Cellular fatty acid composition of marine-derived fungi
(NISCAIR, CSIR, 2006)The present study quantifies cellular fatty acid composition of four filamentous, marine fungi viz. Trichoderma pseudokoningii, Curvularia lunata, Penicillium chrysogenum and Aspergillus niveus. These fungi were isolated ... -
Morphology and physiology of the marine straminipilan fungi, the aplanochytrids isolated from the equatorial Indian Ocean
(NISCAIR, CSIR, 2006)While thraustochytrids, a group of unicellular marine straminipilan protists, have been found to be abundant in the water column, little is known of aplanochytrids. These constitute one of the 3 groups belonging to the ... -

Response of macrobenthic communties to oil spills along Goa coast
(2007)Oil pollution is a major environmental problem and is important, in particular to the Indian coastline as two main oil tanker routes pass through the Arabian Sea. In contrary to the decrease in oil spill globally, the ... -
Evidence of shoreline shift on the northern Saurashtra coast: Study based on the submerged temple complex at Pindara
(Indian Academy of Sciences, 2007)Shoreline changes have played a vital role in emergence and devolution of any civilization along the coast. An onshore exploration on the northwestern coast of the Saurashtra, Gujarat, India brought to light the remains ... -
Platinum group elements and gold in ferromanganese crusts from Afanasiy-Nikitin seamount, equatorial Indian Ocean: Sources and fractionation
(Indian Academy of Sciences, 2007)The major element relationships in ferromanganese (Fe–Mn) crusts from Afanasiy–Nikitin seamount (ANS), eastern equatorial Indian Ocean, appear to be atypical. High positive correlations (r = 0.99) between Mn/Co and Fe/Co ... -
Influence of basin-scale and mesoscale physical processes on biological productivity in the Bay of Bengal during the summer monsoon
(Elsevier, 2007)Physical forcing plays a major role in determining biological processes in the ocean across the full spectrum of spatial and temporal scales. Variability of biological production in the Bay of Bengal (BoB) based on basin-scale ... -

Tandem mass spectrometry of kahalalides: Identification of two new cyclic depsipeptides, kahalalide R and S from Elysia grandifolia
(John Wiley, 2007)Spectra obtained using electrospray ionization mass spectrometry (ESI-MS) of mollusk Elysia grandifolia showed a cluster of molecular ion peaks centered at a molecular mass of 1478 Da (kahalalide F, an anticancer agent). ... -
A device for finer-scale sub-sectioning of aqueous sediments
(Indian Academy of Sciences, 2007)A modified hand-operated mechanical device has been developed to facilitate precise sectioning of the aqueous sediment in a core liner. The device allows the core liner to remain vertical on the disk protecting physical, ... -
Observed seasonal variability of barrier layer in the Bay of Bengal
(American Geophysical Union, 2007)The observed formation of Barrier Layer (BL) and the seasonal variability of BL thickness (BLT) in the Bay of Bengal are examined utilizing the most comprehensive data set. Thick BL (~50m) first appears in the coastal ... -
Influence of environmental properties on macrobenthos in the northwest Indian shelf
(Springer, 2007)The paper deals with the standing stock of macrobenthic infauna and associated environmental factors influencing the benthic community in the shelf region of the northwest Indian coast. The data were collected onboard FORV ... -
Shoreline changes during the last 2000 years on the Saurashtra coast of India: Study based on archaeological evidences
(Indian Academy of Sciences, 2007)Shoreline shift coupled with sea-level change have always remained intriguing aspects due to wider ramifications for the populations living on the coast. Different methods are employed to understand and explain their causes ... -
Sediment - size distribution of innershelf off Gopalpur, Orissa coast using EOF analysis
(Geological Society of India, 2007)Earlier studies on grain-size analysis of sediment samples collected over the innershelf of Gopalpur coast have revealed two significant depositional environments viz beach and dune. Sediment samples from water depth of < ... -
The biology of Nausitora hedleyi (Schepman) in the Cochin backwaters
(Delhi: Hindustan Pub. Co, 1973)The tropical estuarine shipworm Nausitora hedleyi is a highly destructive species in the Cochin backwaters, Kerala, India. In this area this species occurs throughout the year, during the course of which the salinity of ... -
Organic carbon in sediments of the southwestern margin of India: Influence of productivity and monsoon variability during the Late Quaternary
(Geological Society of India, 2007)The texture, organic carbon (OC), CaC03 and Rock-Eval parameters of the sediments from two gravity cores collected at depths below the oxygen minimum zone (OMZ) of the southwestern margin of India are presented and compared ... -
Fate of Enteromorpha flexuosa (Wulfen) J. Agardh and its spores in darkness: Implications for ballast water management
(Elsevier, 2007)Effects of darkness on the filaments and spores of a marine alga, Enteromorpha flexuosa (Wulfen) J. Agardh was evaluated through incubation experiments. Sporulation in the algal filaments was observed even after dark ... -
Eutrophication status of marine environment of Mumbai and Jawaharlal Nehru ports
(Springer, 2007)The marine environment of Mumbai and Jawaharlal Nehru ports was monitored for some environmental and biological parameters during three different periods between 2001 and 2002. The results are compared with the records ... -
Effect of ageing on survival of benthic diatom propagules
(Elsevier, 2007)A comparison of viable benthic diatom propagules based on the observations recorded immediately and after 5 years of ageing at 5oC is presented. The number of viable benthic diatom propagules decreased with ageing. However, ... -
