As part of the IGERT in Cross-Scale Biogeochemistry and Climate (CSBC), ZIJ gave a talk at Cornell University titled “Using molecular tools to better understand the ecology and biogeochemistry of marine phytoplankton” The talk, part of the Biogeochemistry and Environmental Science and Sustainability seminar series, focused on the Johnson lab’s […]

The Duke-UNC Oceanographic Consortium held its annual meeting at the Duke Marine Lab November 16-17 to discuss recent progress of marine scientists at partner institutions and plan future collaborations. Presentations ranged from eutrophication in lakes of China to atmospheric deposition of organics in the global ocean. ZIJ presented a talk […]
The Cary Institute of Ecosystem Studies hosted a colloquium on “Climate Change and Species Interactions: Ways Forward” The purpose of the workshop was to facilitate the rapidly growing understanding of the links between climate change and biotic interactions and to help guide future research and application. As the climate continues […]
With the POWOW2 cruise less than two months away, the Johnson Lab held a training session for several of the undergraduates that will be joining us on the trip as part of their independent study projects for the Spring 2013 semester. Tristan, Jennifer, Molly and Catherine spent two days in […]
Marine microbial communities are complex and dynamic and their ecology impacts biogeochemical cycles in pelagic ecosystems. Yet little is known about the relative activity of different microbial populations within genetically diverse communities. Here we use rRNA as a proxy for activity to quantify the relative specific activity (rRNA/rDNA) of eubacterial […]
The Johnson Lab visited the American Society for Microbiology, North Carolina’s annual conference this past weekend. We made the long trek up to the big city (a.k.a. Raleigh) on Friday and spent all day Saturday learning about some great microbiology projects going on throughout North Carolina. The ASM conference […]
The industrial-scale production of biofuels from cultivated microalgae has gained considerable interest in the last several decades. While the climate benefits of microalgae cultivation that result from the capture of atmospheric CO2 are known, the counteracting effect from the potential emission of other greenhouse gases has not been well quantified. […]
The Johnson Lab traveled to Knoxville TN as part of a planning meeting for the upcoming POWOW cruises. Working the project co-PIs Zinser and Wilhelm labs and joined by the Buchan and Campagna labs, who will also be part of the field projects, all with UTK, we refined cruise tracks, […]
Samantha Rose, a summer NSF-sponsored research experience for undergraduates (REU) student from Drury University, gave her final presentation on the effects of temperature on the activity of different types of Prochlorococcus . Her study focused on two abundant high-light strains of Prochlorococcus, one normally found in colder temperatures (MED4) and […]
Summoning deep creativity and mad culinary skills, the Johnson Lab team won the inaugural ‘Iron Chef’ competition by preparing 4 dishes with the secret ingredients. Deep-dish eggplant pizza (shaped like melting ice sheets), chocolate almond torte, watermelon canapes (in the form of various phytoplankton, of course), and ‘global warming’ curry […]
