Water is a great theme, thank you, Baz. And my ducks and I are honored to have them as banner picture for this week, thank you all.
Seagulls on northern Lake Michigan
These rocks are underwater; I don't know if you can see that. The cold water of Lake Superior, far north in Canada, does not support much in the way of algae, and the water stays clear.
I took a few pictures of this pelican fishing in the surf. I don't think I posted this one before.
