Heron Island, Australia

Heron Island is located at the sourthern end of Australias 2,050 km-long Great Barrier Reef. Surrounded by coral reef and home to over 1000 species of fish, scuba divers and scientists alike are drawn to the islands resort and research station. The true-color image above was taken by Space Imagings Ikonos satellite with a resolution of 4 meters per pixel—high enough to see individual boats tied up at the small marina. The narrow channel leading from the marina to the ocean was blasted and dredged decades ago, before the island became a national park. Since then the Australian government has implemented conservation measures, such as limiting the number of tourists and removing or recycling, instead of incinerating, all trash. One of the applications of remote sensing data from Ikonos is environmental monitoring, including studies of coral reef health. For more information about the island, read Heron Island.

Fires on Cape York Peninsula, Australia

Grasslands and tropical savannas dominate northern Australia. These landscapes dry dramatically after the rainy season and become extremely fire prone. The most devastating fires usually occur late in the dry season, which runs from May until October. In this true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from October 10, 2002, numerous large fires on the Cape York Peninsula are marked with red dots. Dark burn scars show the extent of the fires.
