Elac SeaBeam 3050
Apart from bathymetric data for sea charts, the SeaBeam 3050 multibem system also registers side scan data for more detailed object identification and bottom classification (for instance sand ripple or rocky areas).
For analysis of the water column, water column data are used (water column imaging). They allow depiction of objects not only lying on the seafloor but floating in the water column (plankton, fish schools, according to distance and size). Further information about sea floor structure can be gained by the calibrated back scatter values.
SeaBeam 3050 is fully real-time compensated for roll, pitch and yaw and allows a continuous full coverage, a second journey for filling of gaps is therefore not necessary. The dual ping generates two full swaths during one transmission cycle, this also saves costs, since it doubles the maximum speed up to 12 knots, at a 140° swath with 1 x 1° resolution.
Data density increases due to the dual ping, smaller objects are detected more often and can therefore interpreted as data rather than as measuring errors. Due to its frequency of 50 kHz, the SeaBeam 3050 is the ideal tool for mapping of the continental shelf. It offers excellent depth and coverage (up to 3000 m depth and 4000 m seafloor coverage). High resolution data can be used for detection of gas bubbles in gas hydrate fields.
