Rare earth element patterns of the Central Indian Basin sediments related to their lithology
(American Geophysical Union, 1992)Rare earth element (REE) concentration have been determined in terrigenous, siliceous (nodule barren and nodule bearing), calcareous, and red clay from the Central Indian Basin. The bulk distribution of REE, and in particular ... -
A study on the evolution of Indian Ocean triple junction and the process of deformation in the Central Indian Basin
(Oxford and IBH, New Delhi, 1992)It is generally presumed that the intraplate deformation in the Central Indian Basin (CIB) is a direct consequence of spreading across the South East Indian Ridge and the resistance to shortening at the continental collision ... -
The reciprocity between coiling direction and dimorphic reproduction in benthic foraminifera
(The Geological Society Publishing House, 1992)There are various opinions as to what parameter influences the coiling directions in foraminifera. "Do microspheric and megalospheric generations have different coiling ratios?" is an unanswered question in foraminiferal ... -
Propagation of bottom-trapped waves over variable topography
(Elsevier, 1993) -
Variation of longshore current and sediment transport along the south Maharashtra coast, west coast of India
(NISCAIR, New Delhi, 1993)The longshore current velocity varied between 0.1 and 0.33 m.sec/1. The longshore current direction was predominantly southward at Ratnagiri, Ambolgarh (Maharashtra, India), whereas it was variable at Vengurla during the ... -
Hydrography and circulation of the Bay of Bengal during early winter, 1983
(Pergamon, 1993)The large-scale circulation and the distributions of temperature, salinity and density in the Bay of Bengal during early winter (October-December 1983) are presented. The surface circulation relative to 1000 db level surface ... -
A statistical method to get surface level air-temperature from satellite observations of precipitable water
(Oceanographic Society, Japan, 1993) -
Shore protection structures along Kerala coast-low cost alteratives
(Kerala Science Congress, 1993)Several studies over the last two decades on low cost shore protection measures are reviewed to have an integrated profile with a point on application to the sheltered coasts of Kerala. It is emphasised that these alternative ... -
Acoustic characteristics of the water of the Bay of Bengal
(NISCAIR, New Delhi, 1993)Acoustic eigen rays (rays connecting the source and receiver) have been indentified and their turning depth, path length, travel time etc. evaluated. Acoustic intensity loss due to mean environmental conditions, vergence ... -
Current structure and volume transport across 12 degrees N in the Bay of Bengal
(NISCAIR, New Delhi, 1993)Geostrophic currents and the associated volume transport across 12 degrees N in the Bay of Bengal during early southwest monsoon (April), southwest monsoon (September) and early northeast monsoon (November) show flow ... -
Current and temperature structure of Rihand Lake
(Indian Association for Limnology and Oceanography, India, 1993)The environmental parameters such as wind, water and air temperatures, and currents were measured in Rihand Lake, Madhya Pradesh, India during the hotest months, May-June of 1983. Rihand is an artificial lake having an ... -
The movement and implications of the Ganges-Bramhaputra runoff on entering the Bay of Bengal
(Current Science Association, Bangalore, India, 1993)The Ganges-Brahmaputra rivers discharge annually approximately 10 sup(2) m sup(3) of freshwater into the Bay of Bengal at its northern end. We propose that the spread of this water, accompaniEd. by mixing with the ambient ... -
Interpretation of nonlinearity in wind generated ocean surface waves
(NISCAIR, New Delhi, 1993)This study attempts to resolve a mix-up between a physical process and its mathematical interpretation in the context of wind waves on ocean surface. Wind generated wave systems, are conventionally interpreted as a result ... -
Shoreline dynamics of the Lakshadweep Islands
(NISCAIR, New Delhi, 1993)Lakshadweep group of islands are mainly coral atolls. Fringing reefs protect these small islands from the attack of waves. This paper describes the waves and currents acting on Kalpeni, Kavaratti, Minicoy, Agatti, Kadamat ... -
Deep water wave characteristics off Karwar, west coast of India
(NIO, Goa, 1993) -
A comparison of synthetic aperture radars applied for satellite remote sensing of the ocean surface
(1993)Doppler imaging radars have orbited the earth aboard several spacecraft for the purpose of monitoring the ocean. Oceanographic applications of synthetic aperture radar (SAR) include measuring ocean wave fields, monitoring ... -
The western boundary current of the seasonal subtropical gyre in the Bay of Bengal
(American Geophysical Union, 1993)Hydrographic data collected during March-April 1991 show the presence of a poleward current along the western boundary of the Bay of Bengal of about 10 degrees N carrying warmer waters of southern origin. The inshore side ...
