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 ...
Variability of dissolved oxygen in the Arabian Sea Oxygen Minimum Zone and its driving mechanisms
(2020)
The Arabian Sea hosts one of the most intense, perennial Oxygen Minimum Zones (OMZ) in the world ocean. Observations along a meridional transect at 68°E extending from 8 to 21°N showed large seasonal as well as interannual ...
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 ...
Aberrations in the microbiome of cyanobacteria from a tropical estuary polluted by heavy metals
(Elsevier Ltd, 2020)
The effect of heavy metal pollution on the microbiome of cyanobacteria in Cochin estuary (CE) on the southwest coast of India is reported in the study. Statistically significant difference in heavy metal concentration was ...
