Tubeworms Through the Years

WHOI geologist Susan Humphris (center, in blue sweatshirt) and colleagues inspect tubeworms and other samples in Alvin‘s collection basket during a 2002 expedition to the Galápagos Rift, where seafloor hydrothermal vents were first discovered in 1977. The main objective of the cruise, which was highlighted on the Dive and Discover web site at the time, was to investigate how the vents and their animal and microbial communities had changed over the years.(Photo courtesy of Woods Hole Oceanographic Institution Archives)
