Researchers recover the "microprofiler" and return it to the deck of the research vessel Atlantis during the LADDER 3 cruise along the East Pacific Rise in November 2007. Working from left to right are Brian Hogue (WHOI), Matt Schwartz (University of Western Florida),
Louis St. Laurent (Florida State University), Jerry Graham (Atlantis crew, WHOI), and Eric
Howarth (Florida State). The microprofiler
measures turbulence and mixing between hydrothermal vent fluids and deep ocean waters.
