DESCRIPTION:
This study looks for evidence of the carbonate ion effect (identified in 
laboratory experiments) on stable isotopes in foraminifera spanning a 
natural carbonate ion gradient at the equatorial Pacific.

The data set comprises size, weight, d18O and d13C data for two species
of planktonic foraminifera (G. ruber and P. obliquiloculata) collected 
in sediment traps along a transect spanning the equator along 140°W, 
from 5°N to 12°S (135°W).
