On 20th April, an explosion caused a fire in the rig Deepwater Horizon in the Gulf of Mexico, near Houma (LA). The rig collapsed and caused an oil spill in the Gulf. Below links to relevant articles are collected for your convenience.

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.
