Growing need to study foraminifera in the laboratory culture experiments: An attempt from the central west coast of India
(K.D. Malaviya Institute of Petroleum Exploration, Dehra Dun (India), 1996)In recent past much emphasis has been laid on the high resolution reconstruction of the paleoclimatic conditions to help in preparing the futuristic climatic model. Many such efforts have used foraminifera as proxy indicators ... -
Seasonal changes of the sediment size distribution and stability along the beaches of Kerala, south west coast of India
(NISCAIR, CSIR, 1996)Mean grain size distribution under different environmental conditions along the coast of Kerala showed considerable spatial variation (0.14-0.96 mm). Standard deviation values indicated a very well sorted class along all ... -
sup(234) Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, Bangalore, India, 1996)We have determined the particle scavenging rates, export fluxes of sup(234) Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
Aeolian deposition of Arabia and Somalia sediments on the southwestern continental margin of India
(Current Science Association, Bangalore, India, 1996)Kaolinite, smectite, illite and chlorite as major clay minerals and palygorskite and gibbsite in minor quantities have been recorded from the slope of southwestern continental margin of India. Contribution of kaolinite, ... -
India's manganese nodule mine site in the Central Indian Ocean
(Current Science Association, Bangalore, India, 1996)This commentary highlights the activities of massive exploration programme for manganese nodule deposits in the Central Indian Basin located 5 km below the ocean surface and India's claim for mine site development and ... -
Sedimentological and clay mineral studies in Kakinada Bay, east coast of India
(NISCAIR, CSIR, 1996)The sediments of Kakinada Bay are predominantly silty clays, with a phi mean range between 2.9 to 7.8 northern, central and southern parts of the bay consist of finer sediments (5.5 to 7.05 phi) while the eastern and western ... -
Ablated tektite from the central Indian Ocean
(Meteoritical Society, Fayetteville, USA, 1996)A well-preserved ablated (button-shaped) tektite recovered from the surface sediments of the central Indian Ocean lacks flow ridges and has apparently undergone ablation of 6.9 to 7.9 mm. The lack of flow ridges and amount ... -
Marine mineral resources of the Central Indian Basin: Ferromanganese nodules and crusts
(Gulf Pub., Houston, USA, 1996)The morphology, mineralogy and composition of ferromanganese nodules and crusts from the Central Indian Basin and southwestern flank of the Charlsberg Ridge have been characterized from the analyses of data and samples ... -
Seasonal variability of the vertical fluxes of Globigerina bulloides (D'Orbigny) in the northern Indian Ocean
(University of Hamburg, 1996)Settling particles intercepted using time-series sediment traps at seven locations in the northern Indian Ocean have been examined for the spatial and temporal variability in the distribution and fluxes of Globigerina ... -

(University of Hamburg, 1996)Settling particles intercepted using time-series sediment traps at seven locations in the northern Indian Ocean have been examined for the spatial and temporal variability in the distribution and fluxes of Globigerina ... -
Origin of amphibole-rich beach sands from Tila-Mati, Karwar, central-west coast of India
(Geological Society of India, 1996)The pocket beach at Tila-Mati, Karwar, central west coast of India, is characterised by the occurrence of amphibole-rich (chiefly tremolite-actinolite) coarse sand in the zone of minimal impact of waves and currents. In ... -

A 27,000 year record of Red Sea outflow: Implication for timing of post-glacial monsoon intensification
(American Geophysical Union, 1996)The history of the Red Sea Outflow (RSO) over the past 27,000 years from an AMS sup(14) C-dated high-resolution Delta sup(13) C record of benthic foraminifera from the inner Gulf of Aden assuming the dominance of circulation ... -
Australasian microtektites from the Central Indian Basin: Implications for ejecta distribution patterns
(Current Science Association, Bangalore, India, 1996)Microtektites belonging to the Australasian tektite strewn field have been recovered in one (SK-16/176) out of three cores examined from the Central Indian Basin. The microtektites have been identified based on their ... -
Phosphorite concretions in a sediment core from a bathymetric high off Goa, western continental margin of India
(Current Science Association, Bangalore, India, 1996)A sediment core collected from a bathymetric high off Goa on the western continental margin of India, has yielded phosphorite concretions with an average Pd2O5 content of 32.75%, the P2O5 concentrations being highest ever ... -
Submarine terrace limestones from the continental slope off Saurashtra-Bombay: Evidence of Late Quaternary neotectonic activity
(Current Science Association, Bangalore, India, 1996)Bathymetric and shallow seismic data from the continental slope off Saurashtra-Bombay indicate wide submarine terraces at 130, 145 and 170 m and reefal structures at 320-360 m water depths. 10 cm thick slabs of limestones ... -

Evidences of late quaternary neotectonic activity and sea-level changes along the western continental margin of India
(Current Science Association, Bangalore, India, 1996)The offshore data on sea-level changes along the western margin of India have been reviewed and evidences of Late Quaternary neotectonic activity and subsidence are documented, based on the diagenetic textures of limestones ... -
Distribution of foraminifera in the Cochin estuary
(Marine Biological Association of India, 1996)A total of 78 foraminiferal species have been identified from sediment samples collected from the estuarine area of Cochin during faunal surveys representing different seasons. Abundance and toatl number of species (live ...
