12:34 pm
parts of antarctica a woman faster than anywhere else on the planet this is having an effect on wildlife and is altering deep ocean currents which regulate the world's climate from the poles to the equator. as antarctica's ice melts we're seeing global sea levels rise and unpredictable changes to with world wide. and this earth rise special we visit the world's most remote continent to see the affix of climate change firsthand. i'm tired as an obvious meaning the next month on this research vessel travelling around antarctica with a group of scientists who are trying to understand how the changes taking place there will affect us all.
12:35 pm
a jewel in the expedition in hobart australia the russian research ship academy contrition a cough has been hired by the swiss polar institute to circumnavigate antarctica. it will be a floating lebar tree from which fifty five scientists will do twenty two different experiments. david walton has been. sitting antarctica for more than fifty years and is the expedition chief scientist. because the antarctic and the southern ocean actually influence the whole of the global weather system and all the currents in the oceans it matters to everybody it also matters if they're on top of it begins to melt as far as world sea level is concerned it's a larger source of new water out it to the oceans in the world so even if you live somewhere a long way away if you're low lying on the coast the antarctic masses to. the
12:36 pm
voyage will take us two and a half thousand kilometers south from home to the edge of antarctica. will then travel five thousand kilometers east making stops at a number of islands. then after a month at sea he will return to port in southern chile. first we must cross what are known as the furious fifty's in screaming sixty's latitudes nine for they ferocious with us. we face hundred kilometer hour winds and ten meter away. it's a nearly reminder of the potent energy of the oceans. as we sail self the air and sea become colder.
12:37 pm
then on the sixth morning we wake up to sea ice. soon we're forced to navigate around icebergs some the size of a football pitch others are more than one hundred kilometers long. then fire. we arrive at the minutes in antarctica. and he lays in the powerful winds coming in off the glass and dropping down into the sea this is the one place on the planet at sea level and it's certainly playing up that reputation tonight. the mets glassie a fascinates scientists because in two thousand and thirteen an enormous chunk around seventy five by thirty five kilometers broke off after it was not by
12:38 pm
a large iceberg. this is dramatically changed the flow of ice in the area it's also exposed large areas of ocean floor to study for the first time. the weather comes right and the ship docks it's balanced against the glass. this gives the scientists a stable platform to begin their work. this suffering yeah exactly. say is a biologist and in charge of an ambitious project something out of a science fiction yeah it's quite amazing. so much here on the whole of the swiss army knife the swiss army knife and time discovered yes exactly this time through some things ok lights. so well i see something you must know his own is cameras basically we work very hard to finish
12:39 pm
and cameras. digital still camera one fork a camera here basically we are interested. so very soon. along we always call them along with the the from . the team expects to see a vertical wall of ice dropping five hundred meters from the surface but instead there's a surprise. they discover a huge underwater cavern been in this part of the glass in. the sea water is warmer than expected and this is unusual evidence of now we're really close to the ice and discovered that it was really nice everything was going to melt away with still going to a lot of. yeah completely rotten we were not expecting. a
12:40 pm
lot especially in this depth so far into the. warmer ocean currents and now flowing further south towards antarctica scientists believe the kind of melt we've seen here who contribute more than a major to global sea level rise by the end of the century and up to thirty meters of the next five hundred years. glass is like rivers of ice so when the ocean water warms and they melt the remaining ice mousse faster towards the sea a team of glaciologists want to see how this is happening and ice cores from next to the glass is age seven meters down they find something unexpected.
12:41 pm
this is the bubbles in. this i think they probably can raise can time water a liquid salty water. finding so water here suggests warmer ocean currents are having an impact possibly weakening like last year from beneath. all thankfully copters return and the ice cores are loaded on board thanks. to back on the ship they placed in a giant freezer. the history of this size is the first cause is not. going to the continent and then it depth the pressure of the snow above it is compressing compressing into at a depth of about sixty meters this will be so compressed that inform solid ice one of the principles of science is that while that's happening the air. from the atmosphere that was in it is in the snow when it is being locked into the is these
12:42 pm
bubbles forming right. gradually as we get deeper under more and more pressure. get isolated and you see these little bubbles and that's when we get deeper into the us because we want to look at carbon dioxide concentrations back thousands hundreds of thousands of years it's puppets of the atmosphere that we get into so you see that process starting here. few our schools have been taken from this part of antarctica so there's little specific information about how the climate is changing but it's hope these samples will help fill this gap. further east live the balun a islands for most of the year they're locked in sea ice but a visit like this in summer means a team of scientists can dredge the ocean floor and i've been drafted in to help. them. to get. a certain amount of the rocks.
