While some people are #ockham listed best i can manage is #TheConversation. Strange to write an article on an #Antarctic expedition that was a decade ago - but we only managed to retrieve the full data set 3 years ago when a later expedition managed to get to the instruments and we discovered more data had been collected after the satellite link had broken.

@wavygk Fascinating stuff.
Is the 420m depth measured from the top of the ice, sea level, or the bottom of the ice?
Does the bore stay straight, or are there shifting layers that woul shear your cables? Presumably it freezes over regardless - but maybe not if you leave a cover over it?
Is it feasible to access that region horizontally, with some kind of submersible or thick wetsuit?
@richardh thats the liquid water column height so from the underside of the ice shelf. It definitely refreezes thats our main game - getting gear in and out without having it trapped as the hole refreezes - we havn’t always won. Definitely not diveable but groups are starting to use autonomous underwater vehicles. And thats one of the newer projects we are collaborating overseas (beyond NZ budgets). This location was over 300km from open ocean.
@richardh whilst stuck waiting for a flight on a later expedition we made this Doctor Who video mashup of the view dropping down the hole… https://vimeo.com/353734045
