Description:
We present a method for determining the
δ180 of seawater in the deep ocean during the last
glacial maximum from the measured δ180 values
of deep sea pore fluids. Using data from Deep Sea
Drilling Project (DSDP) site 576 in the Western
Pacific, this method yields a glacial to interglacial
change in δ180swof 1.010.25 0/00. This value for
~δ180sw is the first direct measurement of deep
ocean 8180 for the last glacial maximum and
avoids the problems of spatial and temporal
variability of the δ180 of surface water implicit in
previous determinations. More precise, higher resolution
pore fluid measurements are required to
improve this determination.
