Phytoplankton bloom research. Scientist retrieving a plankton net from a river while a graduate student and hydrologist conduct water-quality sampling. These samples will be used in studies that examine whether urea pollution in the watershed is linked to periodic blooms of Pseudonitzschia sp. phytoplankton. Photographed in a tributary of the Manokin River, Maryland, USA.
