Abstract Annually resolved ice core records from
different regions over the Greenland ice sheet (GrIS)
are used to investigate the spatial and temporal vari-
ability of calcium (Ca2+
, mainly from mineral dust) and
sodium (Na+
, mainly from sea salt) deposition. Cores
of high common inter-annual variability are grouped
with an EOF analysis, resulting in regionally repre-
sentative Ca2+
and Na+
records for northeastern
and central Greenland. Utilizing a regression and
