Undersea New Zealand, a high resolution image of the complex and diverse marine realm around New Zealand.
Undersea New Zealand provides a unique insight into the shape of the seafloor within one of the world's most extensive deepwater jurisdictions. New Zealand straddles an active plate margin, creating a highly complex and diverse seascape of submarine trenches, underwater volcanoes, active submarine canyons and quiescent broad plateaux.
