An analysis of one year of surface layer meteorological data from the Arctic pack ice

Creator:: Baumann, Richard James
Abstract:: The thesis describes the properties of surface wind and air temperature time series recorded at three locations on the pack ice of the Beaufort Sea. Time series consisting of sequential one-half hourly means were constructed for a period of approximately a year. A diurnal fluctuation in air temperature is found...

Modeling Arctic melt ponds using a resolved ice model with GCM forcing

Creator:: Collins, Lee E.
Abstract:: The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...

Carbon cycle variability during the last millennium and last deglaciation

Creator:: Bauska, Thomas K.
Abstract:: The exchange of carbon on earth is one of the fundamental processes that sustains life and regulates climate. Since the onset of the Industrial Revolution, the burning of fossil fuels and anthropogenic land conversion have altered the carbon cycle, increasing carbon dioxide in the atmosphere to levels that are unprecedented...

Using reanalysis data to characterize Arctic and Sub-Arctic glaciers

Creator:: Ourada, Quin
Abstract:: The net mass balance fluctuations of Arctic and Sub-Arctic glaciers, north of 47.5° North latitude, are described over a 45-year period from 1957 to 2002 using two parameters derived from a gridded climatology reanalysis. Variability among 185 measured glaciers was represented according to two main components. The first component represents...

Decoding DOM Degradation with Metatranscriptomics : How Do Sunlight and Microbial Communities Interact to Degrade Dissolved Organic Matter in Arctic Freshwaters?

Creator:: Nalven, Sarah G.
Abstract:: Arctic soils are warming, making vast stores of organic carbon available for conversion to CO₂. This could create a positive feedback loop and accelerate global warming, but the processes that convert this carbon into CO₂ are not well understood. We investigated how the combined activities of sunlight and microbes degrade...

Quantitative Metatranscriptomics and Biogeochemical Rate Measurements Reveal Microbial Pathways Driving Carbon and Nitrogen Cycles in an Arctic Lagoon

Creator:: Griffin, Natasha A.
Abstract:: Microbial communities in Arctic coastal lagoons drive biogeochemical cycles at the terrestrial-marine interface and help to determine the fate and form of resources like nitrogen (N) and carbon (C) as they are delivered to the Arctic Ocean. Though rising rates of primary production in the Arctic Ocean are well-characterized, the...

Assessment of exposure and response to atmospherically-derived contaminants in U.S. Arctic freshwater fish

Creator:: Allen-Gil, Susan M.
Abstract:: The Arctic has long been considered to be a pristine environment, far from population centers and pollution sources. The detection of synthetic organochlorine compounds in various elements of the Arctic food web has confirmed the global dispersion of pollutants, particularly of persistent compounds such as organochlorines and heavy metals. Levels...

Modeling and dating glacier fluctuations and their relation to Pacific Ocean climate

Creator:: Anslow, Faron S.
Abstract:: This thesis presents the results of an investigation into the interactions between the present-day South Cascade Glacier and the former Mauna Kea ice cap at short (annual to centennial) and long (millennial and multimillennial) time scales. To quantify the response of South Cascade Glacier to atmospheric conditions, a surface energy...
