Tides

Another thing we went to see in Nova Scotia were the tides. Specifically the Bay of Fundy tides. The afore mentioned Roy Bishop is an expert on tides and we were able to see a number of tidal related phenomena while visiting.

I've lived near tidal areas all my life. But the tides around me have meant the gain and loss of a few meters of beach, or a stream raising by a meter or so. The Fundy tides are in a different league altogether.

Pictures of this boat can be found all over the interwebs and in plenty of books as well. But when in Rome ...


... take pictures. Good advice wherever your travels take you.


Look at those two images. And now think about all of the water that moves in and out with the tides. That's a lot of water sloshing around.


This is Cape Split. There is a four mile trail out to the point.


This is the view from Cape Split (it was a pleasant walk). The turbulence you see is the tide coming in. There is more water moving into the Minas Basin than that flowing in all the rivers in the world. Yep, that's a lot of water.


This is a tidal bore. That means river running backwards.


The incoming tide actually reverses the river flow, with more water flowing upstream than down.

I came across a quote while wandering the web to the likes of, "with the exception of the tidal bore, watching the tides is like watching grass grow. But it is the enormity of the event that fascinates." I whole heartedly agree.
