In June, 1998, the Department of Health and Social Services released Shaping Our Future, A Strategic Plan for Health and Wellness described by ASTIS record 66579]. This plan builds on the Med-Emerg plan which was released in 1997 described by ASTIS record 66596]. Shaping Our Future presents 22 strategic directions and some 90 tasks. The Med-Emerg report offered 49 recommendations. Three years earlier, the Special Committee on Health and Social Services had released its final report with 39 recommendations. The Minister's Forum on Health and Social Services has reviewed these documents, and we agree they include worthy objectives, and generally, they represent the views of the people we heard from during our community...

The latitudinal gradient of the start of the growing season (SOS) and the end of the growing season (EOS) were quantified in Alaska (61°N to 71°N) using satellite-based and ground-based datasets. The Alaskan evergreen needleleaf forests are sparse and the understory vegetation has a substantial impact on the satellite signal. We evaluated SOS and EOS of understory and tundra vegetation using time-lapse camera images. From the comparison of three SOS algorithms for determining SOS from two satellite datasets (SPOT-VEGETATION and Terra-MODIS), we found that the satellite-based SOS timing was consistent with the leaf emergence of the forest understory and tundra vegetation. The ensemble average of SOS over all satellite...

This dissertation studies the impress of Cold War military investment on Alaska's cultural landscape. From 1946 through 1989, Alaska served as the United States' Cold War sentinel and the air defense shield against the threat of Soviet attack over the North Pole. During the Cold War the US military was a dominant force in the state economy and by the end of the period had built approximately 435 military facilities and installations in Alaska, ranging in size from those contained in individual, isolated buildings to massive, self-contained cities. This investment has had different types and degrees of impacts on different places. The study explores these patterns with respect primarily to the facilities' temporal...

Post-fire regrowth is an important component of carbon dynamics in Canada's boreal forests, yet observations of structural development following fire are lacking across this remote and expansive region. Here, we used Landsat time-series data (1985–2010) to detect high-severity fires in the Boreal Shield West ecozone of Canada, and assessed post-fire structure for > 600 burned patches (> 13,000 ha) using airborne light detection and ranging (lidar) data acquired in 2010. We stratified burned areas into patches of dense (> 50% canopy cover) and open (20–50% canopy cover) forests based on a classification of pre-fire Landsat imagery, and used these patches to establish a 25-year chronosequence of structural development...

Experiments have been conducted with a regional climate model to indicate the conditions required to generate preferred regions of frontal activity in the Alaskan region. Several objective methods of frontal identification were first investigated. It was found that· the vertical component of relative vorticity,· a thermal front parameter -&nablaB;|&nablaB;Tsub 850] | · n, where Tsub 850] is the 850-hPa temperature and n is a unit vector in the direction of the 850-hPa temperature gradient, and· a parameter derived from the Q vector as a measure of vertical motionwere useful in combination to determine the occurrence of fronts. The preferred locations for frontal activity were located to the southern side of the...

A selective review of lichenometry as used to date Holocenemoraines in five diverse regions of Alaska and in southeastern Kamchatka suggests that growth curves for this North Pacific areamay be improved by attention to several factors. These includedlichen identification, control point number and distribution,radiocarbon calibration, alternative curve models, andcompatibility of lichen growth rate with climate. Support forcontrol points presented for Kamchatka and published for Alaska areas will benefit from supplementary control at and beyond thebreak from the great growth curve segments of the last centuries.With regard to alternative-linear, logarithmic, and compositecurve-models drawn for the published lichenometric...

Recent studies have shown that ice duration in lakes and rivers over the Northern Hemisphere has decreased over the 19th and 20th centuries in response to global warming. However, lake ice trends have not been well documented in Canada. Because of its size, considerable variability may exist in both freeze-up and break-up dates across the country. In this paper, results of the analysis of recent trends (1951-2000) in freeze-up and break-up dates across Canada are presented. Trends toward earlier break-up dates are observed for most lakes during the time periods of analysis which encompass the 1990s. Freeze-up dates, on the other hand, show few significant trends and a low degree of temporal coherence when compared...

Predictions of future fire activity over Canada's boreal forests have primarily been generated from climate data following assumptions that direct effects of weather will stand alone in contributing to changes in burning. However, this assumption needs explicit testing. First, areas recently burned can be less likely to burn again in the near term, and this endogenous regulation suggests the potential for self-limiting, negative biotic feedback to regional climate-driven increases in fire. Second, forest harvest is ongoing, and resulting changes in vegetation structure have been shown to affect fire activity. Consequently, we tested the assumption that fire activity will be driven by changes in fire weather without...

Boreal regions contain more than half of the carbon in forested regions of the world and over 60% of the world's surface freshwater. Carbon storage and the flood control and water filtration provided by freshwaters and wetlands have recently been identified as the most important ecosystem services provided by boreal regions, with a value many times greater than current resource exploitation. Ecosystem services and sensitive ways of detecting their impairment have so far not been fully included in boreal conservation planning. Climate warming, via its effect on permafrost melting, insect damage, and forest fire, threatens to trigger large positive carbon feedbacks that may enhance the concentrations of greenhouse...
