Jacques Descloitres, MODIS Land Rapid Response Team, NASA/GSFC
A bright blue phytoplankton bloom is peaking through the clouds south of the island of Newfoundland in the Atlantic Ocean off the Canada coast. When the bloom appear whitish, as the one in this true-color image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite, it can sometimes indicate the presence of coccolithophores, phytoplankton that encase themselves in scaly shells made out of calcite (chalk). This image was acquired on July 27, 2002.
