Now an Education Ambassador, Tim Barker spent four expeditions aboard the M/V Ocearch alongside 
a diverse international team of scientists in the pursuit of studying North Atlantic Great White Sharks. 
While traveling the eastern seaboard and visiting varying ocean habitats Tim assisted with a continuing 
study of 20 sharks ranging from juveniles of five feet in length to adults stretching beyond fifteen feet. 
As an organization Ocearch has tagged 92 White Sharks in the North Atlantic and provides data for 
over 400 animals around the world.
