Geomorphology of Goa and Goa Coast. A review
(Museo Geologico di Bologna, 1993)This review on the geomorphology of Goa and the Goa coast included studies on the interpretation of LANDSAT images, aerial photographs and extensive field work. Physiographically the region can be broadly classified into: ... -
Gas-charged sediments on the inner continental shelf off western India
(Elsevier, 1993)High resolution seismic reflection profiles on the inner continental shelf (less than 60 m water depth) off India from 10 degrees N to 22 degrees N show 5-35 m of weakly stratified acoustically transparent clays. At water ... -
Seasonality and interannual variability of particle-fluxes to the deep Arabian Sea
(Pergamon, 1993)Long-term sediment trap studies have been carried out since 1986 at three locations in the western, central and eastern Arabian Sea. Total and bulk component fluxes measured for 3 years at the central station and for 4 ... -
Polymetallic nodule resources of the Indian Ocean
(Offsetters, New Delhi, 1993)The seabed resources are large and varied and considerable knowledge and technological development are required to exploit them economically. Beyond the Exclusive Economic Zone (EEZ), the deposits which are of utmost ... -
Petrology of tectonically segmented Central Indian Ridge
(Current Science Association, Bangalore, India, 1993)Distribution and mineralogy of various rock types along the 4200-km-long slow-spreading Central Indian Ridge, between Owen fracture zone in the north and Indian Ocean triple junction in the south, is studied in the light ... -
Some aspects of microfouling and corrosion of materials in the tropical marine environment
(University of Hamburg, Germany, 1993)Microfouling material developed on aluminium panels after immersion in estuarine, coastal, shelf and oceanic waters was analysed for various biological, chemical and biochemical parameters. A single steps scraping with ... -
Verdine and other associated authigenic (glaucony, phosphate) facies from the surficial sediments of the southwestern continental margin of India
(Elsevier, 1993)Green grains, pale green-brown infillings of foraminifer tests and brown friable aggregates occur in the coarse fraction of the surface sediments from the southwestern continental margin of India, between the Periyar River ... -
Multibeam bathymetric, gravity and magnetic studies over 79 degrees E fracture zone, central Indian basin
(American Geophysical Union, 1993)A regional scale bathymetric map has been constructed for the 79 degrees E fracture zone (FZ) in the Central Indian Basin between 10 degrees 15'S and 14 degrees 45'S lat. and 78 degrees 55'E and 79 degrees 20'E long. using ... -
Exploring the oceans- The geophysical way
(Current Science Association, Bangalore, India, 1993)The evolution of the eastern continental margin of India (ECMI), the Bengal Fan and the Central Indian Basin (CIB) is a consequence of the breakup of India from the eastern Gondwanaland in Late Jurassic to Early Cretaceous. ... -
A note on sulphide-oxide mineralisation in Carlsberg Ridge basalts
(Geological Society of India, 1993)Pillow basalts from the Carlsberg Ridge at 3 degrees 35'N contain disseminated chalcopyrite, pyrite, and magnetite. The euhedral shape of the pyrite grains indicate them to be early formed and grown unobstructed while ... -
Bathymetric study of the Neotectonic Naini Lake in outer Kumaun Himalaya
(Geological Society of India, 1993)The Naini Lake is a product of rotational movement on a NW-SE trending Nainital Fault, quite after the establishment of the drainage of a mature stream named Balia Nala. Detailed bathymetric study, permits division of this ... -
Coexistence of pumice and manganese nodule fields-evidence for submarine silicic volcanism in the Central Indian Basin
(Pergamon, 1993)Pumice, of various shapes and sizes, uncoated or coatEd. by ferromanganese oxides, have been recovered from deeper parts of the Central Indian Basin (CIB). The pumice field covers an area of 600,000 km sup(2), approximately ... -
Determination of net shroe drift direction of central west coast of India using remotely sensed data
(Coastal Research Foundation, 1993) -
Foraminifera and changing pattern of monsoon rainfall
(Current Science Association, Bangalore, India, 1993)The palaeomonsoonal history can be reconstructed utilizing climatically sensitive properties of marine microorganisms; foraminifera. The results show a major boundary at 3500 years B.P. and periods of rather low precipitation ... -
Evidence for the formation of different-sized nodules by different accretionary processes
(Taylor and Francis, 1993)Studies on different-sized polymetallic nodules from the Central Indian Ocean Basin reveal that chemical composition is largely related to the nodule diameter which show systematic decrease in Mn, Cu, and Ni content with ... -
Distribution patterns of Recent planktonic foraminifera in surface sediments of the western continental margin of India
(Elsevier, 1993)Study of Recent plankton foraminifera from the surface sediment samples of western continental margin of India reveals the ecological preferences of the different planktonic foraminifera species in the area. Higher absolute ... -
Neogene oceanographic variations recorded in manganese nodules from the Somali Basin
(Elsevier, 1993)A detailed study of a nodule from the Somali Basin datEd. by sup(230)Th sub(excess) was correlated with the paleoceanographic events recorded in Site 236 (Leg 24) Deep Sea Drilling Project (DSDP) cores. Tentative indications ... -
Ferromanganese micronodules from Bengal Fan
(Museo Geologico di Bologna, 1993)The occurrence of ferromanganese micronodules, hitherto unreported from any fan-valley system of the world, has been recorded from over 0.22 million km sup(2) area located in the middle fan region of the Bay of Bengal. ... -
