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 ... -
Modern Radiolarians Recovered from the Mudline Samples at IODP-341 Sites in the South Alaska Basin, North East Pacific Ocean
(Springer, Cham, 2020)The Integrated Ocean Drilling Program (IODP) Expedition 341 drilled the 5 sites (U1417-U1421) across the Surveyor channel near the Aleutian trench in the Gulf of Alaska to study the sedimentation during middle Miocene to ... -
Sedimentary organic matter composition from tropical ports with distinct geographic and morpho-hydrodynamic characteristics: Evaluation through multiple biochemical markers
(Elsevier Ltd, 2020)Increasing coastal urbanization and shipping activity-related environmental pollution advocate the importance of assessment of port ecosystems. Fatty acid biomarkers, elemental components, and biopolymers were used to ... -
Iron organic speciation during the LOHAFEX experiment: Iron ligands release under biomass control by copepod grazing
(Elsevier B.V., 2020)The LOHAFEX iron fertilization experiment consisted in the fertilization of the closed core of a cyclonic eddy located south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean. This eddy was characterized ... -
Novel Coronavirus (Covid-19): A Review on Epidemiology, Pathophysiology, Molecular Mechanism, Therapeutic Evidence and Preventive Measures
(Oriental Scientific Publishing Company, Bhopal, Madhya Pradesh, India, 2020)Currently, the deadly disease COVID-19 was exponentially spread across the world as a pandemic outbreak caused by a novel coronavirus, termed as SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2). In this view, ... -
Spatio-temporal Variations in Bacterial Abundance with an Emphasis on Fecal Indicator Bacteria and Vibrio spp. in and around Visakhapatnam Port, East Coast of India
(UGM Press, 2020)The ecological health of port environments, which are dynamic and hotspots of anthropogenic activities, can be analyzed using specific pathogenic bacteria as they provide definite evidence and source of pollution. The ... -
Influence of environmental parameters on bio-optical characteristics of colored dissolved organic matter in a complex tropical coastal and estuarine region
(Elsevier BV, 2020)Dissolved organic matter (DOM) is an important source of carbon in aquatic ecosystems, and colored DOM (CDOM), which is smaller than 0.2 mu m and interacts with ultraviolet (UV) and visible light, affects the spectral ... -
Fish composition and assemblage structure in tropical monsoonal estuaries: Estuarine use and feeding guild approach
(Elsevier BV, 2020)The structure of fish guilds was analysed in four tropical monsoonal estuaries, namely Zuari, Mandovi, Terekhol and Kali, along India�s western coast. The fish were sampled from 2017 to 2019 both temporally and spatially: ... -
A deep-sea hydrogen peroxide-stable alkaline serine protease from Aspergillus flavus
(Springer Science and Business Media Deutschland GmbH, 2020)We report here the production of an alkaline serine protease by Aspergillus flavus isolated at 5600-m depth from deep-sea sediments of the Central Indian Basin. When grown on defatted groundnut oil meal at 30��C for 48-72�h, ... -
Scanning Electron Microscopic Studies of Fossil Pteropods from the Andaman Sea: Inferences on Carbonate Dissolution
(Indian National Science Academy, 2020)Among the different microfossils group, pteropods are least studied zooplanktons having delicate aragonitic shells which are very susceptible to dissolution. The present study has been carried out to understand the effect ... -
Diversity of culturable Sulphur-oxidising bacteria in the oxygen minimum zones of the northern Indian Ocean
(Elsevier B.V., 2020)Oxygen minimum zones (OMZs) are unique, widely spread and well-studied features of the global ocean, varying in seasonality and intensity. The Northern Indian Ocean contains OMZs in the Arabian Sea (AS-OMZ) and the Bay of ... -
Bay of Bengal Sea surface salinity variability using a decade of improved SMOS re-processing
(Elsevier Inc., 2020)Monsoon rain and rivers bring large freshwater input to the Northern Bay of Bengal (BoB), yielding low Sea Surface Salinity (SSS) after the monsoon. The resulting sharp upper-ocean salinity stratification is thought to ... -
