Project Description: 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 camps will be reached by fixed-wing plane on floats, landing in lakes, and they will be set up beside the lakes. Each camp will be occupied for about one week. Fieldwork around the Johnson Bay camp will be carried out on foot, and fieldwork around the Mason Bay camp will use a small boat, in order to visit coastal bluffs in Summer Island, Richards Island and Hadwen Island. Fieldwork will be carried out by clearing slumped sand from coastal bluffs, with spades and trowels, and collecting samples of sand, wood or peat for laboratory analysis. Sample size will be about 5–200 g. Similar research methods from fly camps in these general areas have been used by the principal investigator since 1989. A member of the Tuk HTC will be sought to accompany the party during all of the fieldwork, and will be employed as bear monitor and boat operator. The study will be conducted at the north shore of Liverpool Bay, approximately 2 km southwest of Johnson Bay, and at the Mason Bay area, on northeast Richards Island. The research will be conducted from July 28 to August 11, 2005.
