Full-layer drilling to reveal a mechanism for growth and preservation of ultra multi-year landfast ice

Sea-ice cores are sampled with the mechanical drill system to reveal a mechanism for growth and preservation of multi-year landfast sea ice. Using core samples, physical and chemical characteristics of sea ice are analysed.研究人员借助机械钻探系统采集海冰岩心，旨在揭示多年固定海冰的生长与保存机制。依托上述岩心样本，可对海冰的物理与化学特性开展分析工作。
