A late Cretaceous and Paleogene arctic paleoclimate record: the sedimentary sequence at Strand Fiord, Axel Heiberg Island, NWT
chercheur principal: Tarduno, John A.
Année(s) de permis: 1993
Résumé: For much of the Earth's history, the arctic has had a mild climate, quite unlike the conditions that now exist. Evidence that supports this past climate are fossil plants and animals (including crocodiles and tortoises) found in the arctic. The Earth's magnetic field has changed over time and these changes are contained in the fossils. This research will try develop a technique to age these fos...

Long-term Stability of Arctic Island "Oases"
chercheur principal: Gajewski, Konrad
Année(s) de permis: 2008 2004 2001 1994 1993 1992 1991 1990
Résumé: This study will investigate the long-term stability of the arctic "oases" of Polar Bear Pass and Hot Weather Creek by the pollen analyses of lake sediment cores. The sediment that accumulates in the bottom of lakes provides a history of the conditions in the lake. The pollen incorporated in the sediment can be interpreted to give an idea of the climate and vegetation for the past several thousand ...
