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 ...
Implications of REE incorporation and host sediment influence on the origin and growth processes of ferromanganese nodules from Central Indian Ocean Basin
(Elsevier, 2021)
This study presents new major, trace and REE data for thirty-five ferromanganese nodules recovered from areas representing three different sediment types (siliceous, red clay and their transition zone) in the Central Indian ...
Copepods size structure in various phases of a cold-core eddy - Normalised Abundance Size Spectra (NASS) approach.
(Pergamon, 2020)
The present study addresses the copepods size structure in different phases of a cold-core eddy based on a 17 day time-series measurement (21st February to 8th March 2016) from a coastal site in the western Bay of Bengal ...
Sources of organic matter and tracing of nutrient pollution in the coastal Bay of Bengal
(Pergamon, 2020)
Stable isotopic composition of carbon (delta13CPOM) and nitrogen (delta15NPOM) in the particulate organic matter (POM) is used to identify sources of organic carbon and nutrients using monthly time-series observation in ...
