  Citation × Citation Citation Abstract Copy Title: Glacial greenhouse-gas fluctuations controlled by ocean circulation changes Author: Schmittner, Andreas, Galbraith, Eric D. Earth's climate and the concentrations of the atmospheric greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) varied strongly on millennial timescales during past glacial periods. Large and rapid warming events in Greenland and the North Atlantic were followed by more gradual cooling, and are highly correlated with fluctuations of N2O as recorded in ice cores. Antarctic temperature variations, on the other hand, were smaller and more gradual, showed warming during the Greenland cold phase and cooling while the North Atlantic was warm, and were highly correlated with fluctuations in CO2. Abrupt changes in the Atlantic meridional overturning circulation (AMOC) have often been invoked to explain the physical characteristics of these Dansgaard–Oeschger climate oscillations, but the mechanisms for the greenhouse-gas variations and their linkage to the AMOC have remained unclear. Here we present simulations with a coupled model of glacial climate and biogeochemical cycles, forced only with changes in the AMOC. The model simultaneously reproduces characteristic features of the Dansgaard–Oeschger temperature, as well as CO2 and N2O fluctuations. Despite significant changes in the land carbon inventory, CO2 variations on millennial timescales are dominated by slow changes in the deep ocean inventory of biologically sequestered carbon and are correlated with Antarctic temperature and Southern Ocean stratification. In contrast, N2O co-varies more rapidly with Greenland temperatures owing to fast adjustments of the thermocline oxygen budget. These results suggest that ocean circulation changes were the primary mechanism that drove glacial CO2 and N2O fluctuations on millennial timescales.

  Citation × Citation Citation Abstract Copy Title: Snowpack characteristics in a post-wildfire environment: an examination of the Shadow Lake fire region Oregon Cascades Author: Roses, Tyler As global temperatures continue to rise there has been an increase in forest fire frequency and severity. With larger areas of forest being burned it is increasingly important to understand how forest fires effect snow processes. Previous research shows that burned areas will accumulate more snow and that this snow will melt much faster when compared to unburned forests. These conditions can lead to high magnitude stream flows which have broad implications for reservoir managers, flood control, and groundwater recharge. This project studied the post-wildfire effects on accumulation and ablation rates of snowpack in a recently burned forest. The Shadow Lake fire in the Mt. Washington Wilderness near Sisters, Oregon burned over 10,000 acres in the late summer of 2011. In situ snowpack measurements were made in both burned and unburned forest areas. Graphs were created in order to analyze these areas for similarities and differences between snow depth, density, temperature, and concentration of burned and unburned forest debris (bark, needles, etc.) within the snowpack.

  Citation × Citation Citation Abstract Copy Title: Soil respiration flux in response to soil temperature, moisture, and pH Author: Murphy, Bailey Soil respiration has been identified as one of the largest natural sources of CO₂ to the global carbon cycle. Small alterations in the magnitude of soil respiration can have potentially large effects on concentrations of atmospheric CO₂ , making the rate at which respiration occurs of great scientific interest (Martin et al. 2012; Schlesinger & Andrews 2000). This experiment addresses the relationships between the rate at which soil respires and the temperature, moisture content, and pH of the soil. Soil respiration is largely dependent on factors that influence the chemical and microbial properties of the soil, as well as the plant activity. Some of these factors include soil and air temperatures, soil moisture, and soil pH. As our climate changes, these factors have the potential to be altered considerably. Understanding the relationship between these factors and the rate of soil respiration is vital to understanding the implications of an altered climate on soil respiration, and the resulting changes and feedback mechanisms in the amount of CO₂ being added back into the system. WS1 within the H.J. Andrews forest is an ideal setting for this experiment, as the contrast in soil conditions at the various survey plot locations on the North and South facing slopes of the watershed offer an opportunity for comparison of these factors.
