Environmental Change in the Western Canadian Arctic Islands
Principal Investigator: England, John H
Licenced Year(s): 2012 2010 2009 2008 2007 2006 2005 2004 2003 2002
Summary: 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...


Chemical Evolution of a Hypersaline High Arctic Coastal Lake
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2010 2009
Summary: This licence is being issued for the scientific research application no. 1013. The goal of this research is to distinguish the chemical and physical processes acting on different lakes on Melville Island in order to understand how the systems have developed through time. Of particular interest is the mechanism to explain how the lakes became salty after the last glaciation. Shellabear Lake ...


Surficial Mapping of Tuktut Nogait National Park
Principal Investigator: Veillette, Jean
Licenced Year(s): 2001
Summary: Field work will consist of helicopter traverses run from two base camps, with stops at points of interest previously identified from air photos, and detailed traverses conducted from fly camps lasting from 4-6 days. Fly camps will be run by a two-man crew, positioned by helicopter, who will operate up to 10-15 km from the camp. Most field observations will be directed at identifying and counting ...


Banded Iron Formations and "Snow-Ball Earth" Events
Principal Investigator: Hoffman, Paul
Licenced Year(s): 2001
Summary: The research team will be based out of Norman Wells, and establish a series of fly camps in the research area between 1 July and 10 August. Travel to fly camps will be by helicopter; travel in the field will be on foot. Fly 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. Stratigraphic sections...


Proterozoic Ice Ages in Northwestern Canada
Principal Investigator: Narbonne, Guy
Licenced Year(s): 2001 1999 1998 1996 1994 1992 1991 1989 1988
Summary: The research team will be flown from Norman Wells to the base camp near Shale Lake by helicopter. The camp will consist of one sleeping tent and one cooking tent. The research team will walk to several rock sections with 3 km of the base camp. Data collection will consist of measuring rocks with a ruler, taking photographs, and collecting up to 50 small (fist-sized) pieces with a hammer. The r...


Past glaciation, landscape evolution and climatic change in the Canadian High Arctic
Principal Investigator: England, John H
Licenced Year(s): 1993 1990
Summary: The effects of glaciation on the arctic landscape remain uncertain and much more mapping and field studies remain to be done. Although it is commonly assumed that global warming will lead to the melting of glaciers, this view ignores the more important role that snowfall plays in the growth of glaciers (i.e., warmer climate leads to increased snowfall and a growth in glaciers). This study will e...


Late Quaternary history and paleoenvironmental change in the Lake Hazen Basin on Ellesmere Island
Principal Investigator: Smith, Rod
Licenced Year(s): 1993 1992
Summary: It is believed that during the last ice-age on northern Ellesmere Island, Lake Hazen was `pushed' further south as a result of the presence of glaciers. The researchers are investigating the Lake Hazen Basin area to determine the nature of this ancient lake. Sediment samples will be taken from both Lake Hazen as well as the surrounding area to study the past environment and organisms (now fossils...


Late Quaternary glacial and climate history on Baffin Island, NWT
Principal Investigator: Miller, Gifford H.
Licenced Year(s): 1994 1993 1991 1990 1989 1987
Summary: The arctic has an effect on the climate experienced in the rest of the world. We are attempting to understand how climate and the growth (movements) of glaciers influence each other, both in the present and during the last 20,000 years. We will be taking samples of sediments from the bottoms of lakes as these sediments contain information about changes in climate....


Preglacial channel and sediment-fill of the ancestral Mackenzie River Valley between Wrigley and Fort Good Hope, NWT
Principal Investigator: Smith, Derald
Licenced Year(s): 1993
Summary: The Mackenzie River Valley, from Wrigley to Fort Good Hope, will be surveyed in order to document the nature of the river prior to the last glaciation. Sediments will be sampled in order to determine their age (using radiocarbon dating techniques). Field work will take place along the Mackenzie River between Wrigley and the mouth of the Redstone River, in the lower section of Gt. Bear River, and...


The Quaternary history of Scoresby Bay, Ellesmere Island
Principal Investigator: Gualtieri, Lyn
Licenced Year(s): 1993
Summary: The purpose of this research is to determine the amount of ice coverage during the last glaciation by investigating the landforms that occur today. I will also record the change in sea-level and the rise in the land as the glaciers receded. Evidence for the movement of glaciers onto eastern Ellesmere Island from Greenland will be collected. The data collected in this field season will contribut...
