abstract = "We collected snow samples from two pits with depths of 4.02 and 3.18 m at the East Greenland Ice Core Project camp (75?37?N, 35?59?W), Greenland in the summer of 2016 to estimate recent annual snow deposition and examine seasonal variation in major ion species, stable isotopes of water and microparticles (dust). Dating based on clear seasonal variation in chemical components indicated that the 4.02- and 3.18-m-deep pits included snow deposition corresponding to ten years from 2006 to 2016 and seven years from 2009 to 2016, respectively. The mean values for annual snow deposition for the 4.02-m-deep pit were 138 and 145 mm yr? 1 in water equivalent (mm w.e. Yr? 1) in 2006?2016 and 2009?2016, respectively. The average deposition for the 3.18-m-deep pit was 149 mm w.e. Yr? 1 between 2009 and 2016. Seasonal variation in concentrations of major ion species and dust were similar to those previously reported for Greenland. The maximum Cl-/Na+ concentration ratios in the summer were much higher than the ratios at other sites in Greenland.",
