The book also covers the development of new geosoftware to effectively process the geochemical data before its interpretation.
No realm on Earth elicits thoughts of paradise more than the tropics. The tropical marine realm is special in myriad ways and for many reasons from seas of higher latitude, in housing iconic habitats such as coral reefs, snow white beaches, crystal clear waters, mangrove forests, extensive and rich seagrass meadows and expansive river deltas, such as the exemplar, the Amazon. But the tropics also has an even more complex side: tropical waters give rise to cyclones, hurricanes and typhoons, and unique oceanographic phenomena including the El Niño- Southern Oscillation which affects global climate patterns. Tropical Marine Ecology documents the structure and function of tropical marine populations, communities, and ecosystems in relation to environmental factors including climate patterns and climate change, and patterns of oceanographic phenomena such as tides and currents and major oceanographic features, as well as chemical and geological drivers. The book focuses on estuarine, coastal, continental shelf and open ocean ecosystems. The first part of the book deals with the climate, physics, geology, and chemistry of the tropical marine environment. The second section focuses on the origins, diversity, biogeography, and the structure and distribution of tropical biota. The third part explores the rates and patterns of primary and secondary production, and their drivers, and the characteristics of pelagic and benthic food webs. The fourth part examines how humans are altering tropical ecosystems via unsustainable fisheries, the decline and loss of habitat and fragmentation, Further, pollution is altering an earth already in the throes of climate change. Tropical Marine Ecology is an authoritative and comprehensive introduction to tropical marine ecology for advanced undergraduate and postgraduate students. It is also a rich resource and reference work for researchers and professional managers in marine science.

Humans have had a long relationship with the ebb and flow of tides on river deltas around the world. The fertile soils of river deltas provided early human civilizations with a means of farming crops and obtaining seafood from the highly productive marshes and shallow coastal waters associated with deltas. However, this relationship has at times been both nurturing and tumultuous for the development of early civilizations. The vicissitudes of seasonal changes in river flooding events as well as frequently shifting deltaic soils made life for these early human settlements challenging. These natural transient processes that affect the supply of sediments to deltas today are in many ways very similar to what they have been over the millennia of human settlements. But something else has been altered in the natural rhythm of these cycles. The massive expansion of human populations around the world in both the lower and upper drainage basins of these large rivers have changed the manner in which sediments and water are delivered to deltas. Because of the high density of human populations found in these regions, humans have developed elaborate hydrological engineering schemes in an attempt to "tame" these deltas. The goal of this book is to provide information on the historical relationship between humans and deltas that will hopefully encourage immediate preparation for coastal management plans in response to the impending inundation of major cities, as a result of global change around the world.
Geology and Geomorphology of Alluvial and Fluvial Fans by D. Ventra,L.E. Clarke Pdf
Alluvial and fluvial fans are the most widespread depositional landform bordering the margins of highland regions and actively subsiding continental basins, across a broad spectrum of tectonic and climatic settings. They are significant to the local morphodynamics of mountain regions and also to the evolution of sediment-routing systems, affecting the propagation and preservation of stratigraphic signals of environmental change over vast areas. The volume presents case studies discussing the geology and geomorphology of alluvial and fluvial fans from both active systems and ancient ones preserved in the stratigraphic record. It brings together case studies from a range of continents, climatic and tectonic settings, some introducing innovative monitoring and analysis techniques, and it provides an overview of current debates in the field. This volume will be of particular interest to geologists, geomorphologists, sedimentologists and the general reader with an interest in Earth science.
