Reasons for drilling:1. Study of geological structure of the north-western Barents Sea shelf according to the programs of study of Arctic geology and creating geological reference points for reliable referencing of geophysical data.2. Detailed correlation with regional geological-geophysical sections of Late Paleozoic, Mesozoic and Paleogene deposits.Technical results:The hole was drilled from 10.01.1985 till 14.07.1987. It has penetrated the section of 2481 m and stopped in Early Carboniferous deposits.Scientific results:1. Comprehensive lithologic and paleontological studies (based on different fauna groups) of drill samples from the hole have allowed to reveal lithologic features and to carry out a detailed lithologic and stratigraphic sequence of Permian, Mesozoic and Paleogene sedimentary rocks.2. Thicknesses of the units are as followed: Early Carboniferous - 61 m, Middle-Late Triassic - 409 m, Jurassic - 151 m, joint Late Jurassic - Early Cretaceous - 93 m, Early Cretaceous - 971 m, Paleogene - 762 m, ...
