 The team used technologies such as acoustic sampling to locate potential reef sites, and confirmed the discovery by dredging the floor of the reef, bringing up samples of corals, sponges and other reef species onto the ship deck.Their discoveries and findings were detailed and presented in a research article published in the scientific journal "Science Advances" in April 2016.Some of the waters in the Amazon Reef are considered to be some of the murkiest and muddiest waters around the world due to the Amazonian plume.
