Fugro GeoServices has successfully completed the fieldwork portion of a shallow hazards survey in Alaska’s Chukchi Sea for Shell Exploration and Production. Data processing is currently underway, with the first set of interpretation and reporting deliverables scheduled for month’s end. Additional follow-on work is expected to continue into the new year.
Fugro accomplished the surveys over a period of two months. Acquisition involved specialized equipment customized for the arctic environment and to meet Alaska outer continental shelf permitting requirements, as published by the federal Minerals Management Service agency.
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.
