I'm not familiar with Mallorca's hydrogeology, but I've done some cenote (cavern) diving in Mexico's Yucatan peninsula. The caves are inland, but sea water infiltrates through the porous and channel-filled rock. The water nearer the surface is rainwater.
The narrow region where freshwater and seawater intermingle is called the halocline, it creates a cool optical distortion which reminds me of the "oil paint" filter in photoshop.
- stingraycharles 9y agoThis probably is a stupid question, but wouldn't the salty seawater be lighter than the rain water, and thus be at the surface ?
- cr1895 9y agoSalty water is quite literally more dense than fresh water. Average seawater is 1025 kg/m^3, pure water is nominally 1000 kg/m^3.

- stingraycharles 9y agoOh geez, you're absolutely right, I don't know what I was thinking. I probably needed my morning coffee.
- x2398dh1 9y agoIt's OK, stingrays like you aren't expected to know about polar regions and super cold water.
