中文摘要
9314632主要利益攸关方过去参加了日本国防军东侧地下室高地的三个热液地点(即FlankFlux‘90,’92)的海洋和大气层管理局巡航,这促使他提出了一个关于热液过程如何在海脊侧翼运行的模型。在本项目中,PI将与阿尔文一起回去,进行一些空间精细的观测、测量(热流、水柱性质等),并收集样本以评估他目前的模型。PI认为,过去对一些不同地点的脊侧水热喷口的研究表明,水热过程及其影响是不同的;因此,有必要进行所提议的这类描述性研究,以确定脊侧水热环流的全球影响。所选择的地点是JDF-3,这为高沉积速率和高基岩温度提供了独特的机会,通常情况下,这样的小扩散热液喷口很难在未沉积的地区找到。***
英文摘要
9314632 Mottl The PIs past participation on NOAA cruises at three hydrothermal sites on basement highs on the eastern flank of JdF (namely, FlankFlux `90,'92) led him to propose a model of how hydrothermal processes operate at flanks of ridges. In the present project, the PI will go back with the ALVIN and make some spatially fine-scale observations, measurements (heat-flow, water column properties etc.), and collect samples in order to evaluate his current model. The PI argues that past work on ridge flank hydrothermal vents at a number of different sites revealed that the hydrothermal processes and their effects are diverse; and therefore, descriptive studies of the kind proposed are necessary in order to determine global impact of ridge flank hydrothermal circulation. The site chosen is "JdF-3" which provides an unique opportunity in having high sedimentation rate combined with high basedment temperature normally, such small diffuse hydrothermal vents would be difficult to locate in unsedimented areas . ***
