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 ...
Phthalic acid esters - A grave ecological hazard in Cochin estuary, India
(2020)
Distribution and ecological risks of Phthalic acid esters (PAEs) are poorly studied in estuarine environments in India. An attempt is made to chart the sources and assess the ecological risk of six PAE congeners (Σ6PAEs), ...
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 ...
Functional and taxonomic (? and ?) diversity patterns of macrobenthic communities along a depth gradient (19-2639 m): A case study from the southern Indian continental margin
(Elsevier Ltd, 2020)
Identifying the drivers that shape the biodiversity of a region is important to predict the response of ecosystems to environmental changes. Macrofaunal distribution pattern in the North Indian Ocean has so far been mainly ...
Degradation of tarballs using associated bacterial consortia
(Springer, 2020)
Tarballs are semi-solid blobs of crude-oil formed in marine environment. Microbial degradation of tarballs is poorly understood, though there are indications that tarball-associated microbes can degrade recalcitrant ...
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 ...
Release of significant fraction of primary production as dissolved organic carbon in the Bay of Bengal
(Elsevier Ltd, 2021)
Despite nutrients supply through river discharge, atmospheric deposition and eddy-driven mixing, low primary production in the Bay of Bengal (BoB) is attributed to light limitation and non-availability of nutrients during ...
