one of the discovery channels has a great episode on light and this type of illusion

You mean they have something other than reality and lifestyle shows? They are regressing!

It is caused by a certain set of atmospheric conditions similar to the illusion of an oasis in the desert.

It's called Fata Morgana.

I am 93 and have had AMD for a few years, and have had the injections. The round thing you see is an air bubble that sometimes goes in with the injection and is floating in the liquid inside the eye. The reason that it is at the bottom is that it is inside the eyeball and hasn't gone through the eye's lens in order to get inverted. It is in fact at the top of the inside of your eye. Yup. Everything you see is downside-up:)

I rather think the ship is on the water, all right; different currents make the water appear different colors, so the edge of the "blue" water isn't the horizon. the horizon is higher and blends in with the sky.
Just a comment: if the ship was beyond the horizon, its refracted image would be upside down. I've seen it on Lake Michigan. Peace. KJN

Be of good cheer. KJN
