1999-2000年冬季估计形成了8.6 - 10 12立方米的DSW，平均年产量为0.3 Sv。根据直接观测，这一时期的DSW出口率从秋季的微不足道到冬季（1 - 2月）的0.75±0.27 Sv，再到春季（3 - 4月）的0.34±0.12 Sv。根据这些观测，平均年出口率可估计为0.27希沃特。用于获得积分估计的相同关系也采用了不同的方法，使用平流方法结合实际的流动和热通量场，从而可以与系泊观测结果进行直接比较。这一对比突出了沿陆架平流和跨陆架涡旋输送对DSW形成的精确参数化的重要性。索引条款：4207海洋学：一般：北极和南极海洋学；4540海洋学：物理：冰力学和空气/海洋/冰交换过程；海洋学：一般：水团；海洋学：一般：大陆架过程；
an estimated 8.6 � 10 12 m 3 of DSW was formed during the winter of 1999–2000, resulting in a mean annual production rate of 0.3 Sv. According to direct observations, the export rate of DSW during this period varied from negligibly small in autumn to 0.75 ± 0.27 Sv in winter (January–February), to 0.34 ± 0.12 Sv in spring (March–April). From these observations the mean annual export rate can be estimated to be 0.27 Sv. The same relationships used to obtain the integral estimates were also applied differentially using an advective approach incorporating realistic flow and heat flux fields, which allowed direct comparison with the moored observations. The comparison highlights the importance of along-shelf advection and cross-shelf eddy transport to the accurate parameterization of DSW formation.
