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...

Summary: The objective of this project is to continue an ongoing long-term monitoring of permafrost temperatures on Banks Island and Mould Bay. At these sites the research team have lost remote (satellite) communication and need to make repairs to continue receiving data. The research team are currently monitoring active layer and permafrost temperatures, active layer soil moisture, air temperature, and...

Summary: The aim of the proposed project is to develop, parameterize and evaluate a detailed process-based model of vegetation soil- permafrost interactions using data collected through directed field campaigns in the discontinuous and sporadic permafrost zones of western Canada. The research team will (i) elucidate the role of plant biodiversity in controlling permafrost status in contrasting ecosystems w...

Summary: This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...

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...

Summary: Soil samples will be taken from representative sites in order to complete soil reclamation suitability assessment. Surficial sediments and soils will be described at each pit. In addition, notes will be taken on vegetation, drainage and terrain features, etc. A permafrost survey will consist of drilling shallow holes (<3 m) to determine permafrost conditions. Shallow permafrost drilling will be...

Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...

Summary: This project’s objective is to take multiple, small .25kg samples of the active layer of permafrost in areas where patterned ground and thermokarst are present. The data gained will help the researchers in their efforts to understand possible cold climate processes in the northern hemisphere of Mars. The researchers intend to visit areas in the vicinity of Inuvik and Tuktoyaktuk where polygonal...

Principal Investigator: Menounos, Brian p

Summary: The various objectives of the study are: to refine the previously compiled landslide inventory map with field checking, to identify causal mechanisms to slope instability (such as bedrock or surficial material type, aspect, elevation, glacial history, and permafrost distribution), to identify frequency of landslide types, to examine landscape patterns in the Nahanni karst area to establish relatio...

Summary: The objective of this research is to determine the spatial correlation between surface properties and active-layer thickness. Six sites have been established across the treeline, between Inuvik and Swimming Point. At each site, shallow temperature cables are installed in the active-layer and near-surface permafrost and air temperatures are monitored by data logger. During this project, the res...
