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 ... -
Sediment dynamics of an artificially deepened mesotidal coastal lagoon: An environmental magnetic investigation of Tauranga Harbour, New Zealand
(Elsevier, 2017)Tauranga Harbour, New Zealand�s largest barrier-enclosed coastal lagoon, comprises two sub-basins with separate catchments, inlets and tidal channel systems. This study sets out to assess and investigate the sediment ... -
Trichodesmium blooms and warm-core ocean surface features in the Arabian Sea and the Bay of Bengal
(Elsevier, 2017)Trichodesmium is a bloom-forming, diazotrophic, non-heterocystous cyanobacteria widely distributed in the warmer oceans, and their bloom is considered a �biological indication� of stratification and nitrogen limitation in ... -
Hydrothermal Alteration Promotes Humic Acid Formation in Sediments: A Case Study of the Central Indian Ocean Basin
(Wiley, 2018)Anomalously high concentrations of humic?rich dissolved organic matter (DOM) in extant submarine hydrothermal vent plumes traveled far from source are increasingly being reported. This DOM, able to mobilize trace metals ... -
Spatial variability of upper ocean POC export in the Bay of Bengal and the Indian Ocean determined using particle-reactive 234 Th
(Wiley, 2017)The northern Indian Ocean is globally significant for its seasonally reversing winds, upwelled nutrients, high biological production, and expanding oxygen minimum zones. The region acts as sink and source for atmospheric ... -
Potential ballast water transfer of organisms from the west to the east coast of India: Insights through on board sampling
(Elsevier, 2018)The possibility of translocation of organisms via ship's ballast water (BW) during a voyage from Hazira on the west coast to Visakhapatnam on the east coast of India was assessed. Samples of BW during the voyage and discharge ... -
Changes in standing stock and vertical distribution of benthic foraminifera along a depth gradient (58-2750�m) in the southeastern Arabian Sea
(Springer, 2018)Benthic foraminifera are a reliable proxy to reconstruct past oceanographic conditions. The ecological preferences of benthic foraminifera are usually studied from the core-top samples. The habitat of living benthic ... -
On the accuracy of assessing copepod size and biovolume using FlowCAM and traditional microscopy
(CSIR, India, 2017)In this paper, based on the biovolume estimation of different genera of copepods, we present the fact that only the Area-based Diameter (ABD) algorithm of FlowCAM has the efficiency to measure the bio-volume of copepods ... -
Salinity stratification controlled productivity variation over 300 ky in the Bay of Bengal
(Nature Publishing Group, 2017)The unique hydrographic setting of the Bay of Bengal (BoB) makes it an ideal tropical marine system to study the influence of regional and global forcings on productivity and [CO2aq] through the late quaternary. Enormous ... -
Effects of benzo(k)fluoranthene, a polycyclic aromatic hydrocarbon on DNA damage, lipid peroxidation and oxidative stress in marine gastropod Morula granulata
(Taylor & Francis, 2017)Benzo(k)fluoranthene [B(k)F] is one of the widespread priority pollutants of polycyclic aromatic hydrocarbons that has been scarcely studied for exposure assessment. With studies reporting a high amount B(k)F in sediments ... -
