We offer a number of oceanographic and environmental services to complement bathymetric and structural surveys.

Current profiling can be used to inform asset managers of scour and erosion processes.

ADCPs are hydroacoustic current meters which use the Doppler effect to measure current water velocities throughout the water column. The ADCP emits a sound burst along downward angled beams, with echos returning from scattered particles carried by water currents. A second burst can then be transmitted to track seabed movement. 

By analysing these returns, various measurements can be made:

  1. Direction and speed of current - throughout the water column 
  2. Distribution of sediments in the water column
  3. Speed over ground and travel path of the ADCP
  4. Distance to the boundary - whether this is seabed for downward-facing beams or, if facing upward, to the surface.

ADCP's can be deployed either on a vessel to examine a large area such as a river, or stationed at a single location over a sustained period. Suspended Sediment can also be quantified to aid understanding of sediment transport. 

Vessel-mounted ADCP deployment allows asset holders to understand the hydrodynamics of a large area, such as a river.

Seabed mounted ADCPs are used to understand the hydrodynamics of a single location of interest.
