A new report on the occurrence of zeolitites in the abyssal depths of the Central Indian Basin
(Society for Sedimentary Geology, 1993)Forty-two indurated slabs of zeolites collected from the abyssal depths of the Central Indian Basin have been studied. The slabs show characters similar to harmotome-rich scorias of the Society Ridge and phillipsite slabs ... -
Chemical oceanography of the Arabian Sea Part iv Laccadive sea
(CSIR-NISCAIR, 1979)Data collected during the 10th (October 1976) and 31st (March-April 1978) cruises of R V Gaveshani suggest that water movements, considered typical of island-arc regions, are responsible for high levels of productivity ... -
Chemical oceanography of the Arabian Sea: Part 1 - Hydrochemical and hydrographical features of the Northern basin
(CSIR-NISCAIR, 1975)Three water masses in the Arabian Sea have been identified from their physical and chemical characteristics: (i) water mass which originates in the surface layer and has high salinity,low oxygen and high pH ; (ii) water ... -
Chemical oceanography of the Arabian Sea: Part II - Equilibrium of inorganic nitrogen system
(CSIR-NISCAIR, 1975)The concept pE, expressed as a dimensionless quantity to study the redox potential of a system at equilibrium, is applied to study the chemistry of the system NO-<sub>3</sub>-NO-<sub>2</sub>NH+<sub>4</sub> in the northern ... -
Chemical oceanography of the Arabian Sea: Part III - Studies on nutrient fraction and stoichiometric relationship in the Northern and the Eastern Basins
(CSIR-NISCAIR, 1976)Phosphorus and inorganic nitrogen compounds have been divided into 'reserved' andoxidative fractions based on their relationships with apparent oxygen utilization in the northern and the north-eastern basins of the Arabian ... -
Chemical oceanography of the Arabian Sea: Part vi - Relationship between nutrients and dissolved oxygen in the central basin
(CSIR-NISCAIR, 1986)Inorganic nitrate and phosphate relationships with apparent oxygen utilization (AOU) in the Central Arabian Sea were studied using data collected during 103 cruise of R V Gaveshani (Feb. 1982). The consolidated ratio of ... -
Coexistence of pumice and manganese nodule fields-evidence for submarine silicic volcanism in the Central Indian Basin
(Pergamon, 1993)Pumice, of various shapes and sizes, uncoated or coatEd. by ferromanganese oxides, have been recovered from deeper parts of the Central Indian Basin (CIB). The pumice field covers an area of 600,000 km sup(2), approximately ... -
Deciphering detailed plate kinematics of the Indian Ocean and developing a unified model for East Gondwanaland reconstruction: An Indian-Australian-French initiative
(Department of Science and Technology , India, 2013)The Indian Ocean formed as a result of the fragmentation and dispersal of Gondwanaland since the Jurassic. The deep ocean basins in the Indian Ocean contain the imprints of this plate tectonic history, which is related ... -
Global patterns and predictions of seafloor biomass using random forests
(Public Library of Science, 2010)A comprehensive seafloor biomass and abundance database has been constructed from 24 oceanographic institutions worldwide within the Census of Marine Life (CoML) field projects. The machine-learning algorithm, Random ... -
Synthesis of morphotectonics and volcanics of the Central Indian Ocean Basin
(Current Science Association, Bangalore, India, 1999)The Central Indian Ocean Basin (CIOB) is an enigmatic ocean basin in the young and tectonically complex Indian Ocean. Major tectonic and volcanic forms identified are fracture zones, abyssal hills, seamounts and ridges and ... -
Tectonics of the Ninetyeast Ridge derived from spreading records in adjacent oceanic basins and age constraints of the ridge
(American Geophysical Union, 2012)Analysis of new and existing geophysical data for the Central Indian and Wharton Basins of the Indian Ocean were used to understand the formation and evolution of the Ninetyeast Ridge (NER), especially its relationship to ... -
The distribution of the chaetognath population and its interaction with environmental characteristics in the Bay of Bengal and the Arabian Sea.
(Taylor and Francis, 2015)The Bay of Bengal (BoB) and the Arabian Sea (AS), the two major ocean basins in the north Indian Ocean, share similarities in geographical and meteorological characteristics but differ in hydrographic characteristics and ... -
Western Indian Ocean - A glimpse of the tectonic scenario
(Oxford and IBH, New Delhi, 2001)The Western Indian Ocean is a veritable storehouse of diverse and complex tectonic features. Most of the knowledge about the major tectonic features of this area has emanated from the studies carried out with the geophysical ...
