| With the bathymetry data, we periodically measure the speed of sound through the water column. |
| Measuring the relief of the ocean floor, expressed as the varying depth below sea level, is the chore known as bathymetry. |
| The pre-eruption bathymetry shows a submarine extension of the Tar River valley. |
| Review and evaluate the required methods and data sets, including bathymetry and coastal topography for determining the coastal hazards. |
| Each of those sections commences with an overview of the relevant oceans, oceanography, bathymetry, and meteorology. |
| This specification also defines the information content for each of the bathymetry and water level input data sets. |
