布兰斯菲尔德海峡是位于西南极半岛地区北方的一个半封闭海,气候变化剧烈。水深复杂,由三个盆地组成,彼此被浅岩床隔开。自二十世纪上半叶以来,就有关于布兰斯菲尔德海峡区域的海洋测量数据。在本研究中,提供了2013年RVPolarsternin ANT-XXIX/3探险的水文数据,以描述最新的实际物理状况,特别是在该航行期间完成的生物工作。2013年布兰斯菲尔德海峡的总体水文状况与世纪初的观测结果相似。布兰斯菲尔德海峡的水团是邻近海域水团的改良版本。布兰斯菲尔德海峡内的不同水团被两个锋面分开,即所谓的布兰斯菲尔德锋面和半岛锋面。虽然布兰斯菲尔德锋在布兰斯菲尔德海峡的中部和西南部最为明显,但半岛锋可以从研究区域的东北部到中部识别。根据对南极半岛周围和靠近南极湾的水团特性的分析,从威德尔海通过南极湾的陆架水的显著流入似乎是不可能的。
The Bransfield Strait is a semi-enclosed sea located in the northern part of the West Antarctic Peninsula region, which is subject to strong climatic changes. The bathymetry is complex and comprises three basins that are separated from each other by shallow sills. Oceanographic measurements of the Bransfield Strait region are available since the first half of the twentieth century. In this study, hydrographic data from the ANT-XXIX/3 expedition of RVPolarsternin 2013 are presented to describe the actual physical state of the art, particularly for biological work done during that cruise. The general hydrographic situation of the Bransfield Strait in 2013 is found to be similar to observations from the early twentieth century. The Bransfield Strait’s water masses are modified versions of the water masses from the adjacent seas. The different water masses within the Bransfield Strait are separated by two fronts, the so-called Bransfield and Peninsula Front. While the Bransfield Front is most pronounced in the central and southwestern Bransfield Strait, the Peninsula Front can be identified from the northeastern to the central part of the study domain. Based on an analysis of water mass properties around the Antarctic Peninsula and close to the Antarctic Sound, a notable inflow of Shelf Water from the Weddell Sea through the Antarctic Sound appears unlikely.
