Phytoplankton blooms in Seal Cove in Conception Bay South are shown in this Sunday Sept. 8, 2019 handout image. The blooms have turned some eastern Newfoundland waters bright turquoise over the last week. ST. JOHN'S, N.L. -- Phytoplankton blooms are putting on a unique and colourful show in the waters along Newfoundland's eastern coast.
Federal fisheries and oceans scientist Cynthia McKenzie says the vibrant colour is reflected by chalky calcium carbonate scales on the tiny phytoplankton cells.
Thanks for the info. Just returned from NL & wondered about the water colour.
