Alvin engineer and pilot Danik Forsman holds a seafloor heat blanket used to measure the heat flow from the seafloor. Scripps Institution of Oceanography scientist Ross Parnell-Turner reads its weight. Prior to every dive by the human-occupied submersible Alvin, careful measurements of the science payload are necessary so that members of the Alvin Team can adjust the sub’s buoyancy.
