Photomineralization apparent quantum yield at 309 nm for DOC leached from permafrost soils collected from the North Slope of Alaska in the summer of 2015

Dissolved organic carbon (DOC) was leached from permafrost soils near the Toolik Field Station in the Alaskan Arctic and then characterized for its photochemical properties.  The apparent quantum yield of photomineralization (photochemical carbon dioxide, CO2, production) of permafrost DOC was quantified at 309 nm.

研究人员从阿拉斯加北极地区图利克野外站（Toolik Field Station）附近的永久冻土土壤中淋溶得到溶解态有机碳（Dissolved organic carbon, DOC），并对其光化学特性进行了表征；同时在309纳米波长下，定量测定了该永久冻土DOC的光矿化（光化学二氧化碳（CO₂）生成）表观量子产率。
