Measurement of organic carbon in polar snow samples
Glaciers provide a unique medium for the study of palaeoatmos-pheric chemistry1–3, particularly in polar glaciers where chemical records may extend for at least several hundred thousand years. Glaciochemical records from remote, high-latitude areas provide a regional- to global-scale integration of...
