This human population is the biggest contrast between the two poles,the Arctic has been inhabited by people for many thousands of years whereas the Antarctic has never had any permanent residents. There are many groups of Arctic peoples such as the Inuit, Chukchi, Sami, Yupik, Buryat and Inupi...
These include subtropical North Atlantic central waters (NACW), with low δ15Nnitrate from regional N2 fixation87, and Southern Ocean mode water (SAMW) and Antarctic intermediate water, which have higher nitrate δ15N due to partial nitrate consumption in the surface Southern Ocean86. The ...
The effects of climatic changes are particularly pronounced at these ends of the Earth and have already attracted worldwide attention and concern. Many recent articles related to the International Polar Year underscore the importance of even basic mapping of the Arctic and Antarctic....
(MAP), an inorganic fertilizer that stimulated the biodegradation process in Arctic soils [20], and S-200 Oilgone (formerly referred to as Inipol EAP22), an oleophilic fertilizer that was found to promote biodegradation on shorelines following the Exxon Valdez oil spill [27]. Surface washing...
The Arctic Ocean has experienced significant sea ice loss over recent decades, shifting towards a thinner and more mobile seasonal ice regime. However, the impacts of these transformations on the upper ocean dynamics of the biologically productive Pacifi

Chemical loss of Arctic ozone due to anthropogenic halogens is driven by temperature, with more loss occurring during cold winters favourable for formation of polar stratospheric clouds (PSCs). We show that a positive, statistically significant rise in t
