Principal Investigator: Beilman, David W
Licensed Year(s): 2013
Summary: 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...

Principal Investigator: Keigwin, Lloyd D
Licensed Year(s): 2013
Summary: 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 ...

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...

Principal Investigator: Hardy, Francois
Licensed Year(s): 2001
Summary: The research team will be transported from Yellowknife to Eyeburry Lake by fixed wing aircraft. From here, the research team will travel approximately 120 km down the Thelon River by canoe, and study the stratigraphy of sediments on the shoreline. Field camps will be located along the river, and will be for one night only. All human waste will be buried, and all non-burnable garbage will be pack...

Principal Investigator: Retelle, Michael J.
Licensed Year(s): 1992 1991 1990
Summary: The researchers will attempt to reconstruct climate and past environmental conditions through recovery and study of sediment cores from lakes at Taconite Inlet, northern Ellesmere Island. They will also monitor conditions under which the lake sediments are presently accumulating....

Principal Investigator: Morgan, Alan
Licensed Year(s): 1991
Summary: The Researchers will collect sediment samples. Insect fossils will be extracted and analysed. The insect communities recovered will provide an indication of the climatic conditions in the area at the time the sediments were deposited. The age of the sediments will be determined with radiocarbon or other dating methods....

Principal Investigator: Gajewski, Konrad
Licensed Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: The Researcher and his assistant will collect small sediment samples from a series of small un-named lakes on Somerset, Bathurst and Cornwallis Islands. The samples will be analyzed for pollen and other organisms for their studies of past climates and environments....

Principal Investigator: Miller, Raoul
Licensed Year(s): 1990
Summary: Mr. Miller and Mark Abbott will take water samples and cores from the sediment at the bottom of several lakes on Laird and Becher Peninsulas, Baffin Island. The purpose of the sample collection is to find out about past climate of the area and also to see what impacts human activity in the Arctic might have on these lakes....

Principal Investigator: King, Roger H.
Licensed Year(s): 1994 1992 1991 1990 1988
Summary: This is the fourth year that Dr. King and his students will be working in the Truelove Lowland area of Devon Island. They are extracting columns of soil and rock to investigate how the climate has changed since long ago....

Principal Investigator: Stewart, Thomas G.
Licensed Year(s): 1979
Summary: To collect samples of marine and non-marine sediments and to record evidence of driftwood presence in the fiord. The purpose of the study is to create a better understanding of the climate of the area since the last ice age....
