{1}{1}25.000 {2486}{2536}This is the hut at Cape Evans {2538}{2641}where Captain Scott|and his party spent the winter of 1911. {2643}{2695}The freezing Antarctic temperatures {2697}{2760}have kept everything exactly as it was - {2762}{2856}food, equipment|and, perhaps most poignant of all, {2858}{2910}clothing and bedding on the bunks. {2912}{2999}It's as though|the explorers left yesterday. {3011}{3064}And this is how it was {3066}{3195}around that same table|on June 6th, 1911, Scott's 43rd birthday. {3197}{3260}He and his team wintered here {3262}{3330}so as to be ready,|as soon as the sun reappeared, {3332}{3383}to start the trek to the pole. {3404}{3494}They lightened the long dark days|with their own entertainment. {3496}{3566}But these were serious-minded men. {3568}{3655}For some, reaching the pole|was of secondary importance. {3657}{3723}They had come to make scientific discoveries {3725}{3813}in geology, biology, glaciology, meteorology - {3815}{3897}and they had a surprisingly|well-equipped laboratory. {3985}{4052}And that is still here, too. {4147}{4234}Photography was in the hands|of Herbert Ponting. {4236}{4315}He took cine film|as well as still photographs. {4317}{4376}He had his own cramped darkroom {4378}{4452}in which to develop and print|his huge glass plates. {4498}{4585}They had with them|large stocks of tinned food. {4603}{4705}We now know that this was not nearly|as nutritious as it was supposed to be. {4707}{4758}That and other vitamin deficiences {4760}{4844}contributed to the disaster that was to come. {5274}{5364}As they waited, they knew that,|further along the coast, {5366}{5416}the Norwegian Amundsen and his team {5418}{5479}were waiting to try and beat them to the pole. {5523}{5580}0n 1st November, at the beginning of summer, {5582}{5630}Scott and four companions {5632}{5766}left this hut and set off|on the 800-mile march to the South Pole. {5801}{5878}They wore clothes of wool|and cotton like these. {5880}{6002}They travelled on long wooden skis|with simple bindings, {6004}{6090}and they transported|their equipment and food {6092}{6153}on sledges which they pulled themselves, {6155}{6283}having decided against the dogs|which Amundsen was using. {6285}{6367}They reached the pole on 17th January, {6369}{6467}only to find that Amundsen|had got there 34 days before. {6469}{6557}0n the way back,|they encountered dreadful weather, {6559}{6597}ran short of supplies {6599}{6684}and died in their tent|of starvation and exhaustion {6686}{6739}11 miles from a food depot {6741}{6827}and less than 100 miles|from the safety of this hut... {6893}{7004}Today, some 80 years later,|a great deal has changed. {7006}{7103}Modern fabrics keep you warm|during the worst of conditions, {7105}{7204}satellites in the sky|make communication and navigation easy {7206}{7270}and, almost every day in summer, {7272}{7329}an aircraft takes off from the ice near here {7331}{7385}and flies directly to the pole. {7610}{7754}Captain Scott marched for 79|exhausting, back-breaking days {7756}{7798}before he reached the pole. {7800}{7880}This plane will make|exactly the same journey {7882}{7937}in less than three hours. {7939}{8028}And today alone, there are|four other flights like this. {8079}{8138}As you fly along Scott's route, {8140}{8203}it is not only the sheer distance|that impresses you, {8207}{8298}it's also the appalling|difficulties of the terrain. {8300}{8425}At first, Scott used a combination|of motor sledge, ponies and dogs, {8427}{8510}but after 409 miles he abandoned them all. {8514}{8606}Thereafter, he and his men|hauled the sledges themselves, {8608}{8676}each man pulling 90 kilos. {8775}{8888}The decision not to use dogs throughout|was probably their undoing. {8890}{8937}Amundsen, by doing so, {8939}{8986}made the journey much more quickly {8988}{9040}and with much less physical effort. {9042}{9106}So when Scott and his companions|reached the pole, {9108}{9178}they found Amundsen's abandoned tent|already there, {9180}{9302}and inside it a note for Scott|to deliver to the King of Norway {9304}{9379}should Amundsen himself fail to return. {9553}{9638}Scott, when he arrived