Blue Meridian

Blue Meridian: The Search for the Great White Shark is a 1971 non-fiction nature book by the American author Peter Matthiessen. He writes of a 17-month expedition he undertook with Peter Gimbel to photograph great whites underwater. The book recounts, then, the production of the documentary Blue Water, White Death.

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
