Available in PDF, EPUB and Kindle. Book excerpt: The presence of suspended sediment in marine waters has several impacts, such as a degradation of the coastal ecosystem, pollution or a damaging effect on the tourism-oriented economies. FIELD_AC is a European project that aims to provide an improved operational service for coastal areas and generate added value for GMES predictions. This is achieved by the analysis of field cases. In this context, this minor thesis is based on the study of the information obtained in a field campaign carried out on Barcelona's near shore between November of 2010 and January of 2011. The data studied in this minor thesis was acquired in two different deployments: A1 and A2, located at 24 m depth in front of the combined sewer overflow of Bogallet and in front of the Besós river mouth respectively. These deployments consisted of a concrete structure provided with an AWAC current profiler, able to measure current velocities and wave parameters, and two different SSC sensors: a turbidimeter and an optical backscatter. In the first place, a quality control of the measurements provided by the instruments is done in order to verify its validity in relation to each instrument measuring range and in relation to the expected behaviour for each parameter. The only instruments that show problems with the validity of the measurements are the turbidimeters and the optical devices. Data acquired until the 8th of December shows optimal reliability. From that date until the 5th of January, turbidity data suffers a decrease of reliability and from the 5th of January onward, turbidity measurements are not valid, as the behaviours observed cannot be explained by natural processes. In the second place, the validated data is studied. Including meteorological conditions (wind, atmospheric pressure and rainfall), sea level, wave climate (significant wave height, maximum wave height, period and direction), currents and continental inputs (combined sewer overflow spills and river discharges). These parameters are the driving forces that control sediment transport processes. In the third place, sediment fluxes, current shear stress, wave shear stress and critical conditions for resuspension are calculated and significant SSC increase events are identified. Finally, each turbidity increase event is studied thoroughly in order to establish the agents responsible for the presence of sediment in the water column. Three agents are observed to have the capability of incorporating sediment to the water column in Barcelona's near shore: waves, currents and offshore fluxes of continental inputs.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago Polar Biology published the book, Weddell Sea Ecology, containing the European "Polarstern" study EPOS in the Weddell Sea and Peninsula waters 1988/89. In certain respects, the present collection of papers, first published in Polar Biology in 2001, is a follow-up as it combines papers partly based on three "Polarstern" expeditions to the same region. Further articles relate to both land-based and shipborne studies, again primarily in the Atlantic sector and around the Antarctic Peninsula. The SCAR programme, "Ecology of the Antarctic Sea Ice Zone" (EASIZ), served as an umbrella for a truly international cooperation. Although funding came exclusively from national sources, 40% of the scientists on board "Polarstern" were foreigners. Out of the 35 papers of the present volume not less than 14 papers have multinational authorship. The scope of EASIZ is wider ilian the Southern Ocean Studies in JGOFS and GLOBEC. The Contents reflect emphasis on the study of benthos, which hitherto had not received the necessary attention in the attempt to understand key questions of evolution and zoogeography of fauna from the Southern Hemisphere. The information collected under EASIZ enhanced greatly our recognition of the rather high biodiversity of ilie Antarctic shelf benthos. In order to extend these studies to ilie deeper continental slopes and the deep sea, "Polarstern" is presently on her way for ilie first international survey of deep-sea benthos in the Atlantic sector of ilie Southern Ocean.

This book was released on 1992 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a scientific journal like "Oecologia Aquatica" reaches its tenth issue, it is perhaps not an occasion for extraordinary celebration. However, if it turn out that this coincides with a series of unusual circunstances, then the perspective changes somewhat. Moreover, if the editors hasten to confess that this modest milestone of issue na 10 was really taken as an excuse to pay tribute to Professor Ramon Margalef, who was the founder, the first director and the driving force behind the journal, we can be forgiven for waiting to celebrate.

Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Download or read book The Spanish Coastal Systems written by Juan A. Morales and published by Springer. This book was released on 2018-09-03 with total page 823 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the state of art of the geologic knowledge about the Spanish coast obtained through scientific research in the last 30 years.From a general point of view, coasts are the most quickly changing systems of the Earth. This is critical, since many human resources, such as the main part of economic and social activities, are located in the coastal areas. Especially in the case of Spain these coasts include cities, wide industrial areas (including harbor complexes), important ecologic systems, and our main economic resource: tourism. Understanding the dynamic functioning of each element of this coast is vital for correct future coastal management, so as to solve problems derived from bad plans developed in the last decades of the twentieth century. This is a valuable text for advanced graduate students and coastal researchers, which connects the specific dynamic functioning of the main Spanish coastal environments and their relationships with human activities.
