    "The crew of an icebreaker
    is watching a large 'hummock' off
    the starboard bow. What are they
    looking at?"

    I believe a hummock is a mound of ice. I'm just guessing here but I think they can be pretty large and are caused by pressure in the ice field maybe? Like a ridge or something? I got the impression after doing some reading that they are not something even an icebreaker would want to encounter so I assume that's why they keep a lookout for them.

    Yes, a hummock is a pressure ridge of pack ice pushed together. And are just as deep as they are tall.
    I was on the Polar Star in "82 for a pressure ridge test. It was frigging awesome!!! We hit every big ridge we saw, as hard as we could. I was a BMOW, but when BMC Burnaw, or "HAMMERIN" Hank Haynes, had the Conn, I took the helm, and they let me twist and turn anyway I wanted...
