The Humpback Whales of Cape Verde

For 12 years marine biologist Dr Simon Berrow has led expeditions from Ireland to Cape Verde. His quest? To prove humpback whales seen feeding off Ireland in summer and autumn are the same ones found breeding in Cape Verde in spring.

In 2014 his quest takes a twist. Humpback whales are showing up in Cape Verde at the ‘wrong time’ in September.

The theory? They are visitors from the southern hemisphere. Find the evidence and he will be first to document a common ground for northern hemisphere and southern hemisphere humpback whales in the Eastern Atlantic. But first he must find them.
