Mariniradius saccharolyticus gen. nov., sp. nov., a member of the family Cyclobacteriaceae isolated from marine aquaculture pond water, and emended descriptions of the genus Aquiflexum and Aquiflexum balticum
(International Union of Microbiological Societies, 2013)A novel marine, Gram-stain-negative, oxidase- and catalase- positive, rod-shaped bacterium, designated strain AK6 sup(T), was isolated from marine aquaculture pond water collected in Andhra Pradesh, India. The fatty acids ... -
Flavobacterium nitratireducens sp. nov., an amylolytic bacterium of the family Flavobacteriaceae isolated from coastal surface seawater
(International Union of Microbiological Societies, 2013)A novel Gram-negative, rod-shaped, non-motile bacterium, designated strain N1 sup(T), was isolated from a marine water sample collected from the sea shore, Bay of Bengal, Visakhapatnam, India. The strain was positive for ... -
Meiofauna-mangrove interaction: A pilot study from a tropical mangrove habitat
(Station Biologique de Roscoff, 2013)We studied meiofauna in the sediments and on the surface of roots of four mangrove vegetation types in Chorao island, Goa, Central West coast of India. A total of 14 taxa were recorded from the mangrove roots while 12 taxa ... -
A summer monsoon pump to keep the Bay of Bengal salty
(American Geophysical Union, 2013)The Bay of Bengal receives a large influx of freshwater from precipitation and river discharge. Outflow of excess freshwater and inflow of saltier water is required to prevent the bay from freshening. Relatively fresh water ... -
On the nature of meandering of the springtime western boundary current in the Bay of Bengal
(American Geophysical Union, 2013)We present evidence that the springtime western boundary current (WBC) in the Bay of Bengal is a continuous northward-flowing current from about 12 degrees N to 17 degrees N, which then separates from the coast at around ... -
Structures and mechanisms of the first-branch northward-propagating intraseasonal oscillation over the tropical Indian Ocean
(Springer, 2013)The first-branch northward-propagating intraseasonal oscillation (FNISO) over the tropical Indian Ocean (IO) often triggers the onset of the Asian summer monsoon. In this study we investigate the structures and mechanisms ... -
Record of carbonate preservation and the Mid-Brunhes climatic shift from a seamount top with low sedimentation rates in the Central Indian Basin
(John Wiley, 2013)In the present investigation, an age model of carbonate-rich cores from a seamount top in the Central Indian Basin (CIB) was constructed using both isotopic (sup(230)Th sub(excess), AMS sup(14)C, oxygen isotopes) and ... -
Authigenic Gypsum in Gas-Hydrate Associated Sediments from the East Coast of India (Bay of Bengal)
(Geological Society of China, 2013)Authigenic gypsum crystals, along with pyrite and carbonate mineralization, predominantly calcites were noticed in distinct intervals in a 32 m long piston core, collected in the gas hydrate-bearing sediments in the northern ... -
Bioconcentration of trace metals by Saccostrea cucullata (von Born 1778) from Andaman waters
(CSIR-NISCAIR, 2013)Assessment of trace metals (Zn, Cu, Fe, Pb and Ni) in water, sediment and an oyster, Saccostrea cucullata, was carried out in five stations around Port Blair. Concentration of these metals in water, sediment and the oyster ... -
Anisotropic amplitude variation of the bottom-simulating reflector beneath fracture-filled gas hydrate deposit
(American Geophysical Union, 2013)For the first time, we report the amplitude variation with angle (AVA) pattern of bottom-simulating reflectors (BSRs) beneath fracture-filled gas hydrate deposits when the effective medium is anisotropic. The common depth ... -
Geophysical signatures over and around the northern segment of the 85 degrees E Ridge, Mahanadi offshore, Eastern Continental Margin of India: Tectonic implications
(Elsevier, 2013)The nature and origin of the subsurface 85 degrees E Ridge in the Bay of Bengal has remained enigmatic till date despite several theories proposed by earlier researchers. We reinterpreted the recently acquired high quality ... -
Restoration scaling of seagrass habitats in the oceanic islands of Lakshadweep, India using geospatial technology
(Springer, 2013)Small isolated oceanic islands are renowned for endemic species and biological wealth. Many small island administrations all over the world face complex challenges in protecting their natural resources. Restoration of ... -
Salt intrusion study in Cochin estuary - Using empirical models
(CSIR-NISCAIR, 2013)Intensive measurements of salt intrusion are taken at high and low waters during spring and neap tide for each month respectively from June 2007 to May 2008. Salt intrusion length at high water varied from 10 km in monsoon ... -
Tropical storm off Myanmar coast sweeps reefs in Ritchie's Archipelago, Andaman
(Springer, 2013)The reefs in some islands of Andaman and Nicobar suffered severe damage following a tropical storm in the Bay of Bengal off Myanmar coast during 13-17 March 2011. Surveys were conducted at eight sites in Andaman, of which ... -
Assessment of MODIS-Aqua chlorophyll-a algorithms in coastal and shelf waters of the eastern Arabian Sea
(Elsevier, 2013)The use of ocean colour remote sensing to facilitate the monitoring of phytoplankton biomass in coastal waters is hampered by the high variability in absorption and scattering from substances other than phytoplankton. The ... -
Response of phytoplankton to nutrient enrichment with high growth rates in a tropical monsoonal estuary - Zuari estuary, India
(CSIR-NISCAIR, 2013)Present study is about the impact of macronutrient enrichment on phytoplankton biomass and community structure in a tropical monsoonal estuary. In situ experiments carried out during the pre-monsoon period (February-March ... -
Waiting for the deluge
(CSIR-NISCAIR, 1991)Evidences show that levels of the world's seas are gradually rising The article discusses the causes and effects of such a rise in the sea level on the earth The relation between increase in greenhouse gases and sea level ... -
Our changing coastlines
(CSIR-NISCAIR, 1989)Our coastlines keep alive the sense of continuing creation and of the relentless drive of life In recent years, much has been done both to understand the processes that underlie their creation and to exploit their environment ... -
Back-arc extension in the Andaman Sea: Tectonic and magmatic processes imaged by high-precision teleseismic double-difference earthquake relocation
(American Geophysical Union, 2013)The geometry, kinematics, and mode of back-arc extension along the Andaman Sea plate boundary are refined using a new set of significantly improved hypocenters, global centroid moment tensor (CMT) solutions, and high-resolution ... -
Degradation of barnacle nauplii: Implications to chitin regulation in the marine environment
(Springer, 2013)The exoskeleton of most invertebrate larval forms is made of chitin, which is a linear polysaccharide of beta (1→4)-linked N-acetylglucosamine (GlcNAc) residues. These larval forms offer extensive body surface for bacterial ...
