The study focuses on the current state of englacial Lake Dålk (Larsemann Hills Oasis), which was completely devastated in January 2017 by a catastrophic outburst and formed again in February 2020. A set of works including ground-penetrating radar (GPR) profiling, geodetic survey, core drilling, thermometric measurements and isotopic analysis was performed. As a result, new data were obtained about the modern boundaries of the reservoir, ice thickness and depths, as well as about the peculiarities of freezing of the lake after re-formation. Based on the field data obtained, one-dimensional mathematical modeling of Lake Dålk freezing was carried out, the results of which showed further scenarios of its evolution.

该研究重点关注英格兰冰川湖 Dålk（拉尔斯曼山绿洲）的现状，该湖于 2017 年 1 月因灾难性爆发而被完全摧毁，并于 2020 年 2 月再次形成。一系列工作包括探地雷达 (GPR) 剖面、大地测量进行了勘察、岩心钻探、温度测量和同位素分析。结果，获得了有关水库现代边界、冰厚度和深度以及湖泊重新形成后结冰特性的新数据。根据获得的现场数据，对达尔克湖结冰进行了一维数学建模，其结果进一步展示了其演变过程。
