Scientists and oil companies were completely surprised to find a huge coral reef which is 3, 500 square miles below the muddy waters at the mouth of the River Amazon. Corals usually thrive in clear, sunlit, water so it was a huge surprise to find one in the heavy sediment of Amazon river mouth.
The reports co-author said: “I was flabbergasted, as were the rest of the 30 oceanographers. Traditionally, our understanding of reefs has focused on tropical shallow coral reefs which harbour biodiversity that rivals tropical rainforests.”
But as quickly as it was found it might disappear rather too soon as the Brazilian government has sold 80 blocks for oil exploration and drilling at the mouth of the Amazon and 20 of these are already producing oil – some, it is thought, right on top of the reef.
