Geological Survey of Canada
Geophysical Survey of North Head, Grand Manan Island
May 6-18, 2002

In preparation for the construction of the new ferry terminal in North Head, Grand manan Island, in 1999, dredged material from the site was placed on the seafloor adjacent to the west side of the existing terminal.  Materials taken deeper from within the excavated hole were used to cap the dredged sediments.  From May 6-18, 2002, the CCGS JL Hart and hydrographic survey launch Plover, under the direction of the Geological Survey of Canada (GSC), conducted a survey of the sediment deposition site.  The purpose of the survey was to examine whether material had leached from the disposal area.  Data was collected with multibeam and sidescan sonar, sub-bottom profiler, seafloor photographs, underwater video transects, and seafloor samples.  Specific equipment used are listed as follows:
