Scope
|
In order to reconstruct the Earth climate system, marine paleoclimatologists resort to transfer
functions or geochemical proxies, which are produced or affected by organisms. The relationships used for
reconstructions are generally based on field calibrations or derived from laboratory experiments. The danger of
these so called empirical relationships is that they maybe valid only within the restricted parameter space of their
calibration. Application of proxy relationships to very different environmental settings (e.g. high vs. low latitude or
glacial vs. interglacial) requires a mechanistic understanding of these relationships. Much progress can be
expected by a better understanding of the biocalcification mechanisms and the incorporation of proxy signals.
In this session we invite contributions related to the biocalcification, calibration and validation of marine proxies.
