1 day agoExplorers find a secret ISLAND in Antarctica's 'danger zone'
A previously undiscovered island was found in the Weddell Sea by scientists seeking shelter from rough weather.
One of the most indispensable items for spring tent camping is a rain fly. Your tent probably comes with one, but when that thing gets absolutely drenched, the water will soak through and drip from the ceiling. So, install this tarp above your tent and at an angle, so the rain rolls right off it.
The RECCO system is a search-and-rescue technology designed to help professionals locate people buried in avalanches or lost in the outdoors. Today, it is integrated into millions of pieces of ski and outdoor equipment worldwide.
Imagine waking up on a ship surrounded by icebergs, camping in the snowy wilderness and kayaking among the exhalations of humpback whales. You can also take part in a polar plunge, board small zodiac boats to search for leopard seals and collect samples for science research.
Travelling there was a childhood dream of mine. I saw it as a way to test myself against something so much bigger. I nearly applied for a role at the British Antarctic Survey (BAS) 30 years ago, but then my wife and I were expecting our first child. Instead, I've worked as a chef in Michelin-star restaurants in Paris and London, hotels in Kuala Lumpur and St Moritz, and even at a school in Oxfordshire.
I don't know who invented this crazy challenge, but the idea is to put someone in a carved-out ice bowl and see if they can get out. Check it out! The bowl is shaped like the inside of a sphere, so the higher up the sides you go, the steeper it gets. If you think an icy sidewalk is slippery, try going uphill on an icy sidewalk. What do you do when faced with a problem like this? You build a physics model, of course.
The Winter storm has no name. But a storm is coming, An extreme winter weather system is expected to move eastward from New Mexico to Georgia and Maine beginning Friday, and affect anywhere from a third to half the country's population by the end of the weekend. This will likely bring snow, ice accumulation, and biting cold to parts of the country unaccustomed to harsh winter weather.
So, believe it or not, the cold air that we get down here actually tends to help the performance of the helicopter. DAN: The low pressure systems we have here, particularly in this, weather we've been having, tends to create the opposite effect by decreasing the pressure. Low pressure systems, thinner air. DAN: And that cooler air makes the pressure higher again.
Decades of successful scientific collaboration could be at risk if Europe-US political relations continue to fray over trade and defense issues. For more than 30 years, Arctic nations have worked together across the physical, biological and social sciences to understand one of the world's fastest changing regions. Since the late 1970s, the Arctic has lost around 33,000 square miles of sea ice each year roughly the same area as Czechia.
I'd been stopped maybe 2 seconds and the slope started to move. I pivoted to straightline but was swamped-no speed, no chance. The impact was like stepping off a curb in front of a 40 Tonne truck doing 60 mph.
The sport is unique in that it asks for prolonged endurance on the uphill, then explosive strength and stability on the way down. Most gym routines do not train both. This one does. The five exercises Bell recommends are the single leg Romanian deadlift, the standard and multiplanar step up, the renegade row, the deep split squat, and the single leg hip flexor raise with band resistance.
When you're touring in the backcountry, you'll want a different kit than what you wear inbounds at the resort. Inbounds, your main goal is to stay warm and comfortable, and you're usually not working nearly as hard as you do on the skin track. Touring generates a lot more heat, so your layering system has to breathe, manage moisture, and still keep you warm when you stop.
In ice climbing, you want to try to have a solid base with your footing and to get the ice axes over the tops of each other to have the most leverage. We worked on these skills from the comfort of top roping, which entails having a fixed anchor you can rappel down from. This gives the feeling like you are in a climbing gym and greatly reduces the risks.
Cornice collapses can be incredibly dangerous, having the potential to crush people, pull them down mountains and potentially over rocky cliffs, and cause larger avalanches. Professional skier Josh Daiek doesn't seem to be impacted by cornices as much as a regular skier or snowboarder would be, though. This incredible line starts with a heart pounding moment as he looked over the edge.
Recently, Anchorage, Alaska's largest city with nearly 400,000 residents, has just recorded its snowiest January on record. Tucked in between the mighty Cook Inlet and pushed right up against the Chugach Mountains, Anchorage sits in prime location for some serious snow totals. Moisture from pacific storms builds up over the inlet, and thanks to orographic lift caused by the mountains, forces that moisture to drop over Anchorage. Thanks to Alaska's northernly location, that moisture often falls in the form of snow.
