Abstract	Spectral analysis techniques traditionally applied to proxy climate records have involved the use of specialized windowing functions because of the finite length of the record available. These have the effect of artificially broadening the spectral peaks such that closely spaced peaks may not be fully resolved. Alternatively, use of a simple “boxcar” window following Muller and MacDonald [1997b] will maximize the spectral (frequency) resolution. This is achieved at the expense of potential truncation artifacts (manifested as “spurious” peaks in the spectra), although in the spectral analyses presented here, such additional peaks are not significant. In addition, simple methods like this are not able to place any confidence intervals on the results. Global ice volume proxy records obtained
