The effect of semi-permanent eddies on the distribution of mesozooplankton in the central Bay of Bengal
(Yale University, 2008)Five locations in the central Bay of Bengal (BoB) along a longitudinal transect at 88E were sampled during the Fall Intermonsoon, 2002 for mesozooplankton biomass, abundance, groups and copepod species composition. Stations ... -
A concise synthesis of (R)-Bgugaine, a pyrrolidine alkaloid from Arisarum vulgare
(Science Reviews 2000 Ltd, 2008)A new short method for the preparation of (R)-Bgugaine (1) has been described using Wittig condensation of a nonstabilised ylide with N-carboethoxy prolinal followed by reduction of double bond and conversion of N-carboethoxy ... -
Characteristics of macrobenthic assemblage from sub-littoral sediment off the Lazarev Sea, East Antarctica
(NISCAIR, India, 2008)Comparative account of the occurrence and abundance of benthic macro-organisms collected from the Lazarev Sea in Queen Maud Land, (east Antarctica), during austral summer of 1984-85 and 1992-93 (fourth and twelfth Indian ... -
Benthic environmental baseline investigations in the manganese nodule area of the central Indian Basin
(Honolulu: International Society of Offshore and Polar Engineering, 1997)In order to exploit the manganese nodule deposits in future, an assessment of the environmental impact due to potential mining activity, has been undertaken in the Central Indian Basin Under this programme, seabed surveys ... -
