Spectrum is to reprocess up to 10,100 line km 2D of their seismic data offshore the Andaman Islands frontier on the east coast of India for India's Directorate General of Hydrocarbons (DGH), and to license the results to third parties. The new agreement follows the Indian government's launch of the NELP VIII Licensing Round that comprises 8 blocks offshore Andaman Islands. Many of the lines proposed by Spectrum for reprocessing cross this frontier area.
This announcement follows the completion of Spectrum's reprocessing of 12,000kms seismic data offshore West Coast of India in 2007.
NELP-VIII was announced on April 9th and bids will close on October 12th 2009.
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.
