Humpback Whale Migration

The Arctic University of Norway leads the Whaletrack program to map Humpback and Killer Whale migrations. 

Whales are tracked as they travel thousands of miles from the Barents Sea in the Arctic where they feed to winter breeding breeding grounds in the Caribbean Sea. The map above (posted on Flickr) beautifully illustrates the paths of various tracked whales. I like how the (unspecified) map projection shows a more or less direct great circle-like route across the Atlantic to the coast of Norway and then to the Svalbard Archipelago. 

There is also an interactive map where you can choose individual whale tracks and see dates.
