The fate of sand dunes of Goa
(International Ocean Institute, Madras, India, 1996) -
Gas-charged sediments in shallow waters off Redi along the central west coast of India
(Current Science Association, Bangalore, India, 1996)This study reports the occurrence of gas-charged sediments in the nearshore areas of the west coast of India. High resolution shallow seismic reflection profiles on the nearshore area along central west coast of India, at ... -
1300 km long late Pleistocene-Holocene shelf edge barrier reef system along the western continental shelf of India: Occurrence and significance
(Elsevier, 1996)A detailed analysis of echosounding and side-scan sonar data collected from the western continental margin of India has revealed the presence of prominent shelf edge reefs, concentrated mostly on the central and the southern ... -
Potentiality of foraminifera in deciphering paleo-sea levels
(Omega Scientific Publishers, New Delhi, India, 1996)Recently, the quest for paleo-sea levels during the Holocene became intense because of their use in developing accurate predictive models in connection with the accelerated sea level rise associated with the greenhouse ... -
Onset of an arid climate at 3.5 ka in the tropics: Evidence from monsoon upwelling record
(Current Science Association, Bangalore, India, 1996) -
Impact microcraters on an Australasian microtektite
(Meteoritical Society, Fayetteville, USA, 1996)Microcraters attributable to impact have been discovered on an Australasian microtektite from a core in the Central Indian Basin. The craters resemble lunar microcraters and those generated during impact experiments. The ... -
Record of the Cretaceous magnetic quiet zone in the distal Bengal fan and its significance in understanding the evolutionary history of the northeastern Indian Ocean
(Assoc. of Explor. Geophys., Hyderabad, India, 1996)The Bengal Fan was one of the thickest sedimentary basins of the World. Many were of the view that the magnetic anomalies will be hard to find off East Coast of India due to this huge sediment accumulation. Though extensive ... -
Foraminiferal fauna from the Cochin backwaters: Biological indicators of man-made changes in the environment
(K.R. Publishers, Udaipur, 1996)Sixty foraminiferal species belonging to 38 genera and 23 families have been recorded from grab sediments of the Cochin backwaters. Of all the species Ammonia baccarii is the most dominant and successful form in the throes ... -
Acoustic basement: Its relevance to Karwar port development
(Allied, Chennai (India), 1996)Detailed bathymetric, side-scan sonar and shallow seismic surveys followed by sediment sampling were conducted in Karwar Bay, Karnataka, India to study the surficial geology with special emphasis on basement configuration ... -
Potential distribution of subsurface methane in the sediments of the eastern Arabian Sea and its possible implications
(American Geophysical Union, 1996) -
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 ... -
