Available in PDF, EPUB and Kindle. Book excerpt: Some 90 years ago, the first information on the occurrence of dissolved organic matter in sea water was published. For 50 years after that reve lation, little progress was made in identifying these dissolved "yellow substances." In the 1950s and 1960s, a few chemical oceanographers identified some specific dissolved organic compounds, but few of these pioneers fully appreciated their significance in terms of biological inter actions, metal chelation, or interactions with sedimentary material. When Mohammed Rashid began his work on marine humic compounds in the mid-1960s, he was one of only five scientists who had specifically designed their studies toward understanding the nature of these complex materials. Over the next decade, Dr. Rashid directed his research toward characterization of humic and fulvic compounds in the marine environ ment, the influence of humic substances on the growth of marine phy toplankton, the role of organic matter in complexing metals in sea water and marine sediments, the interaction between humic substances and clay minerals in marine environments, and the influence of organic matter on the geotechnical properties of marine sediments. As if the many papers produced from these scientific investigations were not sufficient, Dr.

This book was released on 2009 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter two discusses Mo behavior in three sites from the anoxic Mexican continental margin. The data from these sites suggest that a unique Mo isotopic signature exists for authigenic Mo enrichments in anoxic sediments. Chapter three discusses Mo geochemical and isotopic behavior from a variety of marine environments to further constrain Mo behavior during early diagenesis. At sites representing end-member cases for oxic and anoxic conditions, the observed sediment Mo isotope compositions agree with those predicted from previously reported natural and laboratory fractionations. However, data from surface sediments of several study sites suggest that Mo associated with organic matter has an isotopic composition that is less fractionated (relative to modern seawater) than either oxic or anoxic authigenic Mo phases, and that this biogenic Mo may dominate the bulk sediment Mo pool in certain environments. In addition, redox cycling of Mn within the sediment column appears to strongly influence Mo geochemical and isotopic behavior. Chapter four investigates sediment geochemistry along a depth transect in Lake Tanganyika, East Africa. Permanent stratification of waters in this lake has produced a strong chemocline, with oxic conditions in the surface and sulfidic waters at depth. The sediment distributions of trace metals (specifically Mo and U) along this transect are investigated herein to evaluate changes in sediment geochemistry across this transition. Despite sulfur limitation in this freshwater system, conditions are sufficiently reducing (particularly at depths below the chemocline) to generate substantial authigenic metal enrichments.
