Zusammenfassung |
Reliable age models are fundamental for any palaeoclimate reconstruction.
Available interpolation procedures between age control points are often
inadequately reported, and very few translate age uncertainties to proxy
uncertainties. Most available modeling algorithms do not allow incorporation
of layer counted intervals to improve the confidence limits of the age model
in question.
We present a framework that allows detection and interactive handling of age
reversals and hiatuses, depth-age modeling, and proxy-record reconstruction.
Monte Carlo simulation and a translation procedure are used to assign a
precise time scale to climate proxies and to translate dating uncertainties
to uncertainties in the proxy values. The presented framework allows
integration of incremental relative dating information to improve the final
age model. The free software package COPRA1.0 facilitates easy interactive
usage. |
