First Magnetometer survey!!!

After learning how to collect my data with the magnetometer and how to set up a search area (Grid), it was time to get hold of a couple of brave souls to help me get it done. Andrew Mulherin and Paul Lavoie where the brave ones I managed to convince. My dad (Viateur Ouellette) wanted to come lend a hand but at the last minute he came down with the flu . However he did agree to lend me his handheld GPS device.

We first located what I have called pier #2 and Pier #3 on the ice. We then measured a 60 meter (200 feet) by 40 meter (130 feet) rectangular grid on the ice and surveyed 4 lines (20 meters apart) perpendicular to the bridge alignment and 3 lines (20 meters apart) parallel to the bridge alignment. On those seven lines, five readings were taken at 5 meter intervals. This would cover enough area to detect any possible debris at the bottom.

The bridge in the bacground is the last CPR bridge to cross the St. John River in Grand Falls. The CPR line in Grand Falls has been abandoned for a while now but the bridge still serves as part of the New Brunswick trail system.
