The rest of her time is much like ours, just sitting at a desk tapping away at a keyboard or mouse. But 1.5-2 months of her year are booked by her employer to be off surveying. They see whales, go fishing and dive for food in their spare time, visit remote waters in the arctic or BC coast, stay in interesting communities along the coast, and all kinds of neat stuff.
Of course it isn't perfect and the ~10 months spent charting is so tedious that it gives me mild discomfort from a distance. I think the value of having quality navigation charts for the ocean is a little known but incredibly important asset to any place in the world though. Vessels travelling safely is the backbone of trade, tourism, fishing, and many kinds of recreation. I suspect there's some satisfaction in that at least.
My friend is a marine biologist and she dives off tropical islands in beautiful blue ocean water. The other day she talked about how everyone said it must be amazing to live this life so close to nature and she said it's really fucking hard not to flip out. The job is hard and painful and to be honest, my job as a software engineer is way better because I get to have fun wherever I want two days a week.
It's not that I think people can't be happy at a desk. I've been very happy. Just looking for a change and some sunshine.
