Effect of exposure angle on the marine atmospheric corrosion of mild steel
(Sci. Surv. England, UK, 1996) -
Some observations on use of siliceous mineral waters in reduction of corrosion in RCC structures
(Metal Finishers' Association of India, 1996)The corrosion-resisting characteristics of reinforcement in cement blended with siliceous mineral wastes viz. gold tailing and flyash have been evaluated by using an accelerated corrosion technique. The additions of these ... -

Trade routes and communication pattern of ancient Orissa
(Harman Publishing House, New Delhi, India, 1996)Since the dawn of civilization in India, Indians have shown the interest in trade. The morphological features of India enabled to carryout overseas and land route trade smoothly. The evidences of trade in India is dated ... -
Evidence for hydrothermal activity in the Andaman Backarc Basin
(Current Science Association, Bangalore, India, 1996)Multibeam bathymetric, magnetic, gravity and seismic surveys revealed a complex morphotectonic fabric of the Andaman Backare Basin with a spreading ridge, several seamounts and faults. The ridge trending SW-NE direction ... -
Quantitative radiolarian assemblages in surface sediments from the central Indian Basin and their paleomonsoonal significance
(Geological Society of India, 1996)The percentage data of 47 radiolarian coarser taxonomic groups in the surface sediments from the central Indian Basin was subjected to cluster and factor analyses. The R-mode cluster analysis resulted in 3 dominant clusters ... -
Signatures of rare-earth elements in banded corals of Kalpeni atoll-Lakshadweep archipelago in response to monsoonal variations
(NISCAIR, CSIR, 1996)Concentrations of rare-earth elements (REE) have been determined in seasonal bands of Porites species collected from the Lakshadweep lagoon. Total REE (REE) are very low (less than 3 ppm) in these corals. Seasonal variations ... -
Heavy mineral distribution in the surficial sediments from the eastern continental margin of India and their implications on palaeoenvironment
(Indian Society of Earth Sciences, Calcutta, 1996)Heavy mineral distribution from the surficial sediments of the Eastern Continental Margin of India, between Machilipatnam and Gopalpur shows that their concentration ranges from 0.4 to 13.9%. Heavy minerals such as opaques, ... -
Geotechnical properties of marine soil off north Konkan Coast
(Allied, Chennai (India), 1996)Construction of any coastal structure requires detailed investigations on the environmental parameters as well as on the foundation soil. Preliminary geotechnicla investigations on the seabed sediment leads to a qualitative ... -
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 ... -
