Late Quaternary record of pteropod preservation from the Andaman Sea
(Elsevier, 2010)In order to understand the glacial to interglacial fluctuations in pteropod preservation and productivity during the late Quaternary (approx. 54 ka BP to present), we investigated pteropod, organic carbon (C sub(org)) and ... -
Late Quaternary sea level and environmental changes from relic carbonate deposits of the western margin of India
(Indian Academy of Sciences, 2003)Relic carbonate deposits along the western margin of India occur as dolomite crusts, aragonite sands (pelletal / oolitic) and aragonite-cemented limestones, oyster shells, corals, encrusted coralline algal and foraminife ... -
Late Quaternary Sedimentation and Slope Failure Events on the Costa Rican Margin
(Springer, Cham, 2020)The Costa Rican margin is an erosional convergent margin formed by subduction of the Cocos Plate under the Caribbean Plate along the Middle America Trench. The Integrated Ocean Drilling Program (IODP) Expedition 334 was ... -
Late Quaternary sedimentation in eastern Bay of Bengal
(Oxford and IBH, New Delhi, 1992)This study presents variations in various size measures, calcium carbonate, organic carbon, clay mineralogy and major and trace elements in a core (5.40 m long, 2713 m depth) from the eastern Bay of Bengal. On a CM diagram, ... -
Late Quaternary seismic sequence stratigraphy of the Gulf of Kachchh, northwest of India
(Coastal Education and Reserch Foundation, 2009)High-resolution seismic reflection and bathymetric data in 10 to 50 m water depth in the Gulf of Kachchh, northwest of India, have been analysed together with earlier results from the area. They have revealed geomorphic ... -
Late-Quaternary variations in clay minerals along the SW continental margin of India: Evidence of climatic variations
(Springer, 2000)Down-core variations in illite, chlorite, smectite and kaolinite (the major clays) in two sup(14)C-dated cores collected along the SW continental margin of India show that illite and chlorite have enhanced abundance during ... -
Latent and sensible heat fluexes under active and weak phases of the summer monsoon of 1986
(Indian Academy of Sciences, Bangalore, 1989) -
Latent heat flux variability over the tropical Indian Ocean
(John Wiley & Sons, Ltd, 2023)The seasonal evolution and interannual variability of latent heat flux (LHF) over the tropical Indian Ocean (TIO) region is examined for the period 1980–2019. The seasonal distribution of LHF is dominated by the winter ... -
Latitudinal environmental gradients and diel variability influence abundance and community structure of Chaetognatha in Red Sea coral reefs
(Taylor & Francis, 2017)The Red Sea has been recognized as a unique region to study the effects of ecohydrographic gradients at a basin-wide scale. Its gradient of temperature and salinity relates to the Indian Ocean monsoon and associated ... -
Latitudinal range of epiplanktonic Cahetognatha and Ostracoda in the western tropical Indian Ocean
(Springer, 1984)An account of the chaetognath and ostracod species obtained from zooplankton samples collected along a transect in the Western Indian Ocean between 9 degrees N-20 degrees S and 57 degrees 18'-68 degrees 43'E in January-February ... -
Latitudinal variation of air sea fluxes in the western Indian Ocean during austral summer and fall
(Kluwer, 1989)Daily and zonal (latitudinal belt) averages of heat and momentum fluxes were computed using bulk aerodynamic formulae, from the meteorological parameters measured onboard 'M.S. Thuleland' during the sixth Indian scientific ... -
Lead distribution in coastal and estuarine sediments around India
(Elsevier, 2015)This study describes the geochemical distribution of lead (Pb) and identifies the critical factors that significantly control Pb distribution and speciation in coastal and estuarine sediments around India by using published ... -
Lead ingots from a shipwreck off Poompuhar, Tamil Nadu, east coast of India: Evidence for overseas trade and their significance
(Blackwell Publishing, 2003)Various types of lead ingots have been reported from a number of shipwrecks from different parts of the world. In 1991 exploration of a wreck off Poompuhar, Tamil Nadu, east coast of India, at a depth of 19 m yielded a ... -
Leg 179 summary
(ODP, Texas A and M Univ., USA, 1999)Ocean Drilling Program (ODP) Leg 179 set out with two primary objectives. These objectives were (1) testing the recently developed hammer drill-in casing system on the Atlantis Bank, Southwest Indian Ridge (SWIR), and (2) ... -
Leishmanicidal activity of 2-benzoxazolinone from Acanthus illicifolius in vitro

Length and weight relationship of laboratory reared penaeid prawn Penaeus monodon (Fabricius) (Crustacea: Penaeidae)
(NISCAIR, CSIR, 1997)A parabolic relationship was obtained while studying the length-weight relationship of the postlarvae of Penaeus monodon. The b value (multiplying constant) showed that in the laboratory reared penaeid prawns, length-weight ... -
Length weight relationship of Sufflamen fraenatus (Latreille, 1804) and Zenodon niger (Ruppell, 1835)
(Central Marine Fisheries Research Institute, India, 2005)The relationship between total length and total weight in balistids is not significantly different in males and females. The common equation for both the sexes in Sufflamen fraenatus is Log W= -9.0429+2.7296 log L or ... -
Length-weight relation and condition factor of Penaeus indicus and Metapenaeus dobsoni in the Cochin Backwater
(Indian Association for Limnology and Oceanography, 1983)Length-weight relation and condition factor of Penaeus indicus and Metapenaeus dobsoni were estimated using samples from Cochin backwater. Statistical tests support the view that the length-weight exponent of these species ... -
