Stable oxygen isotope ratios of the planktonic foraminifera Globigerina bulloides of ODP Hole 117-723A in the Arabian Sea (Table 2) ...
Oxygen and carbon isotopic analyses have been performed on the tests of Globigerina bulloides and Pulleniatina obliquiloculata (planktonic foraminifera) and Uvigerina excellens (benthic foraminifer) to study the evolution of surface and bottom water hydrographic changes associated with summer monsoo...
