Jääkairauksen

Jääkairaus, a Finnish term, refers to the process of drilling through ice. This technique is commonly employed in a variety of contexts, primarily for scientific research, ice fishing, and rescue operations. In scientific research, ice cores are extracted using specialized ice drills to study past climate conditions, atmospheric composition, and geological history. These cores provide invaluable data for understanding long-term environmental changes.

For ice fishing enthusiasts, a hand-held or powered ice auger is used to create holes in frozen lakes or rivers, allowing access to the water below for fishing. The diameter and depth of the hole depend on the type of fish targeted and the thickness of the ice. In emergency situations, such as when a person or vehicle has fallen through ice, ice drills can be used to create anchor points for ropes or to widen existing openings for rescue. Safety is paramount in all forms of jääkairaus, with careful assessment of ice thickness and stability being crucial before any drilling begins. Different types of drills exist, ranging from manual augers to powerful motorized units, each suited to specific conditions and purposes.
