Bathymetry

Andromede Oceanology runs single- and multibeam bathymetry surveys using compact systems that work anywhere in the world and on any kind of ship.

The bathymetry systems we use give high-resolution images of the seabed (Digital Terrain Model) which form the basis for a map in the form of colour gradients and/or isobaths.

Advantages of the multibeam echosounder (GEOSWATH):

  • broad swathes, about 5 times the depth below the boat
  • high precision, greater than the IHO Special Order specification
  • very high data density (measurement points) that is practically constant all the way down. The system can filter or take the mean of points in a grid cell for the same resolution
  • capacity to process data to create a digital terrain model which helps to define
biocenosis.

Advantages of the single-beam echosounder (CEEDUCER PRO):

  • easy to use
  • low cost
