Hostile work enviornment
Yeah, without very careful route planning and possibly additional bedding, this may be tough to keep running. Re-patching breaks in a crossing of the entirety of the Furious Fifties and Shrieking Sixties, the idea gives me the willies.
Not that is can't our shouldn't be done, just that it's a pretty brutal environment. Still, once it's laid in it would provide a critical service for ongoing science in Antarctica. Since we are looking at parking some new science instruments down in the cold, it would reduce the turn around time considerably if the winter data didn't have to get flown out on the first flight after the sun came back up.
May also save lives if they need to perform advanced telemedicine or deal with other failures. I have seen the postings for the over winter sysadmin job there. Never thought I was a good enough hand with a soldering iron to be the guy to McGuyver a failing Satcom system in the howling dark. I feel like whoever that person is they deserve a backup connection and a shot at a (number of hours equivalent to a middle latitude) nights sleep.
