To celebrate International Women's Day, Morgan Pumpa made a return to the show after three years away.  She and Heather celebrated women in the marine conservation field who are achieving incredible things, from Valerie Taylor and Sylvia Earle, through to Molly Steer, Madison Stewart and Danielle Ryan.  They also looked back at women in their lives who inspired them to get involved in the ocean and develop a life long love of the sea.
