Amelia Earhart's Aircraft Search19/08/2010 |
| The International Group for Historic Aircraft Recovery (acronym TIGHAR, pronounced ‘tiger') foundation has organised several trips to Gardner Island, now Nikumaroro in the Republic of Kiribati based on the hypothesis that Amelia Earhart and Fred Noonan landed and eventually died on this remote Pacific island. For this purpose, OceanServer Technology recently loaned an Iver2 AUV outfitted with side-scan sonar to the organisation. |

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.
