后这个问题——< a href = " //www.hoelymoley.com/questions/4466/source-of-water-for-the-great-artesian-basin-in-australia " >大自流盆地的水来源在澳大利亚< / >想知道是否有任何水下岩石管道运输淡水在海洋世界。我没有遇到任何搜索,但也许确实存在,我不知道。

从纯假设的角度来看,很可能一个水下含水层可以携带淡水海洋环境下。盐水更密集的淡水会渗入含水层和取代的淡水。盐水侵入全球沿海地区淡水含水层是这种行为的证据。 但不可能的情况下为你的水下岩石管道可能是密封承压含水层有明显的压力梯度(也许是石灰石、白云石界页岩)的源附近的山脉被海水淹没在一个山谷之中。

我必须承认,我对此事不了解海外含水层之前阅读此线程。通常当我想到水的水文模型,我认为作为一个系统的动态组件(雪、溪流、水分、冰川)和不一定老水口袋有点困深(目前没有知道明显的输入/输出系统)。符合这些< a href = " http://www.eoearth.org/view/article/153627/ " > < / >经典水文循环模型。

I searched a bit and found this paper on physorg.org which led me to other reads on the matter.

Apparently there is substantial offshore freshwater aquifers, trapped undersea. Water from Pleistocene, which probably got trapped during the glaciations, while the mean sea level was much lower. When the ice sheet (ex: Laurentidian) receded, sea level rose and freshwater in charged aquifers would be somewhat trapped and sealed. Multiple glaciation during the Pleistocene would have enabled the process to cycle multiple time during the last 2.5 M year.

And yes - the related paper in Nature specify that some of those 30 inventoried undersea aquifers have an onshore connection (Perth among others is listed there).

This is pretty interesting but in my opinion there is not a ton of paper on the question. Yet I will keep this part of this (paleo!) hydrologic cycle in mind when such questions and discussions arise in the future.
