Funds are provided to support field research and analysis that will begin to develop an understanding of the dynamics and properties of the deep waters of the Canada Basin. The work builds on preliminary deep mooring observations near 2500-m depth that suggest a dynamically active environment in these deep waters, not the quiet basin previously assumed. The aim of the proposed work is to observe the horizontal and vertical motion in the deep Canada Basin over one year. To this end, the co-PIs will add instruments to the deep portion of two moorings that are scheduled to be deployed in the Canada Basin for one IPY year (2007-2008). The additional instruments will record velocity, pressure, temperature, and salinity below 2200 m. These will provide long time-series measurements in the deep Canada Basin, and will be a vital component of the "snapshot in time" of the state of the Arctic Ocean between 2007 and 2009.

提供资金支持实地研究和分析，开始了解加拿大盆地深层沃茨的动态和特性。 这项工作建立在2500米深度附近的初步深水系泊观测的基础上，该观测表明这些深水沃茨中存在动态活跃的环境，而不是先前假设的安静盆地。 拟议的工作的目的是观察水平和垂直运动在深加拿大盆地超过一年。 为此，共同项目研究所将在计划在加拿大海盆部署的两个系泊系统的深部增加仪器，为期一个国际年（2007-2008年）。 增加的仪器将记录2200米以下的速度、压力、温度和盐度。 这些将提供加拿大海盆深处的长期时间序列测量，并将成为2007年至2009年期间北冰洋状况“时间快照”的重要组成部分。
