1. 1. Arctic Loess as an Environmental Archive: Holocene Dust and Wildfire Record in West Greenland

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Lars Petter Hällberg; [2018]
   Nyckelord :aeolian dust; IRSL; luminescence dating; charcoal analysis; magnetic susceptibility; wildfire;

   Sammanfattning : The largest wildfire ever observed in Greenland raged through its tundra during august 2017, and it is unknown if there have been similar wildfires in the area before satellite monitoring began in 1999. Arctic wildfires affect permafrost degradation, carbon storage of soils and the surface albedo of the Greenland Ice sheet – despite this, local fires have previously been ignored by researchers.

3. 2. A high resolution analysis of macroscopic charcoal deposited in peat

   L3-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :David Ventorp; [2007]
   Nyckelord :macrocharcoal; sieving; dendrochronology; peat; forest firest; in-situ; ex-situ;

   Sammanfattning : The amount of macroscopic charcoal in the top 25 cm of three cores from a peat land in Hornsö Ecopark, south-eastern Sweden, was compared to the dendrochronology inferred fire history of the site. Because of the occurrence of a recent fire ex-situ (1999) and one fire ¬in-situ inferred by three fire scared Scots pines, Pinus sylvestris, adjacent (5-10 m) to the peat cores, the site provided an excellent opportunity to compare the abundance of charcoal deposited in a peat land after fires in-situ and ex-situ.
