Dive R483  
      Dive Plan: High resolution survey of Mkr-33 using the Sit camera and Imagenex. Elevator will be used to gather experiments from Mkr-33. Suction sampling will be done there and at other active vents to the north.  
      Time-lapse camera will be brought up in the arm of ROPOS.  
      ROPOS Configuration: Biobox, Slurp Sampler, Gas Tights, Imagenex, and the other cameras.  
      Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions.
