core sampling
Subsurface cylinder retrieval
Core sampling is a technique for extracting a cylindrical cross-section from a material—soil, ice, rock, or sediment—to examine its composition and layers.
A hollow drill cuts into the material and retrieves a core that preserves the vertical sequence: Ice core sampling in Antarctica reveals climate data going back hundreds of thousands of years.
The method is essential in geology, archaeology, and environmental science.
