Late Pleistocene sedimentation: A case study of the central Indian Ocean Basin
(Pergamon, 1993)Concentration-depth profiles of excess sup(230)Th have been measured in five sediment cores from the central Indian Ocean Basin to determine their accumulation rates and excess sup(230)Th flux to the depositional environment. ... -
Remote sensing approach to determine net shore drift direction- A case study along the central east coast of India
(Coastal Research Foundation, 1993) -
Mean proloculus size, delta super(13) C and delta super(18) O variations in recent benthic foraminifera from the west coast of India and their climatic implications
(Indian Society of Earth Sciences, Calcutta, 1993)The interrelationship between mean proloculus size (MPS), delta super(18) O and delta super(13) C vatiations in benthic foraminiferal species Rotalidium annectens and their relation with temperature (T) and salinity (S) ... -
Two computer programs for the analysis of marine magnetic data

Studies on sound signal scattering from varying seabed sediments of the western continental shelf of India: Cochin to Mangalore
(Cochin University of Science and Technology, Cochin, 1993)A study on the interaction effect of the acoustic signal with three different sediment type seabottoms off the shelf area between Cochin and Mangalore of the west coast of India is performed. Analyses by means of Probability ... -
Geochemical studies in the Godavari Estuary, India
(Elsevier, 1993)The dissolved O sub(2), Fe, dissolved organic carbon (DOC), particulate organic carbon (POC), silica and U isotope measurements in reiver-estuarine waters of the Godavari and the concentrations of 23 elements in the suspended ... -
Subsurface precambrian ridge on the continental shelf of western India between Coondapoor and Kasaragod
(Elsevier, 1993)Bathymetric and magnetic data along seven ENE-WSW and seventeen NNW-SSE and N-S profiles collected on the southwestern continental shelf of India between Coondapoor and Kasaragod within water depths of 20-2000 m are studied. ... -
Spatial and temporal variations of carbonate content in the beach and nearshore environments off Goa, west coast of India
(NISCAIR, New Delhi, 1993)Sediment samples collected from dunes, beaches (Calangute, Baina and Colva) and nearshore environments along the coast of Goa, have been analysed for their carbonate content. The results show the presence of very high ... -
Reactivation of precambrian faults on the southwestern continental margin of India: Evidence from gravity anomalies
(Elsevier, 1993)Gravimetric and bathymetric studies on the southwestern continental margin of India confirm the extension of onshore NW-SE-, NNW-SSE-, N-S-, NE-SW-, ENE-WSW- and E-W-trending lineaments of Precambrian age over a considerable ... -
Geophysical studies over a segment of the Carlsberg Ridge, Indian Ocean
(Elsevier, 1993)The study of magnetic, gravity and bathymetric data over a segment of Carlsberg Ridge between 3 degrees and 4 degrees N lat., and 63 degrees 30' and 64 degrees 30'E long. revealed the presence of a prominent 57 degrees W ... -
Geochemistry of deep-sea sediment cores from the Central Indian Ocean Basin
(NISCAIR, New Delhi, 1993)Four sediment cores from the Central Indian Ocean Basin (CIOB) were studied to characterise the coarse fraction (less than 63 mu), transition metal and major oxide contents. Transition metals (Mn, Cu, Ni, Zn) show enrichment ... -
Structural lineaments from the magnetic anomaly maps of the eastern continental margin of India (ECMI) and NW Bengal Fan
(Elsevier, 1993)Three major structural lineaments are inferred from the magnetic and bathymetry data collected over the eastern continental margin of India (ECM) and NW Bengal Fan, covering the area between 10 degrees 55'N to 20 degrees ... -
Quantification of changes in seabed topography with special reference to Hansthal Creek, Gulf of Kachchh, India
(Coastal Research Foundation, 1993)Variations in the bathymetry in macrotidal Hansthal Creek between 1984 and 1950 along 14 closely spaced lines, are used to quantify the volumetric changes in seabed topography in terms of erosion/accretion. Two surfaces ... -

Carbon dioxide and nitrous oxide in the Arabian Sea
(American Geophysical Union, 1993)This review concentrates on some aspects of biogeochemical cycling of carbon and nitrogen in the Arabian Sea with emphasis on the atmospheric fluxes of CO sub(2) and N sub(2)O. The Arabian Sea appears to serve as a net ... -
State of oil pollution in the northern Arabian Sea after the 1991 Gulf oil spill
(Pergamon, 1993)Following the enormous oil spills resulting from the 1990-91 military conflict in the Gulf, fears were expressed concerning dissipation of oil from the Gulf into the Arabian Sea and Indian Ocean. To investigate contamination ... -
Dissolved particulate and sedimentary humic acids in the mangroves and estuarine ecosystem of Goa, west coast of India
(NISCAIR, New Delhi, 1993)Highest concentration of humic acids in all the three forms (dissolved, particulate and sedimentary) was found in the monsoon (June-September) when the salinity was minimum while the lowest concentrations was observed in ... -
