      > We align the station every week to ensure that it is always on level ground. Every now and then, one of the bipods wanders off – then it’s time to lift and realign.

    2. This is one of the coolest buildings I’ve ever seen, if it is indeed considered a building, I’d argue in court it’s a gondola. At any rate I like it.

      To be exact, it’s Neumayer Station III.

      The first two consisted of steel tubes, and while that meant they could withstand the pressure of the ice and snow and remain operational for a while even after they had sunk underground, eventually they got so deep they had to be given up.

      Interestingly, the first one has actually risen back up a bit, and 6½ years ago the scientists from Neumayer Station III found the exit of its staircase tower above the ice, but the structure was too damaged to safely go all the way down into the tubes again.

    4. fascinating! but i have to say that since you are doing this regularly, it looks like you need a more efficient way to remove the snow under the stilts and to blow new snow under it. it seems to be the most tiring part of the process.

      So this building sits on 16 leg assemblies, each of which is actually comprised of 3 loaded members that make a single contact point with the ground, and they went with bipod?

    6. One of my favorite things about the arctic is that people struggled for decades to build custom purpose built vehicles and modified tractors, and dealt with life threatening challenges, only for modern times to just send a Toyota Hilux and call it good

    7. I was lucky enough to have been at Neumayer 3. unfortunately we only had about 30 minutes before we had to go back so there was no time to visit the garage! Inside is cool as well. And one of the craziest places I’ve been!

    8. I know the guy who engineered the system. The measurement system of the inclination is quite funny. As inclination sensors would not be accurate enough, they put water tubes accross the whole station and measure the height of the water at each end of the station and determine the inclination based on this.

    9. OK, but why is it called a bipod if there are sixteen of them or if there are three hydraulic jacks holding it in place, not two?
