Abstract The paper presents information on the studies of the first-year ice ridges conducted by the AARI experts in April–May 2016 in 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. The results of a detailed study of one of the ice ridges are presented. The sail height varied from 2.5 up to 3.4 m, the keel depth varied from 8.3 up to 10.3 m. The average thickness of the consolidated layer was 2.2–2.4 m. Cross-sectional profiles of the ice ridge are illustrated. Ratio of the mean CL thickness of ice ridge to the mean thickness of level ice was equal 1.7. The distribution of salinity in the upper part of the CL is Z-shaped, and on the scale of the entire ice column, C-shaped. The CL growth rate is approximately twice as high as the growth rate of level ice. It was detected that the ridged ice was slightly stronger than the level ice. The porosity of the ice ridges is investigated in Part II.

绍卡尔斯科戈海峡冰脊研究结果，第一部分：原位形态和物理参数

摘要 本文介绍了 AARI 专家于 2016 年 4 月至 5 月在 Shokal'skogo 海峡（Severnaya Zemlya 群岛）进行的第一年冰脊研究的信息，使用热水钻探并记录了穿透率。钻孔主要沿脊脊横截面以 0.25 m 为间隔钻孔。介绍了对其中一个冰脊的详细研究结果。船帆高度从 2.5 到 3.4 m 不等，龙骨深度从 8.3 到 10.3 m 不等。固结层的平均厚度为2.2-2.4 m。图示了冰脊的横截面轮廓。冰脊的平均 CL 厚度与水平冰的平均厚度之比等于 1.7。CL 上部盐度分布呈 Z 型，在整个冰柱的尺度上，C形。CL 的增长率大约是水平冰增长率的两倍。检测到，脊冰比水平冰略强。第二部分研究了冰脊的孔隙度。
