The paper presents information on the studies of the first-year ice ridges conducted by the AARI experts in April–May 2018 in the fast ice of the Shokal'skogo Strait (Severnaya Zemlya Archipelago) using hot water drilling with computer recording of the penetration rate. Boreholes were drilled along the cross-section of the ridge crest at 0.25 m intervals mainly. One of the ice ridges had an unusual configuration: the sail crest was on the edge of the perpendicular extended keel crest. Cross-sectional profiles of ice ridges are illustrated. The records of thermodrilling rate revealed the presence of residual ice fragments in the keel of the ice ridges. The sail height varied from 2.9 up to 3.2 m, the keel depth varied from 8.5 up to 9.6 m. The average keel depth to sail height ratio varied from 2.8 to 3.3, and the thickness of the consolidated layer was 2.5–3.5 m. The porosity of the unconsolidated part of the keel was about 23–27%. The distributions of porosity versus depth for all ice ridges are presented and discussed.

本文介绍了AARI专家于2018年4月至5月在Shokal'skogo海峡（Severnaya Zemlya群岛）的速冻冰上进行的第一年冰岭研究的信息，该研究使用了热水钻探并通过计算机记录了渗透率。沿脊顶的横截面主要以0.25 m的间隔钻孔。其中一个冰脊具有不寻常的构造：帆峰位于垂直延伸的龙骨峰的边缘。示出了冰脊的横截面轮廓。热钻速率的记录表明，在冰脊龙骨中存在残留的冰块。帆高从2.9到3.2 m不等，龙骨深度从8.5到9.6 m不等。平均龙骨深与帆高之比从2.8到3.3，固结层的厚度为2.5-3.5 m。龙骨未固结部分的孔隙率约为23–27％。介绍并讨论了所有冰脊的孔隙度与深度的关系。
