Australasian microtektites in a substrate: A new constraint on ferromanganese crust accumulation rates
(Elsevier, 1994)Microtektites belonging to the Australasian tektite strewn field are found in the substrate of a ferromanganese crust dredged from the Central Indian Basin. They are identified on their physical appearance, geographic ... -
234Th scavenging and particle export fluxes from the upper 100 m of the Arabian Sea
(Current Science Association, 1996)We have determined the particle scavenging rates, export fluxes of @u234@@Th and settling particles from the upper 100 m of the Arabian Sea as a part of the JGOFS (India) Programme. The spatial and temporal measurements ... -
Benthic foraminifera as pollution indices in the marine environment of west coast of India
(Universita' degli Studi di Milano, 1984)Two ecosystems affected by acidic pollutants (Thana Creek, Bombay and inshore area of Trivandrum, Kerala) and two other ecosystems affected by alkaline pollutants (Cola Bay, Goa and inshore area of Karwar, Karnataka) were ... -
Microenvironments and anomalous benthic foraminiferal distribution within the neritic regime of the Dabhol-Vengurla sector (Arabian Sea)
(Universita' degli Studi di Milano, 1980)An anomalous distribution of benthic Foraminifera within the neritic regime at a few stations indicates the existence of microenvironments. The vertical distribution is marked by the restricted occurrence of @iCibicides@@ ... -
Foraminiferal Constituent in Marine Sediments - A Parameter in some Coastal Engineering Problems
(Indian Association for Limnology and Oceanography, 1980)Foraminifera, among other microorganisms, form a major constituent of marine sediments and their composition is directly related to the nature of the substrate in which they are entombed. Past and the present data indicate ... -
Graphic pattern of foraminiferal dominance in nearshore region of central west coast of India
(Indian Association for Limnology and Oceanography, 1979)Within the inner neritic zone (0-55 m depth) along the central west coast of India, some foraminiferal groups such as @iAmmonia, Elphidium, Trochammina, Bulimina, Bolivina, Nonion, Nonionella@@ and Florilus@@ individually ... -
Seasonal wave characteristics of the Arabian Sea and the Bay of Bengal
(Marine Biological Association of India, 1976)Wave data reported in the Indian Daily Weather Reports for the period 1960-64 have been used to evaluate seasonal wave characteristics for each 2-degree square areas of the Arabian Sea and the Bay of Bengal. These results ... -
Shelf edge regime and foraminifera off Pondicherry, Bay of Bengal
(CSIR-NISCAIR, 1978)Occurrence of @iGloborotalia menardii neoflexuosa, Globoquadrina conglomerata@@ and @iNeogloboquadrina pachyderma dextralis typica@@ in the sediments is significant, as these are also reported from the Arabian Sea earlier, ... -
Distribution of phosphorus and organic carbon in the nearshore sediments of Goa
(CSIR-NISCAIR, 1973)Samples collected from sediment water interface from the inner shelf region of Goa coast are examined for their phosphorus and organic carbon, which indicate the geochemical environment under which the present day deposits ... -
Occurrence of Neogloboquadrina pachyderma new subspecies in the shelf-slope sediments of northern Indian Ocean
(CSIR-NISCAIR, 1977)Specimens of @iNeogloboquadrina pachyderma@@ (Ehrenberg) which are considered to be typical bipolar, coolerwater species, are described in the recent shelf-slope sediments of the northern Indian Ocean as far north as 23~'N ... -
Growth inhibition of fouling bacteria and diatoms by extract of terrestrial plant, Derris scandens (Dicotyledonae:Leguminocae)
(CSIR-NISCAIR, 1995)Methanol extract of terrestrial plant, @iDerris scandens@@ Benth, was found to inhibit growth of four diatoms and 7 bacterial species of fouling community. The concentrations required to bring about 100% inhibition of ... -
Sustainable brackishwater industrial aquaculture and management of environment- use of ozone
(Fishing Chimes�group of publications, 1995)Surveys conducted in aquaculture farm showed that oxygen level varies between 3 to 5 ml. oxygen per litre. This is not adequate for high production and also cause pollution. However if aeration is replaced with positively ... -

Evaluation of Co-rich manganese deposits by image analysis and photogrammetric techniques
(Osaka: International Society of Offshore and Polar Engineers, 1994)Stereo-seabed photographs of Co-rich manganese deposits on a mid-Pacific seamount, were analysed using an image analysis software for coverage estimation and size classification of nodules, and a photogrammetric software ... -
Uranium series disequilibrium in the coastal surface sediments and sea water of the Arabian sea
(Elsevier, 1988)Nearshore surface sediments from various locations of the West Coast of India were leached by saturated ammonium carbonate solution for the extraction of uranium isotopes. The reagent chosen was found to have high efficiency ...
