... a constant 32 degrees Celsius, the corals bleach. Corals are only capable of living in a very narrow temperature range, between 25 and 29 degrees Celsius, hence the rise in water temperatures in the areas that the coral have been growing (some as long as 2.5 million years (Guilcher 1988) are beginning to bleach the corals. New evidence suggests that over time the bleached corals can regain their color and have a potential ... for regrowth, however if the bleaching occurs too ... ...

... need to be sure that we are using remote sensing to promote wise costal practices in so far as coral reefs. Coral reef color essentially refers to digital remote sensing of coral reefs. The most common application of remote sensing in coral reef environments is geomorphological mapping. This is because, historically sensor capabilities have been sufficient to identify only broad ... are able to provide information on reef geomorphology and limited ecological information such as the location of corals, sand, algal and seagrass habitats with an accuracy ranging from 50-70%. The most cost ef...

... the loss of intracellular endosymbionts through either expulsion or loss of algal pigmentation. Zooxanthella is what gives coral reefs their apparent color. When bleaching takes place, the zooxanthellae is expelled by the reef, which makes the reef look white, like it has been bleached. Bleaching occurs when the coral reef feels as if it "under stress", the most common "stress" a coral can face is the rising of the water ... temperature although, there are a number of biotic and abiotic ... factors which can inflict "stress" upon the corals. Stress can occur when the oceans temperature ...
