Fig. 9. Compilation of stable isotope records for
planktonic foraminifera ()
and benthic foraminifera (
)
showing long-term climate trends in the Atlantic and global ocean. Not all the
trends shown are strictly global as some, such as the mid-Maastrichtian
18O
increase in benthic foraminifera, are not observed in the Atlantic and others,
such as the various trends in Albian and Cenomanian time may include features
unique to the silled basins of the Atlantic. Early Albian data from ODP Hole
1049C (Blake Nose, western North Atlantic; Erbacher et al. 2000), late
Albian–early Cenomanian data from ODP Site 1052 (Blake Nose, western North
Atlantic; Norris and Wilson 1998), Cenomanian–early Turonian data from ODP
Hole 1050C (Blake Nose, western North Atlantic; Huber et al. 1999, unpubl.
data); latest Cenomanian data from DSDP Site 144 (equatorial western Atlantic;
Norris et al . unpubl. data); Turonian–early Campanian datasets from various
North Pacific DSDP sites (mostly DSDP Sites 463, 305 and 311 (Douglas &
Savin 1973, 1975, 1978; Barrera 1994)); Maastrichtian and late Campanian data
from DSDP Site 463 (equatorial Pacific; Barrera & Savin 1999); Palaeocene
data from DSDP Site 384 (northwest Atlantic; Berggren & Norris 1997), and
late Palaeocene and Eocene data from ODP Site 865 (north central Pacific;
Bralower et al., 1995).
