Sulfur in the permafrost environment
Principal Investigator: Murton, Julian B
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5887. The purpose of the fieldwork is to determine the sulfur isotope signature of environmental conditions (superficial deposits, soil, water, vegetation) associated with relatively stable permafrost conditions compared to permafrost thaw conditions Samples of soil (100-200 g), vegetation (<500 g), water (<1 L) and ice...


PALEO-THAW: Unlocking records of past permafrost thaw through isotopes of fossil bones
Principal Investigator: Murton, Julian B
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5255. The main objective of the project is to establish the causes of the major changes in sulphur isotopes recorded in fossil bones of mammals at the end of the ice age. To achieve this, the research team will test the working hypothesis that major changes in fossil bone collagen sulphur are linked to changing biogeochemic...


Carbon in permafrost soils
Principal Investigator: Murton, Julian B
Licensed Year(s): 2019
Summary: The objective of the fieldwork is to collect soil samples from the active layer and near-surface permafrost. Twelve samples will be collected from coastal bluffs at Crumbling Point, and six samples from river banks beside East Channel. Soil profiles 1-2 m deep and naturally exposed by coastal, lake or river erosion will be cleared of slumped soil by spade, and described and recorded. At each si...


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...


Sand-wedge development, Tuktoyaktuk Coastlands
Principal Investigator: Murton, Julian B
Licensed Year(s): 2005 2001
Summary: The objectives of this research are to: describe upward growing and downward growing sand wedges; identify the relationships between wind caused sedimentation, deflation and thermal contraction cracking; and, collect samples of sand from wedges and their host material in order to estimate rates of wedge growth. The fieldwork will be based at two small fly camps at Johnson Bay and Mason Bay. The...


The origin of deformed massive ice, Pleistocene Mackenzie Delta, Western Canadian Arctic
Principal Investigator: Murton, Julian B
Licensed Year(s): 1999 1998
Summary: The main objective of the proposed research is to establish the origin of massive bodies of underground ice at two key massive-ice localities in the Mackenzie Delta area: i) Cliff Point, Liverpool Bay and (ii) near Eskimo Lakes. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and chemistry of the ice and adjacent sediments. The research...
