Status of soil acidification in North America Status of soil acidification in North America
Forest soil acidification and depletion of nutrient cations have been reported for several forested regions in North America, predominantly in the eastern United States, including the northeast and in the central Appalachians, but also in parts of southeastern Canada and the southern U.S. Continuing regional inputs of nitrogen and sulfur are of concern because of leaching of base cations

Results of the acid rain program: Status and trends of emissions and environmental impacts (1990–2002) Results of the acid rain program: Status and trends of emissions and environmental impacts (1990–2002)
Both SO2 and NOx emissions from power generation sources have significantly declined under Title IV. In 2002, SO2 emissions from Title IV-affected sources totaled 10.2 million tons and NOx emissions from all Title IV-affected sources totaled 4.5 million tons, down 35% and 33% respectively from 1990 levels. Sources in states with the highest emissions continue to reduce their emissions...

Assessing acid deposition: Advances in the state of science Assessing acid deposition: Advances in the state of science
NAPAP has a long history of conducting research related to acid deposition. Throughout the 1980s NAPAP supported a large number of research projects that confirmed the link between SO2 and NOx emissions and acidic lakes and streams hundreds of miles away. Recent research is confirming the tight link between emissions of SO2 and the amount of several different forms of sulfur in the...

Evidence for intensification of the global water cycle: Review and synthesis Evidence for intensification of the global water cycle: Review and synthesis
One of the more important questions in hydrology is: if the climate warms in the future, will there be an intensification of the water cycle and, if so, the nature of that intensification? There is considerable interest in this question because an intensification of the water cycle may lead to changes in water-resource availability, an increase in the frequency and intensity of tropical...

Assessment of calcium status in Maine forests: Review and future projection Assessment of calcium status in Maine forests: Review and future projection
Forest harvesting and acidic deposition can cause substantial decreases in the calcium (Ca) inventory of forest soils if such losses are not replenished through mineral weathering, atmospheric deposition, or fertilization. The net balance between losses and gains defines the forest Ca status. Site-specific studies have measured Ca pools and fluxes in Maine forests, but no synthesis has...

Changes in the number and timing of days of ice-affected flow on northern New England rivers, 1930-2000 Changes in the number and timing of days of ice-affected flow on northern New England rivers, 1930-2000
Historical dates of ice-affected flows for 16 rural, unregulated rivers in northern New England, USA were analyzed. The total annual days of ice-affected flow decreased significantly (p 0.1) over the 20th century at 12 of the 16 rivers. On average, for the nine longest-record rivers, the total annual days of ice-affected flow decreased by 20 days from 1936 to 2000, with most of the...

Summer low flows in New England during the 20th Century Summer low flows in New England during the 20th Century
High springtime river flows came earlier by one to two weeks in large parts of northern New England during the 20th Century. In this study it was hypothesized that late spring/early summer recessional flows and late summer/early fall low flows could also be occurring earlier. This could result in a longer period of low flow recession and a decrease in the magnitude of low flows. To test...
