英文摘要: To evaluate the influence of long-distance transport of charcoal particles on the detection of local wildfires from lake sediment sequences, we tracked three consecutive years of charcoal deposition into traps set within seven boreal lakes in northeastern Canada. Peaks in macroscopic charcoal accumulation (>150 μm) were linked to both local (inside the watershed) and regional wildfires. However, regional fires were characterized by higher proportions of small particles (<0.1 mm2) in charcoal assemblages. We conclude that the analysis of particle size distribution is useful to discriminate "true" local fires from regional wildfires. Key Points Charcoal accumulation was monitored during 3 years in seven lakesLocal (close) and regional (distant) wildfires both produced charcoal peaksLocal and regional fires had different charcoal size distributions ©2014.
