The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...

Here is the project summary from the (U.S.) National Science Foundation proposal that led to this expedition:
The research team propose a three-year project to investigate the origin of the Younger Dryas cooling that began about 13,000 years ago. For decades this cold event has been associated with sea ice in the Arctic and North Atlantic Oceans, and the storage and release of fresh water from ...

In the previous year, research work were started on some of the new occurrences of 2.9 - 2.6 Ga old banded iron formations in the NWT. This opened an exceptional opportunity to study ocean chemistry directly preceding the Great Oxidization Event (GOE). In this regard, the research group has been engaged with the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studi...
Principal Investigator:Patterson, R. Tim Licenced Year(s):
Through analysis of sediment/water interface samples, freeze cores, and dendrochronology the researchers intend to:
i) develop a comprehensive climatic history along a 2° latitudinal gradient in the central NT, variously based on an analysis of freeze cores from lakes along the route of the Tibbitt to Contwoyto Winter Road (TCWR);
ii) determine the relationship between modern lake catchments an...

The objectives of this research are: 1) to determine the status of permafrost landforms. Since 1990, automated microclimate stations powered by solar cells have been operated in the study area. One station is located at each of five permafrost landforms called palsas (low peat covered mounds with permafrost cores). The stations keep a record of permafrost and near-surface temperatures. Depth of...

This licence is being issued for the scientific research application No.1284.
The aim is to understand and reconstruct the extent and dynamics of past glaciers, past climates and ongoing sea level change, including submergence, on Banks Island, through geological mapping and the dating of sea shells, sediment and boulders. The objective is to determine how the environment of Banks Island has ev...
Principal Investigator:Murton, Julian B Licenced Year(s):
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...
Principal Investigator:Gajewski, Konrad Licenced Year(s):
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...
Principal Investigator:Outridge, Peter M Licenced Year(s):
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...

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...
