[Show abstract][Hide abstract] ABSTRACT: Heavy metal escapement associated with ore trucks is known to occur along the DeLong Mountain Regional Transportation System (DMTS) haul road corridor in Cape Krusenstern National Monument, northwest Alaska. Heavy metal concentrations in Hylocomium splendens moss (n =226) were used in geostatistical models to predict the extent and pattern of atmospheric deposition of Cd and Pb on Monument lands. A stratified grid-based sample design was used with more intensive sampling near mine-related activity areas. Spatial predictions were used to produce maps of concentration patterns, and to estimate the total area in 10 moss concentration categories.

[Show abstract][Hide abstract] ABSTRACT: Alaska. The diversity of areas and of their resources is reflected in their designation as national parks, monuments, preserves, and historical parks. These 16 areas represent more than 50 percent of the total acreage the National Park Service administers. The Alaska Region's Resource Management Program directs scientific research and resource management programs in a wide range of biological, physical, and social science disciplines. The National Park Service disseminates reports on high priority, current resource management information, with managerial application, through the Alaska Region's Natural Resource Report Series. Technologies and resource management methods, resource management papers, proceedings of conferences and resource management workshops, and natural resource management plans are also disseminated through this series. Documents in this series usually contain information prepared primarily for internal use by the National Park Service. Mention of trade names or commercial products does not constitute endorsement or recommendation for use by the National Park Service.
