Cochin backwaters: An introduction to the system, prior studies, historical trends and future implication
(Kalpana Corporation, Varanasi, India, 1994)Studies over the last 2 decades in the Cochin backwater system in India are reviewed to have an integrated profile with a point to evaluate future development projects in terms of potential consequences to the estuarine ... -
Implication of coastal refineries to the ecology of the Gulf of Kachchh
(Soc. of Ocean Sci. and Technol., New Delhi, India, 1994)In order to meet the projected demand of petroleum products it is essential to establish additional refining capacities to process imported crude. Two grass root refineries with a combined capacity to process 24 MMTPA are ... -
Pollutant dispersion studies - An update on the problems in Indian coastal waters
(Indian Inst. of Technol., New Delhi and NIO, India, 1994)Pollutant dispersion problems along the Indian coastal waters are characterisEd. by site-specificity, as a result of seasonal and physiographic variabilities. Presence of large rivers, estuaries and backwaters add to the ... -

Influence of geomorphological and tectonic control in the mineralization of the western shelf of India
(S.R. Rawat Publ., New Delhi, 1994)The west coast of India has two kinds of coastal rocks predominantly of Deccan basalts in the north and granitic and gneissic in the south, each similar in bulk composition. It is indeed peculiar to notice only two types ... -
Analysis of space-borne data for coastal zone information extraction of Goa Coast, India
(Elsevier, 1994)Space-borne data covering the coastal zone of Goa State were processed using digital and visual image-processing techniques to extract information about the coastal zone. Digital image processing of thematic data included ... -
A new design concept for nodule mining system
(Publ. and Inf. Dir., New Delhi, India, 1994)An overview is presented on the hazards associated with various types of equipment to be used for the commercial mining of nodules from the seabed. The design of a suitable mining collector and the various options available ... -
An application of the multibeam sounder for seabed backscattering analysis
(Ultrasonics Society of India, 1994)A theoretical analysis of vertical farfield pattern for a multibeam sounder is performed. The farfield pattern for different steered angles establish the usefulness of present multibeam arrays. An interaction effect of ... -

Technological challenges for manganese nodule mining
(Publ. and Inf. Dir., New Delhi, India, 1994)The major technological challenges of deep-sea mining venture involve delineation of mine site and development of mining technology to bring out the minerals from extreme conditions (more than 5 km water depth, 0-3 degrees ... -
Development of manganese nodule resources in the Central Indian Ocean
(Japan Shipbuilding Industry Foundation, 1994)Resources evalution on grade and abundance of nodules using statistical methods for grab samples and photography data, combined with bathymetric and structural mapping, were carried out for delineation of the potential ... -
Relationship between size and geochemistry of polymetallic nodules from the Central Indian Ocean Basin: Significance in selection of high grade nodules
(Publ. and Inf. Dir., New Delhi, India, 1994)Morphological, mineralogical and geochemical studies on nodules of different sizes collected from the Central Indian Ocean Basin (CIOB) show two suits of nodule formation by oxic diagenetic and hydrogenous process resulting ... -
Seafloor mapping of large areas using multibeam system - Indian experience
(1994)To identify unproductive and difficult terrains, a detailed picture of the seafloor was essential. Hence, the area was resurveyed using the multibeam system hydrosweep during 1990-93. A total of 300,000 sq.km area has been ... -
Geotechnical properties of two siliceous cores from the central Indian Ocean
(CWPRS, Pune, 1994)Physical properties of the siliceous sediments from the Central Indian Basin are measured on two short cores. The properties such as water content, Atterberg limits, porosity specific gravity, wet density show the medium ... -
An observation of distribution features of cobalt rich manganese deposits
(Japan Shipbuilding Industry Foundation, 1994)Evaluation of seafloor stereo photographs, video data, and large diameter gravity core samples shows a variety of surface features associated with the crusts, nodules, and sediments covering mid Pacific seamounts. A set ... -
