Hole made with drilling equipment.\n\n3. Any exploratory hole drilled into the Earth or ice to gather geophysical data. Climate researchers often take ice core samples, a type of borehole, to predict atmospheric composition in earlier years. See ice core.\n\n4. The hole in the earth made by the drill; the uncased drill hole from the surface to the bottom of the well.\n\n5. Any exploratory hole drilled into the Earth or ice to gather geophysical data.
