Human-Occupied Submersible Makes Historical Dive By Reaching a Depth of 21,325 Feet

On Thursday (July 21st), the human-occupied submersible Alvin made background when it effectively got to a whopping deepness of 21,325 feet (6,453 metres), achieving the inmost dive ever in the 58-year history of the storied submersible, in proportion to a press release by the Woods Hole Oceanographic Institution (WHOI). The event occurred in the Puerto Rico Trench, north of San Juan, P.R.

A critical step to United States Navy certification

The dive was a vital step to accomplishing certification from the united state Navy to return to operations after an 18-month break undertaken to upgrade and upgrade the sub’s maximum power dive range from 14,800 feet (4,500 metres) to its brand-new limit of 21,325 feet (6,500 meters). This procedure was conducted since Naval Sea Systems Command (NAVSEA) requirements stipulate the certification dive be between 6,200 and 6,500 metres.

“Investments in unique devices like Alvin accelerate scientific discovery at the frontier of knowledge”, stated WHOI President and Director Peter de Menocal. “Alvin’s brand-new ability to dive deeper than ever will help us learn even more about the planet and bring us a greater appreciation for what the ocean provides for all of us daily”.

Alvin is one of the only deep submergence vessels in the world capable of carrying people into such deep depths and conducting scientific research of the ocean seafloor. The sub has completed 5,086 successful dives on Thursday’s dive method, more than all other submersible programs in the world combined.

On average, the vessel undertakes about 100 dives annually on missions to analyze the processes that shape Earth’s crust, the conditions that make it possible for life in an excessive atmosphere, and the great diversity of life in the deep sea.

“For nearly 60 years, the deep-submergence vehicle Alvin has unveiled the ocean’s mysteries– not just for the military and national security purposes but also for the scientific benefit of society as a whole”, said Principal of Naval Research Back Adm. Lorin C. Selby.

NAVSEA tests

For the past 3 weeks, Alvin further underwent a series of examinations as part of its sea trials, overseen by the NAVSEA, that designs, builds, and maintains united state Navy ships and submarines. These consisted of tests of its mechanical and electric systems and its capability to operate safely at depth. The end outcome of these tests was consent to resume its operations and to dive to its new record-breaking maximum depth.

“Being able to function with the Woods Hole and ONR group to certify Alvin has been an honor for us”, stated NAVSEA’s Commander, Vice Adm. Bill Galinis. “At NAVSEA, we like to state we expand the Navy’s warfighting advantage; however, with Alvin, we are now broadening researchers’ capacity to learn more regarding internal area thanks to our world-class engineers and deep submergence know-how”.
