Air entrapped in bubbles of cold ice has essentially the same composition as that of the atmosphere at the time of bubble formation. Measurements on ice core samples from Byrd Station (Antarctica) and Dye 3 (Greenland) show that the atmospheric methane concentration was only about 350 parts per 109 by volume (p.p.b.v.) during the last glaciation, compared with a mean preindustrial level of about 650 p.p.b.v. and a present value of 1,650 p.p.b.v.
