                         global influence on the heat and mass transfer processes. Its 
                         capacity of isolation restricts the mass and energy transfers 
                         between ocean and atmosphere, influences salinity and, by 
                         consequence, de density of the upper layers of the ocean, that can 
                         influence oceanic circulation and formation of deep waters. On the 
                         last decades, Arctic and Antarctic sea ice have presented very 
                         distinct tendencies in relation to variations in Sea Ice Extend. 
                         Arctic Sea Ice is retreating moves very fast , contrasting with 
                         the Antarctic sea ice, that presents a tendency of increase in 
                         almost of of its regions. In this study, variations of the Arctic 
                         and Antarctic sea ice extent were analyzed using satellite-derived 
                         data. The data set used was NOAA Optimum Interpolation SST (Oi 
                         SST), a global one degree latitude and longitude resolution data 
                         set . The results indicate a tendency of increase in the Antarctic 
                         Sea Ice, specially in the Ross and Weddell Seas, and a decrease in 
                         the extent on Bellingshausen and Amundsen Seas. In the years 2006 
                         and 2012, maximums in the Sea Ice extent were observed in 
                         Antarctica. In contrast, Arctic Sea Ice presented a tendency of 
                         decrease and minimum extent records were observed in the years 
                         2007 and 2012. This type of analysis is important because sea ice 
                         acts an important role in the thermal balance of the planet, 
                         restricting the vertical fluxes of heat between ocean and 
                         atmosphere and increasing the albedo, allowing an analysis of the 
                         feedback albedo sea ice mechanism that contributes greatly to the 
                         climatic changes.",
