Perceptive of the pyroxene-bearing micrometeorites and their relation to chondrites
(John Wiley & Sons, 2018)We studied 149 pyroxenes from 69 pyroxene-bearing micrometeorites collected from deep-sea sediments of the Indian Ocean and South Pole Water Well at Antarctica, Amundsen-Scott South Pole station. The minor elements in ... -
Carbonate delta drift: A new sediment drift type
(Elsevier, 2018)Based on high-resolution reflection seismic and core data from IODP Expedition 359 we present a new channel-related drift type attached to a carbonate platform slope, which we termed delta drift. Like a river delta, it is ... -
Numerical Modelling of Ballast Water Dispersion in Different Bioregions along the Coast of India
(ASEAN Committee on Science and Technology (COST), 2018)Aquatic organisms and pathogens may become major threats to the coastal and marine environment when introduced into a region beyond their natural distributions through ballast water (BW). Coastal currents induced by tides ... -
Signature of Indian Ocean Dipole on the western boundary current of the Bay of Bengal
(Elsevier, 2018)This study uses an unprecedented collection of 27 years of repeated eXpendable Bathy Thermograph (XBT) sections crossing the western and north-western boundaries of the Bay of Bengal (BoB). Our objective is to analyse the ... -
Role of eddies on intensity of oxygen minimum zone in the Bay of Bengal
(Elsevier, 2018)One of the strongest oxygen minimum zones (OMZ) in the world oceans occurs in the Bay of Bengal (BoB) with no systematic trends in dissolved oxygen (DO) since past half a century. An evaluation is made here to examine the ... -
Diversity of culturable nitrate-reducing bacteria from the Arabian Sea oxygen minimum zone
(Elsevier, 2018)The subsurface waters of the northern Arabian Sea display a pronounced oxygen minimum layer associated with high nitrite maxima which provide an ideal niche for organisms that can respire nitrate. Culture-based studies ... -
Influence of Darkness and Aging on Marine and Freshwater Biofilm Microbial Communities Using Microcosm Experiments
(Springer US, 2018)Ballast tank biofilms pose an additional risk of microbial invasion if sloughed off during ballasting operations, yet their significance and invasion biology is poorly understood. In this study, biofilms developed in marine ... -
Variability of terrigenous input to the Bay of Bengal for the last ~80 kyr: Implications on the Indian monsoon variability
(Springer Berlin, 2018)Oceanographic processes in the Bay of Bengal (BoB) are strongly impacted by south-westerly and north-easterly winds of the Indian monsoon system during the summer and winter respectively. Variations in calcium carbonate ... -
Mudbank off Alleppey, India: A bane for foraminifera but not so for carbon burial
(Elsevier, 2018)Calm conditions and extensive fishing, during monsoon season in the mudbank off Alleppey (Kerala), India creates a unique environment, associated with high suspended particulate matter. The effect of processes associated ... -
Crustal underplating and effective elastic plate thickness of the Laxmi Ridge, northern Arabian Sea
(Elsevier, 2018)Laxmi Ridge, a prominent basement high feature with negative gravity anomaly in the northern Arabian Sea, is generally considered as stretched continental crust. However, recently it is proposed that the ridge could be an ... -
Current Status and Decadal Growth Analysis of Krishna - Godavari Delta Regions using Remote Sensing
(Coastal Education and Research Foundation, 2018)Demarcation and continuous monitoring of shorelines are essential for understanding the dynamic nature and processes of the coastal areas. Shorelines of delta regions are ecologically and economically sensitive and dynamic. ... -
Ballast Water Risk Assessment: the Indian experience
(ASEAN Committee on Science and Technology (COST), 2018)The Ballast Water Risk Assessment serves as a �Decision Support System� for any given port to take appropriate ballast water management actions. Risk assessment involves collation of data from the ballast water reporting ... -
Sea Level Interannual Variability Along the West Coast of India
(John Wiley & Sons, 2018)Interannual sea level anomalies (SLA), and the related thermocline variations, along the west coast of India (WCI) strongly impact the ecosystems, fisheries, and potentially the monsoon rainfall. Here we investigate the ... -
Efflux Pump-Mediated Quorum Sensing: New Avenues for Modulation of Antimicrobial Resistance and Bacterial Virulence
(Springer, Singapore, 2018)Bacterial pathogenesis is frequently enhanced by virulence mechanisms that facilitate growth. Such virulence factors include biofilm formation and antimicrobial resistance mechanisms. One primary resistance mechanism ... -
Population characteristics of Villorita cyprinoides in Vembanad Lake, India
(Taylor & Francis, 2018)The Vembanad Lake system (VLS), the largest Ramsar site in India, faces a major ecological crisis because of reclamation. The lake ranks first in the production of the black clam (Villorita cyprinoides). In this study, we ... -
Macroalgal Functional Genomics: A Missing Area
(Springer International Publishing, Cham, 2017)Functional genomics may be defined as the study of deciphering the function and regulation of genes for various traits. Functional genomics has made significant advances in decoding functionality of gene(s) and their ... -
Numerical simulation of the observed near-surface East India Coastal Current on the continental slope
(Springer Berlin Heidelberg, 2018)We simulate the East India Coastal Current (EICC) using two numerical models (resolution� 0.1-�0.1-),� an oceanic general circulation model (OGCM) called Modular Ocean Model and a simpler, linear, continuously stratified ... -
Role of epibiotic diatoms isolated from the barnacle shell in the cyprid metamorphosis of Balanus amphitrite
(Springer International Publishing, 2018)Barnacle shell (BSh)-associated bacteria, their culture supernatants (CS), and biofilm exopolymers (BE) are known to induce cyprid metamorphosis of Balanus amphitrite. Besides bacteria, the BSh also harbors diatoms. However, ... -
Evidences of CO2 Leakage During the Last Deglaciation: The Need to Understand Deep-ocean Carbonate Chemistry of the Arabian Sea
(Geological Society of India, India, 2018)It is generally accepted view that the ventilation of Southern Ocean during the last deglaciation was the key factor in atmospheric CO2 rise. Further, other sites were identified, like the western equatorial Pacific, the ... -
