Sonar Research on MY Esperanza in the Amazon Reef

Deep divers have successfully completed the first human dives ever made on the recently discovered Amazon Reef, off the coast of French Guiana.
The objective of these first dives performed by six professional and qualified deep divers aboard the Greenpeace ship Esperanza, is to document and collect biological samples in order to better understand this reef system and reinforce its need for its protection.
The Amazon Reef is an underwater treasure and an unique ecosystem already threatened by giant oil companies that intend to drill nearby.
