrate they don’t make sea levels rise. But they now looked like a serious warning sign, a shot across our bows. ‘The Peninsula ice shelves really are the canary in the mine,’ Gene said. ‘And if the canary goes, you have to be worried.’
On the eastern side is the East Antarctic Ice Sheet, by far the larger of the two, a mighty behemoth that contains more than 80 per cent of all the ice on Earth.
Though its average thickness is more than a mile, most of its base still rests safely on high ground and most of its ice creeps only sluggishly from the centre to the sea. It has been around for tens of millions of years.
Since its coastline tracks the Indian and Atlantic Oceans, the eastern ice sheet is relatively easy to reach by ship or plane from New Zealand, Australia, South Africa, and the tip of South America. On the west, however there is . . . nothing. The coastline of the West Antarctic Ice Sheet faces the broad, empty expanse of the Pacific Ocean. No nation can reach it simply by sailing south and it has not one single permanent scientific station. Most of the ice sheet lies beyond the normal reach of any existing Antarctic operations. The west of Antarctica is truly Earth’s final frontier.
The rock on which the West Antarctic Ice Sheet rests isn’t high like the east. Instead, almost all of it lies below sea level, and some is ten thousand feet deep. So deep, in fact, that if it weren’t for the ice there would be nothing in the west but ocean, and a smattering of small island archipelagos.
That meant we were crossing over into the ice stream. On one side, the ice was moving perhaps several feet per year. On the other, it moved that same distance in a day. On the outside of the margin the ice was resting, on the inside it was racing, and the area between was being ripped apart with the strain, creating such extraordinary patterns of crevasses on the ice
That evening the light was lovely. I borrowed some skis and went out a few kilometres beyond the camp. Apparently there hadn’t been much wind lately; the sastrugi were smooth and low. This was a new variant of the familiar ‘flat white’ of the East Antarctic plateau. Though the air here was 5°F and dry enough to scrape the skin, it was still noticeably damper than the dry desert of the east. There was moisture enough in the air to coat guy ropes with hoar frost. And the crystals on the surface were big and bold and flashy. They glinted in the slanting sunshine, as if someone had scattered handfuls of diamonds over the snow.
Beneath Antarctica’s mantle, in the deep dark places where ice met rock, it seemed that there were entire districts of hidden, liquid lakes…they were buried under miles of ice and hadn’t seen daylight for hundreds of thousands, perhaps millions of years. But researchers knew they were there thanks to the way ice can’t help but betray its roots.
He and George have carefully charted different parts of the channel systems in the Dry Valleys. They have worked out which cuts through what, separated out the older features from the younger, used volcanic ashes to date different layers and figure out what happened when. They agree that this landscape is incredibly old. There was probably a series of floods, but the last one took place somewhere between twelve and fourteen million years ago, and almost nothing has happened since.
Ross Sea is one of the key parts of the global conveyor belt, an interdependent set of ocean currents that carries heat around the planet in a complex pattern that evens out some of the imbalances between the overheated tropics and the frozen poles. As sea ice forms here, the remaining water becomes saltier, and heavier, and sinks down to set the conveyor in motion. Throw in a sudden lens of freshwater on the top and you could jeopardise the whole thing.
And even when all of the ice finally does melt that will not be the end of Antarctica. The Sun is naturally warming as it ages, and some distant day, perhaps millions of years in the future, the white continent will turn green again no matter what we do. When this happens, as it must, we humans will probably not be there to witness it. But someone or something else surely will.
