On Thursday, scientists on the Alvin Verification Cruise adjusted high-intensity LED lights on the sub’s “brow” and just above the forward viewports (not seen in this drawing) to perfect the lighting so they can obtain sharp, shadow- and glare-free photos and videos from the sub.

The whole objective of this research cruise is to test a newly rebuilt Alvin equipped with upgraded systems that had never been used before by scientists under field conditions. Scientists and engineers expected hiccups and learning curves. After four test dives of Alvin, it was time to tweak, troubleshoot, and optimize. Read More →

WHOI marine geochemist Susan Humphris narrates scenes from Dive 4679, the first science mission after Alvin‘s recent comprehensive overhaul, highlighting the sub’s new imaging systems. HD cameras (including two pan-and-tilt units) and high-intensity LED lights promise to make stills and videos captured by scientists of the deep sea even more useful and spectacular.

Alvin, the nation’s only deep-sea research submarine, took its first scientific dive yesterday [March 15] after a 39-month hiatus and a major overhaul that dramatically upgraded the sub. Read More →

On March 15, 2014, the submersible Alvin conducted its first science mission since a major upgrade began in 2011. In the personnel sphere were WHOI scientist and leader of the upgrade project Susan Humphris, who commented on the sub’s performance, and Nathan Brown, a pilot-in-training, who received the traditional dousing with ice-cold water for first-time Alvin divers.
