Bryn Warren, guest student in the WHOI Biology Department, and WHOI postdoctoral fellow Luciano Fernandes process mud samples collected from the Gulf of Maine in October 2007. The researchers were part of an expedition on R/V Oceanus and led by Bruce Keafer to investigate the abundance of cysts, or seeds, of harmful algae in New England waters.
