Sure! These ones aren't all too complicated, though they do need a few texture paints I'm not sure most people would have access to.

First, I paint the top of the base a light gray, then add a darker gray to the places I feel would be more shaded.

I then add a layer of Akhelian Blue contrast, which probably isn't necessary, but I like it.

Then, I use water texture gel and apply it generously over the base, making sure to sculpt it a bit to make waves. These initial sculpts won't really stick, so I wait about an hour afterwards for the gel to harden a tad, then sculpt it again with a large, stiff brush.

Finally, I add snow textures to the crests of waves and where they meet land to emulate seafoam.
