Today’s Image of the Day from NASA Earth Observatory features Broad Sound, a large bay located in Queensland on the eastern coast of Australia.

Along the world’s coastline, tides usually fluctuate by no more than two meters. But in Broad Sound, located near the southern end of the Great Barrier Reef, the daily high tide may reach as high as ten meters above the average low tide.

The tides in Broad Sound are influenced by the shape of the bay and the shallow waters of the reef. 

The image, captured by the Operational Land Imager (OLI) on the Landsat 8 satellite, shows the bay area around 10 a.m. on October 29, 2020, as the high tide crested under the gravitational pull of the Moon. 

Norman Kuring of NASA’s Ocean Biology group used color-filtering techniques to highlight the remarkable details of swirling sediment and phytoplankton.

According to NASA, the bay contains 48 islands, which are all part of Broad Sound Islands National Park.
