This image acquired by Landsat 8 shows colorful swirls of suspended sediments & phytoplankton along the shores of the Manitoba Great Lakes! The lakebeds are covered in fine-grained silt, clay, and calcium-carbonate sediments, which give some lakes their chalky blue hues. Norman Kuring, a retired researcher from NASA’s Ocean Biology group, applied color-filtering techniques to the image to draw out these fine details in the water. The features would not be as apparent to the unaided human eye.
