Mackenzie River Delta Large Wood Survey, Canada, 2019

Data are available at: https://arcticdata.io/data/10.18739/A2RV0D23X This dataset contains ground, aerial, and drone imagery of the Mackenzie River Delta from the period August 16-September 6, 2019. The imagery show large wood deposits dispersed around the delta, and the purpose of this project was to survey large wood deposits (their extent, thickness, porosity, wood diameters, and character) to convert large wood volume into carbon storage. The dataset also contains four types of spreadsheets. The first, "MackenzieDelta2019_SiteInformation.csv" is a table with the region of the site (East Delta, West Delta, Mackenzie River, East Coast), the site name, its gps location, the site porosity and thickness, and any notes. The next set of spreadsheets starting with the region (INUVIK = East Delta; AKLAVIK = West Delta; RIVERS = Mackenzie River; COAST= East Coast) contains individual sheets with site specific data for each site visited (consisting of gps location, large wood diameter transect measurements, estimate of deposit porosity, measurement of deposit thickness, descriptions of large wood samples collected for radiocarbon analysis, and description of cores collected for tree ring counts of standing trees). The last sheets in these datasets contains summary data for wood diameters, radiocarbon samples, and core information. The next dataset, "MackenzieDelta_2019_WoodRadiocarbon" provides the results of the wood radiocarbon analyses, and shows the site name, location, and notes, and radiocarbon measurements. The last dataset, "WoodCarbonCalculations", provides the calculations converting wood extent to carbon weight. These wood extents were found based on remote sensing of very high resolution satellite imagery. The scripts for classifying and analyzing these wood deposits are also uploaded as Matlab codes.
