Quaternary History of the Summer Island area, Tuktoyaktuk Coastlands
Principal Investigator: Murton, Julian B
Licensed Year(s): 2008
Summary: The objective this geological research is to reconstruct climate and environmental history of Richards Island before the last ice age using sediment and peat samples. Fieldwork around the Mason Bay camp will be carried out on foot and a small boat along the coastal bluffs in Summer Island, Richards Island and Hadwen Island. Fieldwork will be carried out by clearing slumped sand from coastal bluff...

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...

Lithogenic elements and isotopes in peat cores as markers of Holocene climate changes in the Mackenzie River valley
Principal Investigator: Outridge, Peter M
Licensed Year(s): 2007
Summary: The objective of this research is to reconstruct climate change information as well as recent industrial mercury and lead pollution histories for Inuvik and the lower Mackenzie River valley. To determine the above, a core sample of peat will be taken from a peat bog located near Inuvik, and analyzed for elements and dusts deposited from the air over the last 7,000 years. The site will be a...

Paleohydrology and paleoecology of the Slave River Delta
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2007 2006 2005 2004 2003 2002
Summary: This research program focuses on high-resolution reconstruction of past hydrology, ecology and climate of the Peace-Athabasca (PAD) and Slave River deltas (SRD) from natural archives, including lake sediments and tree rings, supported by comprehensive field-based studies of modern hydrology, limnology and aquatic ecology. The PAD and SRD have broad ecological and cultural significance and are ecos...

Past climate change and carbon cycle in the Arctic region
Principal Investigator: Takizawa, Takatoshi
Licensed Year(s): 2006
Summary: During the last glacial maximum (LGM), the sea level was lowered by ~125m. After the LGM, the area of Bering, Chukchi, and Beaufort Seas expanded dramatically, in association with the rapid raising of the sea level due to the collapse of the continental glacier, and the nutrient rich Pacific water stream into Chukchi Sea had become stronger than that of during the LGM. The abrupt rise of sea level...

Dendrochronological Field Invesitigations at the Northern North American Treeline
Principal Investigator: D'Arrigo, Rosanne
Licensed Year(s): 2004
Summary: The overall goal of the project is to develop tree-ring records from old growth trees at northern treeline locations in Canada and Alaska. This information is used to reconstruct Arctic and Northern Hemisphere temperatures over the past several centuries...

Past Climate of Ancient Forests on Banks Island
Principal Investigator: Johnson, Arthur
Licensed Year(s): 2005 2003
Summary: Fossil wood in coal deposits at two sites on Banks Island will be collected and used to estimate the climate regime under which the ancient plants of Banks Island grew. This information may provide insight into how the present day Arctic will respond to...

Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2002
Summary: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...

Late Quaternary hydrological and climatic history of the lower MacKenzie River basin
Principal Investigator: Beierle, Brandon
Licensed Year(s): 2002
Summary: The research team will obtain sediment cores from a series of lakes near Reindeer Station and Inuvik for the purpose of reconstructing the hydrological, climatological and geomorphic history of the lower Mackenzie River basin. The research will require fieldwork between 15 April and 25 April. Research will involve the development of a high-resolution paleoenvironmental record based on lake sedime...

Role of Climate and Sea Change on Early Cambrian Evolution
Principal Investigator: Pope, Michael
Licensed Year(s): 2003 2002 2001
Summary: The research team will fly to Norman Wells by commercial airline, and then travel to the field by helicopter or Twin Otter. Travel in the field will be by canoe, or on foot. Field camps will be low impact, and will be occupied for less than 14 days. All human waste will be buried, and all non-burnable garbage will be packed out. The research team will measure, describe and sample the Early Camb...
