"A polar bear carves out a bed from a small iceberg before drifting off to sleep in the far north, in Norway’s Svalbard archipelago. Having spent three days searching for polar bears through thick fog, the expedition vessel Nima was on changed course. It turned and headed to where there was still some sea ice. Here Nima encountered a younger and an older male polar bear. Just before midnight, the young male clambered onto a small iceberg and, using its strong paws, clawed away to carve out a bed before drifting off to sleep."
