Book Description
The definitive ecological guide to the Gulf of MexicoEstuaries Today the ecological health of the Gulf of Mexico--long the base ofvast commercial fisheries--is at risk from a potent array ofthreats, from increased nutrient inputs to the loss of coastalwetlands that impact water quality. Never before has knowledge of the biogeochemical processes of theGulf's estuaries and wetlands been so critical to its preservation,and yet until now research on this vital area has beenfragmented. Biogeochemistry of Gulf of Mexico Estuaries offers a comprehensive,integrated examination of these vital natural resources and theirecology. Featuring contributions from a diverse group of expertscientists from all regions of the Gulf Coast, thisinterdisciplinary reference provides extensive coverage of what isknown about biogeochemical processes--and the factors that regulatethem--in warm temperate and subtropical systems. Organized around aframework that integrates geomorphology, sedimentary processes,nutrient cycling, and trace metals chemistry, it not onlydemonstrates how the Gulf's estuarine systems work, but alsoestablishes a basis for how they compare with other, better-studiedtemperate estuaries. In addition, the book features afascinating--and timely--examination of the effects ofbiogeochemical processes on estuarine management. Biogeochemistry of Gulf of Mexico Estuaries will be welcomed byecologists, marine scientists, environmental activists, and anyoneinvolved with managing these precious natural resources.

Book Description
The Lower Mississippi River, extending from Cairo, Illinois to the Gulf of Mexico, annually transports approximately 170 million tonnes of sediment. Historically, the quantity and calibre of sediment derived from catchment erosion have been affected by changes in land-use and management. For example, soil erosion increased during the 19th and early 20th centuries due to settlement by Europeans and this may have elevated catchment sediment supply to the Mississippi River, while more recently the supply of sediment from tributaries is known to have decreased markedly as a result of river engineering and management. Specifically, the construction of large dams as part of the Mississippi River and Tributaries (MR & T) Project has trapped sediment that would otherwise have been supplied to the Mississippi, particularly by the Missouri River. Marked changes have also occurred in the extent of eroding bankline along the Mississippi and these must have reduced the input of sediment derived from this source. For example, during the last three decades, a sustained construction program of bank revetments and dikes has produced a stable alignment. Given these trends in sediment supply from catchment, tributary and bank sources, it is not surprising that most studies of sediment movement report a large decrease in measured sediment loads at selected monitoring stations along the Mississippi River over the last 50 years (Kesel, 1988; Dardeau and Causey, 1990). However, a case can be made that the bed material load must have increased since the 1940s. This argument is based on analysis of morphological changes observed along the river that have led to an overall increase in slope and available stream power, coupled with the fact that bed material sizes along the river have remained almost constant.
