First-year ice ridge has been examined with respect to geometry and morphology at the Barneo ice camp in April 2013. Its characteristics are discussed in the paper. The sail height was 4.7 m, the keel depth was 8.6 m. The keel depth to sail height ratio was equal to 1.8. Structure of the keel of the examined ice ridge was too heterogeneous in its composition. Significant fragment in the keel of ice ridge is fully consolidated, its draft reaches to 5.8 m but the fragment's upper boundary is located at the sea level. This indicates the presence of hydrostatic unbalance. Away from the point of maximum keel draft on the cross-section, the average porosity of the unconsolidated part of the keel tends to increase, but again decreases at the periphery of the keel. The distribution of ice fraction in sea ice versus depth for the ice ridge is presented. Increased ice fraction corresponds to the consolidated layer. The depth of the lower boundary of consolidated layer is confirmed by distributions of ice temperature versus depth.

2013 年 4 月在 Barneo 冰营对第一年冰脊的几何形状和形态进行了检查。本文讨论了其特征。风帆高度为 4.7 m，龙骨深度为 8.6 m。龙骨深度与帆高比等于 1.8。被检查的冰脊龙骨的结构在其组成上过于异质。冰脊龙骨中的重要碎片完全固结，其吃水深度达到5.8 m，但碎片的上边界位于海平面。这表明存在流体静力不平衡。远离横截面上的最大龙骨吃水点，龙骨松散部分的平均孔隙率趋于增加，但在龙骨周边再次降低。给出了海冰中冰分数的分布与冰脊深度的关系。增加的冰分数对应于固结层。固结层下边界的深度由冰温与深度的分布确定。
