The glacimarine processes in the Western Antarctic Peninsula have been intensified since the “Little Ice Age”. These have been recorded in the distribution and shape of glacial submarine landforms and glacial sub-bottom stratigraphy. In this study, the dominant factors of the past ice flow behaviour and glacimarine sedimentary processes in Börgen Bay, Anvers Island, are identified and analyzed. The results indicate that the outer bay linear features are associable to the past ice flow during the Last Glacial Maximum. After that, a general deglaciation period occurred, with some readvances and short stillstand, interpreted by the presence of moraines and small transverse ridges. The presence of “pinning points” on the coast, could affect the glacier movements and favour the generation of moraines. Differences in the ice flow behaviour between the bay arms, are due to factors such as bathymetry, and the size of the drainage basin and glacier front. Main sedimentary processes are ice-rafting and subglacial flows, marked by chaotic seismic facies, and gravity flows identified by monticulated and transparent seismic facies, and also sediment plumes contribution, creating laminated facies in the proximal area basins. Those sedimentary mechanisms and landforms agree with a wet polar climate, but some of them would indicate a warmer climate shifting, that is necessary to prove with systematic future measurements.

自“小冰河时代”以来，南极半岛西部的冰川过程加剧。这些在冰川海底地貌和冰川亚底地层的分布和形状中都有记载。在这项研究中，确定和分析了 Anvers 岛 Börgen 湾过去冰流行为和冰川沉积过程的主导因素。结果表明，外湾线状特征与末次盛冰期过去的冰流有关。在那之后，出现了一个普遍的冰消期，有一些再前进和短暂的静止状态，这可以通过冰碛和小的横向脊的存在来解释。海岸上“钉扎点”的存在可能会影响冰川运动并有利于冰碛的产生。海湾臂之间冰流行为的差异是由于水深、流域盆地和冰川前缘的大小等因素造成的。主要的沉积过程是冰漂流和冰下流，以混沌地震相为标志，重力流由单状和透明地震相识别，还有沉积物羽流贡献，在近端地区盆地形成层状相。这些沉积机制和地貌与潮湿的极地气候一致，但其中一些表明气候变暖，这需要通过系统的未来测量来证明。和由单点和透明地震相识别的重力流，以及沉积物羽流贡献，在近端区域盆地形成层状相。这些沉积机制和地貌与潮湿的极地气候一致，但其中一些表明气候变暖，这需要通过系统的未来测量来证明。和由单点和透明地震相识别的重力流，以及沉积物羽流贡献，在近端区域盆地形成层状相。这些沉积机制和地貌与潮湿的极地气候一致，但其中一些表明气候变暖，这需要通过系统的未来测量来证明。
