In November 2021 Dr. Chris Harvey-Clark was diving with a colleague at the mouth of Halifax harbour when they encountered a 3-meter Great White shark. The shark made a number of passes before the two divers were able to reach the surface and board their dive boat. Chris is a regular diver and marine ecosystem expert with Dalhousie University, but the encounter still caught him by surprise. Chris shares details of the encounter and what the return of white sharks to Atlantic Canada may mean for the ecosystem, tourism, fish and fishing, on The Blue fish Radio Show.
