Major elements, nutrients, and plankton biomass in the ice edge and an offshore region of the Indian Ocean sector of the Southern Ocean
(Cambridge University Press, 1992) -
Fluxes of amino acids and hexosamines to the deep Arabian sea
(Elsevier, 1992)Results of organic carbon, total nitrogen, amino acid and hexosamine of samples collected during time-series sediment trap in investigations in the Arabian Sea are presented. Samples were taken over a period of 1 1/2 years ... -
Production of organic matter in Antarctic ice shelf
(NISCAIR, New Delhi, 1992) -
The importance and measurement of new production
(Plenum, 1992) -
Planning and management of the coastal zone in India - A perspective
(Taylor and Francis, 1992)India's coastal zone has, since ancient times, played a very significant role in socioeconomic, political, and defense developments. For a developing country like India with a vast coastal zone, there is a need for ... -
Some aspects of the nitrogen cycling in the Arabian Sea
(Oxford and IBH, New Delhi, 1992)Extensive observations made in the Arabian Sea establish it as one of the largest oceanic reducing sites accounting for approximately 1/3 of the global water column denitrification. Evidence for large short-term (seasonal) ... -
Coastal zone: Shelf-EEZ and land sea interface
(T.N.Malhotra Pub. House, 1992)Among the few vibrant ecotopes is the coastal zone, where multifaceted interactions among air, sea and land are dynamically balanced. An area of intense clash of interest of user community, the coastal zone harbouring vast ... -
Monosaccharide composition of suspended particles from the Bay of Bengal
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 1992)Neutral carbohydrates were determined as alditol acetates by capillary gas chromatography in the hydrolysates of suspended particulate samples (40) collected from 8 depths (approx 1 to 1,000 m) at 5 stations of the Bay of ... -
The effect of organic matter associated with the corrosion products on the corrosion of mild steel in the Arabian Sea
(Pergamon, 1992)The corrosion of mild steel immersed at various depths (0-100 m) from three stations of the Arabian Sea was investigated. The corrosion of mild steel decreased with increasing immersion depth. Significant positive relationships ... -
Size-fractionated biomass, photosynthesis and dark CO2 fixation in a tropical oceanic environment
(Cambridge University Press, 1992)This study examines the spatial distribution and size structure of phytoplankton biomass and productivity in relation to the vertical structure of the Andaman Sea (northern Indian Ocean). This region was characterizEd. by ... -
Tectonic reactivation in the Indian Ocean: Evidences from seamount morphology and manganese nodule characteristics
(Geological Society of India, 1992)The Central Indian Ocean Basin (CIOB) was subjected to tectonic reactivation in geological past which is unusual for a basin occurring on an apparently single tectonic plate. ENE-WSW trending latitude parallel zone of ... -
Foraminiferal production and monsoonal upwelling in the Arabian sea: evidence from sediment traps
(Geological Society of London, 1992)Planktonic foraminifera collected in sediment traps in the Arabian Sea during 1986 and 1987 responded to the southern Asian monsoon with changes in productivity, relative abundance of species and isotopic shell chemistry. ... -
Can benthic foraminiferal morpho-groups be used as indicators of paleomonsoonal precipitation?
(Academic Press, 1992)A technique is proposed for the quick and easy assessment of paleomonsoonal precipitation through the study of morphological groups of foraminifera in a shallow water (20 m water depth) sediment core collected off Karwar, ... -
Changing sedimentary environments during Pleistocene-Holocene in a core from the eastern continental margin of India
(Geological Society of India, 1992)Sedimentological and geochemical investigations of the sediments in a core from the eastern continental margin of India, at a water depth of 1200 m, revealed two distinct types. The Late Pleistocene sediments are greyish-black ... -
Slope angle studies from multibeam sonar data on three seamounts in Central Indian Basin
(Offshore Technology Conference, 1992)Slope angles are powerful morphometric tools. Slope angle studies in manganese nodule areas using the Multi Beam Sonar (MBS) data is useful to the mining geologist. A technique to convert depth grid generated from MBS data ... -
Particle fluxes in the Bay of Bengal measurEd. by sediment traps
(Geological Survey of India, 1992)Particle fluxes were measured between October, 1987 and March, 1988 using six automated time series sediment traps at three locations in the northern, central and southern Bay of Bengal. Particle fluxes varied between 16.8 ... -
Distribution of nodules and associated features in the Central Indian Basin: observations from seabed photogarphs
(Oxford and IBH, New Delhi, 1992)Observations from more than one thousand seabed photographs, have brought out various factors which influence the distribution of nodules, sediments and rocks and as a result six different phases have been identified for ... -
A re-evaluation of palaeoclimatic conditions during the Pleistocene and Holocene from the western continental shelf of India - Evidences from the petrology of the limestones
(Oxford and IBH, New Delhi, 1992)The western shelf of India is characterisEd. by the presence of Recent clayey sediments on the inner shelf and relict carbonate sediments and a variety of limestones on the outer shelf. The limestones of the outer continental ... -
Geotechnical properties of deep-sea sediments from central Indian Ocean Basin
(NISCAIR, New Delhi, 1992)Physical and geotechnical properties of 2 sediment cores from the nodule rich area of the Central Indian Ocean Basin are studied to know the sediment characteristics. Average water content of sediment from 2 deep-sea cores ...
