Yeah, the only thing to assume is that she froze, yes, there was a crawler there with its lights on, meaning it'll probably die soon...and she is out in the cold with no worm gear at all, as someone else pointed out, who knows just how far away the boat is, there was a decent drive in the crawlers from the boat to the whaling station, so even if she did radio for someone to come get her, I doubt they'll get there soon enough for her to be ok in such cold temperatures.
So the safest bet is she died...for one reason or another...
