WebJan 14, 2024 · Abstract. Repeated sampling of spatially distributed river chemistry can be used to assess the location, scale, and persistence of carbon and nutrient contributions to watershed exports. Here, we provide a comprehensive set of water chemistry measurements and ecohydrological metrics describing the biogeochemical conditions of … Webin each container were compared to the conditions in the stream itself. Time series data show that DIC was lower upstream and decreased more throughout the day. In chambers, the ΔDIC: ΔDO ratio is consistent with stream photosynthesis-respiration stoichiometry at both sites, while in streamwater, the ΔDIC: ΔDO ratio is much lower downstream.

WebThe reflux system in a typical industrial distillation column. Reflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial [1] and laboratory [2] distillations. It is also used in chemistry to supply energy to reactions over a long period of time.
