Antarctica, Polar Research Area.
Here and the work environment of the Pacific Division aren't much different, one deep under the sea, the other beneath the permafrost, everyone hunkers down in the base all year round without going out, but the working atmosphere at the two places is quite different.
In the Pacific Division, most of the contained objects are extremely dangerous, so despite the constraints of water pressure, there can't be any slack, for two reasons: first, the cost of remediation after a containment breach is too high, and second, by the time the containment is retrieved from the deep sea... the things inside have already died.