12:43 pm
from the bottom have come up with a name so it's pretty much say it is this far lost out of the rocks in the mud and then after that they can get. places that have come up with. a particular interest of those that take carbon from the environment by locking it away in their shells these they end up being buried in the sea bed when they die. another ten times. over the last hundred years carbon dioxide levels in the atmosphere have risen dramatically largely as a result of al burning of fossil fuels. the role these creatures play to counteract this needs to be better understood and incorporated in climate change models. something is the word. with more than
12:44 pm
a centimeter. this. time skeletons are made of carbon that these guys here the impressing worms and these tiny things here. that don't go by much but there are hundreds of little combinations animals that. will fall over the. balance. system. one source at the creatures are taken to the lab and photographed. the sea mouse is a notable catch so to this brittle star another un kills itself measuring around fifty centimeters across. many of these creatures will be
12:45 pm
preserved and after the expedition the d.n.a. will be analyzed giving the researchers detailed data about the distribution and diversity. serving picked over the summer look for anything of interest there are stuff looks like from this any one thing to want to ship like this in the weeks or ballast so. the robust team also tune their cameras on life on the sea floor. at a depth of nine hundred meters they take samples of cold water corals and a wide dry. the species. they also take see them and course these will give them clues about what's being buried in the ocean floor and how it's changed over time.
12:46 pm
but it's lighter in the dog than extraordinary observations. we have this sistar more precisely a brittle star crawling on of sea floor which we believe that eight or scavenger but certainly have a fish just crawling it just in the fish with a poison we don't know yet because that's just me you would ever seen that before and it just been a fish live on the side it's only this real star just really it's tried to eat the fish which can swim in it at a speed watch watch one much faster than any kind of of sistar you can call it a sea floor so that's quite amazing just to see that that's that that's the when you. close analysis of the footage reveals ten examples of the spot hevia. these are two of the most abundant species living in antarctic waters
12:47 pm
and interaction of this nature has important implications for understanding climate change only column inches can saying to this fish then chance fulton done nothing to do both and will do isn't an alternative variant there we do know quite a lot of organisms and he didn't you know he's innocent of very efficient and poisoning the brain and the icing this is the case but we still have to to do a bit more new science we've made a discovery we're now in is that we have to to do further research to really understand what we see. we're. antarctica has the cleanest on the planet and at each stop on the voyage atmospheric scientists julia shamali has used a mobile kids to take some pills. she's also packs a suite of instruments into a shipping container on board i do has
12:48 pm
a good effect your the big read the book is out here today declan and thanks very much why did the stuff pass of him why he's so interested there was so actually in particular we're interested in the tiny particles that are in the air we call them aerosol aerosol particular and they have very important for the water cycle and because they form clouds without these tiny particles we would not have any clouds in our atmosphere so it would never rain. earth would be a completely different planet to see if the hot ticket spent ten full droplets on not that we use this machine and then a cloud machine here that you know we should make here are some are making our own cloud in here so it's very important floss to understand politics clouds formed before the industrial revolution before humankind actually started burning fossil
12:49 pm
fuels in large amounts. because it makes a big difference for our climate for the clouds and for the hydrological cycle in general. climate change models a generally better at predicting variations in temperature rather than precipitation let's hope the data from this experiment will mean that. as the ship continues east we come across more c.-r. ice. without crunching our white through the arch for. if you come across the sea ice flies i want to drop a camera down to say can have a look at the balance doing down there it's really quite remarkable. luckily for us anyway the balance of this twelve thousand ton ice breaker rides up all over the ice for i'm showing there as well that. the power from the chamber through the sea ice. ok comes another enormous chunk
12:50 pm
let's see how this one fears of the bowels of the academy they called pushed out of the so i. the next opposite one of the smallest islands on this leg of the voyage just five football pitches inside scott on and is washed over by y. . and in stormy conditions at sixty seven only by helicopter. its two winds whip for seabirds tánaiste that lie can and must do grow in the cracked volcanic rocks. hopefully with the most of the soil we're going to find into the rivers and that you just not hear of how the animals cope through not me i guess climate change the past mostly natural but also
