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

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.
