Book excerpt: Excerpt from Precipitation and Streamwater Chemistry in an Undisturbed Watershed in Southwest Alaska To understand the biogeochemical behavior of terrestrial ecosystems, a budgetary approach, which assesses inputs to and outputs from small water shed ecosystems, is often used. Lnvestigations into the control of inputs and outputs of elements have been made through intensive measurements of single watersheds. Paired watersheds are often used to measure land management impacts. Departures in water chemistry in the treatment water shed are attributed to the management activity. This approach has produced hypotheses for the understanding of specific situations. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2007-12-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over 15 years with seven years of pretreatment calibration measurements, a year of treatment, and seven years of post-treatment monitoring. The research was a cooperative effort with scientists from Oregon State University, Oregon Department of Fish and Wildlife, the U.S. Geological Survey, and the U.S. Environmental Protection Agency. Cooperating landowners included the Georgia-Pacific Corporation, the U.S. Forest Service, and a local rancher. It was a remarkable 15-year partnership marked by excellent cooperation among the participants and outstanding coordination among the scientists, many of whom participated actively for the entire period.

Delbecq and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coastal watersheds of Southeast Alaska have diverse hydrologic regimes driven by differences in the contribution of glacial, snow, and rainwater inputs to streamflow. Climate change is set to shift watershed streamflow regimes, which has the potential to impact the source, processing, and export of materials (e.g., organic matter, nutrients, drifting macroinvertebrates) from watersheds to nearshore ecosystems. However, the impact of streamflow variability, such as droughts and floods, on material transport is poorly understood in Southeast Alaska. My study evaluated how streamflow variability impacts the magnitude and composition of materials exported from a predominantly rain-fed watershed in Juneau, Alaska. I collected stream drift and water chemistry samples at least twice per week from late April through October 2021, capturing peaks and troughs in stream flow during the main runoff season. I found that dissolved organic carbon (DOC) dominated streamwater carbon export, except during low flow periods in July and August when alkalinity was the dominant form of carbon export. Relative to DOC and alkalinity, streamwater export of particulate organic matter and invertebrates was small, but these carbon sources could be disproportionately important to downstream food webs because of their higher quality, assessed from molar ratios of C to N. Furthermore, hourly measurements of DOC and alkalinity collected with in situ sensors revealed differing seasonal relationships between concentration and discharge (CQ), as well as potential effects of antecedent stream flow conditions. Shifts in streamflow regimes and/or enhanced variability in flow owing to climate change will alter the form, magnitude, and timing of material exports from rain-fed watersheds in Southeast Alaska. Shifting patterns of material export could in turn alter land-to-ocean linkages that may be important for productivity and resilience of freshwater and marine food webs.
