If you’re going where there’s no air to breathe, you better be organized. Any kind of underwater diving involves process for that very reason. There’s the early-morning wake-up, the weather check, the gear check (masks, fins, regulators … check). And then there’s the dive site approach – whether you’re walking in from the shore or taking a boat to some far forgotten reef. Diving Lake Untersee is just like that – except in Antarctica we get to our dive site by snowmobile. And Untersee ratchets up the workload because it’s remote, technical and cold.
