5 Stories That'll Give You the Chills

[Music] the ice is typically around five centimeters when I skate on that sound you hear is actually a combination of two sound it's their sounds from crack striking beneath me and the vibrations within the ice plate itself it sounds like it's something supersonic meet Morten Einar hi I'm Morten Einar he's a mathematician who enjoys riskier hobbies than most I be skating on thin ice for 40 years when he's skating though he's also listening consider the ice the higher the pitch just about when the ice is to break and that would be about three centimeters the pitch is at the highest see their supposedly highest note on the soprano see wooden relies on his knowledge as a mathematician to calculate the thickness of the ice it's flexibility and it's temperature many people tend to freak out when they see a skating on thin ice but I couldn't be more calm because I know what I'm doing sometimes the ice is perfectly clear and I can see fish blow even a beaver and also free divers swimming under the eyes when Morten first started there wasn't any physics or scientific information to explain how thin ice skating is possible he studied the ice for ten years every winter to explain the phenomenon I observed three things with a thin ice one is that the ice bends and the thinner it is the more advanced the arms needs to be flexible to support you second the first crack is a true warning signals then I know the ice is spent and when it gets even thinner more first of all finally the ice gives sonorous tone beautiful eerie tone which immediately tells me how thick the ice is it's called the coincidence frequency and it can be calculated mathematically wooden has skated on over 1,800 bodies of water in North America Norway and Central and Eastern Europe I love skating for the excitement and challenges it brings it's an opportunity for master nature to come together and make it understandable for me I've been skating most of my life and I always look forward to next week [Music] [Applause] [Music] this incredible glacier located in Alaska is a popular tourist destination but the best way to see it is from the inside mendenhall glacier is a 12 mile long glacier in the Mendenhall Valley in Alaska's Tongass National Forest the ice caves are the glaciers surreal interior access to see these icy walls are only available to the truly adventurous to see the ice caves requires a kayak trip and ice climb over the glacier and once you're inside the faith that the melting walls around you won't give away but this natural wonder is under threat the glacier has been are treating incredibly quickly in recent years due to warmer temperatures and rising sea levels it has receded by almost 2 miles since 1958 but what remains is an utterly breathtaking Fantasyland [Music] [Music] think of being in a freezer and then somebody puts your face directly into a big pile of wet ice cubes that's what it feels like I'm speaking to Lisa Kelly she's a scuba diver with National Geographic and she leads expeditions in Antarctica and the arctic temperatures and Arctic waters typically range between 25 and 35 degrees Fahrenheit because the waters are so cold divers have to use special gear this includes use of a dry suit these suits actually keep divers dry when they're underwater I like to call it a self-induced state of hypothermia really because even though you're dry you're still going to get cold and that is such a shock on people's system unfortunately there have been deaths due to cardiac incident because of that aside from the cold there are other things that divers need to be on the lookout for walrus polar bears animals like killer whales reverberate sound we call it singing it sounds like a gunshot underwater it can go right through you but Lisa Kelly says that diving in the Antarctic and the Arctic is an unparalleled experience and it starts on the boat that initial feeling when you fall back in the water it's just the sound of you breathing through your regulator it suddenly becomes your own little world all of a sudden all these amazing colors start to pop out and it really is a whole other universe and in Antarctica you're there in a place where possibly nobody has ever died before [Music] [Music] these organisms are beautiful and iconic there are certain types that are present nowhere else on earth so it's very important to study them my name is drew Laura and I'm the principal investigator on science under the ice science under the ice is what we've been calling our project where we've been studying the resilience of organisms the seafloor organisms to climate related changes and we do science under the ice literally by scuba diving under frozen ocean in Antarctica the most recent trip was to explorers Cove new harbour which is in the rough sea Antarctica our team was science scientists and technicians and of those seven of them were scientific divers that dived underneath the ice we are about to commence our dive operations for the morning slash afternoon on this trip we went diving underneath the ice to deploy large-scale experiment involving incubation chambers that we deploy to the seafloor we also surveyed the fauna using standard survey techniques and we collect the organisms for isotopic analysis so we can reconstruct the food webs and how they've changed since our previous trips the water is negative two degrees Celsius it's very very cold and we have to dive through ten feet of sea ice in order to access our study sites thumbing in under the ice is quite surreal it's like diving into I light because the light is dim it's almost in some ways like diving in outer space because of the vistas that you get towards the underside of the ice with a light coming through and the clarity of the water is unbelievable it's almost like you're floating in air I think documenting what is down there now and how it's changing over time is really important this year all of us were struck by just how quickly things can change and it shows just how there is essentially climate models that are predicting changes in sea ice conditions / under the ice is pretty extreme it's hard to keep the heat up at the hunt because the the Sigma stoves are not working that well that being said the divers under the ice because of the beauty and the unique experience that it provides [Music] [Music] once you start climbing then the biggest hazard is avoiding all those big icicles they're huge like the size of a family car those daggers are really not attached that well to the rock and sometimes it takes just a small kick and they just collapse and fall down my name is clément primero I'm an ice climber and adventurer my climbing has taken me to so many different places all over the world then how come Falls came into the radar and it just changed everything I mean it's the steepest ice you can find anywhere once you're there and you're walking towards the ice phone you just get this feeling how big it is I mean it's huge and it's steep to have overhanging eyes it's really rare usually ice climbs are formed vertically we didn't see overhanging eyes before hunting Falls I do believe life starts when you step out of the comfort zone climbing forces you to go outside of your comfort zone it forces you to look out for this fragile line between having good time and not risking too much ferrets present a lot but once I'm there and once I start to work on the root the fur just goes away there's no more fear it's just about learning and having good time
