Adaptive Filters in Paleoclimatology: Measure it Twice!

Time series of stable isotopes (oxygen, carbon) measured at foraminifers are often very noisy due to the combined effect of low sedimentation rates, intensive bioturbation and small sample sizes (5-20 foraminifers). Adaptive filters may help to increase the signal-to-noise ratio of such time series where conventional methods such as fixed fitters cannot be applied if optimal filtering is to be achieved, because the signal-to-noise ratio is unknown and varies with time.
