Establishment of gravity stations and inference of crustal thickness around Mormugao Harbour and NIO
(Geological Society of India, 1995)Complete descriptions and basic facts of nine gravity stations of Marmugao Harbour, Goa, India are presented. They exhibit a maximum Bouguer difference of 2.12 mGal in an overall distance of about 2 km. Keeping in view the ... -
Supra-generic radiolarian transfer function based late Miocene palaeomonsoonal changes in the northeastern tropical Indian Ocean
(Indian Geological Association, 1995)A Q-mode factor analysis of the % data of 25 broadly defined supra-generic radiolarian groups in 42 deep-sea surface sediments produced four statistically significant and geographically distinct faunal assemblages related ... -
Geochemistry of calcareous sediments from the SW Carlsberg Ridge: Evidence for deeper carbonate compensation depth
(NISCAIR, CSIR, 1995)Concentration of Mn, Fe, Ni, Co, Zn, Ca, Mg, K, Al, Si, Ti, P and CaCO sub(3) show wide range for the calcareous sediments from SW Carlsberg Ridge (CR). Compared with the average pelagic clays, the CR sediments are enriched ... -
Marine sediments and palaeoclimatic variations since the Late Pleistocene: An overview for the Arabian Sea
(Geol. Soc. India, Bangalore, 1995)A large number of surfacial and sub-surface sediments from the Arabian Sea have been studied to enhance our understanding of palaeoclimatic variations over the Indian region. Bsically the surficial sediments have been ... -
Fresh pumice from the Central Indian Basin: A Krakatau 1883 signature
(Elsevier, 1995)The occurrence of pumice in the Central Indian Basin (CIB) has been a controversy. Some are of the opinion that these pumices are erupted from a volcano along the Ninetyeast ridge while others suggest the Indonesian are ... -
Evidences for a volcanic province in the Central Indian Basin
(Geological Society of India, 1995)Based on various lines of evidence such as the widespread occurrence of basalts, pumice, volcanic glass shards and their transformational products (zeolites, palagonites, and smectite-rich sediments), we suggest the presence ... -
Palaeogene hardgrounds and associated intraclast lag deposits as the substrates of ferromanganese crusts and nuclei of nodules: Inferences of abyssal current in the Central Indian Ocean Basin
(Palaeontological Society of India, 1995)The Palaeogene substrates of ferromanganese crusts and nuclei of nodules collected from the Central Indian Basin chiefly consist of incipient to younger pelagic hard grounds and associated intraclast lag deposits. The ... -
Integration of deeptow data for mapping of deepsea resources
(Int. Soc. Offshore and Polar Eng., Japan, 1995)Deeptowed photographic and acoustic surveys in the Pioneer Area in Central Indian Basin, resulted in collection of 52,295 photographs, 450 hours of video record and 1129 km of sub-bottom and side scan data. Data-processing ... -
Flow effects on a pressure sensor

Wave transmission by suspended pipe breakwater
(American Society of Civil Engineers, 1995)A suspended pipe Breakwater was designed specifically for fishery/pleasure-craft harbors where moderate wave agitations in the harbor basin are admissible. The present breakwater consists of a row of closely spaced pipes ... -

Studies on a 120 degrees segmented circular array for multi-beam multi-frequency bathymetric application
(Academic Press, 1995)A theoretical analysis of the vertical for field patterns and input impedances, as well as excitation velocities of a 120 degrees segmented circular array of 40 groups of four elements each is performed. The narrowest beam ... -
Estuarine response of fluoride - Investigations in Azhikode Estuary
(Kalpana Corporation, 1995)Concentrations of fluoride in Azhikode estuarine region (Kerala, India) were measured as a function of chlorinity during the different seasons. The type of behaviour indicated that fluoride was regulated by sea water ... -
Seawater intrusion and behaviour of dissolved boron, fluoride, calcium, magnesium and nutrients in Vashisti Estuary
(Society of Biosciences, Muzaffarnagar, India, 1995)Behaviour of dissolved B, F, Ca, Mg and nutrients in partially stratified estuary of Vashiti River, Karnataka, India has been studied under stable conditions of riverine flow. The dominance of Mg over Ca concentration in ... -

Computation of dilution discharge and mean concentration of effluents in Beypore Estuary, west coast of India
(Palani Paramount Publications, 1995)Tide dominated Beypore estuary along the west coast of India was studied to estimate the mean flow available for diluting the conservative effluents based on the distribution of ambient salinity as a guide through one ... -
Seasonal variations in halides in marine brown algae from Porbandar and Okha coasts (NW coast of India)
(NISCAIR, CSIR, 1995)Seasonal variation of halides and their ratios were estimated in three brown algae, namely Cystoseira indica, Sargassum tenerrimum) and S. johnstonii from Porbandar and Okha Coasts. Halides were found to be higher in early ... -
Autotrophic and heterotrophic characteristics in a polluted tropical estuarine complex
(Academic Press, 1995)Some species of microbial heterotrophic communities (14C glucose uptake and respiration; viable nad total bacterial numbers) and autotrophic communities (primary production rate, chlorophyll a, phytoplankton cell counts ... -
