The Johnson Lab participated in Duke University Marine Lab’s annual Open House on Saturday, August 3rd. Members of the community were welcomed to Piver’s Island to visit campus and learn about the variety of ongoing research at DUML. At their station inside the Repass Center, the Johnson Lab explained their research on Prochlorococcus and the importance of marine phytoplankton to people of all ages. The public also viewed photos and videos from the recent POWOW research cruises, while graduate students explained how they retrieve and sample water at different depths in the ocean.
