The objectives for year have been the gathering of existing information, initiation of monitoring water quality, evaluation of analytical methods and procedures for measuring nutrient regeneration in the sediment-water interface, and the study of growth-environment correlations in Findley Lake, Chester Morse Reservoir, and Lakes Sammamish and Washington. Progress was made...
Federal legislation requires that governmental programs be evaluated on a wide set of criteria to provide policymakers with information on the achievement or lack of achievement of goals and/or objectives. A methodology to identify and quantify measures of achievement is described. In addition, the methodology is designed to facilitate the...
This chapter is divided into three main sections. The first section discusses land cover map development. It begins by providing background information on the regional division of labor and the regional land cover legend. It then focuses on our land cover mapping methods, including a description of data sources, the...

We investigate the freshwater composition of the shelf
and slope of the Arctic Ocean north of the New Siberian
Islands using geochemical tracer data (δ¹⁸O, Ba, and PO₄*)
collected following the extreme summer of 2007. We find
that the anomalous wind patterns that partly explained the sea
ice minimum at...
Studies of the effects of climate change on forests have focused on the ability of species to tolerate temperature
and moisture changes and to disperse, but they have ignored the effects of disturbances caused by climate change
(e.g., Ojima et al. 1991).Yet modeling studies indicate the importance of climate effects...
Fire, other disturbances, physical setting, weather, and climate shape the structure and function of forests throughout the Western United States. More than 80 years of fire research have shown that physical setting, fuels, and weather combine to determine wildfire intensity (the rate at which it consumes fuel) and severity (the...

Longitudinal patterns of fish and benthic invertebrate distribution and
habitat use were similar in Thomas Creek, Oregon but clarity of these patterns
differed. I studied fish and aquatic invertebrates simultaneously, at multiple
scales, and used multivariate statistical techniques to compare responses to the
same environmental conditions. Both types of organisms...
