Description:
Antarctic Peninsula Coast. Glacial ice is a different color than regular ice. It is blue because the dense ice of the glacier absorbs every other color of the spectrum except blue--so blue is what is seen by the human eye. Sometimes the glacial ice appears almost turquoise. Its crystalline structure strongly scatters blue light. The ice on a glacier has been there for a very long time and has been compacted so that its structure is different than the ice normally seen. Glacial ice is different than the frozen water you get out of the freezer and is not just frozen compacted snow. There are other things in the ice that make it different because glaciers move through rock and soil as they carve their way down a slope.
