Terry Kerby has been described as the most experienced submariner on the planet.
He has been piloting submersible vehicles since the mid-1970s, allowing him to get up close to some of the ocean's deepest trenches and the most remarkable undersea landscapes.


Terry Kirby's image of the Pisces V submersible in the Hawaiian abyss. He recreated the scenes as illustrations as they are so difficult to photograph because of the limitations of light and space.

He is the director of the Hawaii Undersea Research Laboratory, known as HURL. Much of his work has been done in the waters around Hawaii, in his submarine, Pisces V, which he has also piloted in a survey of the volcanoes in the Kermadec arc, northeast of New Zealand.
The scenes he get to witness are so remarkable, he has created his own illustrations of the undersea pinnacles and volcanic vents - because, he says, the limitations of light and space make them impossible to properly photograph.
He talks to Kathryn Ryan about his undersea career.
Terry Kerby will be speaking at the upcoming Kermadec Science Symposium in Wellington next week (April 11)
