Global increases in beach sand temperatures are predicted to skew hatchling sexratios of marine turtle populations towards female bias. Currently, shade structures and fresh-water irrigation are management strategies used to cool nest temperatures, but require resources that are limited at remote rookeries. Here, we report on a novel investigation that used seawater irrigation as a sand-cooling method. Various volumes of seawater were applied to sand to deter-mine the optimal application required to lower sand temperatures at nest depth to produce male-biased sex ratios.

An educational film on marine life, describing the many species of coral, the Crown of Thorns Starfish, reef fish, turtles, sea birds, sharks and whales. A very interesting and colourful presentation of these marine animals and their many existing species all contributing to the splendour and mystery of the sea.

This is a story about the Aborigines of Australia, providing us with an understanding of their traditions such as the initiation ceremony, and their fight for their traditional land now owned by the Commonwealth government. With footage taken from four Aboriginal communities, one learns of the significance of land to Aboriginal culture, and the close relationship that exists between them. These four communities are; the "Giru Dala", "Kowanyama", "Dajibuka", and "Darumbai".
