A swirling ribbon of milky blue colored the waters off Newfoundland in late July, 2012, marking the site of a continuing bloom of phytoplankton in the North Atlantic Ocean. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on July 27 as it passed over the region. Image and more information is found on MODIS website.
