Regulation of spatial temporal variability carbon flux six hard-water lakes northern Great Plains
2014/4/17
Six hard-water lakes were sampled May-August for 14 yr in a 52,000 km2 catchment to identify the mechanisms that regulate the spatial and temporal variability of net atmospheric exchange of CO2 of lak...
Spatial and temporal variability of prairie lake hydrology as revealed using stable isotopes of hydrogen and oxygen
Spatial temporal variability hydrogen and oxygen
2014/4/17
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern
Great Plains, but little is known of how the relative importance of these processes may vary...
