After a decade of planning, designing, engineering, and construction, an upgraded Alvin has been delivered to the nation’s scientific community.
“So then what? What do you do? Brand-new submarine, fresh off the lot,” said Peter Girguis, chair of the Deep Submergence Science Committee (DESSC), a group of scientists that advises on the best use and operations of the sub. Read More →
