Initial results are expected at the end of this year.
A survey of lakes in the Rotorua region will help scientists build a more complete picture of geothermal resources and volcanic hazards under the Bay of Plenty.
The electromagnetic survey involves a technique called magnetotellurics, or MT, which helps scientists identify where geothermal fluids may be present deep within the earth. It's the first time this technique, which measures low-frequency electromagnetic waves in the Earth's crust, has been used in New Zealand lakes.
The survey is a joint project involving GNS Science and Bay of Plenty Regional Council and will collect data at Lakes Rotorua, Tarawera, Okataina, and Rotoiti.
The findings will complement existing data which has already been used for the sustainable management of geothermal fields, for exploration of new deep geothermal resources, and for management of volcanic hazards.
