A hazai tozeglapok (tozegek) osztalyozasa. (The classification of local peat-bogspeats)
The classification serves both the protection and the various utilization of peat-bogs all the more unless top urgent steps are taken in 30-50years they disappear in Hungary. (CK).
Climatic and anthropogenic influences on radial growth of scots pine at Hanvedsmossen, a raised peatbog, in south central Sweden
Dendrochronology ; Dendrology ; Drainage ; Human impact ; Palaeobiogeography ; Palaeoclimate ; Peatbog ; Sweden
Past studies of the climatic influence on tree growth at peatbogs in northern latitudes have shown weak correlation between annual tree-ring widths and climatic parameters during the growing season. At Handvedsmossen, a raised peatbog in south
central Sweden, tree-ring width chronologies from one drained and one undrained growth site, as well as one dry site outside the bog, were compared to meteorological records.
Lightning and special peatbog phenomena on Andøya, northern Norway
Atmospheric electricity ; Humid environment ; Mass movement ; Norway ; Peatbog
In 1982 a 5 m2 slab of peat, 25 cm thick, was discovered on a peatbog on the island of Andøya. Then, investigations on Andøya have provided information on 6 quite similar phenomena with slab weights varying between 100 kg and 4 tons. Outside Andøya
Dissolved organic carbon dynamics in a restored peatbog in Northwest Germany
The article deals with terms of peat decomposition, bog restoration, UV-Vis spectroscopy, restoration success, humic acid and fulvic acid fraction. The study was carried out in the Pietzmoor in Northwest Germany. - (IfL)
soils is a major limitation. Peat however has very favourable electrical characteristics resulting in low attenuation and excellent results are obtained from GPR surveys. Several examples Southern Belgium are discussed showing the wide range of possible
Peat-bog evaporation is widely unknow and misused in ecological management. The paper presents two locations where this parameter is to be evaluated precisely. Various measurements technics for scientists and managers are introduced. They show
that evapotranspiration in peat-bog is underestimated. - (BJ)
Mire induction, ecosystem dynamics and lateral extension on raised bogs in the southern coastal area of Finland
C 14 dating ; Coastal environment ; Ecosystem ; Finland ; Humid environment ; Hydrodynamics ; Peatbog ; Stratigraphy ; Swamp
The origins, development and lateral extension of the mire ecosystems of five raised bogs in Southern Finland representing different mire complex types were studied by means of 71 basal peat radiocarbon dates, stratigraphic analyses and morphometric
The form of raised peat mires can be considered to reflect the form of the saturated water mound. Here, the form of the mire is calculated for non-uniform, depth-dependent hydraulic conductivity of the peat deposit. Although requiring more
computational effort, the alternative model may offer a more appropriate description of the structure of the peat mire.
Specific part of wide complex of preventive measures against floods and extreme droughts could be procedures realized in river headstream areas. In order to increase a water retention in headwaters the detailed analysis of peatbogs hydrological
Multiproxy record of late Pleistocene-Holocene climate and vegetation changes from a peatbog in Patagonia
Argentina ; C 14 dating ; Deuterium ; Isotope analysis ; Model ; Moss ; Palaeo-ecology ; Palaeoclimate ; Patagonia ; Peatbog ; Pollen ; Quaternary
Pollen assemblage changes and stable hydrogen isotope analysis of mosses from a bog in Tierra del Fuego, Argentina, provided independent proxies for reconstructing changes in effective moisture and temperature over the past 16,000 cal yr B.P
. A deterministic model was used to reconstruct the stable hydrogen isotope composition of meteoric water from the D/H ratios of bog mosses over the last 16,000 years.
The importance of peatbogs are assessed from the balneology, gardening and agriculture or for the formely energy perspectives, or from the landscape evolution in the Holocene (hydrological function, refugium of glacial relicts, etc). The lakes were
The importance of topographic factors on the distribution of bog and heath in a Newfoundland blanket bog complex
Canada ; Ecosystem ; Geographical information system ; Humid environment ; Newfoundland ; Numerical model ; Peatbog ; Photogrammetry ; Quantitative analysis ; Soil water ; Topography
Three blanket bog sites on the southeastern lobe of the Avalon Peninsula, Newfoundland, were studied. Terrain shape characteristics such as slope, plan and profile curvature, and upslope catchment area were derived from digital elevation models
of surface and mineral substrate, and analysed using Partition d'un Ensemble Géographique pour l'Analyse Spatiale Ecologique (PEGASE). Although lower elevations were more favourable for bog development, bog communities persisted in upper elevations in areas
The AA. argue that the premise on which the peat mound model developed by Armstrong (1995) is based, that hydraulic conductivity shows an exponential decline with depth in bogpeats, is unsound. Empirical evidence in the literature
Radiocarbon dates from the inter-tidal peat bed at Portrush, County Antrim
Biogeography ; C 14 dating ; Intertidal zone ; Ireland ; Northern Ireland ; Peatbog
Two new 14C dates from a bed of compact inter-tidal peat at Mill Strand, Portrush, are reported and discussed in relation to two previously obtained ages from peat at Dhu Varren, a short distance inland. The date from the top of the Mill Strand peat
is statistically inseparable from that of the peat top at Dhu Varren. Together these dates indicate the cessation of peat growth occurred -6950-6550 cal. BP as a result of sand deposition associated with sea-level rise. However, dated samples from deeper within
Mapping contemporary magnetic mineral concentrations in peat soils using fine-resolution digital terrain data
Cartography ; Digital elevation model ; England ; Gully erosion ; Hydromorphic soil ; Magnetic susceptibility ; Peatbog ; Soil properties ; Topography ; United Kingdom ; Yorkshire
Recent adavances in the field od digital terrain analysis and the avaibility of fine-resolution digital elevation models means that the relationship between the concentration of magnetic minerals in peat soils and topography can be explored using
quantitative methods. Alport Moor is an ombotrophic peat moorland in the Peak District National Park, UK, where 24 peat cores were collected. Each core was analysed for mass specific magnetic susceptibility. The mapping results demonstrate that the contemporary
concentration of magnetic minerals in the peat soils of Alport Moor is controlled by micro- and local-scale variations in water table position.
Paleohydrological records from peat profiles and speleothems in Sutherland, northwest Scotland
C 14 dating ; Comparative study ; Holocene ; Palaeo-environment ; Palaeoclimate ; Palaeohydrology ; Peatbog ; Pollen diagram ; Quaternary ; Scotland ; Thermoluminescence ; United Kingdom
This paper provides independent paleohydrological data from widely spaced replicate profiles from a Scotish peatland and compares these with the paleoenvironmental records of a nearby cave and its overlying peat. The main aim is to test
