    Abstract. In this study, temporal variability of nosZ genotypes was evaluated in two intertidal rocky biofilms and two intertidal sediment sites of the Douro River estuary, Portugal. The results were compared to rates of key N-cycle processes and environmental variables to examine possible links between denitrifier community dynamics and N biogeochemistry.

    Microphytobenthos (MPB) are an important nitrogen (N) sink in coastal systems, but little is known about the fate of N assimilated by MPB. We used an in situ 15 N pulse‐chase experiment in intertidal, nonpermeable, sandy mud to trace the assimilation, transformation, and loss from the sediment of MPB‐N over 31 d. Following assimilation, 15 N was tightly retained in surface sediments, with. Methods.

Involving a wide range of scientists working on intertidal sediments, this book is of importance to all environmental scientists. Individual chapters explore the underlying biogeochemical processes controlling the behaviour of carbon, the nutrients nitrogen and phosphorus, and contaminants such as toxic organics, trace metals and artificial radionuclides in intertidal environments.

About this book Involving a wide range of scientists working on intertidal sediments, this book is of importance to all environmental scientists. Individual chapters explore the underlying biogeochemical processes controlling the behaviour of carbon, the nutrients nitrogen and phosphorus, and contaminants such as toxic organics, trace metals and artificial radionuclides in intertidal Range: £ - £ Summary: This book will be important for all scientists studying saltmarshes or intertidal muds around the world.

The biogeochemistry of these environments is critical to understanding their ecology and management. Biogeochemistry of surficial sediments in the intertidal systems of a tropical environment.

Chemistry and Ecology: Vol. 24, No. 4, pp. The particle size showed a large degree of heterogeneity between the upper and the lower beach.

The upper beach was composed of very permeable coarse sands and gravels, whereas the surface sediment of the seepage zone, which constituted the main part of the studied beach, consisted of well sorted particles composed of fine sand with a median grain size of ± 10 μm and a POC concentration Author: Aurélia Mouret, Céline Charbonnier, Pascal Lecroart, Edouard Metzger, Hélène Howa, Bruno Deflandre.

Jickells, J. Rae. One of the largest tidal flat systems in the world is the Wadden Sea (Fig. 1a) where high rates of primary production in the water column and efficient cycling of nutrients in the intertidal flat sediments are tightly coupled (Poremba et al.,Billerbeck.

The book focuses on concepts and quantitative understanding of primary production, organic matter mineralization and sediment biogeochemistry.

The impact of biogeochemical processes. The intertidal sediment is dominated by mud and fine sand, with about 67% and 95% of the sediment grain size finer than 50 μm and μm, respectively [Yang et al., ]. Tidal current and river runoff cause a distinct salinity gradient in the estuary, with a range from 0 to 30 [ Li et al., ].
