  • The aim of this paper is to demonstrate the sedimentology of the Harrinkangas formation and the origin of the enclosed organic remains. This esker contains peat layers and is covered by thin silty till. The AA. argue that it is possible to explain
  • this stratigraphy as a result of redeposition of organic matter through subglacial processes during the last glaciation.

  • In this lecture detailed attention has been paid to the occurrence of organic matter in the Rhine. Several kinds of organic matter have been distinguished. Organic micropollution is described. (H. Winteraeken).
  • Sulfidic materials in the western Mekong delta, Vietnam
  • Alluvium ; Clay mineral ; Delta ; Marine sediment ; Organic materials ; Sea level ; Soil ; Soil properties ; Vietnam
  • On the basis of exploratory soil surveys and joint field work by Dutch and Vietnamese soil scientists during February 1984 and September 1985, the different kinds of sulfidic materials in the western Mekong delta are described and their distribution
  • is presented in the form of a generalized map. Two main kinds of sulfidic materials have been recognized.

  • in organic material generated within different ecological habitats and confirm the highly dynamic nature of organic cycling within the wetland environment. - (AJC)
  • The paper presents the preliminary results of geomorphological and sedimentological investigations in the Ncamasere Valley, a seasonally back-flooded tributary of the Okavango River. Studies of organic horizons within cores indicate the differences

  • Seasonal changes in iron transport and nature of dissolved organic matter in a humic river in northern Finland
  • Finland ; Geochemistry ; Hydrology ; Iron ; Organic materials ; Seasonal variation ; Streams ; Water quality
  • Changes in the concentration of iron and dissolved organic matter (DOM), and in the colour and fluorescence properties in the River Küminkijoki were investigated as functions of the seasonal flow regime over a two-year period. Discussion
  • Kisérlet a tarsadalom térbeliségének torténelmi materialista értelmezésére. (Experiment at the interpretation of the spatial organization of society from the aspect of historical materialism)
  • Soil fauna in arid ecosystems: their role and functions in organic matter cycling
  • Arid area ; Biogenic process ; Ecosystem ; Fauna ; Micro-organism ; Organic materials ; Rainfall simulation ; Soil ; Soil properties
  • This short paper is based in part on the information available on the actual functioning and composition of the soil community. The soil biota activity, which utilizes the organic matter for biosynthesis and maintenance at different levels
  • of organization, has a considerable effect on arid regions. This activity is stongly affected by abiotic factors which are highly unstable especially in a desert ecosystem.
  • Spatial distributions of organic carbon and nitrogen and their isotopic compositions in sediments of the Changjiang Estuary and its adjacent sea area
  • Carbon ; China ; Coastal sedimentation ; Estuary ; Geochemistry ; Isotope analysis ; Jiangsu ; Nitrogen ; Organic materials ; Spatial distribution
  • The spatial distribution patterns of total organic carbon and total nitrogen show significant correlations with currents of the East China Sea Shelf. The purposes of this paper are to analyze characteristics of stable carbon and nitrogen isotopes
  • in seabed sediments, and discuss their implications for tracing organic matter source; and calculate contributions of different organic matter sources in seabed sediments.
  • Trace metals, organics and nutrients that are adsorbed onto suspended particles affect the supply of these materials to phytoplankton and zooplankton. Fecal pellets are important in fjords, an aqueous environment that is dominated by the vertical
  • flux of suspended sediments. Pelletization also allows the transport of undigested food to greater depths providing an important source of organic material to benthic sediments and food to deep-water organisms.

  • Discussion of the results of the investigations of organic matter in the SW Atlantic, in the Polar Frontal Zone. The present goal was organic matter distribution at the period of its accumulation and bacterioplankton activization anomalously warm
  • δC 13 of loess organic matter as a potential proxy for paleoprecipitation
  • Carbon ; Climatic index ; Germany ; Isotope analysis ; Loess ; Methodology ; Organic materials ; Palaeo-environment ; Precipitation ; Rhine ; Valley
  • High-resolution paleoprecipitation reconstructions for the last glaciation based on the isotopic record organic matter in loess from Nussloch (Rhine Valley, Germany) are consistent with paleoprecipitation inferred from peat in the same area using
  • an independant method. Thus, δC 13 of loess organic matter can be used as a proxy for paleoprecipitation.
