Abstract

The ice-gouging topography of bed of the southwestern Kara Sea is the result of the impact of icebergs and sea ice. During cruise 52 of the R/V Akademik Nikolaj Strakhov using a multibeam echo sounder, we collected representative data on the key parameters of ice scours (location, orientation, depth, width) for the first time, which allows us to draw conclusions on a regional scale. We revealed regularities in the spatial and temporal distribution of ice scours and their density in different parts of the seabed. It was revealed that the maximum dimensions of the ice scours decrease with distance from the sources of iceberg calving from NW to SE. The orientation of the ice scours correlates with the main drift directions of icebergs. Most of the ice scours are located at depths up to 220 m and could have formed both at the modern and lower sea levels (in postglacial time). We identified a high degree of seabed transformation by ice-gouging processes in the southwestern Kara Sea.

喀拉海西南部的冰蚀形态学
摘要喀拉海西南部海床的冰刨地形是冰山和海冰撞击的结果。在 Akademik Nikolaj Strakhov 号考察船第 52 次航行期间,我们使用多波束回声测深仪首次收集了冰刨关键参数(位置、方向、深度、宽度)的代表性数据,从而可以得出区域范围的结论。我们揭示了冰蚀的时空分布及其在海底不同区域的密度的规律性。结果表明,冰蚀槽的最大尺寸从西北向东南随着与冰山碎裂源的距离减小而减小。冰蚀槽的方向与冰山的主要漂移方向相关。大多数冰蚀槽位于水深 220 米以下,可能在现代海平面和较低海平面(冰川期后)形成。我们在喀拉海西南部发现了冰刨过程对海床的高度改造。
