Late Glacial-Holocene Climate Change Recorded In Proglacial Lake Sediment Cores From The Huaguruncho Massif, Central Peruvian Andes, Dane O'Neil
Honors Theses
Alpine glaciers respond rapidly to changes in climate and the growth and decay of alpine glaciers is recorded in sediment cores extracted from lakes immediately downvalley from the margins of former glaciers. These records provide continuous archives of glaciation and climate change that complement the inherently discontinuous records of glaciation preserved by moraines. The aim of this study is to generate a continuous record of glaciation in Jaico cirque from lake sediment cores, which is located on the southeastern side of the quartz-monzonite dominated Huaguruncho Massif (5789 masl) in the eastern Peruvian Andes. The lakes are Laguna Jaico (10.56° S, …
The Effect Of Canopy Organization On The Photosynthesis Of Sphagnum, Brian Solinsky
The Effect Of Canopy Organization On The Photosynthesis Of Sphagnum, Brian Solinsky
Honors Theses
With climate change becoming a greater problem the ability of plants to photosynthesize and sequester carbon becomes more important for us to understand. Sphagnum moss stores more than a third of the world’s soil carbon. Much is understood about the physiology of Sphagnum, but what is generally not understood is the effect of variation in canopy organization in Sphagnum: why are they both rough and smooth? This study examined whether different canopy structures influenced how the canopy uses different angles of light for photosynthesis. The first step was modeling photosynthesis in two simulated structures (rough and smooth) as the angle …
Anti-Nuclear Activism And The Past, Present And Future Of United States Nuclear Energy Policy, Isabel C. Zellweger
Anti-Nuclear Activism And The Past, Present And Future Of United States Nuclear Energy Policy, Isabel C. Zellweger
Honors Theses
Nuclear power has had a long and controversial history leading people to have many different views on the topic. Even though nuclear power does provide the nation with a significant portion of its electricity, many still fear its risks, especially after the events at Fukushima last spring. This thesis explores how public opinion, current events, and anti-nuclear activism have shaped nuclear power in America today. After reviewing the literature on nuclear energy in the United States, I discuss the past and current state of United States nuclear energy policy, and then describe changing American attitudes toward nuclear power over time. …
