Mesozooplankton distribution near an active volcanic island in the Andaman Sea (Barren Island)
(Springer, 2011)The study addresses the distribution and diversity of mesozooplankton near the active volcano-Barren Island (Andaman Sea) in the context of persistent volcanic signature and warm air pool existing for the last few months. ... -
Eutrophication induced changes in benthic community structure of a flow-restricted tropical estuary (Cochin backwaters), India
(Springer, 2011)The influence of anthropogenic loading on the distribution of soft bottom benthic organisms of a tropical estuary (Cochin backwaters) was examined. The industrial activities were found to be high in the northern and central ... -
Enumeration of bacteria from a Trichodesmium spp. bloom of the eastern Arabian Sea: Elucidation of their possible role in biogeochemistry
(Springer, 2011)The carbon-flux via algal bloom events involves bacteria as an important mediator. The present study, carried out during the spring inter-monsoon month of April 2008 onboard CRV Sagar Manjusha-06 in the Eastern Arabian ... -
Geochemical implications of gabbro from the slow-spreading Northern Central Indian Ocean Ridge, Indian Ocean
(Cambridge University Press, 2011)Gabbro samples (c. < 0.4 Ma old) dredged from close to the ‘Vityaz Megamullion’ on the slow-spreading Northern Central Indian Ridge (NCIR, 18-22 mm yr sup(-1)) include mostly olivine gabbro and Fe-Ti oxide gabbro. The ... -
A study on bacteria associated with the intestinal tract of farmed yellow seahorse, Hippocampus kuda (Bleeker, 1852): Characterization and extracellular enzymes
(Springer, 2011)The microenvironment of bacteria associated with the gastrointestinal tract of an animal influences the host in many ways, including the metabolism of several nutrients. Isolation, molecular characterization and enzymatic ... -
Simple electric powered plankton wheel for the production of aggregates in seawater on-board ship
(NISCAIR, CSIR, 2011)A new handy plankton wheel was devised for use on-board a ship. Its efficacy to generate aggregates was tested on land using coastal waters. The device successfully generated aggregates of sizes varying up to 11.3 mm sup(2) ... -
Effect of varying frontal systems on stable oxygen and carbon isotopic compositions of modern planktic foraminifera of Southern Ocean
(Current Science Association, 2011)Studies have been carried out in the Atlantic and Pacific sectors of the Southern Ocean regarding the movement of its fronts (water-masses boundaries) with changing climate and other oceanic parameters. But the Indian ... -
The effect of bacteria on diatom community structure - The 'antibiotics' approach
(Elsevier, 2011)To investigate the effect of bacteria on diatoms at the community level, sediment samples from an intertidal tropical environment were treated with penicillin (a Beta-lactam antibiotic that can affect diatoms only through ... -
Investigation of XBT and XCTD biases in the Arabian Sea and the Bay of Bengal with implications for climate studies
(American Meteorological Society, 2011)Long time series of XBT data in the Bay of Bengal and the Arabian Sea are valuable datasets for exploring and understanding climate variability. However, such studies of interannual and longer-scale variability of temperature ... -
Accumulation of sediment, organic matter and trace metals with space and time, in a creek along Mumbai coast, India
(Elsevier, 2011)Two core sediment samples; one from inner part (ManI) and the other closer to the mouth (ManII; were collected from the intertidal regions of Manori, a tidally influenced creek near Mumbai, India. Both the cores were ... -
Some aspects of pollution of coastal marine environment of Bombay
(National Institute of Oceanography, Goa, India, 1994)Unprecedented population growth and industrial development around Bombay Harbour and Thana Creek (Together termed as Bay) coupled with heavy port traffic and other port activities have imposed considerable strain on the ... -
Heavy metal burden in coastal marine sediments of north west coast of India in relation to pollution
(National Institute of Oceanography, Goa, India, 2009)Human activities in the marine zone of India are mainly confined to the inner shelf where water depths are <50 m. Considering the vastness of the coastal area, the data on contaminants including metals in seawater, marine ... -
Probable movement and mixing of contaminants in tidal estuaries - A field study in Kundalika Estuary, west coast of India
(Scientific Publishers, 2001)The probable movement and mixing of contaminants within and through the Kundalika river estuary along the west coast of India are studied Neutrally buoyant biplane drogues, floats and dye were tracked at different stages ... -
Micrometer- and nanometer-sized platinum group nuggets in micrometeorites from deep-sea sediments of the Indian Ocean
(The Meteoritical Society, 2011)We examined 378 micrometeorites collected from deep-sea sediments of the Indian Ocean of which 175, 180, and 23 are I-type, S-type, and G-type, respectively. Of the 175 I-type spherules, 13 contained platinum group element ... -
Bacterial response to contrasting sediment geochemistry in the central Indian Basin
(International Association of Sedimentologists, 2011)In order to investigate whether geochemical, physiographic and lithological differences in two end-member sedimentary settings could evoke varied microbe-sediment interactions, two 25 cm long sediment cores from contrasting ... -
Changing climate and microbial resources in polar realms
(Learning in Geography, Humanities, Technology and Science (LIGHTS), 2011)The current climate changes that we are experiencing is attributable to both natural and man made causes. Either way it would be pertinent to be able to assess the impact at various levels to help us prepare for the ... -
Statistical significance of biomonitoring of marine algae for trace metal levels in a coral environment
(Taylor & Francis, 2011)Samples of macro algae collected at random distances from the coral and near shore environment of Lakshadweep archipelago were analyzed for their trace metal content (Fe, Mn, Zn, Cu, Co, Cr, Cd, Pb, and Ni). All the species ... -
