The Florida Keys are a coral cay archipelago, formed from the skeletal remains of coral reefs and other marine organisms. The shallow waters and the presence of coral reefs are crucial in determining the color of the sea.
Shallow Waters and Coral Reefs
The waters around Key West are relatively shallow, with an average depth of about 10-15 feet. This shallowness allows sunlight to penetrate the water, illuminating the sea floor and contributing to the vibrant blue color. Coral reefs, which are abundant in the area, also reflect sunlight, enhancing the blue hue. The reefs themselves are made up of coral polyps, tiny animals that secrete a hard, calcium carbonate exoskeleton. As these polyps grow and die, they leave behind a structure that provides a habitat for a diverse array of marine life and influences the local waterchemistry.
The Role of Sediments and Reflection
The sediment composition of the sea floor around Key West is another factor influencing the water’s color. The sea floor is primarily composed of white carbonate sand, which reflects sunlight and contributes to the water’s clarity and blue appearance. Additionally, the reflection of light from the surface of the water and the scattering of sunlight by the water molecules themselves play critical roles in the perceived color. When sunlight enters the water, it encounters tiny molecules of water and other substances, which scatter the shorter, blue wavelengths more than the longer, red wavelengths. This phenomenon, known as Rayleigh scattering, is responsible for the blue color of the sky and also contributes to the blue appearance of the water.
Marine Life and Water Chemistry
The diverse and thriving marine life in the waters around Key West also affects the coloration of the sea. The presence of various species of phytoplankton, microscopic plants that form the base of the marine food web, can influence the water’s color. Some types of phytoplankton contain pigments that can give the water a greenish or brownish tint, but in the case of Key West, the abundance of blue-green algae and other microorganisms contributes to the blue color.
Pigments and Phytoplankton
Phytoplankton contain different pigments that absorb and reflect various wavelengths of light, which can alter the apparent color of the water. For instance, chlorophyll, the green pigment used by plants for photosynthesis, absorbs blue and red light and reflects green light. However, in the waters of Key West, the types and concentrations of phytoplankton are such that they enhance the blue color rather than giving it a greenish hue. The clarity of the water, the depth, and the specific species of phytoplankton present all contribute to the overall blue appearance.
Water Clarity and Transparency
The exceptional clarity and transparency of Key West waters are due to the absence of significant amounts of suspended sediments and pollutants. This clarity allows sunlight to penetrate deeper into the water, illuminating the sea floor and enhancing the blue color. The transparency also enables the growth of coral reefs and supports a rich diversity of marine life, further contributing to the distinctive color of the waters.
