Abstract
This map poster shows a detailed view of the lake floor bathymetry In Lake Rotoma; at a scale of 1:12,500. There are also three smaller maps detailing free air gravity, total magnetic intensity and conductive heat-flow over the lake. The main map shows lake floor features and other subtleties that likely have not been seen for centuries. For example, the bathymetry shows Lake Rotoma; is made up of two smaller basins: one in the north and one in the south. The gravity data suggest the basement greywacke is dipping under the lake, while the magnetic data clearly demarcates the volcanics on the eastern side of the lake from the southern basin. This 663 mm by 600 mm sized map is the fifth in the Rotorua Lakes Map Series
