Anthropogenic Influences And Meteorological Effects: How They Are Changing The Sand Beaches In Southern Maine, Heather W. Heinze
Anthropogenic Influences And Meteorological Effects: How They Are Changing The Sand Beaches In Southern Maine, Heather W. Heinze
Electronic Theses and Dissertations
Although sand beaches in southern Maine comprise only a small segment of the coastline, they are economically important to the state. From September 1999-March 2001, volunteers made monthly topographic profiles along nine beaches in southern Maine to monitor changes. The volunteers used the Emery Method of beach profiling to take simultaneous measurements at spring low tide. The beaches are significantly different with respect to physiography, incident wave energy and direction, available sediment supply and extent of development. An average of the profiles for each category demonstrates that the undeveloped beaches experienced regular seasonal fluctuations and a consistent berm elevation from …

Can A Little Ice Age Climate Signal Be Detected In The Southern Alps Of New Zealand?, Jessica L. Black
Electronic Theses and Dissertations
The Little Ice Age (LIA) was a late Holocene interval of climate cooling registered in the North Atlantic region by expansion of alpine glaciers and sea ice (Grove, 1988). Here the LIA includes an early phase from about AD 1280 to AD 1390, along with a main phase from about AD 1556 to AD 1860, followed by warming and ice retreat (Holzhauser and Zumbiihl, 1999a). It has recently been demonstrated from records of North Atlantic ice-rafted debris that the LIA is the latest cooling episode in a pervasive 1500-year cycle of the climate system that may lie at the heart …
Weathering Crust Processes On Melting Glacier Ice (Alberta, Canada), Corinne Joanne Schuster
Weathering Crust Processes On Melting Glacier Ice (Alberta, Canada), Corinne Joanne Schuster
Theses and Dissertations (Comprehensive)
This thesis examines the relationship between the energy balance and hydrology of a glacier at the ice surface interface during the melt season. Experimental sub-catchments were established on the ablation area of the Peyto Glacier, Alberta, Canada, during the summers of 1994, 1995 and 1997. These sub-catchments were equipped with meteorological and hydrological instrumentation to examine relationships in the surface layer. Specifically, the development of a phenomenon known as the weathering crust is followed by examining the ratio between potential surface lowering (calculated from energy available for melt) and actual surface lowering (as measured in the field). This enables an …
