Study of sub-surface sediments from northern Indian Ocean: Oceanic responses to climatic changes
The mean diameter and variation in isotopic composition (delta sup(18)) in thest of Orbulina universa d'Orbigny have been measured in a sediment core collected from 3869 m water depth near the Carlsberg Ridge, northern Indian Ocean. It has been found that changes in test's mean diameter pr...
