Concentrations, fluxes and isotopic signatures of greenhouse gases emitted from lakes and ponds on Bylot Island, Nunavut, Canada

Arctic lakes and ponds can be hot spots for greenhouse gas (GHG) emissions, yet studies are scarce, particularly outside the peak summer season. Here we present GHG diffusive and ebullition flux data collected over a decade from a range of water bodies formed on an organic-rich, polygonal landscape originating from syngenetic permafrost. The GHG concentrations and flux data are supplemented with radiocarbon and stable isotope signatures of the emitted gases, together with limnological properties of the studied lakes and ponds.北极湖泊与池塘可成为温室气体（Greenhouse Gas, GHG）排放的热点区域，但相关研究仍较为匮乏，尤其是在夏季排放峰值时段之外的时期。本数据集提供了十年间从源自共生永久冻土的富有机质多边形地貌上形成的各类水体采集的温室气体扩散通量与冒泡通量数据。同时，数据集还补充了排放气体的放射性碳与稳定同位素特征，以及所研究湖泊和池塘的湖沼学特性。
