climate change in eurasian arctic shelf seas centennial observations of ice cover
p in this book the eminent authors analyse the ice cover variability in the arctic seas during the 20th and early 21st centuries . in the first two chapters they show that multi year changes of the sea ice extent in the arctic seas were formed by linear trends and long term climatic cycles lasting about 10 20 and 60 years . the structure of temporal variability of the western region greenland kara differs significantly from the eastern region seas laptev and chukchi . in the latter region unlike the former area relatively short period cycles up to 10 years predominate . the linear trends can be related to a super secular cycle of climatic changes over about 200 years . the most significant of these cycles lasting 60 years is most pronounced in the western region seas .
