"....Over the Ocean Blue" - or is it?



With the same atmospheric conditions, the ocean is a distinctly different color based on the depth of the water.


"The Ocean Blue" comes from the deep parts of the ocean and is shown here in a photo taken on Rincewind east of the continental shelf in a depth of 1510 fathoms (1 fathom = 6 feet).












Once closer to land, the beautiful green color develops as in this picture taken in 67 fathoms when Rincewind was about 70nm SSE of Nantucket.












It is hard to see how clear the water is when there is no frame of reference, but I looked over the transom to glance at the rudder and was surprised at how easily I could see the five feet to the bottom of the boat.
