Prinsenberg, S.J., I.K. Peterson, J.S. Holladay and L. Lalumiere, 2010. Helicopter-borne sensors monitoring the pack ice properties of Mackenzie Delta: April 2010 Sea Ice Survey. Can Tech. Rep. Hydrogr. Ocean Sci. 267: viii+62pp. This report presents examples of a unique data set that was collected with helicopter-borne sensors during April 2010 over the Mackenzie Delta land-fast and mobile ice cover areas. Helicopter logistic support was provided by the Canadian Helicopter Company in Inuvik, NWT which was used as a base for the entire survey. For the first time a Ground-PenetratingRadar provided snow depths and ice thicknesses of low salinity ice and complemented the Electromagnetic-Laser and Video-Laser data sets to explain the ice and snow properties found in the Mackenzie Delta. In spite of numerous weather delays, the survey completed most of its planned pack ice survey lines and provides a large spatial distribution of data to derive ice and snow statistics and to validate ice signatures seen in RADARSAT-2 and TerraSAR-X SAR imagery. All data, plots, photographs and reports will be available through the DFO Maritimes Region’s “SeaIce” Website: http://www.mar.dfompo.gc.ca/science/ocean/seaice/public.html and its data link on the DFO Maritimes Region’s FTP site: ftp://starfish.mar.dfo-mpo.gc.ca/pub/ocean/seaice/.
