AIMS has developed a mobile app to help gather information about coral bleaching across northern Australia. Once the waves come back and pick up the trash again, you never know where it might end up. The scientist in me wants to explain how bleaching works. Earlier this year, Australia's Great Barrier Reef suffered a mass bleaching event - the third in just five years. Simply record the amount of bleaching observed and add additional information. 1996 and Rosenberg & Loya 1999), and was also suggested by Norton et al. They then exposed the cultured microalgae to increasingly warmer temperatures over a period of four years. Rising … When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. lead author Dr Patrick Buerger, of Csiro, Australia's national science agency, said in a statement, Earlier this year, Australia's Great Barrier Reef suffered a mass bleaching event.

The coral polyps benefit from the photosynthate (product of photosynthesis) and in turn, the algae benefit from the nitrogen, phosphorous, and carbon dioxide waste produced, which it needs to grow. Warmer water temperatures can result in coral bleaching. Research has shown that one thermally tolerant symbiotic alga, while reducing bleaching mortality by 30 percent, also reduces coral growth rates by more than 50 percent. This algae provides the corals with an easy food supply thanks to photosynthesis, which gives the corals energy, allowing them to grow and reproduce. Trees help to reduce carbon dioxide at the local levels. ... Key objectives of the plan are to Improve ability to predict bleaching risk, provide early warnings of major coral bleaching events , measure the spatial extent of bleaching , assess the ecological impacts of bleaching… And, as if that’s not a long enough list, the bleaching of some corals can be disease-related, too (Kushmaro et al.
