The study, published in the international scientific journal “Science of the Total Environment,” highlighted the location of these beaches in Greece and their remarkable sand composition. In this study, a team of researchers from the University of Athens analyzed a massive dataset of satellite imagery and historical beach data to determine the whiteness of the sand. The analysis involved examining the spectral reflectance of sand, which is a measure of how much sunlight a particular sand grain absorbs or reflects.
The research also revealed that the sand at Marmari Beach is composed of fine, white quartz grains. These grains are so fine that they are almost invisible to the naked eye. This characteristic contributes to the beach’s pristine appearance and its ability to reflect sunlight effectively.
This process allowed them to analyze the whiteness of the sand by comparing the RGB values of the sand to a standard white. The study also involved a more complex analysis of the sand’s composition. They used a combination of techniques, including X-ray diffraction, scanning electron microscopy, and chemical analysis, to determine the mineral composition of the sand. This allowed them to understand the factors that contribute to the whiteness of the sand. Finally, the study also considered the impact of environmental factors on the whiteness of the sand.
