Cultural heritage or environmental hazard? The South Georgia whaling stations contain important historical information, but also ...

... Biogenic halocarbons and ozone-depletion A group from Chalmers University of Technology in Gothenburg studied the natural production of various halocarbons. Halocarbons are small organic molecules that contain halogen atoms, many of which ...

... of IPY 2007–2008, with participants from six countries. The aim of the project is to explain the development of natural resource exploitation in the polar areas from the 17th century until today, and ensuing consequences for the ...

... any conclusions with respect to a putative connection of the releases to recent warming in the region. In fact, natural thawing mechanisms such as geothermal heat and the 7 000 years of slow warming from the overlying seawater are likely to ...

... of past human activity in Vindelfjällen. Of specific interest to the archaeologists is the way humans used the natural resources found in the alpine environment. One of the study sites is Lake Luspasjaure. Our objective is to provide a ...

... constitutes a major element of uncertainty in climate science. In the summer, Arctic cloud formation occurs under natural pristine conditions with very little impact from man-made pollution. Our understanding of how this system functions ...

... to learn about wild legumes that may, in the future, become domesticated or incorporated into various agricultural systems. Learning about N2-fixing plants in Kamchatka gives a unique opportunity to gain information about legumes that ...

... light on the origin and age of the aerosol particles and to assist in assessing the degree of contribution from natural and anthropogenic sources, as well as local and long-range transported aerosol. Data analysis is currently in progress, ...
