Soil was exposed to red phosphorous/butyl rubber (RP/BR) aerosols at various relative humidities in a recirculating environmental wind tunnel. Soil microbial and enzymatic activities were measured immediately after exposure and periodically thereafter for 56 days. The…

The motion of a strong line thermal in an unstratified atmosphere is modeled to estimate a bound for its capability to life firebrand particles. It is found that the maximum height of a viable firebrand is roughly proportional to the square root of thermal strength. The…

The high variablility of burning conditions and fuels, found in Alaskan forest fires, produces an associated complex emission of particulate matter. Histological evidence of some large particles has been found in the forest fire plumes as well as aerosols resulting apparently…

Patterns of undisturbed nutrient cycling in northern ecosystems and the impact of fire on nutrient cycling are reviewed and discussed. The various effects of fire on ecosystem nutrient cycling may be broadly subdivided into (1) nutrient redistribution during fire, and (2)…

'Two studies were undertaken. An initial study in 1974 produced results that indicated significant losses of nitrogen and some other elements. The study was repeated 1981 as a check on the results of the 1974 burn, and to provide an assessment of the methods used in the first…

Fire links the biosphere and the atmosphere. The linkage is, as yet, poorly quantified. Evidence suggests that a few percent of total C fixed by photosynthesis is oxidized by burning. Biomass burning seems to be globally significant in terms of associated: • Releases of trace…
