RECAP ice core d18O data from CFA measurements averaged in 5mm depth intervals.

Technical note on the MEM gap-filling methodology:The MEM infilled data have been generated using the Fahlmann and Ulrych (1982) MEM #interpolation scheme. The MEM infilling is carried out iteratively by first filling out the smallest gap in the #data, and then use progressively larger and larger data sections (connected by small infilled gaps) to infill larger and larger gaps in the data series. The AR order of the MEM infilling routine is adaptive (as it is limited by the length of the data sections without gaps used to calculate the AR coefficients), but the AR order #has nevertheless been capped at a maximum of500 irrespective of data availability.
