Indigenous observations of climate change in the Lower Yukon River Basin, Alaska Indigenous observations of climate change in the Lower Yukon River Basin, Alaska
Natural science climate change studies have led to an overwhelming amount of evidence that the Arctic and Subarctic are among the world's first locations to begin experiencing climate change. Indigenous knowledge of northern regions is a valuable resource to assess the effects of climate change on the people and the landscape. Most studies, however, have focused on coastal Arctic and...

Anthropogenic aerosols as a source of ancient dissolved organic matter in glaciers Anthropogenic aerosols as a source of ancient dissolved organic matter in glaciers
Glacier-derived dissolved organic matter represents a quantitatively significant source of ancient, yet highly bioavailable carbon to downstream ecosystems. This finding runs counter to logical perceptions of age–reactivity relationships, in which the least reactive material withstands degradation the longest and is therefore the oldest. The remnants of ancient peatlands and forests...

Mercury export from the Yukon River Basin and potential response to a changing climate Mercury export from the Yukon River Basin and potential response to a changing climate
We measured mercury (Hg) concentrations and calculated export and yield from the Yukon River Basin (YRB) to quantify Hg flux from a large, permafrost-dominated, high-latitude watershed. Exports of Hg averaged 4400 kg Hg yr-1. The average annual yield for the YRB during the study period was 5.17 μg m-2 yr-1, which is 3–32 times more than Hg yields reported for 8 other major northern...

A 50-year record of NOx and SO2 sources in precipitation in the Northern Rocky Mountains, USA A 50-year record of NOx and SO2 sources in precipitation in the Northern Rocky Mountains, USA
Ice-core samples from Upper Fremont Glacier (UFG), Wyoming, were used as proxy records for the chemical composition of atmospheric deposition. Results of analysis of the ice-core samples for stable isotopes of nitrogen (δ15N, ) and sulfur (δ34S, ), as well as and deposition rates from the late-1940s thru the early-1990s, were used to enhance and extend existing National Atmospheric...

Water quality in the Yukon River Basin, Alaska, water years 2006-2008 Water quality in the Yukon River Basin, Alaska, water years 2006-2008
The Yukon River Inter-Tribal Watershed Council and the U.S. Geological Survey developed a water-quality monitoring program to address a shared interest in the water quality of the Yukon River and its relation to climate. This report contains water-quality data from samples collected in the Yukon River Basin during water years 2006 through 2008. A broad range of chemical analyses from 44...
