Two videos are presented here showing the effect of DND blasting on Bentinck Island on the sea lions at Race Rocks. The first is from October 7 and the second was done by student s on the project week on November 8, 2002, (not Oct 7 as stated in this draft version of the video) . The students from Lester Pearson College who were out for a project week were able to catch the images of the impact of these blasts on the first day from the science centre window and on the second day from the top of the light tower. In the tower, they interviewed Mike Demarchi of LGL who is currently doing a $50,000 contract for the Department of National Defence to monitor the impact of these blasts and to compare them with other disturbances at Race Rocks.
