Remote-sensing Resources for Monitoring Glacier Fluctuations on Axel Heiberg Island
We document the abundant resources available for the photographic reconstruction of glacier terminus positions in the Canadian High Arctic, with particular reference to Axel Heiberg Island. Early terrestrial photographs may yet be discovered in the archives of explorers, but systematic photography of the High Arctic began with aerial coverage by the U.S. Air Force’s Operation Polaris in the ear...
متن کاملTaxonomic Composition, Paleoecology and Biostratigraphy of Late Cretaceous Diatoms from Devon Island, Nunavut, Canadian High Arctic
Diatoms are the most diverse group of algae, playing a major role in global carbon and silicon cycles (Kidder and Erwin, 2001; Armbrust, 2009) and inhabiting virtually any environment that provides moisture and sunlight (Mann, 1999). Thus, they offer important information to help reconstruct paleoen-vironments and clarify stratigraphic relationships. Their strati-graphic range extends down at l...
متن کاملEocene Meridional Weather Patterns Reflected in the Oxygen Isotopes of Arctic Fossil Wood
The spectacularly preserved Metasequoia wood excavated from the Fossil Forest site of Axel Heiberg Island (Canadian High Arctic) provides a unique window into the δ18O value of Eocene meteoric water via the analysis of fossil cellulose. Seventeen fossilized Metasequoia individuals yielded cellulose with δ18O (Vienna standard mean ocean water [VSMOW]) values ranging from 17.1‰ to 21.4‰ and with ...

15 صفحه اولNew vascular plant records for the Canadian Arctic Archipelago
The Canadian Arctic Archipelago is a vast region of approximately 1,420,000 km(2), with a flora characterized by low species diversity, low endemicity, and little influence by alien species. New records of vascular plant species are documented here based on recent fieldwork on Victoria and Baffin Islands; additional records based on recent literature sources are mentioned. This paper serves as ...
