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: Miller, Gifford H.
Licensed Year(s): 1994 1993 1991 1990 1989 1987
Summary: The researchers will obtain sediments from lakes near Cape Dyer to document past climatic conditions. Vegetation and lake water chemistry data will also be collected in order to collect information about the current environment: this data can be compared to historic data. Finally, the inner Frobisher Bay area will be surveyed for data about past sea levels and glacial landforms. This research w...

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...

Principal Investigator: Jacobs, John D.
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: This research, begun in 1985, involves measuring climate data such as air and ground temperature, relative humidity, wind speed and direction, solar radiation, precipitation and snow depth. Automatic data collecting stations have been set up to measure these data. The purpose of this research is to document a more accurate picture of the region's climate, to obtain information about the past cli...

Principal Investigator: Marino, Bruno D.
Licensed Year(s): 1992
Summary: The researcher will sample plants and shells containing records of the stable isotopic composition of the constituents in the environment that are used for growth. The natural abundance of the stable isotopes of carbon in atmospheric CO2 and in dissolved groundwater as well as the hydrogen and oxygen isotopes in water can be related to climatic factors. Thus, these isotope ratios in shells and p...

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: Gajewski, Konrad
Licensed Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: 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 ...

Principal Investigator: Koerner, Roy M
Licensed Year(s): 1995 1992 1991
Summary: The Researcher and his team will continue to gather information to understand the past climate in the high Arctic. They will also determine the present climatic trends and pollution levels in the snow....

Principal Investigator: Bradley, Raymond S.
Licensed Year(s): 1981
Summary: To undertake studes of ancient climates (paleoclimatology) and geology. Samples will be collected for further lab analysis....

Principal Investigator: England, John H
Licensed Year(s): 1978
Summary: A collection of field data by instruments and taking rock samples to provide information on climate fluctuations in the past....
