In June 2020, swirls coloured the waters of the Great Slave Lake, Canada – the world’s tenth largest lake by area and the deepest lake in North America. Between 19 and 21 June 2020, the Copernicus Sentinel-2A satellite captured these stunning swirls.

Description
English: In June 2020, swirls coloured the waters of the Great Slave Lake, Canada – the world’s tenth largest lake by area and the deepest lake in North America. Between 19 and 21 June 2020, the Copernicus Sentinel-2A satellite captured these stunning swirls. In this image, we see swirls at both the northern and southern ends of the lake. And, they are caused by very different natural phenomena. In the southern coastal areas, the thaw of the Hay river transports and discharges sediments into the lake disrupting the waters. While the northern swirls are caused by a phytoplankton bloom. The swirls range in colour and include light browns, light greens, blues and whites. The Copernicus Sentinel satellites orbit the Earth acquiring measurements and imagery using onboard sensors, some of which are particularly suited to study and monitor water quality and pollution.