12:51 pm
how they my belief in it definitely you know and facing the future. before we can be flown off the island back to the ship there's a sudden change in the with. the helicopters clearly being grounded on the ship they're not able to return to the yacht and to pick us up and we have enough equipment with us. taynton and rations for four days so i don't there's a great concern there but it does. is that you thinking about how you could possibly survive on an island like this so revived recently well. fortunately the way the lifts just long enough to fly us off the island and was saved to me the having to find out. back on the ship the samples are dried it's hoped any living things will drop out of this lichen is also examined
12:52 pm
and within it there's a discovery smaller than a pinhead this is the first time this tiny might has been found here similar mites have been found in other parts of the continent but it's likely that this is a new species something a new d.n.a. tests after the expedition can confirm the landscape is incredibly old so you know probably started off one hundred eighty million years ago would've been a tropical rainforest and it's now looks like it does both sides and so these are some of the few things that are probably managed to hang on that long and so now there are some of the more successful organisms that live here. where. the teams made to discuss their next move from satellite images it appears the next island on the route peter the first is surrounded by sea ice this will make a visit difficult. instead some of the scientists call for the voyage to divert
12:53 pm
they've spotted clear water around a coastal area which is normally docked in sea ice it's a rare opportunity for them to attempt to visit. the ship's course is changed and we arrive at mt siple it's one of the continent's tallest and most isolated volcanoes rising more than three thousand meters from the sea. we scout the area and find a large number of a daily pinguin. but it's certainly come to in touch with to see them in their natural environment see what an extraordinary animal they are and just how incredibly tough they are living in the sea they're going to watch. these valleys and then mystic on the top. by the time we return to the ship it's late in the evening. but at this time of
12:54 pm
year at such high latitudes it doesn't get dark. instead there's a long and spectacular sunsets. the following morning we fly back to mt sinai port listen one percent of antarctica is ice free making a place like this prime real estate and nice thing. many of the chicks have been left to fend for themselves while their parents go to sea to catch currall the pinkish color of the shrimp like food often ending up staining their front us as far as we know scientists have never visited this colony before so the group we're with wants and i how large it is and whether there's any other species living here we have behind me a whole lot of adele leaping going on that's going to turn around here show you this chip here he is looking
12:55 pm
a bit odd because he's losing his baby feel this is just a few months old isn't safe he's very friendly. when the parents return there much in demand sometimes from their own offspring but frequently from other hungry birds hoping for a feed it's late in the season and many are exercising their wings and preparation to leave. nothing about the other three virgins they give you this sort of canary in the cold while indication as to what's happening in the southern ocean and this is the thing if entirely big. this colony appears to be thriving but on the antarctic peninsula to the east of here it's a different story. the area is warming faster than any other place on the planet and colonies of our daily penguins like these have been abandoning their nesting sites and moving south perhaps in search of colder locations certainly up sitting
12:56 pm
many hundreds if not thousands of years of breeding behavior. over the previous weeks we've been to some extraordinary places and seen dramatic evidence of climate change it's change many of the scientists feel should be ringing alarm bells in the rest of the world. in the same way that the antarctic sea ice is actually changing in terms of its distribution pattern the sea is warming off the antarctic peninsula the glaciers are retreating out thick sea ice is at its lowest yet known these are all indications that the world as a whole is warming and that we need to be concerned about the future we certainly know enough to say we need to act now we should act that yes that they figure to speaking there's not much time. action into the future i think. where we're
12:57 pm
very clear about this. week about. that of knowledge we're still have some work to do we're already kind of learning new. experiments new it's additions to try and really understand what you see. the expedition is collected tens of thousands of samples and millions of megabytes of data. for these scientists who will return to their nabs around the world these years of work here. we're just scratching the surface to understand how antarctica is the southern border so significant when it comes to the broader issues of climate change and and really when the earth is going to go where our climate is going to go in the years ahead. the scientific findings made on this forward will add weight to what's now overwhelming proof that our planet is warming and that climate change is
