This bachelor thesis is focused on the time series of the sea ice area monthly avarage analysis in five regions in the Southern Hemisphere and in six regions in the Northern Hemisphere in the period 1978 -- 2012. The analysis involves also the sea ice area in the whole Arctica and in the whole Antarctica.

The analysis involves also the sea ice area in the whole Arctica and in the whole Antarctica. The time series were obtained from the Science Research Portal administered by the Goddard Space Flight Center, which comes under NASA. The objective of this thesis is to determine the development of the time series in particular regions and compare them to each other. For this analysis, I am using the basic characteristics of time series and tools for the description of their trend and their seasonal components. Another aim is verification of two following hypotheses. The first hypothesis is that the sea ice area in the whole Arctic region is on the decrease. The second hypothesis is that the sea ice area in the whole Antarctic region is on the decrease. The thesis is divided into two parts, into theoretical and empirical. The theoretical part lays the foundations for the second part, which is practical and refers to the analysis of time series itself. |
