Controls on greigite preservation in a gas hydrate system of the Krishna-Godavari basin, Bay of Bengal
(Springer Verlag, 2020)Shallow sediments across large parts of Krishna-Godavari (K-G) basin offshore east central Indian contain abundant methane and gas hydrates. In this study, we carried out rock-magnetic and transmission electron microscope ... -
Contrasting sulfidization in the turbidite and hemipelagic sediments of Bengal Fan
(Elsevier Ltd, 2020)We report for the first time, contrasting sulfidization profiles in a sedimentary sequence comprising of clay-silt turbidites and hemipelagic dominated deposits in a channel-levee complex of the middle Bengal Fan. The ... -
Inhibition of pathogenic Vibrio harveyi using calamenene, derived from the Indian gorgonian Subergorgia reticulata, and its synthetic analog
(Springer, 2020)We report the synthesis and antimicrobial properties of a partially reduced dihydronathphthoquinone analogue of 2-methoxy, 5-acetoxy calamenene, extracted from Subergorgia reticulata. The growth of a pathogenic Vibrio ... -
A revisit to the regulation of oxygen minimum zone in the Bay of Bengal
(Springer, 2020)Occurrence of intense oxygen minimum zone (OMZ) is known in the Bay of Bengal (BoB), but it has been recently reported to have become more acute and is at its tipping point. Here, we show that the intensification of OMZ ... -
Building Capacity and Resilience Against Diseases Transmitted via Water Under Climate Perturbations and Extreme Weather Stress
(Springer, Cham, 2020)It is now generally accepted that climate variability and change, occurrences of extreme weather events, urbanisation and human pressures on the environment, and high mobility of human populations, all contribute to the ... -
Interannual changes of austral summer coccolithophore assemblages and southward expanse in the Southern Indian Ocean
(Elsevier Ltd, 2020)Coccolithophore ecology and biogeography in the Southern Indian Ocean was studied during the austral summer of 2009 (SOE09; late austral summer), 2010 (SOE10; mid-austral summer), and 2012 (ISEA12; early austral summer). ... -
Phytoplankton characterisation in the Alappuzha mud banks during the pre-/post phases of a red-tide, Prorocentrum shikokuense Hada
(Elsevier, 2020)The short-term changes in hydrochemical and phytoplankton characteristics occurring in the Alappuzha mud bank (AMB) region, located on the southwest coast of India, were monitored in association with a red-tide event caused ... -
Regional Study of Changes in Wind Power in the Indian Shelf Seas over the Last 40 Years
(MDPI AG, 2020)Wind power variations at two heights (the surface level and turbine hub level) were investigated at 20 locations in the shelf seas of India using hourly fifth generation European Centre for Medium-Range Weather Forecasts ... -
Spatio-temporal variation in the macrobenthos of Paradip port, east coast of India
(Current Science Association, IAS, 2020)The spatio-temporal variation in the abundance and community structure of macrobenthic invertebrates, which are useful ecological indicators, was assessed along with associated environmental settings and sediment characteristics ... -
Changes in the ballast water tank bacterial community during a trans-sea voyage: Elucidation through next generation DNA sequencing
(Academic Press, 2020)Ballast water (BW) mediated bioinvasion is one of the greatest threats to the health of aquatic ecosystems. Bacteria, unlike higher organisms, are transferred in large numbers through BW. Owing to their abundance and ... -
Hourly maximum individual wave height in the Indian shelf seas-its spatial and temporal variations in the recent 40 years
(Springer, 2020)The spatial and temporal variability of the high individual wave heights, which pose a hazard in India's shelf seas, has not been investigated. In this study, the spatial and temporal variation of hourly maximum individual ... -
Aerobic microbial communities in the sediments of a marine oxygen minimum zone
(Oxford University Press (OUP), 2020)The ecology of aerobic microorganisms is never explored in marine oxygen minimum zone (OMZ) sediments. Here we reveal aerobic bacterial communities along ~3�m sediment-horizons of the eastern Arabian Sea OMZ. Sulfide-containing ... -
Variable protein expression in marine-derived filamentous fungus Penicillium chrysogenum in response to varying copper concentrations and salinity
(Royal Society of Chemistry (RSC), 2020)Copper is one of the essential trace dietary minerals for all living organisms, but is potentially toxic at higher concentrations, mainly due to the redox reactions in its transition state. Copper is one of the essential ... -
Applications of Prodigiosin Extracted from Marine Red Pigmented Bacteria Zooshikella sp. and Actinomycete Streptomyces sp.
(MDPI AG, 2020)This study is aimed to determine the distribution, diversity and bioprospecting aspects of marine pigmented bacteria (MPB) isolated from pristine Andaman Islands, India. A total of 180 samples including seawater, sediment, ... -
Maintenance of the southern Bay of Bengal cold pool
(Elsevier, 2020)The region of relatively cooler water, sitting in the shadow zone of monsoon rainfall, around southern tip of India and around Sri Lanka, is known as the cold pool. A ship-board observations program to the east of Sri Lanka ... -
Response of the Bay of Bengal to 3-7-Day Synoptic Oscillations During the Southwest Monsoon of 2019
(American Geophysical Union (AGU), 2020)The satellite-derived precipitation over central India (73-78�E, 20-25�N) during the 2019 southwest monsoon season reveals that high-amplitude 3-7-day synoptic oscillations dominated the other intraseasonal oscillations ... -
