ALVIN returns from its first dive with a biobox full of tube worms collected from the top of the S&M (smoke and mirrors) structure. From left to right: Chuck Fisher, Kathleen Scott, Anja Schulze, and Mark Van Horn. Anja is a biologist from the University of Victoria, and Chuck, Mark, and Kathleen are biologists from Penn State University. The big yellow objects are transponders.
