Impacts of Ozone Depletion in Relation to Antarctic Ecology Kimberly Joy T. Keck I. Introduction The ozone layer is a belt of ozone gas in the stratosphere, 6.2 up to 31 miles above the lithosphere. This layer serves as a barrier from the harmful ultraviolet- B radiations emitted by the sun (National Geographic, 2010). Ozone layer is composed of continuously interaction of ozone, a molecule that is composed of three oxygen atom molecules. Cornu and Hatley first described the unique role of these molecules in absorption of ultraviolet light. In addition, the ozone layer was first discovered in 1913 by Charles Fabry and Henry Buisson (Solomon, 1999) however, the properties was first described by Dobson who invented a simple spectrophotometer…show more content…
In today’s condition, the earth is suffering a drastic depletion of this layer due to excessive release of pollutants containing chlorine and bromine gasses of chlorofluorocarbons (CFCs) and halons (Solomon, 1999). Recent studies states that these deteriorations let extra UV-B radiation to reach the earth’s surface that inhibits the reproduction of phytoplankton, organisms that make up the base of food chain. They also documented the declining reproductive rates if young fish, shrimp, frogs and crabs exposed to excessive UV-B (National Geographic,…show more content…
This region is the s southernmost continent of the Earth, surrounding the South Pole at approximately 66.33° south of the Equator. The continent is not centred over the South Pole, and instead, the greater portion of Antarctica lies within the Eastern Hemisphere. The West Antarctic Ice Sheet of this region generally occupies the area of land within the Western Hemisphere and is lined by Weddell Sea and Ross Sea on either side. The Transantarctic Mountains that extends across the continent forms the physical boundary distinguishing the East Antarctica from West Antarctica respectively.. Most part of Antarctica is on south of the Antarctic Circle, except parts of the East Antarctic coastline and the Antarctic Peninsula which extends northwards from West Antarctica to about 63°S.
