I had to wait for some work colleagues on a pier on Duluth’s Ship Canal last week. They were late. I had a camera. Enjoy the fruits of my boredom!
When my colleagues arrived, they installed a wave gauge pressure sensor off the pier that will be used to help detect and predict the presence of rip currents, which can sweep unwary swimmers out into Lake Superior. The local newspaper wrote a (front page!) story about the project. Read it here.
