Book excerpt: The long term goal of this research is to examine the processes that control trace metal concentrations in near-shore waters. Within this context, we examine the role of chemical exchange across the sediment-water interface and the examine how changes in harbor processes will affect water column trace metal burdens. This research represents the collaboration between scientists with expertise on biogenic matter degradation (W.B., USC) and trace metal analyses (K. Coale and K. Johnson, Moss Landing Marine Labs) with the long-term goal to develop and integrated understanding of trace metal behavior in near-shore sediments.

Book excerpt: The long term goals of this project are to examine the influence of metal flux (primarily Cu, Cd, As, Co, Mn and Fe) from sediments on the concentration of dissolved metals in the coastal zone and embayments. The processes that control trace metal exchange across the sediment-water interface within coastal environments regulate the concentration of dissolved, bioactive metals in the water column. These processes include variations in the relative influence of transport mechanisms (diffusion versus bio-irrigation), microbial activity (anaerobic versus aerobic respiration), as well as geochemical reactions (redox reactions, precipitation, complexation and adsorption) that regulate the behavior of dissolved metals in pore waters. All of these processes are controlled by the activity and composition of the sediment community. The role of organic carbon remineralization on trace metal mobility at a biologically active interface is, therefore, the focus of this study.

This book was released on with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 15 years, there has been steady growth in work relating to the microbial iron cycle. It is now well established that in anaerobic environments coupling of organic matter utilization to Fe reduction is a major pathway for anaerobic respiration. In iron-rich circumneutral environments that exist at oxic-anoxic boundaries, significant progress has been made in demonstrating that unique groups of microbes can grow either aerobically or anaerobically using Fe as a primary energy source. Likewise, in high iron acidic environments, progress has been made in the study of communities of microbes that oxidize iron, and in understanding the details of how certain of these organisms gain energy from Fe-oxidation. On the iron scarcity side, it is now appreciated that in large areas of the open ocean Fe is a key limiting nutrient; thus, a great deal of research is going into understanding the strategies microbial cells, principally phytoplankton, use to acquire iron, and how the iron cycle may impact other nutrient cycles. Finally, due to its abundance, iron has played an important role in the evolution of Earth’s primary biogeochemical cycles through time. The aim of this Research Topic is to gather contributions from scientists working in diverse disciplines who have common interests in iron cycling at the process level, and at the organismal level, both from the perspective of Fe as an energy source, or as a limiting nutrient for primary productivity in the ocean. The range of disciplines may include: geomicrobiologists, microbial ecologists, microbial physiologists, biological oceanographers, and biogeochemists. Articles can be original research, techniques, reviews, or synthesis papers. An overarching goal is to demonstrate the environmental breadth of the iron cycle, and foster understanding between different scientific communities who may not always be aware of one another’s work.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

This book was released on 2014-03-04 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Geological Survey (USGS) personnel have assessed trace-metal concentrations in sediments and sediment-dwelling species since 1977 at an intertidal site in the vicinity of the discharge of the Palo Alto Regional Water Quality Control Plant (PARWQCP). They have also profiled that area's benthic community structure since 1974. Ancillary factors that could affect metal concentrations (body weight in animals, characteristics of sediment, salinity) and benthic community structure (exotic species invasions, pelagic food availability, and weather anomalies) have also been measured during this time.
