Clouds of tan and blue and green line Italy’s eastern shore in this natural-colour image from April 6, 2010, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.
The colour is sediment billowing out from the shore into the Adriatic Sea. High concentrations of sediment are tan coloured. As the dirt disperses, the water turn pale blue green.
The sediment probably comes from run off after spring rain showers or from melting snow in the Apennine Mountains. Numerous rivers link the mountains to the coast. The rivers are pale, faint tan lines that cut across the green landscape.
