Paleoproductivity Variations in the Equatorial Arabian Sea
We analyzed a sediment core from the equatorial Arabian Sea, chronologically constrained by accurate accelerator mass spectrometry (AMS) radiocarbon dates on selected planktonic foraminiferal species, for paleoproductivity variations corresponding to the variations in the Indian Ocean Equatorial Westerlies (IEW). The IEW in turn are positively correlated to the Southern Oscillation Index (SOI), which is a measure of El Niño, Southwest monsoon (SW…
Changes in surface productivity and subsurface denitrification during the Holocene
Spatial and temporal variations in the intensity of subsurface denitrification in the water-column of the eastem Arabian Sea have been investigated using chemical and isotopic proxies. The data show a steady increase in the denitrification intensity from ∼10 ka to ∼2 ka BP, probably caused by changes in surface productivity fuelled by strengthening of upwelling (monsoonal intensity). In addition, changes in redox conditions and detrital material …

Earliest Acheulian Industry from Peninsular India
Geochronology of Palaeolithic cultures in the Hiran Valley, Saurashtra, India
Dating Indian Corals by U-Decay-Series Methods
Nine samples of corals collected from seven locations in the Saurashtra Coastal region of India were dated by 238 U series disequilibrium methods. Of the three age groups (6000, 30,000, and 120,000 yr) reported for this region by the earlier studies of S. K. Gupta and B. S. Amin (1974, Marine Geology 16, 79–83), we could confirm only the 6000-yr group. Instead of a 120,000-yr group, we found a scatter of ages between 118,000 and 176,000 yr. There…
Late Quaternary Faunal Change in Coastal Arabian Sea Sediments
Carbonate content and faunal composition of two gravity cores from the coastal Arabian sea provide evidence of a major environmental change in surface ocean waters about 13,000 yr B.P. Radiocarbon dating indicates that deposition rates ranged from 1.8 to 9.8 cm/10 3 yr, with a major change in rate occurring in one core at about 7500 yr B.P.
