Small scale controls of greenhouse gas release under elevated N deposition rates in a restoring peat bog in NW Germany
In Central Europe, most bogs have a history of drainage and many of them are currently being restored. Success of restoration as well as greenhouse gas exchange of these bogs is influenced by environmental stress factors as drought and atmospheric nitrogen deposition. We determined the methane and nitrous oxide exchange of sites in the strongly decomposed center and less decomposed edge of the ...
متن کاملSource characterisation of atmospheric platinum group element deposition into an ombrotrophic peat bog.
Platinum, palladium, rhodium, iridium and osmium were found to be enriched relative to their expected natural concentrations in peat samples from Thoreau's Bog, an ombrotrophic peat bog in Concord, Massachusetts. The source of osmium into the bog was determined from its isotopic composition (187Os/188Os). Osmium is composed of 4% lithogenic osmium from atmospheric soil dust, 41% of anthropogeni...
متن کاملReconstructing historical atmospheric mercury deposition in Western Europe using: Misten peat bog cores, Belgium.
Four sediment cores were collected in 2008 from the Misten ombrotrophic peat bog in the Northern part of the Hautes Fagnes Plateau in Belgium. Total mercury (Hg) concentrations were analyzed to investigate the intra-site variability in atmospheric Hg deposition over the past 1,500 years. Mercury concentrations in the four cores ranged from 16 to 1,100 μg kg(-1), with the maxima between 840 and ...
متن کاملAccumulation of Radionuclides in Peat Deposits of Bog Ecosystems in the Urals
Studies of the last decades have shown that peat and peat-bogs function as an important factor for environment protection. Due to good take-up and filtering qualities, peat-bog deposits perform to absorb petroleum products, different natural and human-made chemical and radioactive pollutants. Due to low salinity of bog water and turf humic acids, the peat-bed is capable to extract cations of ca...
متن کاملEuropean Bog Bodies: From the Iron Age Peat Bog to the 21st Century
Well preserved bodies dating from the prehistoric era to the 19th century have been found across northwestern Europe; specifically in the peat bogs of Ireland, Great Britain and Denmark. These discoveries were especially prevalent in the late 19th and early 20th centuries when mass peat extraction was at its height. Many of these finds have been dated to the Iron Age and have previously been at...
