Images: On the Seafloor, a Parade of Roses

Biologist Tim Shank (in hat) shows off a white crab captured during an expedition to the Rosebud vent field this spring. He explained to geologist Susan Humphris and WHOI guest Dan Dubno that the crab is a scavenger that can grow to about the size of a hockey puck. ((Photo by Amy Nevala, WHOI) )

The ?Rose Garden? vent site at the Galapagos Rift was so named in 1979 because of its thickets of tubeworms, which looked like long-stemmed red roses. (Photo by Kathleen Crane, NOAA)

A vent site found during an expedition to the Galapagos Rift in June 2005 had a concave, ring shape about 10 meters (30 feet) in diameter. White crabs crawled its perimeter, and anemones and mussels populated its center. The shape of the vent site?and its lineage to previously found sites called Rose Garden and Rosebud?suggested what the expedition would name it: ?Rose Bowl.?
