Glaciology

GG310 OCEANOGRAPHY Evaluate the geological evidence for so-called ‘Snowball Earth’ glacial episodes in the Precambrian and the hypothesis that these episodes were critical in the evolution of complex life. Introduction The importance of this period is that multicellular evolution began to accelerate after the last glacial ended.refbookpage829.The term Snowball Earth refers to the hypothesis that in the distant past, specifically the Cryogenian period (850-630 million years ago), the earth’s…

Until 11,700 years ago our earth had been in the Pleistocene Epoch, incorporating an evolutionary surge that lead to Homo Habilis, who lived from about 2.1 to 1.5 million years ago(2). By the peak of this duration the global temperatures on earth dropped by about 5oC, plunging the entire planet into an ice age, creating vast glaciers miles deep that expanded across limitless amounts of land, locking hordes of water into impenetrable sheets of ice. However, this gave a few species on earth a…

tectonics to geochemistry, and from geophysics to glaciology. Geology has guided my research interests as well. As a college freshman, I was accepted into a research group with Dr. Kevin Furlong to research earthquakes along the Himalayan Fault, along with major earthquakes around the world, such as the Vanuatu (M 7.1 on 10/21/2015), and the Chile earthquake (M7.8 on 9/16/2015). Within the year, my research interest changed to glaciology, based on a glaciology lecture in my geophysics course.…

shows that global warming did not cause Antarctica ice melt loss over a nine year period between 1992 and 2001, during which the continent actually gained more than 110 billion tons of ice every year. The study, which appeared in the Journal of Glaciology, also reported that the amount slowed to 80 billion tons of ice a year between 2003 and 2008, but the gains have not been consistent around the continent. According to the study results, there was a loss in ice in the area of the Antarctic…

From enactment art to the atmospheric, sound art to visual installations, Nuit Blanche is an event that propagates in admiration in numerous cities each year. The exhibit takes place all night, individuals can amble from one side of the city to the other observing, experiencing and even partaking in art expositions which range from secret tunnel vibrational drones, a contraption of metal tubes/containers that generate various reverberations when hit – creating a symphony done by the public, a…

Physical Geography is the part of natural environment such as atmosphere, biosphere, and geosphere. It also involves the geography of places like mountains, plains, prairies , etc. Areas within physical geography can be divided into categories such as these and others. Geomorphology the study of the earth, how it was, and how it continues to be shaped. It helps us to predict future changes. Pedology is the study of soils in the natural environment. Palaeography is the study of preserved…

process is also useful to anthropologists in other studies. According to the internet article, The Solar Origins of Dendrochronolgy, by Matthew Wills (2015), Dendrochronolgy is also valuable to use in the fields climatology, ecology, geomorphology, Glaciology, hydrology, and entomology (para.…

Literary devices have been use in many writings to produce a special effect for the readers. From allusions to metaphors, each and every one of these devices serve a very important purpose. In the novel, Icefields, Thomas Wharton uses many literary devices to make Icefields more captivating for his audience. The use of these devices are mostly subtle but very impactful when discovered. Through the use of these literary devices readers can have a better understanding of the story. Wharton’s use…

Every year I spend half of my summer hiking the Rocky Mountains of Montana with my mom and the other half climbing the Cascade Mountains of Washington State with my dad. I have grown up in two different states because of my parents divorce. However, I don 't have an innate sense of pride for one state but a pride for the two separate and unique mountain ranges that have shaped who I am today. When I am in the free and open space of a forest with the cool summer breeze flowing through my hair and…
