Caption reads: "Figure 1. The biotic systems that have built and now maintain the biosphere also influence the cycles of carbon, nitrogen, sulfer, and other elements. The general pattern of movement is a series of exchanges between the atmosphere, the land, and the sea. Human activities worldwide have mobilized significant additional quantities of biotically important substances, including toxins, and have modified the natural cycles."Created: 1979

This is a Winogradsky column that Joseph Vallino uses in a SES course on Methods in Microbial Ecology. Almost every bacterial metabolic process that occurs on Earth also occurs in these columns that are simply constructed by placing freshwater or marine sediments augmented with a carbon source (such as saw dust) and fertilizer (N and P) in a column and topping it off with either fresh or sea water. Julie Huber is a co-instructor in the course.
These are methanotrophic microcosms that are being used to develop and test new approaches to modeling microbial biogeochemistry using thermodynamic approaches (namely, the principle of maximum entropy production).
Caption reads: "Figure 4: A diagrammatic model of carbon and nitrogen flow in an estuarine ecosysem that emphasizes inputs of organic carbon and nitrogen and inorganic nutrients from upland watersheds and processing by the estuarine food web. Compartments of the mathematical model are shown in the box. The inorganic nutrients compartment comprises both ammonium and nitrate. The organic matter compartment comprises three distinct components: labile nitrogenous material, labile carbohydrate material and refractory nitrogenous materal."Created: 1993
