Field production for Under The Sea 3D consisted of five major month-long expeditions to five different locations. The first two expeditions were to New Britain and Milne Bay in Papua New Guinea aboard the diving live-aboard, Star Dancer. For the third expedition we moved south to the cold waters of South Australia with Rodney Fox Shark Diving Expeditions aboard the Princess II. After South Australia we filmed on the Great Barrier Reef aboard the Undersea Explorer. The final expedition was nearly six weeks in length aboard the Indonesian live-aboard Seven Seas.
