    I am a geology major with a focus on glaciology and Geomicrobiology. My area of focus revolves around glacial environments and the reactions between them and their constituents (primarily microbial bacteria). I aim to become a research professor focusing on Geomicrobiology at a university after getting a masters and PhD in glaciology/Geomicrobiology. My interests relate to the geospatial sciences in both micro and macro scale as thinking spatially is imperative when relating organisms with their

    Washington’s Trail through Post Glacial Butler, PA In 1753, the future first president of the United States, George Washington, was dispatched to Western Pennsylvania to deliver a message to the French soldiers stationed near Presque Isle. Only twenty-one years old, young Washington traveled north from Fort Duquesne through modern day Butler County. Although aware of the critical and dangerous nature of the mission, it is unlikely that that the young explorer was aware that he was traversing a land

    Introduction Researches on the beginnings of coastal adaptation and exploitation of maritime adaptations have been carried out by John Erlandson and colleagues. There are existing anthropological theories which are over 10, 000 BP but Erlandson believes that the societies of hunter-gather used aquatic resources and among them were popular terrestrial hunter-gatherers (Slaymaker, 2007). This has been challenging since it is difficult to define exactly constitutes of fully maritime culture. There

    The article, Kelp genes reveal effects of subantarctic sea ice during the Last Glacial Maximum, describes an experiment designed to measure the extent of sea ice in the Southern Hemisphere during the Last Glacial Maximum (LGM). Prior to this study, palaeogeographers had had yet to decisively determine the extent of sea ice in the southern hemisphere during the LGM, so this experiment greatly contributed to the progress of the palaeogeographic field. The authors of this article also notably pioneered

    Glaciated Uplands and Glaciated Lowlands Arran is an ideal place to look at when examining the validity of the statement. During the Devensian Glacial, the ice sheet covering Britain reached its furthest extent, totally covering Arran. This helped to shape the landscape. In around 11,000BP the Loch Lomond Readvance occurred. This time Arran was not covered by an ice sheet but its valley glaciers grew. This formed many of the features still clearly seen on the island today. They show fresh

    A most recent inquiry into climatic change during the ice age and it's possibility of reoccurring is the Snowball Earth Hypothesis advanced by Paul Hoffman of Harvard University. Snowball Earth Suggest that before the Ice age, continents ice free at the poles enhanced the reabsorption of carbon dioxide through erosion of silicate minerals, reducing the greenhouse effect making the earth colder until it reached a runaway point. This effect is Hoffman calls albedo, when the atmosphere becomes so cold

    Introduction The global oil and gas demand is rising dramatically and explorations of new oil and gas fields became one of major concern in the world. As a result of this, it has been evaluated that, the arctic region, mostly offshore, holds as much as 25% of the world’s unrecovered reserve of hydrocarbons where much of the reserve is lying under seasonal or year-round sea ice. So, future gas and oil production from the Arctic region may be played a crucial role in gas and oil industry. But any

    No one in the scientific community would argue with the premise that the earth’s climate has changed over the eons of its existence or that it will continue to change. The arguments now revolve around if mankind’s use of the environment has specifically altered our climate. Scientists have described our world as a clump of matter that spun out of the sun to join its journey hurling though cold and empty space. Our spaceship earth would match the moon and have no climate had not molten core continued

    The Greenland ice sheet is the second largest ice mass on Earth and is about one-tenth the volume of the Antarctic ice sheet. It is the only significant ice mass in the Arctic today. [ See Antarctica and Climate Change ; and Ice Sheets .] It is an ice-age relict that overlies a bowl-shaped continent almost completely fringed by coastal mountains. PHYSICAL-GEOGRAPHIC SETTING The ice sheet extends from about 60° to 83°N over a distance of 2,400 km in the North Atlantic Ocean. The ice sheet covers

    Glacial Till The characteristics of glacial till reflect the erosional, transportational and depositional history of the constituent sediment.’ Glacial till is a heterogeneous mixture of rock fragments ranging in size from clay to boulders and is deposited directly from glacial ice without water transport. (Strahler A. H. & Strahler A. N. 1976). Ice sheets deposited in the Pleistocene period may be more than 30 m deep and inevitably the constituents of glacial till will reflect the retreats
