Descending (2012)

S1E4 The Emerald Sea

In British Columbia, Canada, Scott returns with Ellis and the Descending team for an exhilarating cold-water diving adventure around Vancouver Island. While exploring the depths, Scott and Ellis encounter some unusual marine life and even take the controls of a jet submerged 80 feet down. On the surface, the team rolls up their sleeves to get a ship ready for its planned sinking.
