River discharge as a major driving force on spatial and temporal variations in zooplankton biomass and community structure in the Godavari estuary India
(Springer, 2017)Variability in horizontal zooplankton biomass distribution was investigated over 13 months in the Godavari estuary, along with physical (river discharge, temperature, salinity), chemical (nutrients, particulate organic ... -
Abundance and Ecology of Endemic Asterorotalia trispinosa from the Western Bay of Bengal: Implications for its Application as a Paleomonsoon Proxy
(Wiley, 2017)A total of 97 surface sediment samples were collected from the continental shelf and slope of the western Bay of Bengal to assess the potential application of Asterorotalia trispinosa as a paleomonsoon proxy. The relative ... -
Antagonistic interactions of sponge-associated Actinobacteria against heterotrophic bacteria from sponge and ambient water
(Current Science Association, IAS, 2017)In the present study, 11 sponge-associated Actinobac-teria showed 316 inhibitory interactions against 75 heterotrophic bacteria as each Actinobacteria inhibit-ed the growth of >1 bacterial isolates from the sponge and ... -
Evaluation of the impact of bioaccumulation of PAH from the marine environment on DNA integrity and oxidative stress in marine rock oyster (Saccostrea cucullata) along the Arabian sea coast
(Springer, 2017)Marine pollution due to oil spills is of great concern globally for their impact on the health of marine ecosystems. We assessed the genotoxic effects and oxidative stress due to genotoxic pollutants accumulated from the ... -
Processes controlling the accelerated warming of the Arabian Sea
(Wiley, 2018)The Arabian Sea (AS) has undergone a regime shift after 1995, manifesting the disruption of its natural decadal cycle over-riding a secular rise in its sea surface temperature (SST). Using a suite of in situ and remote ... -
Variation of Bacterial Metabolic Rates and Organic Matter in the Monsoon-Affected Tropical Estuary (Godavari, India)
(Taylor & Francis, 2017)Bacteria play a central role in the oxidation of organic matter. In tropical estuaries, bacterial metabolic rates and carbon modification are regulated by physicochemical changes influenced by the annual monsoon-mediated ... -
70 kyr record of denitrification and oxygenation changes in the eastern Arabian Sea
(Geochemical Society of Japan, 2017)A 70 kyr record of ?15N from the eastern Arabian Sea, Core AAS9/21 was investigated. High ?15N values during interglacials and low ?15N values during glacials are documented, which mimics the global ?15N records in the ... -
Stable isotope (C-O-S) and geochemical studies of auriferous quartz carbonate veins, Neoarchaean orogenic Ajjanahalli and Gadag Gold Field, Chitradurga schist belt, Dharwar Craton, southern India: Implication for the source of gold mineralizing fluids
(Elsevier, 2018)Carbon (?13CPDB) and oxygen (?18OSMOW) isotopic compositions of carbonates of auriferous quartz-carbonate veins (QCVs), S-isotope (?34SCDT) composition of gold bearing sulphide minerals and REE geochemical characteristics ... -
Viral-Induced Mortality of Prokaryotes in a Tropical Monsoonal Estuary
(Frontiers, 2017)Viruses are recognized as the most abundant and dynamic biological entities in the marine and estuarine environment. However, studies on the dynamics and activity of viruses in transient estuarine systems are limited. This ... -
Differential Protein Analysis of Hexavalent Chromium Stress Response in Marine Staphylococcus xylosus
(Bentham Science, 2018)Several bacteria tolerate chromate with this attribute important in bacteria intended for biotechnological applications on chromate clean-up. Marine bacteria are beginning to show promise in this field due to their range ... -
Improved Sprouting and Growth of Mung Plants in Chromate Contaminated Soils Treated with Marine Strains of Staphylococcus Species
(Springer, 2017)Marine bacteria possess a wide variety of bioremediation potential which is beneficial environmentally and economically. In this study, bacterial isolates from marine waters were screened for tolerance and growth in high ... -
Bio-prospecting of coral (Porites lutea) mucus associated bacteria, Palk Bay reefs, Southeast coast of India
(Elsevier, 2017)Coral mucus is one of the key localization in the coral holobiont, as this serves as an energy rich substrate for a wide range of abundant, diverse and multifunctional microbiota. However, very little is known about the ... -
Genotoxicity of two heavy metal compounds: lead nitrate and cobalt chloride in Polychaete Perinereis cultrifera
(Springer, 2017)The present study explores the in vivo and in vitro genotoxic effects of lead nitrate, [Pb(NO3)2] a recognized environmental pollutant and cobalt chloride (CoCl2), an emerging environmental pollutant in polychaete Perinereis ... -
Variability of the date of monsoon onset over Kerala (India) of the period 1870-2014 and its relation to sea surface temperature
(Springer, 2017)Monsoon onset over Kerala (India) which occurs every year is a major climatic phenomenon that involves large scale changes in wind, rainfall and sea surface temperature (SST). Over the last 150 years, the date of monsoon ... -
Resilience potential of an Indian Ocean reef: an assessment through coral recruitment pattern and survivability of juvenile corals to recurrent stress events
(Springer, 2017)Coral reefs are degraded by the synergistic action of climate and anthropogenic stressors. Coral cover in the Palk Bay reef at the northern Indian Ocean largely declined in the past decade due to frequent bleaching events, ... -
On the dynamics of the Sri Lanka Dome in the Bay of Bengal
(Wiley, 2017)East of Sri Lanka, in the northern Indian Ocean, a cold dome, known as the Sri Lanka Dome (SLD), develops during southwest monsoon season (June-September). The SLD first forms around May, matures in July, and decays around ... -
U enrichment and Th/U fractionation in Archean boninites: Implications for paleo-ocean oxygenation and U cycling at juvenile subduction zones
(Pergamon, 2018)Phanerozoic boninites record enrichments of U over Th, giving Th/U: 0.5-1.6, relative to intraoceanic island arc tholeiites (IAT) where Th/U averages 2.6. Uranium enrichment is attributed to incorporation of shallow, ... -
Dynamics of Andaman Sea circulation and its role in connecting the equatorial Indian Ocean to the Bay of Bengal
(Wiley, 2017)Circulation in the Bay of Bengal (BoB) is driven not only by local winds, but are also strongly forced by the reflection of equatorial Kelvin waves (EKWs) from the eastern boundary of the Indian Ocean. The equatorial ... -
Diagnosis of the diatom community upon biofilm development on stainless steels in natural freshwater
(Hindawi, 2017)This paper reports the development of biofilms on stainless steels (SS) upon exposure in a natural freshwater ecosystem for about six months and focuses on the composition of diatom populations. By using environmental ... -
