So I never knew this before, but apparently when seawater freezes, it forces salt out, thereby making the water surrounding it more saline. That starts a chain reaction with which you may be more familiar: the saline water has a lower freezing point and higher density, so as this super cold water freezes, it starts to sink away from the surface ice, creating an ice stalactite, otherwise known as a brinicle. But as David Attenborough explains, this is just the beginning:
I love how scientists have managed to figure out exactly why this happens...

You're probably familiar with the concept of the placebo effect: you pretend to provide some sort of treatment to a patient (sugar pill, saline shot, shaman chicken dance, homeopathic elixir, etc.), and because there is no actual medicine or treatment,...
- Nature's Great Events - The Great Melt
When the ice in the Arctic starts to melt as the sun rises in the sky, things begin to happen, life resumes its annual cycle, and David Attenborough is there to tell us all about it to the sight of some spectacular photography. Watch as polar bears come...

- Matrix Of "life Forms"
Maybe something can be learned from science fiction...not all life forms are carbon based and need water. "'Life as we don't know it' in the universe? Start with Titan" Saturn's frigid moon Titan is not a candidate for Earth-like life....
