Hello! Danielle here, I'm a PhD student working primarily in the Arctic marine environment. This is a fun question -- mainly I have spent time on ice breakers during field campaigns as well as a bit of time up in Svalbard. The research ships can have a very intense environment, after a couple of days it really starts to feel like you have spent weeks together with the same group of people. This is really a perfect setting for people to meet new ship-romances (whether they admit it or not that is a second thing) -- but I agree with one of the other comments from Stefan earlier, a lot of these field campaigns seem to be their own social experiments in a way! In my experience there is also a high likely hood that any flirty behaviour is noticed by the rest of the crew pretty fast, for me it always ends up feeling a little bit like you are at an adult summer camp forming some pretty deep connections while also "giggling" a bit about different developing relationships. For the second part of your question about what do to for fun -- Svalbard is a really incredible place to explore! Personally, I am pretty excited to be outdoors at home but in Svalbard it is on another level, and with the added element of having to keep polar bear safety in mind for even small hikes! :) Thanks for the question!
