Heavy rains and high winds forced the cancellation of yesterday’s dive to cold seeps and deep-water corals at Mississippi Canyon (MC) 036. (Photo by Chris Linder, Woods Hole Oceanographic Institution)
In 2010, WHOI’s autonomous underwater vehicle Sentry mapped MC036, the location of the next dive. In 2011, deep-sea corals were discovered at the site 1095 meters below the sea surface. (Image courtesy of NOAA/NRDA)
Alvin Expedition Leader Bruce Strickrott fits and tests an emergency breathing apparatus (EBA) for University of Minnesota engineer Tan Chunyang. The EBAs are used only in extreme emergencies. Normally, tanks in the personnel sphere supply oxygen and a "scrubber" removes carbon dioxide. (Photo by Chris Linder, Woods Hole Oceanographic Institution)

It may be small consolation to any folks up north who are facing yet another winter snowstorm, but the weather hasn’t been so great down here in the Gulf of Mexico either. Read More →

Scientists and engineers boarded the research vessel Atlantis in New Orleans for the expedition to test the upgraded Alvin submersible. (Photo by Chris Linder, Woods Hole Oceanographic Institution)
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 →

About

From March 14 to 26, Peter Girguis, chair of DESSC (DEep Submergence Science Committee), will lead a group of scientists, including many veteran Alvin divers, from a host of research institutions to “road-test” the new vehicle on an expedition in the Gulf of Mexico. More »
