Automated ice-core layer-counting with strong univariate signals

Wheatley, J.J.; Blackwell, P.G.; Abram, Nerilie; McConnell, J.R.; Thomas, E.R.; Wolff, E.W.


We present an automated process for determining the annual layer chronology of an ice-core with a strong annual signal, utilising the hydrogen peroxide record from an Antarctic Peninsula ice-core as a test signal on which to count annual cycles and explain the Methods. The signal is de-trended and normalised before being split into sections with a deterministic cycle count and those that need more attention. Possible reconstructions for the uncertain sections are determined which could be used...[Show more]
