WHOI engineer Amy Kukulya uses a tracking ranger to monitor the progress of a REMUS 100 vehicle during a deployment in Lake Rotomahana, New Zealand. A transducer connected to the ranger dangles in the water and receives periodic status messages from the REMUS with information about the vehicle's depth, speed, heading, and other attributes. On the shoreline behind her, steam rises from fumaroles stemming from a geothermal field that formed after a volcanic eruption in 1886 destroyed the fields that had given rise to the Pink and White Terraces.
