Minke Whales

Every day the water opens up a little more.
This little hole from last week is now open water with lots of whales!

Minkes are the smallest of the baleen whales, eating plankton, krill, and small fish. They have 2 blowholes, but they start blowing out air before they reach the surface, so the spray isn't as spectacular as some whales (although we saw a lot of blowing and spraying today!). Apparently they can live up to 50 years. Ha, it's possible my Dad may have seen the very same whale 46 years ago.

The whales breathe several times in a minute before gulping a huge breath, arching their backs, and going deep for as long as 20 minutes. We watched them swim underneath a quarter mile of ice pretty quickly. They can swim up to 25mph!

The whales swam way out toward the ice shelf and had to poke themselves up through tiny holes. I saw heads bob up several times.

Minke whales are pregnant for 10 months, and they weigh 882 pounds when they are born. Whew.

The water stays disturbed for some time after they dive.

Last big breaths before headed out to the channel where the Russian ice breaker is still working.
