There is only one submersible in the world that on any given day can dive, taking its pilot and one other person, to the deepest parts of the ocean. To reach the bottom of the Challenger Deep, Caladan Oceanic’s Deep Submergence Vehicle (DSV) Limiting Factor, descends through the water column for four hours. By the tenth minute of the 11 … Read More about How deep is the ocean? Mapping, measuring, and diving to the Mariana Trench’s Challenger Deep
Investigating seafloor crustal deformation with RBR loggers
Professor Ryota Hino of Tohoku University uses RBRsolo T|deep|slow and RBRduet T.D|deep loggers attached to a submarine acoustic ranging device to investigate seafloor crustal deformation. The submarine acoustic rangefinder accurately measures the distance between two points by sending a call signal from another device installed on the seabed at a remote location and measuring the time until the response signal … Read More about Investigating seafloor crustal deformation with RBR loggers
