Here is a picture of the shelter we built last night in order to accommodate Nick's sonar instrumentation. Once we are done on the river with the shelter, we will use it at work as a mobile winter concrete testing shelter. It's 4ft wide, 6 feet long and 7ft high.
Now everything is ready for Thursday. The ice cutting will be done the day of the survey in case we need to add a few holes.
I will explain the survey in detail tomorrow.
I'm busy working on my blog posts. Watch this space!
