Mid-Pliocene To Early Pleistocene Sea Surface And Land Temperature History Of Nw Australia Based On Organic Geochemical Proxies From Site U1463, Rebecca Smith

Masters Theses

Ocean gateways facilitate water circulation between ocean basins, and therefore directly impact thermohaline circulation and global climate. In order to better predict the effects of future climate change, it is critical to constrain past changes in ocean gateway behavior, and corresponding changes in thermohaline circulation, particularly during analogue periods for modern climate change. The Indonesian Throughflow (ITF) is a primary ocean gateway and vital component of the global conveyor that transports water from the Pacific Ocean into the Indian Ocean, however due to a lack of long and continuous sedimentary records from locations under its influence, changes in ITF behavior …

Spatio-Temporal Variability Of Precipitation And Drought In The State Of Arizona, Usa, Samuel Nimako Nyarkoh

Masters Theses

As a result of climate change, several dry regions continue to get drier as precipitation amounts decline. This decline impact water resources and hinder economic development. Understanding the variability of precipitation and drought through climatic, agricultural and hydrological studies is therefore critical to decision makers and stakeholders in developing proactive measures that promotes economic development.

This study therefore uses dataset from 55 Meteorological stations containing 110-year (1900-2010) monthly precipitation data and a series of spatial and temporal tests to investigate the spatial and temporal patterns of precipitation and drought as well as the effects of local factors such as topography …

Determinants Of Household Water Use In The City Of Kalamazoo, Michigan: The Role Of Climate And Socioeconomic Factors, Danielle Molenaar

Masters Theses

Located in the Great Lakes Watershed, the City of Kalamazoo can be considered “water rich”. Therefore, the area has been absent from water use studies. Water use studies are beneficial in all locations; as they can aid city planners, water resource managers, and utility companies. This study examines how household monthly water use in the City of Kalamazoo is impacted by both climate and socioeconomic variables over the period 2006-2016. Household level data were aggregated into census tracts to obtain monthly tract averages for the eleven-year period. Ordinary least squares regression (OLS) was used to determine which variables impact the …

Interannual Variations Of Snowfall In The Lower Peninsula Of Michigan And Impacts Of Local And Remote Meteorological Conditions, Nirjala Koirala

Masters Theses

Inter-annual variation of snowfall and its relation to climate indices will help clarify and improve the prediction of total snowfall in the Lower Peninsula of Michigan (LPM). This study examines the trend and variability of annual snowfall (November- March) using 8 homogeneous weather stations in the LPM. The statistical relationship between snowfall and air temperature, Sea Surface Temperature (SST), North Atlantic Oscillation (NAO), Pacific Decadal Oscillation (PDO) and Maximum Ice Coverage(MIC) of Lake Michigan is calculated. The long-term trend in the snowfall data set from 1950 to 2015 is removed before any statistical correlation analysis is conducted. My analysis suggests …

Impact Of Temperature Increase On Freshwater Fish Species: Energetics And Muscle Mechanics Of Two Centrarchids, Israt Jahan

Masters Theses

Fishes have evolved physiologically to live within a specific range of environmental variation and existence outside of that range can be stressful or fatal. These ranges can coincide for fishes that evolved in similar habitats. This study investigates physiological processes limiting thermal tolerance, specifically how changes in water temperature affect the swimming energetics and muscle mechanics in largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus). I focused on the impact of temperature change at the muscle level in these two species and the capacity to adapt to rapid changes in the environment. Fish were housed at …
