The CRP-3 core, drilled in western McMurdo Sound in October and November 1999, penetrated 823 m of lower Oligocene (to possibly upper Eocene) glacially influenced sediments. The palaeoclimatic record of CRP-3 is examined using major element analyses of bulk core samples of fine grained sediments (mu...

The CRP-3 core, drilled in western McMurdo Sound in October and November 1999, penetrated 823 m of lower Oligocene (to possibly upper Eocene) glacially influenced sediments. The palaeoclimatic record of CRP-3 is examined using major element analyses of bulk core samples of fine grained sediments (mudstones and siltstones) and the Chemical Index of Alteration (CIA) of Nesbitt & Young (1982, doi:10.1038/299715a0). The CIA is calculated from the molar abundances of Al, K, Ca, and Na oxides, and its magnitude increases as the effects of chemical weathering increase.
