They have a similar structure to ice crystals, enabling them to act as a seed to start the ice-crystal formation process. Researchers documented 18 abrupt climate events. In many locations in Antarctica the air temperature is always well below the freezing point of water. One egg will go to the EGRIP site in northeast Greenland where a 2.5km-long ice core is being drilled.

Ice cores are cylinders of ice drilled out of an ice sheet or glacier. Slices of ice core, drilled from the depths of the Earth’s ice sheets, reveal details of the planet’s past climate. When snow falls it traps air into the ice. “Ice nucleators are molecular mimics of ice,” says Barnes. Introduction. If the summer temperatures do get above freezing, any ice core record will be severely degraded or completely useless, since meltwater will percolate into the snow.
