The bulk chemistry of mudrocks in Ross Sea drillcores on the Antarctic inner shelf is re-evaluated to extract records of continental paleotemperatures and ice extent. The chemical index of alteration (CIA) of the sedimentary sequence derived from the composite of the Cape Roberts cores changes in ac...
