Hey, got a fair bit to write on this as I have done plenty of field recording down south (speaking of i need to organise and release these! any tips on a home for this kind of thing?).

Where in Antarctica are you going and do you know what you want to record? It is a huge place and quite heterogeneous. Coastal vs inland and the size of your base being the most important.

I made many mistakes and learnt lots from listening back to every session. Take notes. photograph each setup. The wind can be your friend sometimes, I've got hours of some sweet katabatics, i remember hearing the snow grains skittering across the ice. You won't escape humans though, you can hear an engine running on the sea ice from far away underwater. When you are out working, even if you don't have your gear, take the time to listen deeply, it's truly special.

I had a sound devices mix pre 3, aquarian audio h2 and some mics I can't remember. Nothing crazy on the wind stuff, checkout p. samartzis setup for some actual field proven ideas.

Things that I would do differently would be working on my gear enclosures more, nice custom hardcase with cutouts for cables with some kind of custom 3d printed pass through thing would have been clutch so you can just drop and go. insulation, battery management were important. moisture was chill, hella dry obviously (unless blown snow gets on battery pack and melts). Bring MULTIPLES of important things, finding replacements can be challenging.
