OSIL's Dynamic Calibration Laboratory Well Used12/11/2008 |
| 
OSIL are now responsible for the calibration of over one thousand instruments in their dynamic, high precision calibration laboratory. The regular calibration of monitoring instruments is required to ensure that the instrument is working within the manufacturer's specification and providing the highest quality data possible. Typical instruments that OSIL calibrate include Salinometers, CTDs and SVs and Multiparameter Sondes. |

Hydrographic Survey of Riverbed Erosion |
Members of the US Geological Survey were filmed while 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 analyses 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.
