1. Single beam bathymetry is widely used in marine geologic survey. Tidal calibration is very necessary to guarantee correct results of the bathymetry.

2. Satellite remote sensing, bathymetry and high-resolution seismic data have been used to examine the marine geo-hazards in the modern Yellow River delta.

3. It is barely ten since systematic deep ocean bathymetry revealed the structure of rifts , fractures and trenches associated with sea floor spreading.

4. "Understanding the bathymetry and geological history of the Arctic is an important part of understanding global climate change, " said Mayer.

5. In a multi - beam bathymetry system, phase detection is a key for achieving super - wide coverage.

6. The SeaBat7125-E provides high-resolution bathymetry and imagery data in real time for detailed 3D representation of underwater features and seabed conditions.
