Fun with Heloclines

We’ve got a lot of blogging to catch up on from this summer. But for now, here’s some pics from yesterday’s dive in Mexico in Cenote Naharon in Sistema Naranjal, just south of Tulum.

The section we spent a bunch of time in yesterday is right in the helocline, where “lighter” fresh water floats on top of denser salt water; the helocline is super pretty and produces a lot of cool effects with light and impacts the look of the cave decorations. Here’s some quick screen-grabs.


Over-under helocline shot – above is slightly tannic, formations stained, below is salt, and blue water and mostly white formations. Swimming pool affect.


The top of this formation is stained from being in the fresh tannic water, below stays white since in salt water.
