A Search for Extraterrestrial Amino Acids in Polar Ice: A Progress Report

Fifteen polar ice samples-fourteen from Greenland and one from Antarctica-have been analyzed for the extraterrestrial amino acid alpha-aminoisobutyric acid (AIB) in an effort to estimate the flux of interplanetary organic material to the Earth's surface. Only one sample (Greenland GISP II, 4270...
