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 ... -
New records of epibiont ciliates Thecacineta urceolata and Acinetides gruberi (Ciliophora: Suctorea) from the Indian coast
(CNRS - Station Biologique de Roscoff - ABiMS, Roscoff, France, 2020)This article deals with the report of two suctorian ciliates species viz. Thecacineta urceolata Liao and Dovgal, 2015 and Acinetides gruberi Curds, 1985 as epibionts on nematode and harpacticoid copepod respectively from ... -
Spatio-temporal Coastal Morphological Changes of Godavari Delta Region in the East Coast of India
(Coastal Education and Research Foundation, 2020)Understanding the characteristics of coastal morphology is necessary to analyse the causes of its changes and its consequences. The present study focuses on the satellite-derived and in-situ measurement based changes along ... -
The Oxygen Isotope Compositions of Large Numbers of Small Cosmic Spherules: Implications for Their Sources and the Isotopic Composition of the Upper Atmosphere
(American Geophysical Union (AGU), 2020)Cosmic spherules are micrometeorites that melt at high altitude as they enter Earth’s atmosphere and their oxygen isotope compositions are partially or completely inherited from the upper atmosphere, depending on the ... -
In vivo evaluation of microbial cocktail of microalgae-associated bacteria in larval rearing from zoea I to mysis I of the Indian white shrimp, Penaeus indicus
(Springer, 2020)The present work aimed to explore the efficacy of microbial cocktail of microalgae-associated bacteria, such as Alteromonas sp. Mab 25, Labrenzia sp. Mab 26, Marinobacter sp. Mab 18 and Marinobacter sp. Mab 34, on survival, ... -
Increased Ventilation of the Northern Indian Ocean during the Last Deglaciation
(Springer, 2020)This paper gives an overview of the deep-water ventilation studies carried out over the world oceans using radiocarbon. There is a consensus that aged water mass existing in the abyssal ocean during the last glacial, ... -
A new species of the genus Corynophrya (Ciliophora: Suctorea) from the west coast of India, Arabian Sea
(CNRS - Station Biologique de Roscoff - ABiMS, Roscoff, France, 2020)The article presents the description of a new species of the suctorian genus Corynophrya inhabiting the body surface (cuticle) of harpacticoid copepod from the west coast of India, Arabian Sea. The diagnosis of the genus ... -
Environmental influence on the picophytoplankton community structure in the central and northern Bay of Bengal
(Elsevier, 2020)The Bay of Bengal (BoB) is a low productive, oligotrophic ecosystem. The picophytoplankton (Pico; < 3mu m) play a significant role in the biogeochemistry of such ecosystems. The information on the Pico is exiguous from ... -
Magnetic Mineral Diagenesis in a Newly Discovered Active Cold Seep Site in the Bay of Bengal
(Frontiers Media SA, 2020)Diagenetically formed magnetic minerals at marine methane seep sites are potential archive of past fluid flow and could provide important constraints on the evolution of past methane seepage dynamics and gas hydrate formation ... -
Diversity and Functional Patterns of Benthic Amphipods in the Coralline Intertidal Zones of a Marine National Park, India
(Frontiers, 2020)Coralline intertidal habitats of marine protected areas (MPAs) are important model systems to investigate species diversity and ecological functioning of benthic communities. Spatial variability of amphipod species composition ... -
Massive coral bleaching in the patchy reef of Grande Island, along the eastern Arabian Sea during the 2015/16 global bleaching event
(Elsevier B.V., 2020)The 2014-2017 mass bleaching event is considered the third massive coral global bleaching event in recorded history. Based on the National Oceanic and Atmospheric Administration�s (NOAA) Coral Reef Watch (CRW) product ... -
Terrestrial and marine bioluminescent organisms from the Indian subcontinent: a review
(Springer Science and Business Media Deutschland GmbH, 2020)The inception of bioluminescence by Harvey (1952) has led to a Nobel Prize to Osamu Shimomura (Chemistry, 2008) in biological research. Consequently, in recent years, bioluminescence-based assays to monitor toxic pollutants ... -
Provenance tracing of long-range transported dust over the Northeastern Arabian Sea during the southwest monsoon
