Video: Live from hydrothermal vents in the Guaymas Basin

Hydrothermal vent and tube worms in the Guaymas Basin, Gulf of California.

Watch video from a ROV Jason and AUV Sentry cruise on the R/V Roger Ravelle to the Guaymas Basin the Gulf of California. This cruise was lead by Chief Scientist for Deep Submergence Anna Michel.

After a successful five to 1,500 meters, Alvin begins a transit south to continue test dives closer to Puerto Rico.

Read a feature in Cape Cod Times about Alvin’s 6500 meter overhaul and the scientists who will use the sub at its new depth.

Atlantis left Woods Hole around 2:45 yesterday with a storm building across our path to Bermuda, so we’ve taken a westerly course parallel to the coast with plans to turn 90 degrees left this afternoon and make a beeline across the Gulf Stream. That should allow us to miss the worst of what was in…

Shawn Arellano (Associate Professor, Western Washington University) gets ready to dive to the cold seep site, Green Canyon 234 (~550 m), in the Gulf of Mexico.

Shawn Arellano is a larval biologist and deep-sea ecologist and an associate professor at Western Washington University. Arellano has recently used all three NDSF vehicles as part of a collaborative project that focuses on the larvae of cold seep animals on both the Atlantic and Gulf sides of Florida. The lead principal investigator on this project…
