为了确定格陵兰岛西北部冰盖上水汽和气溶胶的输送过程，我们在冰盖西北部的一个沿海站点进行了冰川学观测，揭示了地表雪和积雪中δO和化学物质浓度的空间变化。在出口冰川（Meehan冰川）上，水汽和海盐从海岸输送。在格陵兰西北部内陆冰盖上，来自海洋浮游植物的水汽、矿物粉尘、NO3和SO4等人为物质以及CH3SO3等从格陵兰西海岸经格陵兰冰盖中部输送。
To determine the transport processes of water vapor and aerosols over the northwestern Greenland ice sheet, we undertook a glaciological observation at a coastal site on the northwestern part of the ice sheet and revealed spatial variations in δO and in the concentrations of chemical substances in surface snow and the snowpack. On the outlet glacier (the Meehan glacier), water vapor and sea salt were transported from the coast. On the inland ice sheet in northwestern Greenland, water vapor, mineral dust, anthropogenic substances such as NO3 and SO4, and CH3SO3 from marine phytoplankton were transported from the west coast of Greenland via the central part of the Greenland ice sheet.