at this exact spot {9640}{9749}and found the Norwegian flag|already planted by Amundsen, {9751}{9789}wrote in his journal: {9791}{9891}"Great God, this is an awful place." {9893}{9931}And so it must have been {9933}{10027}to those five exhausted,|bitterly disappointed men, {10029}{10107}with the dreadful return journey|still ahead of them. {10115}{10178}Today, some 80 years later, {10180}{10239}neither explorer would recognise the place. {10315}{10423}This summer, over a hundred|scientists and support staff {10425}{10547}will live and work protected|from the worst of the weather {10549}{10589}by this dome. {10614}{10694}Beneath it are smaller, insulated buildings, {10696}{10782}for the dome by itself|is not sufficient protection from the cold. {10825}{10896}It stands 16 metres high. {10898}{10944}It's like a space station, {10946}{11030}an isolated capsule|floating on slowly-moving ice {11032}{11097}nearly 3,000 metres above sea level. {11168}{11224}All supplies for the pole station {11226}{11274}have to be brought in by air. {11327}{11386}Even in summer, it is so cold {11388}{11453}that the supply aircraft,|after they have landed, {11455}{11528}have to keep their engines running|to stop them from freezing. {11601}{11669}The fuel they bring is transferred {11673}{11771}into vast bladders which will|last the station through winter. {11868}{11942}The South Pole is the best place on Earth {11944}{11990}to observe the heavens above. {11992}{12071}The atmosphere is totally clear|and free from pollution, {12075}{12191}and the stars don't disappear|below the horizon as they do elsewhere, {12193}{12258}so they can be observed continuously. {12286}{12352}(H0WLING WIND) {12506}{12563}Working in Antarctica {12565}{12623}demands a special kind of scientist. {12625}{12673}You may have the most brilliant mind, {12675}{12717}but that may be of little use {12719}{12806}if you can't pitch a tent|or restart a diesel engine. {13151}{13235}Most of the stations are built|on the edge of the continent, {13237}{13291}like the Australian base at Mawson. {13293}{13375}They stand on rock instead of ever-moving ice. {13549}{13633}There are other living creatures|with which to share your life. {13635}{13727}35 miles from Mawson|are Emperor penguins {13729}{13802}which also, like you, will sit out the winter. {14024}{14085}When the last supply ships have left, {14087}{14159}the wintering crews|will see no other human beings {14161}{14220}for six whole months, perhaps more. {14264}{14334}They must find a way of living together {14336}{14438}in a place where, for some of the time,|there will be no morning, no evening... {14444}{14479}and no escape. {14483}{14565}Routine is all-important|and there's plenty to do - {14567}{14614}not only scientific work {14616}{14687}but all the jobs necessary|to keep the station running. {14689}{14773}Looking after the dogs|is a much sought-after job. {14775}{14860}It's refreshing to see|living things other than humans. {14923}{15001}Food becomes hugely important... {15003}{15080}and the cook is one of the most critically|watched members of the community. {15531}{15643}Most bases have at least|a year's supply of food in reserve {15645}{15685}in case of emergencies. {15732}{15844}And most also have a building|away from these living quarters, {15846}{15883}fully stocked with food {15885}{15960}in case of the worst disaster of all, a fire. {15996}{16082}For no humans without shelter,|in conditions like this, {16084}{16149}could survive for more than a few hours. {16217}{16281}As winter advances, the day shortens, {16285}{16402}the sun skims closer to the horizon|and eventually drops below it. {16404}{16477}Now, there will be|little or no sunlight whatever {16479}{16528}for 37 days. {16632}{16672}Midwinter Day. {16674}{16780}Mawson Base, as every other,|marks it with a great party. {16826}{16900}Entertainments that have been|practiced for weeks in secret {16902}{16948}are now performed in public. {17236}{17310}(INDISTINCT SINGING -|"WALTZING MATILDA") {17541}{17641}# You'll come a-waltzing,|Matilda, with me... # {17890}{17966}0utside, the darkness is broken {17968}{18054}only by