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.

The ship departed New Orleans at 0830 hours to head down the Mississippi River. A convoy of freighters passes Atlantis's starboard
side, going upriver. (Photo by Chris Linder, Woods Hole Oceanographic Institution)
The voyage down the muddy Mississippi took nine hours passing industrial areas in the delta region. (Photo by Chris Linder, Woods Hole Oceanographic Institution)
Atlantis reached the Gulf of Mexico and the open ocean as the moon rose over the Gulf--a delightful setting for WHOI scientist Adam Soule to do a little strumming on his ukulele. (Photo by Chris Linder, Woods Hole Oceanographic Institution)
Moonlight bathed the surface of the Gulf of Mexico, though most people on board were too busy preparing for today's Alvin dive to notice. (Photo by Chris Linder, Woods Hole Oceanographic Institution)

Nearly 900 days since its last research dive—and the most extensive upgrade in its nearly 50-year history—the submersible Alvin is scheduled to return to the depths this morning on a science mission. Everyone on board the R/V Atlantis, from scientists to pilots to ship’s crew, is abuzz and eager to launch the new, improved sub. Read More →
