Stress and toxicity of biologically important transition metals (Co, Ni, Cu and Zn) on phytoplankton in a tropical freshwater system: An investigation with pigment analysis by HPLC
(Elsevier, 2010)Stress and toxicity of four biologically important transition metals (Co, Ni, Cu and Zn) on phytoplankton in Godavari River (a tropical freshwater system) were studied to understand the fate of phytoplankton of freshwater ... -
Differences in carbohydrate profiles in batch culture grown planktonic and biofilm cells of Amphora rostrata Wm. Sm
(Taylor & Francis, 2010)Diatoms are abundant in biofilms developed on surfaces immersed in sunlit waters. In both the planktonic and the biofilm mode of growth, diatoms produce carbohydrate polymers which perform several functions including ... -
Decolorization of synthetic dyes and textile effluents by basidiomycetous fungi
(Springer, 2010)Decolorization of six synthetic dyes and two raw textile effluents (A and B) by eight basidiomycetous fungi was investigated. Among eight basidiomycetous fungi, fungal isolate RCK-1 decolorized textile effluent A maximally ... -
Diatom community dynamics in a tropical, monsoon-influenced environment: West coast of India
(Elsevier, 2010)Diatom communities are influenced by environmental perturbations, such as the monsoon system that impact the niche opportunities of species. To discern the influence of the monsoon system on diatom community structure, we ... -
Shift in detrital sedimentation in the eastern Bay of Bengal during the late Quaternary
(Indian Academy of Sciences, 2010)Down-core variations of granulometric, geochemical and mineral magnetism of a 70-cm long sediment core retrieved from the eastern Bay of Bengal abyssal region were studied to understand sedimentation pattern and sediment ... -
Short-term variability in halocarbons in relation to phytoplankton pigments in coastal waters of the central eastern Arabian Sea
(Elsevier, 2010)Halocarbons released from oceans are known to be important in the atmospheric processes. Their abundance in seawater is influenced by water column conditions and phytoplankton community. In the present study halocarbon ... -
Geochemical and mineralogical analysis of stone anchors from west coast of India: Provenance study using thin sections, XRF and SEM-EDS
(Elsevier, 2010)Stone anchors have been recovered along the Indian coast as a part of the maritime archaeological studies at the National Institute of Oceanography (NIO), Goa, India. Study of stone anchors provides clues to understand the ... -
Optimization of alkaline cellulase production by the marine-derived fungus Chaetomium sp. using agricultural and industrial wastes as substrates
(Walter de Gruyter, 2010)Alkaline cellulases were screened from 54 fungal isolates obtained from mangrove leaves and mangrove wood litters as endophytes and wood litter fungi, respectively. Only three fungal isolates tested positive for alkaline ... -
Immobilization of nickel by bacterial isolates from the Indian Ridge system and the chemical nature of the accumulated metal
(Taylor & Francis, 2010)Bacterial isolates from Carlsberg-Ridge waters were tested for their ability to immobilize Ni. For this, test cultures were suspended for 60 d in seawater with and without added Ni at concentrations of 10 to 10,000 mu M. ... -
Extension of Gundlakamma River Fault over eastern continental margin of India
(Current Science Association, 2010)The bathymetry, magnetic and shallow seismic data were collected between the water depths of 13 to 26 meters north of Ongole to study the tectonic significance of Gundlakamma river towards offshore. The bathymetry in the ... -
November 2009 tropical cyclone Phyan in the eastern Arabian Sea: Oceanic response along west India coast and Kavaratti lagoon
(IEEE, 2010)Spatial and temporal response of the coastal waters of eastern Arabian Sea (AS) and Kavaratti lagoon to the tropical cyclonic storm 'Phyan', which developed in the southeastern AS and swept northward along the eastern AS ... -
New polyhydroxy sterols from the marine sponge Callyspongia fibrosa (Ridley & Dendly)
(Elsevier, 2010)Four new polyhydroxylated sterols are isolated from Marine sponge Callyspongia fibrosa collected from the Gulf of Mannar, western Bay of Bengal (India). The structural assignment is based on sup(1)H and sup(13)C NMR spectra. ... -
Impact of internal waves on sound propagation off Bhimilipatnam, east coast of India
(Elsevier, 2010)Internal waves (IW) are identified off Bhimilipatnam, east coast of India, from the time series CTD (hourly interval)and thermistor chain data (2 min interval) collected during 23-25 Feb 2007.The measurements were carried ... -
Observed intra-seasonal to interannual variability of the upper ocean thermal structure in the southeastern Arabian Sea during 2002-2008
(Elsevier, 2010)The southeastern Arabian Sea (SEAS), located in the Indian Ocean warmpool, is a key-region of the regional climate system. It is suspected to play an important role in the dynamics of the Asian summer monsoon system. The ... -
Anthropogenic effects on sediment quality offshore southwestern Taiwan: Assessing the sediment core geochemical record
(Elsevier, 2010)Slag material was dumped in two sites off southwestern Taiwan by the China Steel Corporation during 1984-1995. By geochemically analyzing four sediment cores, the impact of slag on the sediment chemistry is investigated. ... -
Role of hydrology in the formation of Co-rich Mn crusts from the equatorial N Pacific, equatorial S Indian Ocean and the NE Atlantic Ocean
(The Society of Resource Geology, 2010)Co-rich Mn crusts from four different locations of the world ocean have been studied to understand the role of dissolved oxygen of the ambient seawater in the formation of Co-rich Mn crusts. WOCE (World Ocean Circulation ... -
