Direct evaluation of sea-ice production and associated volume transport of Antarctic Bottom Water in a coastal region off the Antarctica

根据南极底水通道（AABW）中克尔盖伦高原东侧翼的系泊资料，揭示了该区域的南极底水赤道输送与威德尔海相当，是经向翻转环流的重要组成部分。利用Cape Darnley Polynya （CDP）的系泊数据，我们证实了该地区是在当地生产AABW的。我们成功地完成了CDP海冰厚度的系泊观测，获得了南极海岸冰裂带的首个高精度数据。

Based on the mooring data obtained off the eastern flank of the Kerguelen plateau in the pathway of Antarctic Bottom Water (AABW), we revealed that the equatorward transport of AABW in this region is comparable to that from the Weddell Sea and an important part of the meridional overturning circulation. Using the mooring data off the Cape Darnley Polynya (CDP), where sea-ice production is active, we confirmed that AABW is produced locally in this region. We have succeeded in the mooring observation of sea-ice thickness in the CDP and obtained the first high-precision data in the Antarctic coastal polynyas.
