海底：js345线路检测家探索海洋深处

阿伊达·法罗, js345线路检测地质学助教教授, 她在研究船上花了数周时间在海上研究海底, 水下火山和热液喷口. 在此视频中, 法罗讨论她在 U 上的工作.S. 称为 JOIDES Resolution 的研究钻探船. 视频由 JOIDES 决议提供.

  • The shrunken plastic foam cup with the Kansas State University Powercat on the right was once the size of the regular plastic foam cup on the left. During a research cruise, Aida Farough, a Kansas State University teaching assistant professor of geology, sent this cup to the bottom of the ocean — a depth of more than a mile — near Brothers volcano in the Pacific Ocean northeast of New Zealand. The underwater pressure caused the plastic foam cup to shrink and remain that way. | Photo credit: Aida Farough, Kansas State University

Farough was selected as one of 11 researchers from the U.S. for the two-month research cruise, which focused on Brothers volcano in the Pacific Ocean and marked the first attempt to drill into a submarine volcano. | Photo credit: Aida Farough, Kansas State University

堪萨斯州可能是内陆国家, 但这并没有阻止js345线路检测的地质学家继续前进1.水下 5 英里，探索太平洋最深处.

阿伊达·法罗, 地质学助教教授, 她在海上度过了数周时间，js345线路检测海底, 大洋中脊的水下火山和热液喷口. 但法罗的水下探索不仅仅帮助科学家了解海底的矿物质和微生物生命. 她的js345线路检测可以为地球上生命的起源以及其他行星上生命和热液喷口的存在提供重要见解.

“只是因为我们js345线路检测的后院没有海洋, 我们不应该忽视海洋和海洋的机会探索,”法鲁说. “我们对海洋的了解还不如对太阳系中某些行星的了解. 事实上, 我们拥有比美国部分海洋更好的火星地图.S. 领土.”

这就是法罗参与多个大型国际js345线路检测项目的原因，这些项目旨在更多地了解海底的地质过程.

在一次由国家科学基金会资助的大学-国家海洋学实验室系统js345线路检测巡航期间, 深深潜入太平洋底部 - 深度 2,500 米, 或大约 1.5 英里 — 乘坐载人车辆阿尔文. 法罗最近还在美国与国际海洋发现计划的科学家们一起度过了两个月.S. 称为“JOIDES 决议”的钻探船，旨在js345线路检测兄弟火山附近的矿产资源, 这是新西兰东北部太平洋克马德克弧上最活跃的火山.

js345线路检测的 Matthew Brueseke 等地质学家团队进行的一项新研究, 地质学副教授, 已发现位于阿拉斯加兰格尔-圣的兰格尔火山带. 埃利亚斯国家公园和自然保护区的历史比人们之前认识的要古老，这也决定了其火山场自形成以来一直持续活跃的原因.

这项js345线路检测产生了新的地球化学和地质年代学数据，涵盖了整个火山弧的形成过程. 结合之前js345线路检测的数据, 团队确定了火山带的年龄.

“新数据有助于证明js345线路检测岩浆作用至少在大约 3000 万年前开始, 比之前认识的要早几百万年,”布鲁塞克说.

该小组还确定，位置和几何形状与火山的持续活动和大小有很大关系. 这会创建一个允许增加岩浆量的环境, 然后它可以沿着断层向上穿过地壳并可能喷发.

兰格尔火山带是地球上一些高度和体积最大的火山的所在地, 包括至少两个历史上活跃且被美国视为危险的国家.S. js345线路检测调查.
