Superimposition of wind seas on pre-existing swells off Goa coast
(Elsevier, 2011)An analysis of wind and wave data collected in the coastal region of Goa, west coast of India, during fair weather season reveals a distinct and systematic diurnal variation in wind speed, wave height and wave period, ... -
Fungal community analysis in the deep-sea sediments of the central Indian Basin by culture-independent approach
(Springer, 2011)Few studies have addressed the occurrence of fungi in deep-sea sediments, characterized by elevated hydrostatic pressure, low temperature, and fluctuating nutrient conditions. The diversity of fungi at three locations of ... -
Tiniest primary producers in the marine environment: An appraisal from the context of waters around India
(Current Science Association, 2011)Phytoplankton (0.2 mm - 2 mm) are the major primary producers in the marine environment thereby forming a basic link in the marine food web. They are categorized into different groups depending on their size range. Cells ... -
Ancient maritime trade of the eastern Indian littoral
(Current Science Association, 2011)Before the discovery of the monsoon winds by Hippalus in AD 45–47, the mariners of the east coast of India were aware of the monsoon wind and currents and used them for maritime trade. The maritime trade from India to ... -
Geostrophic volume transport and eddies in the region of sub-tropical and sub-Antarctic waters south of Madagascar during austral summer (January–February) 2004
(Current Science Association, 2011)Geostrophic volume transport based on hydrographic data is estimated across two transects that are covered south of Madagascar in the region of the sub-tropical and sub-Antarctic waters as a part of the Indian Pilot ... -
G model revisited: Seasonal changes in the kinetics of sulphate-reducing activity in the salterns of Ribander,Goa India
(Taylor & Francis, 2011)The evaluate the contribution of Sulphate-Reducing Bacteria (SRB) to the carbon flux from marine salterns, sulfate reducing activity (SRA) was measured for a year (Sep 2000-Aug 2001). This covered the pre-monsoon period ... -
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
