Metabolism and water chemistry of tundra ponds near Utqiagvik, Alaska, 2019–2024

Low centered polygon ponds and thermokarst trough ponds were sampled near Utqiagvik, AK in late summer from 2009-2024 to understand how pond types differ in chemistry and C flux. Water samples from open water were characterized for nutrients concentration and algal biomass. Carbon and oxygen concentrations were monitored continuously using sensors.

2009年至2024年夏末，研究团队在阿拉斯加州乌特恰维克（Utqiagvik）周边采集了低中心多边形池塘与热融喀斯特槽形池塘的样本，以探究不同类型池塘在化学特征与碳通量（C flux）方面的差异。对开放水域采集的水样进行了分析，测定其营养盐浓度与藻类生物量。研究人员采用传感器对碳与氧浓度开展了连续监测。
