- Atmospheric aerosols are conservatively archived in polar ice sheets,
which can be used to reconstruct past climate conditions in their
source regions as well as long-range atmospheric transport patterns.
We investigated recent snow chemistry and mineral dust records in
the snow pit recovered from Northern Victoria Land in Antarctica.
We estimated the age of the snow pit to cover approximately 4 years
from 2011 to 2014/2015 based on seasonal variations in δ18O, δD,
and major ion values. Here we present the data record for various
chemical components such as trace elements from the snow samples
using inductively coupled plasma-sector filed mass spectrometry
(ICP-SFMS) equipped with Apex sample introduction systems. We
observed high crustal enrichment factors (EFs) for the elements As,
Bi, Cd, Cu, Mo, Rb, Sb, Tl, and Zn at the depth of 70 ~ 80 cm that
are a summer season in 2013. We focus on analysis of chemical
compositions of individual particles in the samples to understand the
origins of elements using quantitative energy-dispersive electron
probe X-ray microanalysis, called low-Z particle EPMA. The
complementary information obtained from both ICP-SFMS and low-
Z particle EPMA is expected to provide the source of aerosols.
