Reduced advection into Atlantic Ocean deep eastern basins during last glaciation maximum
WB Curry, GP Lohmann - Nature, 1983 - nature.com
Causes of change in deep water δ13C can be either global or local in extent. Global causes
include (1) climatically-induced changes in the amount of terrestrial biomass which alter the …

Geochemical evidence for suppression of pelagic marine productivity at the Cretaceous/Tertiary boundary
The normal, biologically productive ocean is characterized by a gradient of the 13C/12C
ratio from surface to deep waters. Here we present stable isotope data from planktonic and …
