Objective(s): The objective of GXTÆs research is to gather data to identify, model and remove Flex Waves (acoustic waves that becomes trapped in the ice) from the records.

Project Description: This licence was issued for the scientific research licence application number 782.

The objective of GXT’s research is to gather data to identify, model and remove Flex Waves (acoustic waves that becomes trapped in the ice) from the records. Data will be gathered using geophones developed by GXT and new methods of recording and interpreting the data.

The project will involve setting out lines of geophones on the ice, and using vibrator trucks to generate an energy signal. The vibrator trucks are three tracked, 60,000lb vehicles, used one or two at a time. Other vehicles will be required (4WD pickup trucks, crew bus, fuel truck, fuel sled, tracked vehicles (eg. Tuckers), data recording truck, cat/grader for route maintenance). The main work area will be 10 to 20 m wide and the geophone spreads will be about 9 km in length. At least 1.2 m (48 inches) of ice thickness is required to support the equipment, so ice thickness will be tested before and during the work. The project window is mid-March to mid-May. The actual work is expected to take less than 28 days.

Reports will be made to HTCs and other agencies. Monitors will report on wildlife and other issues. Technical results will be proprietary information with the data stored in GXT's Calgary offices. As many experienced local people will be hired as possible (potentially more than half of the 35 person team). Some local supplies and equipment will be used, as will an existing commercial camp in Tuk.
Fieldwork will be conducted from March 17 to May 15, 2008, along a 25 – 50 km line on the Beaufort Sea ice west of Tuktoyaktuk, in the area bounded by (134° 25’ 21”W 70° 14’ 23”N), (133° 38’ 50”W 70° 23’ 17”N), (132° 28’ 10”W 69° 49’ 15”N), (133° 5’ 1” W 69° 39’ 56”N). The final location of the work will depend on accessibility and ice thickness.
