As a follow-up to my previous post on polar bears giving birth (December is polar bear nativity month) I thought I’d continue the generalized theme of “polar bears in winter.”
While we don’t really know for sure what non-pregnant polar bears do during the depth of the Arctic winter, we have bits of evidence – some from modern hunters and polar bear researchers but also from Arctic explorers. One explorer in particular comes to mind: William Barents [Willem Barentsz] of Holland, who attempted to reach China via the Arctic Northeast Passage in the late 16th century. On their third voyage (1596-1597), Barents and his crew were forced to spend the winter on the northern tip of Novaya Zemlya (latitude 760N, see Fig. 1) when their ship became trapped in the sea ice. Crew member Gerrit De Veer (1609) kept a journal account of the long, horrifying winter they spent on shore, in a shelter they built with materials salvaged from the ship. They called their winter home Behouden Huys (“the saved house”).
Figure 1. Location of Novaya Zemlya, in the Barents Sea. On the map at left (a), the black square marks the location of Behouden Huys, the over-winter home of William Barents and his crew (1596-97) on Novaya Zemlya (the “track of boats” noted marks the return journey of Barents in the summer of 1597). This is modified from Zeeberg et al. (2002:331). The map on the right is from Wikipedia, for perspective. click to enlarge.
An English translation of De Veer’s journal is now available online and it offers a fascinating glimpse of what it meant to live through that long dark winter under almost-constant fear of attack by polar bears. The Dutchmen were plagued by polar bears almost the entire time they were on Novaya Zemlya (see Fig. 2). De Veer’s notes on these encounters provide a unique perspective on polar bear activities over the Arctic winter – ironically, it is not the havoc the bears caused that provides the most important clue but rather, the timing of when they left Barents and his crew alone.
Figure 2. An engraving from De Veer’s journal conveys the struggle the crew faced in warding off polar bears during their winter stay at Novaya Zemlya. The bears not only stalked and attacked the crew, they got into the food stores on the ship.
