Summary

Bacterial Data include results of incubations of lakewater bacteria with dissolved organic matter extracted from Colorado glacier or rock glacier outflows in 2015. Cells were counted pre- and post- incubations. The “Counts” tab is the number of cells counted in each view of the microscope using the acridine orange method. “C Calculations” tab is the calculation of carbon as bacterial biomass from cell counts. ”Change in cell counts” is the difference in the number of bacterial cells from the pre-incubation microbial culture and in each assay bottle after the biological oxygen demand incubation. The third tab, “Carbon use efficiency” is calculated as the amount of DOM from oxygen demand assays converted to microbial biomass as carbon. [...]

Purpose

Data were collected to identify the ability of bacteria to metabolize dissolved organic matter from two distinct glacier types, ice and rock glaciers. Rates of bacterial metabolism and dissolved organic matter compounds before and after laboratory incubations are presented. These data could be used to compare how the different contributions of ice glacier and rock glacier dissolved organic matter to high alpine lakes and streams influence ecosystem processes.
