Microbial dynamics in a tropical monsoon influenced estuary: Elucidation through field observations and microcosm experiments on biofilms
(Elsevier, 2017)The changes that occur in biofilms reflect the influence of the environment. In a case study, the biofilms developed along a salinity gradient from marine to freshwater in a tropical monsoon influenced estuary (Zuari, west ... -
40Ar/39Ar dating of the Mumbai tholeiites and Panvel flexure: intense 62.5 Ma onshore-offshore Deccan magmatism during India-Laxmi Ridge-Seychelles breakup
(Oxford University Press, 2017)Mumbai, located on the western Indian continental margin, exposes Danian-age Deccan magmatic units of diverse compositions, dipping seaward due to the Panvel flexure. The Ghatkopar-Powai tholeiitic sequence contains ... -
Metabolic regulatory oscillations in intertidal green seaweed Ulva lactuca against tidal cycles
(Nature Publishing Group, 2017)The survival of wetland plant species largely relies on physiological adaptations essential for submergence and desiccation. Intertidal seaweeds, unlike terrestrial plants, have unique adaptations to submergence and can ... -
Quick elucidation of cyclodepsipeptide sequence from sacoglossan Elysia grandifolia using electrospray ionisation-tandem mass spectrometry
(Sage Publications, 2017)Butanol fraction of sacoglossan Elysia grandifolia was investigated for identifying peptides using electrospray ionisation-tandem mass spectrometry (ESI-MS/MS). Without prior isolation, the structural determination is ... -
POC export fluxes in the Arabian Sea and the Bay of Bengal: A simultaneous 234Th/238U and 210Po/210Pb study
(Elsevier, 2018)Seasonal variation in POC export flux, from the upper ocean, was studied during post southwest monsoon (October-November 2013) and spring intermonsoon (May 2014) at selected locations in the central and southern Arabian ... -
Wave-current interaction during Hudhud cyclone in the Bay of Bengal
(Copernicus Publications for EGU, 2017)The present work describes the interaction between waves and currents utilizing a coupled ADCIRC+SWAN model for the very severe cyclonic storm�Hudhud,�which�made landfall at Visakhapatnam on�the east coast of India in ... -
Oceanospirillum sanctuarii sp. nov., isolated from a sediment sample
(Microbiology Society, 2017)A novel Gram-staining-negative, spiral-shaped, pale-yellow, non-sporulating, motile, aerobic bacterium, designated strain AK56T, was isolated from a sediment sample collected at the Coringa Wildlife Sanctuary, India. ... -
Influence of spatial competitor on asexual reproduction of the marine sponge Cinachyrella cf. cavernosa (Porifera, Demospongiae)
(Springer, 2018)Competition for resources, which often results in resource tradeoffs, is intense among sessile benthic organisms. In this investigation, we tested the tradeoffs between the primary and secondary functions by studying the ... -
Weight-length relationship and Fulton�s condition factor of the alligator pipefish, Syngnathoides biaculeatus (Bloch, 1785) from the Southeast coast of India
(Current Science Association, IAS, 2017)The present study provides information on weight- length relationship (WLR) and Fulton�s condition factor (K) of the alligator pipefish, Syngnathoides biaculeatus (Bloch, 1785) sampled from Palk Bay (PB) and Gulf of Mannar ... -
Perennial occurrence of heterotrophic, indicator and pathogenic bacteria in the coastal Bay of Bengal (off Visakhapatnam) - Impact of physical and atmospheric processes
(Elsevier, 2018)In order to examine the health of the coastal waters off Visakhapatnam in terms of prevalence and abundance of heterotrophic (H), indicator and pathogenic (P) bacterial counts (BC) and influence of physical processes on ... -
Immune response of the short neck clam Paphia malabarica to salinity stress using flow cytometry
(Elsevier, 2017)Paphia malabarica is a predominant and commercially important bivalve in India, persistently challenged by wavering salinity in a monsoon-influenced estuary. To examine the organism's immunological response under such a ... -
Sponge-associated bacterium, Yangia pacifica: a potential candidate for bioremediation of azo dyes
(Current Science Association, IAS, 2017)The bioremediation potential of bacteria associated with the sponge Cinachyrella cavernosa on azo dyes, Amido black and Congo red is reported. Twenty four percent of the bacteria decolourized these dyes at 50 mg l -1 ... -
Seasonal and interannual changes of significant wave height in shelf seas around India during 1998-2012 based on wave hindcast
(Pergamon, 2018)Present study examines the interannual changes of significant wave height (Hs) in shelf seas around Indian mainland based on the 15-year (1998-2012) wave hindcast data obtained from numerical model. Validation of the ... -
Influence of elevated temperature, pCO2, and nutrients on larva-biofilm interaction: Elucidation with acorn barnacle, Balanus�amphitrite Darwin (Cirripedia: Thoracica)
(Elsevier, 2017)Selection of optimal habitat by larvae of sessile organism is influenced by cues offered by the biofilm. Ocean warming and acidification are likely to enforce changes in the biofilm community and inturn influence the ... -
Physical control of interannual variations of the winter chlorophyll bloom in the northern Arabian Sea
(Copernicus Publications for EGU, 2017)The northern Arabian Sea hosts a winter chlorophyll bloom, triggered by convective overturning in response to cold and dry northeasterly monsoon winds. Previous studies of interannual variations of this bloom only relied ... -
Variability of the Somali Current and eddies during the southwest monsoon regimes
(Elsevier, 2017)The meso-scale eddies and currents in the Arabian Sea are analyzed using different satellite observations, Simple Oceanic Data Assimilation (SODA) reanalysis, and Ocean Reanalysis System 4 (ORAS4) from 1993 to 2016 to ... -
