Read MoreThe Maverick Design Choices That May Have Doomed Titan
Submersibles must withstand the deep ocean’s crushing pressures, which squeeze with equal force from all sides. At Titanic’s depth – two and a half miles down – every square inch of a submersible experiences three tons of pressure. A spherical hull distributes the stress evenly, making it the best shape for resisting the compressive forces…

Scientists used the submersible, Alvin, to make amazing discoveries, including these ancient deep-sea coral reefs recently discovered within the Galápagos Marine Reserve.
Read MoreWhat is the future of submersibles after Titan implosion?
The Titanic submersible’s deadly implosion raised serious questions about the safety and future of vehicles that are sometimes unregulated. NBC News’ Kristen Dahlgren visited the Woods Hole Oceanographic Institution to learn how its vessels are tested and designed.

Read MoreKama’ehuakanaloa Seamount Hydrothermal Vent Expedition: Expanding Early Career Involvement
Early career researchers from various institutions set sail aboard the Kilo Moana Research Vessel today to visit Kama’ehuakanaloa Seamount (formerly known as Lō’ihi), the youngest volcano in the Hawaiian-Emperor Seamount Chain. This NSF-funded collaborative research expedition, led by WHOI Senior Scientists Chris German and Jeff Seewald, is investigating the impact on the subseafloor hydrothermal circulation…
