案例简介：

案例简介：Photo by @paoloverzone / Niko Bornemann, an engineer at the Alfred Wegener Institute (@awiexpedition), does maintenance work at a permafrost temperature measurement station on Sardakh Island, Siberia, Russia. Estimates suggests that more than 1,300 gigatonnes of soil carbon are stored in the permafrost region of the Northern Hemisphere. This is more carbon than is currently in the atmosphere. When Arctic permafrost deposits thaw, microbes decompose formerly frozen organic matter and they release carbon into the atmosphere as greenhouse gases, providing a significant climate-warming feedback loop. However, permafrost carbon pool estimates have high uncertainties and the dynamics of rapid permafrost thaw in a warming Arctic are poorly understood. Measuring permafrost temperatures is a key science task to understand how fast permafrost thaw is happening. The goal of the group of scientists at Alfred Wegener Institute is to “improve the prediction of future interactions between permafrost carbon storage, permafrost's temperature state, and the Earth's climate.” Follow @paoloverzone for more photos and stories.
