Glenn Dawson, and his crew braved the cold and icy weather to collect bathymetric data around the Essroc Quay. The crew equipped a nineteen-foot Boston Whaler boat with a single beam echosounder.

The sounder obtains depth data at a predetermined frequency as the boat moves around the harbour along a pre-planned runlines. A GNSS unit collects positional data of the transducer in real time.

This task was completed as part of Cherry Street Stormwater and Lakefilling project which is the first step to improve the area for reuse and naturalization.
