Oceanography doctoral candidate Jeff Bowman said:

“Although frost flowers are very abundant in the Arctic and Antarctic getting to them isn’t easy.  The ice underneath them is often too thin to walk across and prone to drifting with the wind.  The basic sampling strategy is to find a place where the water is kept open by winds or currents.”

According to Deep Sea News, these delicate Ice Flowers can only form under very special conditions.

“-Calm winds. We can’t have these beauties blown away can we?

-Cold, cold air. It has to be about 20C less than the water and since seawater freezes around -2C, that means the air must be about -22C or -7.6F.”
