Dave Owen developed an interest in deep-sea photography — then a field in its infancy — early in his career at WHOI. During a cruise to the Mediterranean and Aegean seas aboard R/V Atlantis in 1947, he was assigned a Ewing deep-sea camera to take flash photos of the sea floor. Dave captured the "deepest" photograph of the sea floor (18,000 feet) at the time — a record that stood for years. The photo was later published in Life magazine.
