Limeburner The variability of the inflow of Antarctic Bottom Water (AABW) into the North Atlantic will be investigated by deploying three, low cost, deep current meter moorings for 4 years. The site will be at the equator in the Western basin of the Atlantic where a two-year record show a possible warming trend accompanied by a decline in AABW transport. The primary scientific question is to determine whether this trend is real and associated with long-term changes in circulation of the North Atlantic.

南极底水（AABW）流入北大西洋的变异性将通过部署三个低成本的深流计系泊进行为期4年的调查。该地点将位于大西洋西部盆地的赤道，那里两年的记录显示可能出现变暖趋势，同时AABW输送减少。主要的科学问题是确定这种趋势是否真实，是否与北大西洋环流的长期变化有关。
