Development of GIS datasets for selected aquifers in New York

Problem - Since the 1980s, the U.S. Geological Survey (USGS) has mapped over 30 sand and gravel aquifers in upstate New York at the 1:24,000-scale. These mapped aquifers include both the primary and many of the principal aquifers as designated by the New York State Department of Environmental Conservation. Although the 1:24,000-scale maps are valuable in their present form, their usefulness is...

The Effects of Watershed and Stream Liming on Mercury Dynamics at Honnedaga Lake

Problem The Adirondack region of New York has 128 lakes that are listed as impaired by acidity under section 303(d) of the Clean Water Act. Acidity can limit the survival and reproduction of native fishes such as brook trout (Salvelinus fontinalis). Chronic and episodic acidification also stresses fish, aquatic macroinvertebrates, and other biota of inflowing tributaries of these and many...

Effects of Stream Restoration and Bank Stabilization on Suspended Sediment in Tributaries to the Upper Esopus Creek

Introduction The upper Esopus Creek watershed is located in the eastern Catskill Mountains of New York State and covers 497 km2 from Slide Mountain, the highest peak in the Catskills at 1,274 m, to the Ashokan Reservoir at 193 m elevation (fig. 1). Suspended sediment and turbidity are primary water quality concerns in the Ashokan Reservoir watershed, part of the New York City Catskill-Delaw...

Groundwater Flow Patterns near Pulaski, Oswego County, New York

Problem - The Village of Pulaski in Oswego County, N.Y., obtains its water supply from groundwater that drains under gravity from an unconfined aquifer into three shallow dug wells. The well field is in an area where groundwater discharges to springs along the west edge of the Tug Hill Aquifer, which is comprised of beach and kame deposits of sand and gravel. A numerical groundwater model wa...

Ground-water-flow model of the Shenandoah Valley, Virginia and West Virginia

Problem - Increasing development within the Shenandoah Valley in recent years has placed additional demands on the region’s water resources. The sedimentary rocks in the Valley have been compressed and folded by tectonic forces to form a 5-km deep basin. Ground water, a principal component of the available water supply, flows through fractures in the sedimentary and crystalline rocks that un...

Limited contribution of ancient methane to surface waters of the U.S. Beaufort Sea shelf

In response to warming climate, methane can be released to Arctic Ocean sediment and waters from thawing subsea permafrost and decomposing methane hydrates. However, it is unknown whether methane derived from this sediment storehouse of frozen ancient carbon reaches the atmosphere. We quantified the fraction of methane derived from ancient sources...

Greenhouse gas emissions from diverse Arctic Alaskan lakes are dominated by young carbon

Climate-sensitive Arctic lakes have been identified as conduits for ancient permafrost-carbon (C) emissions and as such accelerate warming. However, the environmental factors that control emission pathways and their sources are unclear; this complicates upscaling, forecasting and climate-impact-assessment efforts. Here we show that current whole-...
