Ice age

Geography and L. M. Sommers, author of “Michigan: A Geography”, “Of all the glacial landforms, moraines best tell the tale of the retreat of the ice from the surface of Michigan. They mark the lines of halt and with their accompanying till plains, the lines of retreat. They reveal the halting retreats and slight readvances of the glacier; they show us where the ice held its position for thousands of years. Each glacial lobe built up its own set of moraines which can be mapped and more or less…

In the article, “Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history,” Robert Mulvaney and several scientists discussed the climate history of the Antarctic Peninsula and its relationship to the collapsing ice shelves. They observed that the ice shelves were collapsing which allowed the glaciers to drain ice at a faster rate. The ice shelves that collapsed were at the Antarctic Peninsula which has had the most rapid warming over the past 50 years. Mulvaney and…

My body heat was melting the ice below me. I continued to listen to the conversation around me which had changed subjects. I was not able to make out what it was they were talking about. I was more focused on the fact that I was slowly descending into the ground. I was terrified of…

I value winter for not only its activities, snow days, or cheering fires, but above all for its simple, natural beauty. I stop in my step, mesmerized by the painted canvas around me. I feel a tingle inside me as I take in my surroundings. There is the perfect mix of blues, greys and whites as I gaze into the sky amongst the fluffy grey clouds. Amongst this painting in the sky, rings of yellow and pale orange create a precise flickering circle. The rings cast a dim glimmer through the colours of…

It was a typical morning in Park City, Utah. Wil Cruz woke up to the sound of his alarm, at 5:30 a.m. and immediately looked out his window. Fresh snow had fallen overnight, about a foot or so, and icicles hung from the lip of his roof that almost reached the base of his house. He got out under the layers of blankets spread around his bed, and went to watch the weather channel. His best friend Jake was already watching, waiting anxiously for the report. “It’s another great day here in Park City…

The wind whipped bitterly by and I pulled up the fabric on my face, looking forward at the ski track in front of me. I knew the race ahead was important, but all I was concerned about in that moment was how frigid my legs felt. He turned around and I jumped, ever so slightly, because when his face had been revealed, I could see the stark horror of the burns on his face. I was talking on the phone with my sister who was on a cruise to the Bahamas, when unexpectedly a loud HONK interrupted our…

As it can be seen in the previous figure, the Bubble Column PBR is a simple conceptual design. The figure simply illustrates the basic flow in the column. The gas enters the bottom of the column through a diffuser causing the gas to break into thousands of small bubbles making it easier for the algae to absorb the carbon dioxide in the gas. Once the algae have consumed as much carbon dioxide as it can, it releases oxygen in the form of gas, which leaves the column through the opening in the…
