Diatomaceous Earth, SEM
Diatomaceous Earth. Coloured scanning electron micrograph (SEM) of diatomaceous earth consisting of fossilized diatoms. This sample is from Loch Cuithir on the Isle of Skye, Scotland. Diatoms are single-celled planktonic algae. The diatoms create a shell (frustule) of silica around themselves for protection and support which is readily fossilised. Rock formed from diatom shells is called diatomite or diatomaceous earth. It is used industrially as a filter for purifying liquids. Magnification x290 at 10cm wide

EDITORS COMMENTS
This print showcases the intricate beauty of Diatomaceous Earth, a substance composed of fossilized diatoms. Taken with a scanning electron microscope (SEM), the image reveals the vibrant colors and delicate details of this ancient material found in Loch Cuithir on the Isle of Skye, Scotland. Diatoms are single-celled planktonic algae that possess an extraordinary ability to create a protective shell made of silica. Over time, these shells accumulate and become fossilized, forming what is known as diatomite or diatomaceous earth. The rock formed from these diatom shells has various industrial applications, most notably as a filter for purifying liquids due to its high porosity. At a magnification level of x290 and measuring 10cm wide, this SEM micrograph offers us an up-close look at the fascinating structures within diatoms. The intricate patterns and symmetrical arrangements highlight their remarkable adaptability in creating such elaborate frustules for support and protection. The significance of this photograph extends beyond its aesthetic appeal; it serves as a reminder that even microscopic organisms have played a crucial role in shaping our planet's geological history. Through scientific exploration and visual documentation like this one by Science Photo Library, we gain valuable insights into nature's wonders that often go unnoticed by the naked eye.
