An underwater Seamount (Mountain) that is 1.5 times the size of the Eiffel Tower was discovered within the boundaries of the Great Barrier Reef Marine Park. The Seamount is teeming with life in the form of vast coral reef systems that sustain a diverse population of underwater life such as gorgonians, cuttlefish, and large sharks to name a few. The discovery boosts the diversity and health of the Great Barrier Marine Park that has had a tough time over the past few years. Climate change has caused sea surface temperatures to rise in the area to a point where 93% of the corals bleached a few years ago. The increase in the number of days where the air temperature was above 40C helped increase the water temperature, which causes the corals to bleach. Corals have phytoplankton called zooxanthellae that live inside the coral skeleton and undergo photosynthesis to survive while their byproducts (O2 and Ca+ ions) help build the corals calcium skeleton. The zooxanthellae can only handle a certain amount of heat and w
