I posted this same question on gearslutz, but I'm sure I'll find plenty of useful insights here too.
So in a few months, I'm going to be traveling by motorcycle from New York to Ushaia, Argentina (southernmost city in the world). I'm then going to journey by ship to Antarctica. The trip will take me roughly a year give or take a few months (I won't be able to go to Antarctica during their winter months, so I need to time it accordingly).
This is first and foremost a cultural adventure. My main focus is on interacting with people and exploring parts of the world I've never been to. That being said, I would never forgive myself if I did a trip like this and didn't bring at least some recording gear. Thing is, I'm going to be severely limited in terms of space. I'm mostly interested in recording ambiences, so stereo is a must. My question for you all is, if you had the equivalent of, let's say, half of a small backpack, what would you bring (minus tripod, that can be strapped down on the bike)? Keep in mind I'll be recording in literally every climate and terrain there is, so durability is a must as far as humidity and temperatures go.
I have an SD 702 which could work as a recorder, though it's a bit bigger than I'd like. I also have a pair of CM3s set up semi-permanently in a Rode blimp in an ORTF setup, though I think that may be too big. Perhaps switch out the blimp for two baby ball gags?
One thing I'm thinking is, regardless of what light duty recording rig I use for the bulk of the trip, I can have my parents ship the rest of my gear to Ushaia so that at least for the time that I'm in Antarctica, I'll have a full rig (cause let's be honest, how often do you get to record in Antarctica?)
Look forward to the responses, thanks :)
