Ocean Girl

Neri is a young girl with an affinity for water, super-human strength, the ability to swim long distances, and super-human lung capacity. She lives alone on an otherwise deserted island. Early in the first season, she befriends two Australian boys named Jason and Brett Bates. This friendship is a highly guarded secret at first due to her fear of other humans. Jason and Brett live in an elaborate underwater research and environmental protection facility called ORCA (the Oceanic Research Center of Australia), located near Port Douglas, Queensland. At the beginning of the series, their mother, Diane, has been assigned to ORCA to study whale song in the hopes of facilitating cross-species communication. A significant portion of the series takes place on ORCA itself, and looks at the activities of its inhabitants, which includes the children of the resident scientists, such as Jason and Brett.
