摘要：A number of scientists have already warned against the risks of interpreting paleoclimate records without an adequate understanding of the diffusion of relevant chemical traces in deep ice cores (Gow, 1971; Ikeda and others, 1999; Bender, 2002; Faria and others, in press, and references therein). Particularly critical is the formation – either prior to drilling or during ice-core storage – of micro-inclusions such as solid inclusions, microscopic bubbles and plate-like inclusions (PLIs).
