Lake Mashej, located in the Siberian Altai Mountains, is formed by a dam consisting of a terminal moraine with a covering rockglacier and lateral rockfall debris. Until its outburst in July 2012, the lake developed during the last 400 years up to its maximum extension. Dead tree trunks within the temporary inundated lake basin loged the extension of the lake by the point of time of their death and the environmental conditions within their anual records. By dendroecological analysis of the already sampled tree trunks the development of the lake and the related climatological and environmental signals will be decoded. A previous random test indicated a significant amount of data inherited in the tree rings. In addition to the development of the lake itself, the data might fill a significant gap on the knowledge of the natural environmental development of the area located between Europe and the heart of Central Asia.

马舍伊湖位于西伯利亚阿尔泰山脉，由一座大坝形成，该大坝由终端冰碛、覆盖岩石冰川和侧面落石碎片组成。直到 2012 年 7 月爆发为止，该湖在过去 400 年里一直发展到最大程度。暂时被淹没的湖盆内的死树干记录了它们死亡时湖泊的延伸情况以及年度记录中的环境条件。 通过对已采样的树干进行树木生态学分析，将解码湖泊的发展以及相关的气候和环境信号。之前的随机测试表明树木年轮中继承了大量的数据。除了湖泊本身的发展之外，这些数据还可能填补欧洲和中亚中心地区之间的自然环境发展知识的重大空白。