one of nature's|most extraordinary spectacles - {18056}{18148}the Southern Lights,|the "Aurora Australis". {18693}{18797}As the sun returns,|so do the Adelie penguins. {18869}{18972}This traditional colony|is only a mile from Mawson Base. {18974}{19036}It's now one of the best studied of all. {19061}{19135}A wire-fenced corridor|with an electronic beam across it {19137}{19221}ensures that some of the birds,|as they go to and from the sea, {19223}{19286}are automatically counted and weighed. {19322}{19399}But a few must still be caught|and measured in detail {19401}{19464}to check the colony's progress. {19894}{19957}Some are given prominent markings {19959}{20002}so that they can be identified {20006}{20100}among their near-identical companions,|even at a distance. {20168}{20244}It is, it must be said, rather disfiguring, {20246}{20300}but it will disappear at the next moult {20302}{20374}and it hasn't lessened|the affection of the bird's partner. {20677}{20756}Dogs have been used here|since Amundsen's day, {20758}{20809}but dogs are ecological aliens {20813}{20878}and it has been decided that they must go. {20880}{20928}Many regret that. {20930}{20972}Dogs are great companions {20974}{21053}and they can detect one of the major|hazards of Antarctic travel - {21055}{21155}a snow-covered crevasse -|and stop before they all fall in. {21157}{21238}No motorised sledge can do that. {21257}{21361}This team will be sent|to Minnesota in the U.S. {21363}{21446}Its departure will mark|the end of a great chapter {21448}{21526}in the short history|of mankind in the Antarctic. {21638}{21677}They will be replaced {21679}{21734}by motorised "quikes". {21835}{21929}There is a limit to the amount|of fuel such vehicles can carry, {21931}{22018}so they can't cover|such great distances as a dog team. {22020}{22072}But they do travel faster. {22102}{22167}It used to take two days with dogs {22169}{22223}to reach Mawson's Emperor colony. {22225}{22281}Now it's only a three-hour drive. {22283}{22404}All year, even throughout winter,|scientists visit this colony {22406}{22487}to monitor its progress|as part of a long-term study. {23047}{23148}There is a serious purpose|behind this rugby tackling. {23152}{23219}The bird is to be fitted with a transmitter {23221}{23303}that will send regular signals|by way of an orbiting satellite {23305}{23390}to a monitoring station in Tasmania. {23392}{23476}It too is given an identifying mark. {23641}{23695}If this bird is like others, {23697}{23802}it is now setting off|on a 100-mile march to open water. {23804}{23851}And when it gets there {23853}{23965}it will dive to an astonishing|depth of 450 metres to catch fish, {23967}{24060}all the time recording information|to say where it is. {24098}{24151}Hundreds of miles to the north, {24153}{24248}a grey-headed albatross is|providing similar information. {24250}{24316}It too has a transmitter on its back, {24318}{24410}which revealed where it collected|the food in its stomach {24412}{24484}that it's now bringing back to its hungry chick. {24618}{24653}It belongs to a colony {24655}{24752}that has been studied|for the past 15 years by a British team. {24756}{24857}The old method of weighing birds|was with a simple spring balance. {24933}{25004}But now the researchers use a new device. {25007}{25129}Electronic scales are concealed|inside a fibreglass nest. {25206}{25310}From now on, there will be|no need to manhandle the chick {25312}{25355}just to get its weight. {25392}{25472}The scales transmit|a reading every ten minutes {25474}{25592}to a nearby hut with a scientist|and recording apparatus. {25606}{25667}This shows that one of the parents brings {25669}{25822}500 grammes of squid, fish, lamprey|and krill to the chick every three days. {25824}{25888}And signals from the satellite {25890}{26001}reveal that the adult travelled|several hundred miles to do so. {26272}{26322}To film this series, {26324}{26363}we drew heavily on the discoveries {26365}{26426}made by scientists all over the continent. {26430}{26492}Guided by their satellite data, {26494}{26570}we aimed, among other things,|to record in pictures {26572}{26658}just