Ocean Acoustic Tomography in the Greenland Sea

拟议的工作是对格陵兰海洋层析实验首席研究员获得的声学海洋学数据分析的继续和总结。这项实验是在1988-89年间进行的，由五个声音收发机组成的五角形阵列组成，第六个停泊在中心。该实验的目的是研究格陵兰海深水的幕式形成，格陵兰海环流对风应力和冰盖变化的响应，以及边缘冰区声能的传播。在这项实验中获得的大量数据集，以及同时进行的船舶层析成像测试，以及其他几项海洋学研究，目前正在四个学术机构进行分析。该项目不仅将提高我们对深水形成和循环的了解，而且也是对声学信息在确定海洋过程中的效用的极好测试。

The proposed work is the continuation and conclusion of the analysis of acoustic oceanographic data obtained by the principal investigator in the Greenland Sea Tomography Experiment. This experiment, conducted during 1988-89, consisted of a pentagonal array of five acoustic transceivers with a sixth moored in the center. The goals of the experiment were to study the episodic formation of Greenland Sea Deep Water, the response of the Greenland Sea gyre to variations in wind stress and ice cover, and the propagation of acoustic energy in the marginal ice zone. The large data set obtained in this experiment, as well as a concurrent moving ship tomography test, and several other oceanographic studies, is currently being analyzed at four academic institutions. This project will not only improve our understanding of deep water formation and circulation, but is also an excellent test of the utility of acoustic information in defining oceanographic processes.
