Mercury Cycling and Bioaccumulation in the Upper Hudson River Basin--Fishing Brook

BackgroundDetailed investigations of mercury cycling and bioaccumulation have been done in the Upper Hudson River basin (upstream of the Hudson River near Newcomb, in New York's Adirondack Mountains, with a focus on the Fishing Brook sub-basin, part of the western headwaters of the Hudson River. This study is part of a National mercury study that includes a concurrent study of McTier Creek, a...

Assessing Spatiotemporal Patterns in Fish Assemblages from Acid-Sensitive Streams in the Adirondack and Catskill Mountains

Background With few exceptions, the contemporary and past effects of acidification on fish populations and communities in streams across acid-sensitive regions of NY have not been documented. The pervasive lack of information only permits anecdotal insight into the spatial effects of acidification on stream-fish assemblages and essentially precludes any broad effort to quantify temporal tre...

Bathymetry of New York City's West of Hudson Reservoirs

Background Every day, the New York City Department of Environmental Protection (DEP) supplies more than one billion gallons of drinking water to more than nine million people. To do this, the DEP maintains an extensive network of reservoirs and aqueducts. A major part of this system, the West of Hudson (WOH) network, in the Delaware and Hudson River drainages, includes six reservoirs (fig. 1...

305b Ambient Groundwater Quality Monitoring in New York

Introduction Relatively little data describing the quality of groundwater in New York State exists, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the 305(b) groundwater quality monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate Ne...

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...

The migratory bird treaty and a century of waterfowl conservation

In the final decades of the nineteenth century, concern was building about the status of migratory bird populations in North America. In this literature review, we describe how that concern led to a landmark conservation agreement in 1916, between the United States and Great Britain (on behalf of Canada) to conserve migratory birds shared by...

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-...
