Labrador Sea 2015 Glider Testing and Deployment

Testing the glider in the bay off Charlottetown. Robin controlled the glider from a van onshore while the rest of the team were out watching from a skiff.

Testing complete, it was time to deploy.

Charlottetown harbour with our deployment vessel, Little Bubbles tied up to the dock on the left. As can be seen in the foreground, ice is starting to form around the edge of the bay. In only a few more days the harbour may be completely frozen over and Little Bubbles won't be able to get off the dock. So we're deploying just in the nick of time!

The path out to our offshore deployment location from Charlottetown was riddled with numerous small islands, many separated only by narrow passages containing treacherous submerged rocks. Fortunately our experienced local crew knew the route to take to avoid these underwater hazards and navigated us out into open waters with ease. It won't be long now before this area is frozen solid and you can walk out to the islands.

Deployed! We slid the glider off its cart into the water over the side of Little Bubbles in the manner of a kid going down a slide. It shot down beneath the surface before bobbing back up again (to our relief).

Back in Charlottetown, Little Bubbles had to cut a path through the ice in order to get back to the dock. This made a disconcerting crunching noise on the boat's fibreglass hull.
