Ocean Acoustic Tomography in the Greenland Sea

所提议的工作是 海洋声学数据的分析 格陵兰海断层成像的首席研究员 实验这项实验于1988-89年进行， 由一个五角形阵列组成， 第六个系泊在中心。 的 实验的目的是研究 格陵兰海深水区， 风应力和冰盖的变化，以及 声波能量在边缘冰区的传播。 在这个实验中获得的大数据集，以及 同时移动船舶层析成像测试，以及其他几个 海洋学研究，目前正在分析四个 学术机构 该项目不仅将改善 我们对深水形成和循环的理解， 但也是对声学应用的一个很好的测试 在确定海洋过程中的信息。

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.