what those albatross|and penguins did in the open ocean. {26660}{26757}That involved developing cameras and lenses {26759}{26821}to cope with these hostile conditions, {26823}{26896}and finding cameramen|who could cope with them, too. {26928}{27008}Swimming in the open ocean|in near-freezing seas {27010}{27062}may be second nature to an albatross, {27064}{27122}but it's a daring thing for a cameraman to do. {27268}{27316}The reward for him is sights {27320}{27378}that have never been filmed before. {27496}{27567}0n board our ice-strengthened vessel,|the Abel-J, {27571}{27681}we carried boats,|diving gear and video apparatus. {27683}{27744}As well as free-diving cameramen, {27746}{27846}we had remotely-controlled cameras|mounted on the inflatables. {27992}{28092}0ne of our priorities|was to find a swarm of krill. {28094}{28157}After weeks of searching, we did. {28311}{28383}And so had a pair of humpback whales. {28555}{28666}The remotely-controlled video cameras|gave us unique pictures. {28734}{28815}They recorded in unparalleled detail {28817}{28885}the whole of the whales' fishing technique {28887}{28947}from the moment they released|their curtain of bubbles, {28949}{29010}hemming in and concentrating the krill... {29051}{29099}to the final catch. {29384}{29492}We also had another vessel,|a small, steel-hulled yacht, {29494}{29533}the Damien II. {29535}{29590}She had a retractable keel, {29592}{29665}so could operate in waters only a metre deep {29667}{29767}and go into shallow bays|where no other vessel had been before. {29972}{30054}Jerome Poncet is the skipper|and owner of the Damien. {30056}{30118}With his biologist wife, {30120}{30158}he has spent ten seasons {30160}{30248}exploring every cove and bay|on the Antarctic peninsula, {30250}{30318}and knows them in a way no one else does. {30700}{30770}He was able to land camera teams {30772}{30849}on tiny, remote and uninhabited islands. {30861}{30965}Each night, a radio hook-up linked|all the camps and the ships, {30969}{31083}which were often separated|by hundreds of miles of ice or ocean. {31085}{31165}{y:i}Abel-j, this is Bailey Head|{y:i}reading you loud and clear. {31167}{31278}{y:i}This is Abel-j.|"To confirm your message" - {31280}{31390}{y:i}two tents badly damaged,|{y:i}one tent, broken pole. Over. {31462}{31529}A camera on a jib arm. {31531}{31628}It gives a splendid high-angle view|of a penguin colony {31632}{31704}and enables you to move alongside {31708}{31761}an individual penguin on its perambulations. {31763}{31857}But the whole thing weighs 120 kilos, {31861}{31931}and carrying that over snow fields and cliffs {31933}{32022}reduces even the strongest|camera team to gasping wrecks. {32176}{32249}To get unbumpy pictures on the move, {32251}{32378}Paul Atkins used a special mount|called a steadicam. {32380}{32478}That way, he was able to move|smoothly into really close quarters {32480}{32582}with tricky - and dangerous - subjects,|such as fighting fur seals. {32977}{33071}Blizzards often brought|land-based operations to a halt, {33073}{33192}but there was still work|that could be done, underwater - {33194}{33261}if you can dig out the air cylinders. {33272}{33339}Diving under the ice is very different {33341}{33383}from doing so in the open ocean, {33385}{33434}as cameraman Mike Degruy explains. {33468}{33518}{y:i}I'm generally a fair-weather diver. {33520}{33605}{y:i}I like warm weather, sunshine,|{y:i}palm trees and hammocks. {33607}{33691}{y:i}I jumped into a seal hole,|{y:i}pushing the ice away as I entered, {33693}{33733}{y:i}and they handed me my camera. {33735}{33776}{y:i}Surprisingly, I wasn't too cold, {33778}{33882}{y:i}except around my mouth,|{y:i}which instantly froze and became numb. {33912}{33988}{y:i}Suddenly everything was quiet|{y:i}and I found myself {33990}{34068}{y:i}looking at easily one|{y:i}of the most extraordinary scenes {34070}{34135}{y:i}I had ever, ever experienced. {34184}{34284}{y:i}I dropped down through a hole|{y:i}and was completely surrounded by ice, {34286}{34349}{y:i}a tunnel maybe 20 feet across. {34351}{34442}{y:i}Everything above me|{y:i}on the land was roaring with