AbstractA watershed outline map, a bathymetric map, and water related statistics of the Cape Dorset water supply reservoirs where produced following field work performed during the summer of 2010 by researchers from Canada Centre for Remote Sensing, and personnel from the Department of Community and Government Services and staff from the Nunavut Research Institute. One objective of this initiative was to develop the technology for Nunavut scientists and to transfer the methodologies in communities where drinking water supply is at risk due to a declining supply and a changing climate. Since 2007, with support from Indian and Northern Affairs Canada (INAC), a small team of scientists from the Canada Centre for Remote Sensing were involved in a project to help characterize the water supply of Nunavut communities. This is a complex task involving the delineation of watersheds and estimation of the water volume of the supply lake for the community. To estimate this water volume, a bathymetric map is produced based on field surveys using a depth sounder equipped with a GPS. CCRS developed a low cost and easy to use technique to enable such depth surveys to be rapidly carried out. The technology transfer aspect of the activity is aimed to allow Nunavut professionals to produce lake depth maps with low cost and easy to use tools and software. During the course of this project, these initiatives allowed researchers, engineers, managers, planners and technical personnel to perform lake and watershed surveys of the communities of Iqaluit, Clyde River, Arviat, Whale Cove, Rankin Inlet, Pond Inlet and Cape Dorset. This document describes the digital datasets acquired for Cape Dorset and distributed to the Department of Community and Government Services, the Nunavut Research Institute, and the Department of Indian and Northern Affairs. The enclosed datasets were produced under the ''Enhancing Resilience in a Changing Climate Program'' of the Earth Sciences Sector, Natural Resources Canada. Several large format image maps were printed and distributed to the organisations identified above, and were also presented at several workshops.
