Bioconversion of chitin and concomitant production of chitinase and N-acetylglucosamine by novel Achromobacter xylosoxidans isolated from shrimp waste disposal area
(Nature Research, 2020)Marine pollution is a significant issue in recent decades, with the increase in industries and their waste harming the environment and ecosystems. Notably, the rise in shellfish industries contributes to tons of shellfish ... -
Tectonic appraisal of the Mid-Thane Creek of Mumbai, India: An integrated geophysical approach
(Springer, 2020)Integrated geophysical surveys, comprising marine magnetic, high resolution shallow seismic and single-beam bathymetry were conducted to assess subsurface tectonics of the Mid-Thane Creek (MTC) of Mumbai. The bathymetry ... -
Characterizing three shallow-water locations off Goa, India, using passive acoustic data
(Acoustical Society of America (ASA), 2020)In this study, an analysis of the passive acoustic data is carried out for the quantitative characterization of shallow-water acoustic environments from three major estuarine systems of Goa during the months of March and ... -
Effect of undulating bottom on wave interaction with a floating flexible plate coupled with a flexible porous barrier
(Springer, 2020)In the present study, under the assumption of small amplitude water wave theory and structural response, effect of bed undulation on the wave interaction with a combination of flexible porous barrier and a flexible floating ... -
Hilbert-Huang transform analysis of surface wavefield under tropical cyclone Hudhud
(Elsevier Ltd, 2020)The characteristics of an evolving ocean surface wavefield under tropical cyclone Hudhud that took place in October 2014 are investigated. The Hilbert-Huang transformation (HHT) is used for the spectral analysis of the ... -
Extending the limit of widespread dispersed Toba volcanic glass shards and identification of new in-situ volcanic events in the Central Indian Ocean Basin
(Springer, 2020)We report the widespread extent of Toba volcanic glass shards in the Central Indian Ocean Basin. Investigation of four sediment cores (7o-17oS) revealed several shard-rich horizons (SRH) that provide the first detailed ... -
A roadmap to IndOOS-2: Better observations of the rapidly-warming Indian Ocean
(American Meteorological Society, 2020)The Indian Ocean Observing System (IndOOS), established in 2006, is a multinational network of sustained oceanic measurements that underpin understanding and forecasting of weather and climate for the Indian Ocean region ... -
Autonomous profiling float observations reveal the dynamics of deep biomass distributions in the denitrifying oxygen minimum zone of the Arabian Sea
(Elsevier B.V., 2020)Data from 13 autonomous profiling BGC-Argo floats, equipped with biogeochemical and bio-optical sensors deployed between 2011 and 2016, were used to explore the potential of bio-optical methods to map deep biomass distribution ... -
Salmonella Contamination of Seafood in Landing Centers and Retail Markets of Mumbai, India
(Oxford University Press (OUP), 2020)Background: Seafood contamination with Salmonella enterica is not only a public health concern, but can also lead to economic losses due to import rejections. Continuous monitoring of seafood for Salmonella is necessary ... -
Watercraft depicted in the art of Odisha, East Coast of India
(Australasian Institute for Maritime Archaeology, 2018)The Indian state of Odisha, with its long coastline facing the Bay of Bengal, extensive riverine network and convenient anchorages, has enjoyed a sustained maritime history. Nevertheless, the lack of archaeological excavation ... -
Pyrone-derived Marine Natural Products: A Review on Isolation, Bio-activities and Synthesis
(Bentham Science Publishers Ltd., 2020)Marine natural products (MNPs) containing pyrone rings have been isolated from numerous marine organisms, and also produced by marine fungi and bacteria, particularly, actinomycetes. They constitute a versatile structure ... -
Influence of salinity stress on bacterial diversity from a marine bioinvasion perspective: evaluation through microcosm experiments
(Current Science Association, IAS, 2020)Mid-ocean ballast water exchange has been used since the past few years to control bioinvasion through ballast water (BW), which requires the ship to exchange part of its BW in the open ocean. The change in salinity is ... -
Massive Nitrogen Loss Over the Western Indian Continental Shelf During Seasonal Anoxia: Evidence From Isotope Pairing Technique
(Frontiers Media SA, 2020)The western Indian continental shelf houses the world's largest naturally formed coastal low-oxygen zone that develops seasonally during the summer monsoon. We investigated multiple reductive nitrogen transformation pathways ... -
Signals of selection in the mitogenome provide insights into adaptation mechanisms in heterogeneous habitats in a widely distributed pelagic fish
(Nature Research, 2020)Oceans are vast, dynamic, and complex ecosystems characterized by fluctuations in environmental parameters like sea surface temperature (SST), salinity, oxygen availability, and productivity. Environmental variability acts ... -
The impacts of ocean acidification on marine trace gases and the implications for atmospheric chemistry and climate
(Royal Society Publishing, 2020)Surface ocean biogeochemistry and photochemistry regulate ocean-atmosphere fluxes of trace gases critical for Earth�s atmospheric chemistry and climate. The oceanic processes governing these fluxes are often sensitive to ... -
