Figure
8. Contour
map of the oxygen isotopic composition of the pore waters shown in meters below
seafloor, Sites 1003-1007. Sites 1005 is located on the right side of the figure
and is closest to the platform margin, whereas Site 1006 is located 25 km from
the margin. The heavy 18O
values close to the platform reflect the increasing amount of carbonate
diagenesis taking place in this region.
