Particulate organic carbon (POC) concentration in meltwater runoff of Leverett Glacier, Russell Glacier, and Isunnguata Sermia, southwest Greenland (2009-2018)

This dataset describes particulate organic carbon (POC) and particulate carbon (PC) concentrations of suspended sediments in the proglacial rivers of 3 land-terminating glaciers in the Kangerlussuaq area, Southwest Greenland: Leverett Glacier (LG), Leverett River; Russell Glacier (RG), Akuliarusiarsuup Kuua; and Isunnguata Sermia (IS), Isortoq River. Both the Leverett River and Akuliarusiarsuup Kuua are tributaries of the Qinnguata Kuussua (also known as Watson River). The data have already been part of 3 different publications (Lawson et al. 2014, Kohler et al. 2017, and Vrbická et al. 2022) but are archived here for the first time. POC data was collected for LG during the 2009 and 2010 melt seasons (Lawson et al. 2014) as well as 2015 (Kohler et al. 2017). For the 2018 melt season, only total carbon concentrations of suspended sediments (PC) is archived as opposed to POC (see Vrbická et al. 2022).

本数据集记录了格陵兰西南部康克鲁斯瓦格地区3座陆地末端冰川的冰前河流中悬浮沉积物的颗粒有机碳（POC）与颗粒碳（PC）浓度，涉及的冰川及对应河流分别为：勒韦特冰川（Leverett Glacier, LG）与勒韦特河、拉塞尔冰川（Russell Glacier, RG）与阿库利亚鲁苏普库阿河、伊孙瓜塔塞尔米亚冰川（Isunnguata Sermia, IS）与伊索托克河。勒韦特河与阿库利亚鲁苏普库阿河均为钦瓜塔库苏阿河（亦称沃森河）的支流。上述数据此前已被纳入3项不同的学术出版物（Lawson等，2014；Kohler等，2017；Vrbická等，2022），但本次为首次在此归档。针对勒韦特冰川（LG）的POC数据采集于2009、2010年融季（Lawson等，2014）及2015年（Kohler等，2017）；2018年融季仅归档了悬浮沉积物的总碳浓度（即颗粒碳PC），而非颗粒有机碳POC（详见Vrbická等，2022）。
