Summary:
The Coast Guard vessel CCGS Nahidik will be used as a research platform to conduct offshore surveys in the Beaufort Sea. A regional grid of survey lines which were first surveyed in the1980's will be resurveyed as follows: (1) using a 300kHz short range multibeam echo sounder (Simrad EM 3000) to produce along-track maps of the topography and character of the seabed. These tracks will be approxi...

Summary:
The amphibious vehicle will be mounted with an echosounder, sidescan sonar, subbottom and seismic profiling equipment to run a test survey along the coast of the Tuktoyaktuk Peninsula. The CCGS NAHIDIK will tow a sidescan sonar system over the seafloor to rerun track lines surveyed in previous years to allow for the detection and measurement of the characteristics of new scours on the seafloor of ...
