For nearly one hundred years geologists
have been drilling into ice to obtain detailed chemical records
of past atmospheres.
|
The majority of such drill cores are
from sites in Antarctica and Greenland, although there have been
samples obtained from glaciers |
in Wyoming (Upper Fremont Glacier), Peru
(Quelcccaya Ice Cap and Huascaran), Africa (Mt. Kilimanjaro),
China (Guilya Ice cap), |
Bolivia (Nevado Sajama), Tibet
(Eastern Rongbuk Glacier), Russia (notably the various glaciers
in the Altai in southern Russia) and |
Alaska (the St. Elias Mountains). The 1816 peak is from the
eruption of Mt. Tambora in Indonesia. The source for 1810 is
unknown. |
