Confusion of terms
There have been two international papers recently, which have
misused or abused the term 'normalization'. At least since
Gonfiantini (1978) in NATURE 271, 534-536, there are two modes of
adjustment of a stable isotope delta scale. One is the exact
setting of zero (zero shift) and the other, scale normalization.
Scale normalization involves two isotopically very different
reference materials and effectively sets or normalizes the size
of the delta permil unit. The zero shift is more trivial, but no
less important. Clearly the Oxford or Webster Dictionary will not
tell us the difference, but confusing these terms will begin to
undo the tremendous progress made in the last few years with the
reporting of stable isotope data.
Thanks, and cheers from New Zealand.
