WHOI News Release

Two Oceanographic Systems Laboratory, WHOI, REMUS-100 AUVs were used in February 2011 to search, map and classify the lake-floor of Lake Rotomahana (New Zealand) in hopes of locating the lost eighth wonder of the world, the Pink and White Terraces.  The two vehicles known as Darter and Gudgeon (named after WW II submarines) were modified and outfitted with a unique suite of sensors to most efficiently and effectively characterize the lake's water properties as well as physical features.

Primary objectives for the WHOI-supplied instrumentation were to collect high-resolution bathymetric and side-scan sonar data of the lake bed with correlative water properties information including pH, Eh, temperature and turbidity, and 3-axis fluxgate magnetometer data.  For the lake surveys, the REMUS 100 AUVs were fitted with mounting brackets to accept NOAA-PMEL ORP-MAPR sensors, to aid in characterizing the water properties and localizing any sources of hydrothermal activity.  In addition, the REMUS AUVs were modified to accept SBE pH sensors.
