Britain's Secret Seas: Season 1, Episode 2

1 - 2: The Wild North

In the second programme in the series, explorer Paul Rose, marine biologist Tooni Mahto and maritime journalist Frank Pope explore the wild seas around Scotland.

The team travel to Bass Rock, one of the largest gannet colonies in the world. They are there to try and find out why, when most British seabird populations are in decline, the northern gannet is bucking the trend. Tooni helps scientists who are using GPS trackers to discover the extraordinary distances gannets can fly in the search for food. Paul goes beneath the waves to witness the amazing diving ability of Britain's largest seabird.
