Extraordinary bloom of toxin-producing phytoplankton enhanced by strong retention on the offshore Patagonian shelf
Abstract. The extensive Patagonian continental shelf in the Atlantic Ocean is renowned for its high productivity associated with nutrient-rich waters that fertilize massive phytoplankton blooms, espec...

When Chief Scientist Daniel Lauretta & #TaludContinental_IV team encountered a seafloor blooming w/these animals, he nicknamed it: beet field. While rich in color, they're not related to the ruby red root vegetable & likely a type of Anthomastus, a genus of soft corals in the family Alcyoniidae.
