If you are a scientist looking for a particular document, then your best option is to use one of the menu items located to your lower left. If you are not a scientist and are looking for an item that is of broad interest then you may wish to go first to the "press releases", "multimedia", and "walking on ice". If you don't find what you want over there, then you may wish to use the search engines on the left.

Cave Research

I am interested in the manner that the fresh water flows from the surface to the aquifer (which contains sinkholes, caves and tunnels), and from the aquifer to the rivers via the springs and ultimately to the ocean. In Florida, this happens in what is called a karstic environment, which is a system involving a maze of tunnels as well as regions containing the familiar porous media consisting of sand and clay.

This kind of medium was first found in Europe. Early on, the process was referred to by various names but, ultimately, the international scientific community has settled on karst, the German name for Kras, a region in Slovenia partially extending into Italy, where it is called "Carso" and where the first scientific research of a karst topography was made. This particular environment is created because over geological time, the ground water gradually dissolves the bed rock or limestone.

How the flow is divided between the traditional porous media and the tunnels is essentially unknown. This challenging field is relevant to only a few places around the globe. The most notables are some parts of Europe, The Yucatan and Florida.
