Characterization of chlorophyll-a over CAL-VAL site at Kavaratti in the Lakshadweep Sea
(Taylor & Francis, 2009)Under the Meteorology and Oceanography Programme (MOP) of the Indian Space Research Organization (ISRO), a Calibration-Validation site is planned at Kavaratti in the Lakshadweep Sea with a pair of moored data buoys consisting ... -
An expeditious I sub(2)-catalyzed entry into 6H-indolo[2,3-b]quinoline system of cryptotackieine
(American Chemical Society, 2009)A synthesis of a series of novel 6H-indolo[2,3-b]- quinolines with different substituents on the quinoline ring is described. The method involves reaction of indole-3-carboxyaldehyde with aryl amines in the presence of a ... -
A new xenicane norditerpene from the Indian marine gorgonian Acanthogorgia turgida
(Taylor & Francis, 2009)Chemical investigation of the liposoluble extract of the gorgonian Acanthogorgia turgida, from Indian coasts, led us to isolate a new xenicane-based norditerpene, isoacalycixeniolide-A (1), along with the known structurally ... -
Glass and mineral chemistry of northern central Indian ridge basalts: Compositional diversity and petrogenetic significance
(The Geological Society of China, 2009)The glass and mineral chemistry of basalts examined from the northern central Indian ridge (NCIR) provides an insight into magma genesis around the vicinity of two transform faults: Vityaz (VT) and Vema (VM). The studied ... -
Mesozooplankton community in the Bay of Bengal (India): Spatial variability during the summer monsoon
(Springer, 2009)This study addresses the spatial variability in mesozooplankton biomass and composition in the Central and Western Bay of Bengal (India) during the summer monsoon season of 2001. Perennially warmer sea surface temperatures ... -
Bacterioplankton abundance and production in Indian Ocean Regions
(American Geophysical Union, 2009)Microbes mediating biological and many geochemical processes are the key components in marine ecosystems. Information on spatiotemporal variations in heterotrophic bacterial (Hbac) abundance and production in three ... -
Reply to the comment on 'Petrography and chemistry of basalts from the Carlsberg Ridge` by R Banerjee and S.D Iyer

Distribution of Bowen ratio over the north Indian Ocean
(India Meteorological Department, 1986)The monthly averages of Bowen ratio over the north Indian Ocean have been computed Three typical situations in the months of January May and September are taken for the present study Month to month differences in the Bowen ... -
The Lignin-Degrading Enzyme, Laccase from Marine Fungi : Biochemical and Molecular Approaches
(2008)The object of the present study was to isolate and identify obligate marine or marine-derived fungi that were hyper-laccase producers. The laccase from the selected marine-derived fungus was to be characterized and its ... -
Pigment and amylase production in Penicillium sp NIOM-02 and its radical scavenging activity
(Institute of Food Science and Technology, 2009)Penicillium sp NIOM-02 was isolated from the marine sediment, produced red pigment. The pigment extracted from this fungus scavenged 2, 2-diphenyl-1-pycrylhydrazyl (DPPH) radical. Penicillium sp NIOM-02 grown in media ... -
Microbially mediated redox transformations of manganese (II) along with some other trace elements: a study from Antarctic lakes
(Springer, 2009)The significance of freshwater systems in global manganese cycles is well appreciated. Yet, the polar systems, which encompass the largest freshwater repository in the world, have been least studied for their role in ... -
Effects and interactions of medium components on laccase from a marine-derived fungus using response surface methodology
(Molecular Diversity Preservation International, 2009)The effects of various synthetic medium components and their interactions with each other ultimately impact laccase production in fungi. This was studied using a laccase-hyper-producing marine-derived basidiomycete, Cerrena ... -
Composition of macrobenthos from the central Indian Ocean Basin
(Indian Academy of Sciences, 2009)The deep sea is well known for its high faunal diversity. But the current interest in its abundant polymetallic nodules, poses a threat to the little known benthic organisms surviving in this unique environment. The present ... -
Hydrothermal alteration studies of gabbros from northern central Indian ridge and their geodynamic implications
(Indian Academy of Sciences, 2009)Mylonitic gabbro and altered gabbro were recovered from off-axis high and corner high locations at ridge-transform intersection, adjacent to Vityaz transform fault of the slow spreading (32-35 mm/yr, full spreading) Northern ... -
Structural studies and antimicrobial properties of norcembrane diterpenoid from an Indian soft coral Sinularia inelegans Tixier-Durivault
(Indian Academy of Sciences, 2009)Two metabolites featuring norcembranoid diterpene skeleton have been isolated from chloroform extract of soft coral of the genus sinularia, which was collected from the southern coast of India. The structures of the ... -
Multi-beam backscatter image data processing techniques employed to EM 1002 system
(CUSAT, 2009)Application of multi-beam bathymetric data provides interesting seafloor features. Besides obtaining bathymetric data for seabed characterization backscatter data is also important. However, use of raw multi-beam backscatter ... -
CO2 supersaturation and net heterotrophy in a tropical estuary (Cochin, India): Influence of anthropogenic effect - Carbon dynamics in tropical estuary
(Springer, 2009)Carbon biogeochemistry of a tropical ecosystem (The Cochin Estuary, India) undergoing increased human intervention was studied during February (premonsoon), April (early monsoon) and September (monsoon) 2005. The Cochin ... -
A one year comparison of radar and pressure tide gauge at Goa, west coast of India
(CUSAT, 2009)At many locations absolute pressure gauges are used to obtain sea level data. Therefore, knowledge of the other physical processes which effect the sea level measurements at the coast is very important to insert the required ... -
