Modern techniques and Old Red problems–determining the age of continental sedimentary deposits with 40Ar/39Ar provenance analysis in west-central Norway
Modern techniques Old Red problems continental sedimentary deposits 40Ar/39Ar provenance analysis
2009/12/3
Ages of continental 'Old Red Sandstone' (ORS) deposits in Norway have been notoriously difficult to obtain due to the paucity of fossil-bearing horizons. In general, 40Ar/39Ar ages from detrital mica ...
Applying biomass and stem fluxes to quantify temporal and spatial fluctuations of an old-growth forest in disturbance
biomass stem fluxes temporal and spatial fluctuations old-growth forest
2010/1/21
A subtropical old-growth forest was studied over a twelve-year period to investigate temporal and spatial fluctuations of biomass and stem fluxes under disturbances. Vegetations were categorized into ...
Mineral fertilization did not affect decay of old lignin and SOC in a 13C-labeled arable soil over 36 years
Mineral fertilization decay lignin SOC 13C-labeled arable soil

Retardation of soil organic carbon (SOC) decay after nitrogen addition to litter or soil has been suggested in several recent studies and has been attributed to a retardation in lignin decay. With our...

The similarity of the vertical displacements shown by case-history extreme-magnitude earthquakes are scrutinised (Chile 1960, Alaska 1964, Sumatra 2004, ...). A common interpretation – an uprising of ...
Warming mineralises young and old soil carbon equally
Warming mineralises young and old soil carbon
2010/1/13
The temperature sensitivity of soil organic carbon decomposition is critical for predicting future climate change because soils store 2-3 times the amount of atmospheric carbon. Of particular controve...
