All surveys are GPS based and the position accuracy can be adapted to the customers needs. We perform surveys up to water depths of 300m.
The parametric sonar SES 2000 allows for a differentiation of sediment layers with penetration depths of up to 20m. High vertical and horizontal resolutions can be reached.
Based on the processing of high frequencies (100-200 kHz) and lower frequencies (4 - 38 kHz) magnitudes of fuid mud and more consolidated sediment can be derived.
Based on sediment-specific reflectance intensity the sediment at the lake bed can be classified. Maps of changing sediment types can be created with high spatial resolution.
