Atmospheric Deposition and Surface-Water Chemistry in Mount Rainier and North Cascades National Parks, U.S.A., Water Years 2000 and 2005-2006
David W. Clow, Donald H. Campbell
2008, Scientific Investigations Report 2008-5152
High-elevation aquatic ecosystems in Mount Rainier and North Cascades National Parks are highly sensitive to atmospheric deposition of nitrogen and sulfur. Thin, rocky soils promote fast hydrologic flushing rates during snowmelt and rain events, limiting the ability of basins to neutralize acidity and assimilate nitrogen deposited from the atmosphere. Potential...
River Channel Topographic Surveys Collected Prior to and Following Elevated Flows in the Central Platte River, Spring 2008
Paul J. Kinzel
2008, Data Series 380
Rainfall in central Nebraska in late May and early June 2008 elevated streamflows in the central Platte River. Topographic surveys collected along geomorphic monitoring transects prior to these flows (May 2007, July 2007, and March 2008) were repeated in mid-June 2008. These surveys provide characterization of river topography that could...

2008, Book chapter, Developments in integrated environmental assessment
Current uncertainty in quantifying the global carbon budget remains a major contributing source of uncertainty in reliably projecting future climate change. Furthermore, quantifying the global carbon budget and characterising uncertainties have emerged as critical to a successful implementation of the United Nations Framework Convention on Climate Change and its Kyoto Protocol. Beyond fundamental quantification, attribution...

2008, Ecology (89) 3534-3541
Summarizing complex temporal dynamics in communities is difficult to achieve in a way that yields an intuitive picture of change. Rank clocks and rank abundance statistics provide a graphical and analytical framework for displaying and quantifying community dynamics. We used rank clocks, in which the rank order abundance for each...
