中文摘要
小行星9314632 专业研究员过去曾参与海洋大气署在JdF东侧基底高点三个热液地点的巡航(即FlankFlux '90,' 92),这使他提出了一个热液过程如何在脊侧翼运作的模型。 在本项目中,PI将与ALVIN一起返回,并进行一些空间精细尺度的观测,测量(热流,水柱特性等), 收集样本来评估他现在的模型 研究所认为,过去在若干不同地点对海脊侧翼热液喷口进行的研究表明,热液过程及其影响各不相同;因此,有必要进行拟议的这类描述性研究,以确定海脊侧翼热液循环的全球影响。 选定的地点是“JdF-3”,它提供了一个独特的机会,具有高沉积速率和高基底温度,通常,这种小型分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 . ***
