Near surface variations in mean annual microparticle concentration and oxygen isotope as a function of time
The Quelccaya Ice Cap in Peru (13°56'S; 70°50'W) has been the focus of a paleoclimatic and glaciological program since 1976 (Thompson, 1979; Thompson et al., 1984a). The central objective of the Quelccaya program was accomplished with the extraction of a 1500-year paleoclimatic record for...
