River inputs and organic matter fluxes in the northern Bay of Bengal: Fatty acids
(Elsevier, 1993)Total particulate matter flux and organic carbon and fatty acid fluxes associated with settling particles collected during the summer-monsoon period of 1988 using time-series sediment traps deployed at two depths (809 and ... -
An intermediate nepheloid layer associated with high microbial metabolic rates and denitrification in the northwest Indian Ocean
(American Geophysical Union, 1993)Extensive optical, physical chemical, and biochemical measurements made simultaneously in the northwest Indian Ocean reveal the occurrence of an intermediate nepheloid layer (INL) invariably associated with the secondary ... -
Influence of seabed topography on the distribution of manganese nodules and associated features in the Central Indian Basin: A study based on photographic observations
(Elsevier, 1993)The distribution of manganese nodules and associated rock outcrops and sediment cover in the Central Indian Basin (10 degrees-16 degrees S, 73 degrees-82 degrees E), were studied from seabed photographs in relation to ... -
Deposition of Mn-Cu-Ni-enriched sediments during glacial period in the Central Indian Basin
(Current Science Association, Bangalore, India, 1993)Two siliceous sediment cores collected from the Central Indian Basin have been analysed for organic carbon, biogenic silica, Al, Mn, Ni and Cu content. The concentrations of Mn, Cu and Ni showed one order of magnitude ... -
Manganese micronodules: A possible indicator of sedimentary environments
(Elsevier, 1993)Manganese micronodule distribution, size, internal features and chemical composition as well as the composition of associated sediments have been determined in eight sediment cores taken from the siliceous ooze area of the ... -
Magnetic lineations, fracture zones and seamounts in the Central Indian Basin
(Elsevier, 1993)Magnetic and bathymetric data collected in the Central Indian Basin, between 8 degrees S and 16 degrees S lat., and 71 degrees E and 82 degrees E long. have been studied. The inferred fracture zones at 73 degrees E, 76 ... -
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 ...
