Article Summary:

International Supermodel (and Wetpixel member) Giles Shaxted has started a discussion about water temperature increases in the ocean and the effects it may be having on wildlife, as observed by us (common divers):

Here in the Cayman Islands we blame [water temperature increases] for out algae bloom every year. Some years it is worse than others, but for the most part people know that our North Sound (where Stingray City is) is shallow enough to show large temp increases from the sun, and the powerplant is right there as well which if using salt water to cool things down would be letting hotter water into the sound. When the sound is warm enough the algae blooms and the water becomes green, then the tidal movements will push the green water out to deeper areas where the algae can then settlle on the reef and smother it…
