Seasonal variation in an annually-banded coral Porites: A scanning electron microscopy investigation
(Elsevier, 1994)Seasonal bands of the hard coral @iPorites@@ sp. collected from three different islands of Lakshadweep (Northwest Indian Ocean) are examined under a scanning electron microscope (SEM). SEM photographs reveal the presence ... -
Identification and origin of a subsurface ridge on the continental margin of western India
(Elsevier, 1994)Gravity and magnetic studies in the eastern Arabian Sea reveal the presence of subsurface and exposed ridges on and beyond the continental shelf of western India. Distinct patterns of geophysical anomalies are associated ... -
Sediment transport along the Goa-north Karnataka Coast, western India
(Elsevier, 1994)Landsat images, aerial photographs, and topographic maps of the coast of Goa and of north Karnataka were interpreted to delineate sediment-transpoet sectors. Thirty six sediment-transpoet sectors were identified from ... -
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 ... -
