Water and leaf wax isotopes in permafrost
Principal Investigator: Porter, Trevor
Licensed Year(s): 2014
Summary: The primary objectives of this research project are to collect frozen core samples from the top of permafrost and soil from the active layer. Boreal sites will be targeted. The stable isotope compositions of ice and leaf waxes from the samples will be measured. Samples collected from NWT will be added to a much larger Yukon dataset, and the relations between regional climate and the proxies will b...

Mio-Pliocene Plant DNA Barcoding
Principal Investigator: Spencer, Lee A
Licensed Year(s): 2009
Summary: This licence has being issued for the scientific research application No.1072. The researchers will collect plant fossils from the Miocene Ballast Brook and Pliocene Beaufort Formations (Ballast Brook River), Banks Island. They will transport the specimens to Southern Adventist University, Collegedale, Tennessee, USA, for DNA processing and analysis. A final report will be submitted to Aurora...

Postglacial Paleoclimatology of the central and western Arctic Islands
Principal Investigator: Gajewski, Konrad
Licensed Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: The goal of this study is to collect lake sediment cores from shallow lakes to quantify the impact of past climate change on the vegetation and lakes of the area. Sediment cores from the bottom of 2 lakes in the region will be collected. A 10 day camp of 3 people will be set up at 71°43'12"N, 122°02'31"W. Transportation will be by Twin Otter to the camp, and by walking to the lakes. No gas powe...

Early Land Plants From 400-Million-Year-Old Rocks of Bathurst Island.
Principal Investigator: Basinger, James F.
Licensed Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: The oldest known land plants are found in rocks of about 400 million years old. Rocks of this age are rarely found in North America. Recently, fossils from this critical interval have been found on Bathurst Island (preliminary work in 1993). The researchers will explore other possisible sites on central Bathurst Island. The fossils recovered will contribute to the understanding of early plant ...

A late Cretaceous and Paleogene arctic paleoclimate record: the sedimentary sequence at Strand Fiord, Axel Heiberg Island, NWT
Principal Investigator: Tarduno, John A.
Licensed Year(s): 1993
Summary: 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...

Treeline plant population response to postglacial climatic change in North Central Canada.
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1987
Summary: To use fossil pollen and plant macrofossils from small lakes to reconstruct the response of plant populations in the treeline zone to climatic change. Modern pollen surface samples from small lakes in the treeline zone will be collected to aoid in the interpretation of the fossil pollen samples. The study area will include the boreal forest, forest-tundra and tundra zones near Yellowknife (115 W...

Licence #5120
Principal Investigator: Basinger, James F.
Licensed Year(s): 1985
Summary: To collect additional fossil plants and to better determine stratigraphy in the vicinity....

Licence #5012
Principal Investigator: Basinger, James F.
Licensed Year(s): 1985
Summary: To take fossil plant collections for the understanding and interpretation of plant distribution and evolution in the early Tertiary of western and northern Canada....

Licence #4066
Principal Investigator: Jacobs, John D.
Licensed Year(s): 1984
Summary: To carry out micrometeoroligical measurements, mapping, and collection of lake sediments, soils, and plants for analysis. The object is to describe the sequence of post-glacial climate, vegetation, and environmental change....

Licence #2776
Principal Investigator: Short, Susan K.
Licensed Year(s): 1982
Summary: To analyze changes in the modern and fossil pollen assemblages of the Central Canadian Arctic through the collection and analysis of modern moss samples and peat and lake sections....
