Do panning spots ever appear in the ocean?

I thought I saw one near the docks at Ginger Island, but it disappeared when I got out the pan.

I’m pretty sure it’s only ponds, rivers, and lakes. No saltwater as far as I know.

Only the Beach (on the mainland) is explicitly excluded.

You can get panning spots in the Ginger Island ocean.

I have a feeling that I've seen panning spots at the beach during the three days of the night market, but not at any other time

This is probably something @BlaDe would know how to verify
