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.

我们于2016年夏季从格陵兰岛东格陵兰冰芯项目营地（北纬75°37′N，北纬35°59′W）的两个深度分别为4.02和3.18 m的坑中收集了雪样，以估算最近的年度积雪并进行检查主要离子种类的季节性变化，水和微粒（粉尘）的稳定同位素。根据明显的化学成分季节性变化进行的约会表明，深4.02米和3.18米的矿坑分别包含积雪，分别对应于2006年至2016年的十年和2009年至2016年的七年。在2006–2016年和2009–2016年，深4.02米深的矿坑的年度积雪平均值分别为138和145 mm yr ^-1的水当量（mm we Yr ^-1）。深3.18米的坑的平均沉积为149 mm we Yr ^-1在2009年至2016年之间。主要离子种类和粉尘浓度的季节性变化与之前报道的格陵兰岛相似。最大氯^- /钠⁺在夏季集中率比格陵兰其他网站的比例要高得多。
