The Johnson team departed Honolulu, HI today on a 1 month research cruise heading towards San Diego, CA to study the effects of climate change on open ocean ecosystems. The research cruise is the third in a series designed to map and characterize key microbial populations in the ocean as […]

The Johnson Lab was joined by local science teacher Jeff Carr from Camp Le Jeune High School and participated in Ocean Sampling Day, which is part of a coordinated effort to characterize oceans from around the globe on the summer solstice. Our participation was part of an on-going ocean acidification […]
Prochlorococcus, the smallest but most abundant marine primary producer, plays an important role in carbon cycling of the global ocean. As a phototroph, Prochlorococcus is thought to be confined to the euphotic zone, with commonly observed maximum depths of ∼150–200 m. But here we show, using flow cytometry and cellular […]
Sara Blinebry joined the team as a research technician whose work will focus on using algae as a source of biofuels. Sara was previously a member of the group as an intern while working towards her degree. Prior to rejoining our group, Sara worked with the core molecular facility at […]
Alyse Larkin participated in the Scientific Research and Networking (SciREN) event hosted by the UNC Institute of Marine Sciences at the Pine Knoll Shores Aquarium. Alyse shared her presentation, “Plankton Power: How Phytoplankton Shape our World,” with over 65 elementary, middle, and high school teachers from all over North Carolina […]
Yajuan Lin received her PhD in Marine Sciences and Conservation from Duke University. Dr. Lin’s PhD thesis title was “The Growth and Activity of Genetically Diverse Prochlorococcus” and her work focused on using molecular techniques to quantify the activity of specific ecotypes (genetically diverse, ecologically distinct types) of Prochlorococcus. Several […]
The Duke Marine Laboratory welcomed Prof. Jed Fuhrman from USC. Prof. Fuhrman presented lectures to Marine Microbial Ecology and Biological Oceanography classes taught by Zackary Johnson and Richard Barber, respectively. Prof. Fuhrman also gave a fascinating seminar titled, “Three decades of discovery in marine microbial ecology” documenting the exciting progression […]
In the open ocean genetically diverse clades of the unicellular cyanobacteria Prochlorococcus are biogeographically structured along environmental gradients, yet little is known about their in situ activity. To address this gap, here we use the numerically dominant Prochlorococcus clade eHL-II (eMIT9312) as a model organism to develop and apply a […]
Maggie C., a sixth grader at Saint Francis Xavier School in Utah (and Johnson Lab member in abstentia), is interested in math and science and in particular how things are interconnected. She used a series of randomly generated numbers to select a city, a university offering a PhD, a department, […]
Second-year PhD student Alyse Larkin recently participated in the “Invite a Scientist” program, which is organized by the North Carolina Science Festival. Alyse visited Mrs. Kathleen Marshall’s 6th grade science classes at Havelock Middle School where she spoke to the students about her research, how she became a scientist, and […]
