DOWNLOAD EBOOKMarine dissolved organic matter (DOM) is a complex mixture of molecules found throughout the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon in the oceanic water column, posited to be a source of atmospheric climate regulation. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, focuses on the chemical constituents of DOM and its biogeochemical, biological, and ecological significance in the global ocean, and provides a single, unique source for the references, information, and informed judgments of the community of marine biogeochemists. Presented by some of the world's leading scientists, this revised edition reports on the major advances in this area and includes new chapters covering the role of DOM in ancient ocean carbon cycles, the long term stability of marine DOM, the biophysical dynamics of DOM, fluvial DOM qualities and fate, and the Mediterranean Sea. Biogeochemistry of Marine Dissolved Organic Matter, Second Edition, is an extremely useful resource that helps people interested in the largest pool of active carbon on the planet (DOC) get a firm grounding on the general paradigms and many of the relevant references on this topic. Features up-to-date knowledge of DOM, including five new chapters The only published work to synthesize recent research on dissolved organic carbon in the Mediterranean Sea Includes chapters that address inputs from freshwater terrestrial DOM

DOWNLOAD EBOOKA substantial increase in the number of studies using the optical properties (absorbance and fluorescence) of dissolved organic matter (DOM) as a proxy for its chemical properties in estuaries and the coastal and open ocean has occurred during the last decade. We are making progress on finding the actual chemical compounds or phenomena responsible for DOM’s optical properties. Ultrahigh resolution mass spectrometry, in particular, has made important progress in making the key connections between optics and chemistry. But serious questions remain and the last major special issue on DOM optics and chemistry occurred nearly 10 years ago. Controversies remain from the non-specific optical properties of DOM that are not linked to discrete sources, and sometimes provide conflicting information. The use of optics, which is relatively easier to employ in synoptic and high resolution sampling to determine chemistry, is a critical connection to make and can lead to major advances in our understanding of organic matter cycling in all aquatic ecosystems. The contentions and controversies raised by our poor understanding of the linkages between optics and chemistry of DOM are bottlenecks that need to be addressed and overcome.

DOWNLOAD EBOOKOur results to date have provided proof of concept for application of EEMS to ocean chemistry, biology, optics, and tracer studies. EEMS has provided new insight into the chemical composition of DOM in natural waters. Fluorescence spectroscopy can provide a rapid, underway, real-time method for distinguishing between various pools of DOC and to look for transport of newly-formed DOC Out of the euphotic zone. Analysis is rapid enough to permit sampling a spacial resolution similar to that of other hydrographic parameters, such as nutrients. This gives us the ability to for the first time to incorporate DOC compositional information into large scale circulation models, thereby increasing our understanding of DOC cycling in the ocean and providing new insights into pathways, sites, and rates of DOC transformation. Elaboration of differences in spectral properties due to gelbstoff source and the conditions under with measurements are made should also lead to improvement of radiative transfer model. The linear relationship between CDOM fluorescence and salinity could provide an optical tracer amenable to remote sensing techniques using passive or active sensors. Passive sensors have been used successfully to produce surface salinity maps from AVIRIS data based on gelbstoff absorption (Carder et al. 1993). Data of this type could be extremely useful in coastal waters where remote sensing separated surface temperature pans alone do not permit extrapolation of water mass distribution and mixing.

DOWNLOAD EBOOKThe representation of the Earth's surface in global monitoring and forecasting applications is moving towards capturing more of the relevant processes, while maintaining elevated computational efficiency and therefore a moderate complexity. These schemes are developed and continuously improved thanks to well instrumented field-sites that can observe coupled processes occurring at the surface–atmosphere interface (e.g., forest, grassland, cropland areas and diverse climate zones). Approaching global kilometer-scale resolutions, in situ observations alone cannot fulfil the modelling needs, and the use of satellite observation becomes essential to guide modelling innovation and to calibrate and validate new parameterization schemes that can support data assimilation applications. In this book, we review some of the recent contributions, highlighting how satellite data are used to inform Earth surface model development (vegetation state and seasonality, soil moisture conditions, surface temperature and turbulent fluxes, land-use change detection, agricultural indicators and irrigation) when moving towards global km-scale resolutions.
