This book was released on 2007 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Restoration of the Salton Sea, a large salt lake in the desert area of southeastern California, is presently under consideration by state and federal agencies. It experiences wildly fluctuating fish populations, algal blooms and occasions of anoxia with toxic levels of hydrogen sulfide. Overturn events, caused by windstorms, occur from early summer to early fall leading to upwelling. These are associated with patches of bright green water with low oxygen and high sulfide levels in surface waters, called "green tides", and are visible by satellite. Orders of magnitude drops in both phytoplankton and zooplankton populations occur in these green waters. Phytoplankton was studied over the three years 1997-1999 as well as in fall 2005 during a "green tide" event. Major groups were dinoflagellates, diatoms, cryptomonads and a raphidophyte. A euglenoid was often abundant in green waters. Biovolume densities and chlorophyll a concentrations each year were highest in spring and lowest within green waters in August or September. An increase in abundance of large cells and colonial algae over the three years is attributed to a release in grazing pressure due to the decline in the planktivorous fish, tilapia. Ciliates were the major protozooplankters but usually accounted for less than half of the zooplankton in 1997-1999. Large ciliates increased in abundance over the three-year period, likely due to decreasing fish populations. An anaerobic ciliate, Sonderia sp., became abundant during the anoxic green water events. Anecdotal reports of "green tides" date back decades. Usually attributed to algal blooms, these are due to suspended microscopic gypsum crystals. Formed when sulfide-rich bottom waters mix into oxygen-rich surface waters, the crystals give a bright signal in the green waveband, and serve as an indicator of these sulfide irruptions. Gypsum blooms have been observed by satellite every year during 1979-1985 and 1998-2006, generally in summer or fall and in mid-lake, lasting days to a week or more. Their occurrences has been also been accompanied by mass mortalities of fish and have increased in intensity and duration since 2002 due to a decrease in fish populations and an increase in decomposition of organic matter at depth
Download or read book The Salton Sea Centennial Symposium written by Stuart H. Hurlbert and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with many aspects of the physical and chemical limnology of the Salton Sea, California’s largest lake and a lake that may soon to be the object of a multi-billion dollar restoration project. Formed in 1905 by an accidental breaching of outtake structures on the Colorado River, and maintained since then by large and steady inflows of agricultural wastewaters, it has long served as an important habitat for fish and waterbirds and as a major recreational area for people. Highlly eutrophic and with a salinity that is steadily rising and now nearly 50 g/L, it is a lake in great trouble. Most fish species have disappeared, and large fish and bird dieoffs have been common in recent decades. Many of the papers in this volume represent studies undertaken with the aim of informing the re-engineering of this ecosystem so that its value to wildlife and man can be restored or enhanced.

This book was released on 2013-06-29 with total page 703 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of papers presented to the Fourth Internation~l Symposium on Environmental Biogeochemistry (ISEB), and a conference on Biogeochemistry in Relation to Mining Industry and Environmental Pollution (Leaching Conference), held in Canberra, Aust ralia on August 26-31 and September 3-4, 1979, respectively. The ISEB were established to provide "a forum for uninhibited exchange of information and ideas among the biological, chemical, atmospheric and geolorical scientists working in the common area of biogeochemistry, encompassing soil and other earth sciences as well as the hydrosphere and atmosphere", By linking the fourth ISEB with the Leachin~ Conference the scope of discussions was extended to encompass the application of biogeochemical processes to the mining industry. This wide-ranging philosophy is reflected in the breadth and diversity of the subjects covered in this book. The published papers are expanded versions of those presented at the meetings. They have all been scrutinized by at least one referee in addition to the editors. About 20% of the contributions to the meetings are not included, either because authors did not wish to publish or because the papers were not accepted by the editors.
