This book was released on 1987 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cataclysmic eruption of Mount St. Helens, Washington, on 18 May 1980, filled nearby Spirit Lake with timber and volcanic debris and completely blocked the lake's natural outlet. The lake, which the outlet had previously kept in hydrological balance, was hence-forth impounded in a closed, hydrologically unstable basin by a debris dam 150-180m thick. This event greatly altered the limnology of Spirit Lake and resulted in extremely poor water quality. Some post-eruption water quality characteristics included whole-lake anoxia, which persisted for months; and extraordinarily high concentrations of sulfides, methane, reduced iron and manganese, phosphorus, and dissolved organic matter. Concentrations of total bacteria were thought to be unprecedented for natural lakes. Keywords: Limnology, Water quality, Bacteriology, Biogeochemical processes, Volcanic effects, Lakes.

Concentrations of total bacteria reached 1X10 cells/ml, thought to be unprecedented for natural lakes. This report describes the post-eruption limnological recovery of Spirit Lake, Washington, 1980 to 1986. Other topics of discussion include the limnological impacts of lake drawdown, the effects of Spirit Lake release flows on receiving waters in the North Fork Toutle River basin, and the bacteriology of lakes and rivers in the Mount St. Helens blast zone. Keywords: Limnology; Water quality; Bacteriology; Biogeochemical processes; Volcanic effects; Lakes.

This book was released on 2018-01-30 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book builds on existing work exploring succession, disturbance ecology, and the interface between geophysical and biological systems in the aftermath of the 1980 eruptions of Mount St. Helens. The eruption was dramatic both in the spatial extent of impacts and the range of volcanic disturbance types and intensities. Complex geophysical forces created unparalleled opportunities to study initial ecological responses and long-term succession processes that occur in response to a major contemporary eruption across a great diversity of ecosystems—lowland to alpine forests, meadows, lakes, streams, and rivers. These factors make Mount St. Helens an extremely rich environment for learning about the ecology of volcanic areas and, more generally, about ecosystem response to major disturbance of many types, including land management. Lessons about ecological recovery at Mount St. Helens are shaping thought about succession, disturbance ecology, ecosystem management, and landscape ecology. In the first five years after the eruption several syntheses documented the numerous, intensive studies of ecological recovery. The 2005 volume “Ecological Responses to the 1980 Eruption of Mount St. Helens” (Springer Publishing) was the first ecological synthesis since 1987 of the scores of ecological studies underway in the area. More than half of the world’s published studies on plant and animal responses to volcanic eruptions have taken place at Mount St. Helens. The 25-year synthesis, which generally included investigations (i.e., data) from 1980-2000, made it possible to more thoroughly analyze initial stages of ecological responses and to test the validity of early interpretations and the duration of early phenomena. And 35 years after the eruption, it is time for many of the scientists working in the first three-decade, post-eruption period to pass the science baton to the next generation of scientists to work at Mount St. Helens, and a synt hesis a t this time of transfer of responsibility to a younger cohort of scientists will be an enormous asset to the continuation of work at the volcano.

This book was released on 2006-01-16 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1980 eruption of Mount St. Helens caused tragic loss of life and property, but also created a unique opportunity to study a huge disturbance of natural systems and their subsequent responses. This book synthesizes 25 years of ecological research into of volcanic activity, and shows what actually happens when a volcano erupts, what the immediate and long-term dangers are, and how life reasserts itself in the environment.
