متن کاملHeterotrophic microbial colonization of the interior of impact-shocked rocks from Haughton impact structure, Devon Island, Nunavut, Canadian High Arctic
The polar desert is one of the most extreme environments on Earth. Endolithic organisms can escape or mitigate the hazards of the polar desert by using the resources available in the interior of rocks. We examined endolithic communities within crystalline rocks that have undergone shock metamorphism as a result of an asteroid or comet impact. Specifically, we present a characterization of the h...

متن کاملAtmospheric deposition of current use pesticides in the Arctic: snow core records from the Devon Island Ice Cap, Nunavut, Canada.
Current use pesticides (CUPs) have been detected in the Arctic, even though there are no direct sources and their long range atmospheric transport potential is generally lower than that of legacy pesticides. Data on the deposition of CUPs in the Arctic are required to assess the impact of their global usage and emission. In this study, selected CUPs were measured in the layers of a snow pit sam...
متن کاملUV-VIS-NIR REFLECTANCE SPECTRA OF SHOCKED CARBONATES FROM THE HAUGHTON IMPACT STRUCTURE, DEVON ISLAND, CANADA: 0.35 – 2.5 μm; IMPLICATIONS FOR CARBONATE IDENTIFICATION ON MARS
Introduction: The identification of carbonates on Mars has remained tentative until very recently [e.g., 1-4, 5, 6]. Given that carbonates are present at or near the surface of Mars and appear to be stable in the present Martian atmosphere, it begs the question, why have we only just found them [7]? Is it because they are simply being masked by overlying material or are there other factors that...
