ABSTRACT
The Adirondack Mountain region of New York is one of the most intensively studied regions of the world with respect to the effects of acidic deposition on aquatic resources. Acidic deposition effects research in the Adirondacks has played an important role in many of the areas of major scientific advancement. Elevations range from about 30 m near Lake Champlain to 1630 m in the High Peaks area of the northeastern Adirondacks. Precipitation chemistry is generally rather uniform across the Adirondack region. Total atmospheric deposition of S has been estimated by D. L. Sisterson et al. and C. T. Driscoll et al. are to be in the range of 9 to 12 kg S/ha per year in the Adirondacks. The accumulation and release of sulphur and nitrogen in seasonal snowpacks are important factors that influence the delivery of atmospheric deposition to soils and surface waters in the Adirondacks.
