Water isotope data collected from precipitation, snow, and rivers, Thule Air Force Base, Northwest Greenland, 2011-2013.

This data package contains oxygen and hydrogen isotope measurements taken from two rivers (Fox Canyon and North Mountain) near Thule, Air Force Base (AFB) in Northwest Greenland. Samples were collected over the course of summer field seasons (2011-2013). This dataset also contains water isotope measurements of snowpack collected from snow pits located on North Mountain near Thule, AFB and precipitation isotopes collected at Thule, AFB. This data is part of a larger study investigating regarding how the Arctic is undergoing structural and functional changes that appear to be the result of climate change, including shifts in vegetation distribution, increases in CO 2 and CH 4 efflux from ecosystems to the atmosphere, and the acceleration of dissolved organic carbon (DOC) export from land to oceans.

本数据包收录了格陵兰西北部图勒空军基地（Thule, Air Force Base, AFB）附近两条河流——福克斯峡谷（Fox Canyon）与北山（North Mountain）的氧、氢同位素测量数据。样品采集工作于2011至2013年的夏季野外考察期间完成。本数据集同时包含从图勒空军基地附近北山的雪坑中采集的积雪包水同位素测量数据，以及在图勒空军基地获取的降水同位素数据。该数据隶属于一项更大规模的研究，该研究旨在探究北极地区如何因气候变化出现结构与功能层面的变化，包括植被分布格局改变、生态系统向大气排放的二氧化碳（CO₂）与甲烷（CH₄）通量增加，以及溶解有机碳（dissolved organic carbon, DOC）从陆地向海洋的输出速率加快。
