RS Aqua has completed the delivery of a Directional Waverider Mk III system to the UK Met Office's Marine Engineering Unit based at the NOC. This was realised just before Ocean Business in the last week of March.
The Waverider system is to be used as a "standard" during the Met Office's imminent evaluation of a number of wave sensor units aboard Data Buoy platforms.
U.S. Geological Survey were out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyzes the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
