The Department owns an
Edgetech LC-100 Sidescan Sonar unit, capable of imaging to depths approximately
200m below the surface. The unit has a maximum range of 300m either side
of the tow-fish. The depths to which the sonar unit can operate are dependent
on the cable length available, which is currently 200m. Image resolution
allows clear display of the data, with a maximum of 1024x768 pixels.
The equipment is used for creating underwater mosaics of the geomorphology of the sea-floor. The acoustic data is not suitable for identifying the biology of the sea-floor, rather its structure and texture. The imagery can be used to measure the size of features, for example the image to the left shows sand-ripples that could be measured directly from the sonar image. Projects using this equipment include:
