Denaturing gradient gel electrophoresis profiling of bacterial communities composition in Arabian Sea
(Triveni Enterprises, 2011)Denaturing gradient gel electrophoresis (DGGE) was used to elucidate spatial and temporal variations in bacterial community composition (BCC) from four locations along the central west coast of India. DNA extracts from 36 ... -
Primary description of surface water phytoplankton pigment patterns in the Bay of Bengal
(Elsevier, 2011)Spatial and temporal variations in surface water phytoplankton pigment distribution in the Bay of Bengal were studied during the spring intermonsoon (SpIM, February–April) and the commencement of the summer monsoon (CSM, ... -
Mysids (Crustacea) from the Exclusive Economic Zone of India with description of a new species
(Taylor & Francis, 2011)Mysid crustaceans, representing 27 species belonging to 21 genera, are reported from the Exclusive Economic Zone (EEZ) of India; one of these species, Pseuderythrops abrahami sp. nov., is described as new. The new species ... -
Dating of the 85 degrees E Ridge (northeastern Indian Ocean) using marine magnetic anomalies
(Current Science Association, 2011)The 85 degrees E Ridge is a typical aseismic ridge in the northeastern Indian Ocean in view of the fact that it associates with exceptional gravity and magnetic signatures. The ridge possesses two different gravity anomalies: ... -
Assessment of impacts and vulnerability to India's coastline due to climate change
(Current Science Association, 2011)India’s recently concluded second National Communications Project, co-ordinated by the MoEF involved participation of about 130 institutions spread over the country. A summary of these reports are expected to be prepared ... -
Response of west Indian coastal regions and Kavaratti lagoon to the November-2009 tropical cyclone Phyan
(Springer, 2011)Response of the coastal regions of eastern Arabian Sea (AS) and Kavaratti Island lagoon in the AS to the tropical cyclonic storm `Phyan’, which developed in winter in the south-eastern AS and swept northward along the ... -
Coupling of dimethylsulfide oxidation to biomass production by a marine flavobacterium
(American Society for Microbiology, 2011)Dimethylsulfide (DMS) is an important climatically active gas. In the sea, DMS is produced primarily by microbial metabolism of the compatible solute dimethylsulfoniopropionate. Laboratory growth of Bacteroidetes with DMS ... -
Regeneration and abnormality in benthic foraminifer Rosalina leei: Implications in reconstructing past salinity changes
(Universita' degli Studi di Milano, 2011)A laboratory culture experiment has been conducted to assess the response of marginal marine benthic foraminifer Rosalina leei to salinity and associated pH changes. Live specimens of Rosalina leei were subjected to a range ... -
High CO2 emissions from the tropical Godavari estuary (India) associated with monsoon river discharges
(American Geophysical Union, 2011)Estuaries have been under sampled to establish them as sources or sinks of the atmospheric carbon dioxide. Such poor coverage is well known for tropical, particularly monsoon driven, estuaries. In an attempt to study the ... -
Guest editorial for the special issue ‘‘Tectonics of Bay of Bengal and Arabian Sea with special emphasis on coastal and marine geohazards’’
(Springer, 2011)The main objective of the Special Issue entitled 'Tectonics of Bay of Bengal and Arabian Sea with special emphasis on coastal and marine geohazards' is to bring together the recent research work carried out on marine ... -
Anti-bacterial compounds from the sponge Haliclona sp.
(New Delhi: Oxford & IBH, 1992)The crude methanolic extract of the sponge Haliclona sp., collected off Gujarat coast exhibited promising anti-viral (in vitro, 75%) and anti-bacterial properties Partitioning of the extract between various organic solvents, ... -
Occurrence of the spider crab Acanthonyx euryseroche, a seaweed associate along the central west coast of India
(Current Science Association, 2011)Acanthonyx euryseroche has been reported for the first time from the Arabian Sea and thus, the genus Acanthonyx from India now comprises two species. The poor abundance and restricted occurrence in the harbour regions are ... -
Global equatorial sea-surface temperatures over the last 150,000 years: An update from foraminiferal elemental analysis
(Current Science Association, 2011)Solar insolation changes are amongst various factors that affect sea-surface temperature (SST) which in turn modulate global climate. Out of all the oceanic regions, equatorial region receives the maximum solar insolation ... -
An experiment towards characterizing seahorse sound in a laboratory controlled environment
(Department of Electronics and Telecommunication-Goa College of Engineering, 2011)There are many reports of sounds produced by Seahorse (Hippocampus), however, little is known about the mechanism of sound production. Here, we investigate sound produced by the seahorse during feeding. We attempt to try ... -
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 ... -
