Oceanus Magazine: Who is Alvin and what are Sea Trials?

Alvin is at sea doing test dives to increase its depth rating from 4,500 meters to 6,500 meters (~15,000 feet to ~21,000 feet). This depth will put 99% of the ocean floor within reach for the U.S. deep sea science community. If you haven’t been following Alvin’s journey to 6,500 meters, Oceanus Magazine will catch you up here.
