Description:
It is contested that the mineral dust found in Greenlandic ice cores during the Holocene stems from
multiple source areas. Particles entrained above a more productive, primary source dominate the
signal’s multi-seasonal average. Data in sub-annual resolution, however, reveal at least one further
source.
Whereas distinct inputs from the primary source are visible in elevated concentration levels, various
inputs of the secondary source(s) are reflected by multiple maxima in the coarse particle percentage.
As long as the dust sources’ respective seasonal cycles are preserved, primary and secondary source
can be distinguished.
Since the two source’s ejecta eventually detected differ in size, which can be attributed to a change in
atmospheric residence times, it is suggested that the secondary source is located in closer proximity to
the drilling site than the primary one.