wind. {34444}{34512}{y:i}Down there there was absolutely no sound {34514}{34584}{y:i}except for the distant trills of Weddell seals. {34793}{34873}Weddell seal researcher Amal Ajmi {34875}{34917}works underwater, too, {34919}{34963}but she doesn't get wet. {35051}{35128}She makes her observations from a capsule {35130}{35197}suspended 10 metres beneath the ice. {35205}{35296}From there, she records|the sounds of the seals {35298}{35379}while noting on a tape recorder|their movements. {35401}{35471}{y:i}There's a lot of activity, a lot. {35611}{35739}{y:i}There's a pair next to the hydrophone,|{y:i}probably the loudest animals. {35789}{35917}{y:i}There's one single seal that is on my left {35919}{36018}{y:i}and it seems to be watching|{y:i}the mother and pup {36020}{36072}{y:i}that were near the hydrophone. {36311}{36441}0ther researchers have been studying|a colony of Emperor penguins for many years. {36443}{36524}They watch them underwater|from within a protective cage, {36526}{36562}for where there are lots of penguins {36564}{36628}you can expect|to find dangerous penguin hunters - {36630}{36687}leopard seals or killer whales. {36759}{36816}And this is a leopard seal, {36818}{36890}a huge animal, nearly four metres long. {37021}{37095}A remotely-controlled camera properly placed {37097}{37169}will record the exit of the fleeing penguins. {37460}{37536}But even out of water|they are not out of danger. {37550}{37611}Another leopard seal waits for them. {38237}{38304}Many people reckon that the leopard seal {38306}{38394}is the most dangerous killer|in Antarctic waters, {38396}{38436}and that it would be suicide {38438}{38481}to get in the water with one. {38483}{38570}But the camera team were|determined to film them hunting {38572}{38628}without the encumbrance of a cage. {38630}{38732}Peter Scoones and Doug Allen|were the first to try. {38772}{38854}{y:i}I'd been underwater with all|{y:i}the other species of southern seals, {38856}{38900}{y:i}so I had this feeling {38902}{38981}{y:i}that the leopard seals|{y:i}wouldn't actually attack us, {38983}{39043}{y:i}at least not without some warning. {39081}{39162}{y:i}We thought we could recognise {39166}{39217}{y:i}if their behaviour did slip over the borderline {39219}{39284}{y:i}from curiosity to aggression. {39528}{39587}{y:i}It produces a fair rush of adrenalin {39589}{39629}{y:i}when a 12-foot seal appears {39631}{39764}{y:i}and almost takes the entire front|{y:i}of the camera into its mouth. {39968}{40034}{y:i}You have to feel sorry|{y:i}for the young penguins. {40036}{40131}{y:i}They just don't stand a chance.|{y:i}It's like a cat with a mouse. {40185}{40221}"And here I was" - {40223}{40289}{y:i}the cat owner|{y:i}being presented with the prey. {40484}{40545}{y:i}But I shouldn't deny the sheer excitement {40547}{40587}{y:i}of filming so intimately {40589}{40643}{y:i}one of Antarctica's top predators. {40764}{40829}{y:i}This drama is a symbol of Antarctica {40831}{40898}{y:i}and I'll always count myself|{y:i}privileged to have seen it. {41161}{41227}It's still less than a century {41229}{41333}since the first man set foot|on the Antarctic continent, {41335}{41423}yet today, hundreds of scientists|live and work here, {41425}{41477}winter and summer. {41479}{41537}Increasing numbers of tourists arrive {41539}{41574}and, every year, {41576}{41668}modern technologies|make it increasingly easy {41670}{41719}for people to survive here. {41721}{41835}Yet there are still very few|footsteps in the Antarctic snow. {41837}{41931}Mining has been banned|for a further 50 years {41933}{42027}and the Antarctic Treaty|remains relatively effective. {42033}{42092}At a time when it's possible {42097}{42195}for 30 people to stand|on the top of Everest in one day, {42197}{42331}Antarctica remains a remote,|lonely and desolate continent, {42335}{42384}a place where it's possible {42386}{42477}to see the splendours|and immensities of the natural world {42479}{42519}at its most dramatic, {42521}{42626}and to witness them|almost exactly as they were {42628}{42742}long, long before human beings|arrived on this planet. {42744}{42798}Long may it remain so.
