It is the deepest trench in the world’s deepest ocean, and now scientists have a new map of it. Using sound waves, scientists have pierced the lightless depths of the western Pacific Ocean and drawn a new picture of the Mariana Trench. The maps above were made from data collected and analyzed by researchers at the Center for Coastal and Ocean Mapping/Joint Hydrographic Center at the University of New Hampshire (UNH). Depths are reflected by shades of blue, with the deepest reaches represented by the darkest blues. The black outline shows the outer edges of the nearly 400,000 square kilometers of seafloor surveyed by the oceanographers. The researchers used multi-beam echo sounders to map the Mariana Trench from August to October 2010. Mounted on the hulls of ships, the instruments send pulsed sound waves toward the seafloor and then record the echo-like reflections. Multi-...
