June 20, 2015


 
            Today we mostly traveled and listened to presentations about polar bears and arctic travel.  The pack ice outside ranges in size from the size of an icecube to the size of a city bus.  The ocean slowly rolls below us, raising the ice together in gentle waves.  From time to time the whole ship shakes, booming like a gigantic drum as we strike a particularly large chunk of ice.

A blue whale.

            Whales!  First we spot multiple great blue whales, the largest animal that has ever lived.  They were once driven extinct in this area because of whaling, so it is amazing to see them here.  They surface around us, blowing out air before diving again.  We can only see a small fraction of their bodies at a time, but even that amount is huge.
            Next we see fin whales (second largest animal on the planet) followed closely by a humpback.  The humpback is being trailed by a flock of kittiwakes -- we can tell where the whale will surface by watching the birds.  They lie quietly on the ocean surface watching, then altogether they take off, swarming in the same direction, coming down again on a patch of ocean just as the whales bumpy head breaks out of the water.  Small compared to the other two species, it's amazing to see his/her tail fly out as s/he dives again.
