Seafloor gravity and height surveys

We carry out surveys in shallow or deep water. We can also work in the transition zone.

Seafloor surveys may be divided into three categories, with some different instrument and survey requirements, as described below.

Height changesSubsidence or uplift can be monitored with pressure-only surveys, using a smaller instrument package than ROVDOG.
