I get a bit loopy after siting at the microscope for hours. Inevitably, I began doodling on the lab ordering board. I now feel my circle-drawing skillage should be displayed publicly.
This first drawing is of common marine microbes (Cytophaga-Flavobacteria, Roseobacter, SAR11, Gamma-proteobacteria) and their affinity for dissolved organic matter (DOM) and other particulate junk floating in the ocean. Some like it (C-F) and others don't so much. SAR11 seems to compete better under low-nutrient conditions. More than you ever wanted to know about marine microbes :)
