Rock magnetic evidence of tectonic control on the sedimentation and diagenesis in the Andaman Sea over ~1 million years
(Elsevier, 2021)We evaluate the sedimentary (magnetic, mineralogical, geochemical, grain size) records of a long sediment core (NGHP-01-17 A) to elucidate the tectonic control on the sedimentation and diagenesis in the Andaman Sea (AS) ... -
Isolation and Identification of Tyrosinase Inhibitors from Marine Algae Enteromorpha sp
(Bentham Science Publishers, 2021)The extract of marine green algae Enteromorpha sp. was evaluated in vitro for inhibitory activity against mushroom tyrosinase enzyme. The principle active agents i.e. coumarin; 4-hydroxycoumarin (1) and two sterols; ... -
Evaluating the Bacterial Diversity from the Southwest Coast of India Using Fatty Acid Methyl Ester Profiles
(Springer, 2021)The fatty acid composition of bacterial isolates remains stable under standardized culture conditions, which makes it a useful taxonomic marker. The present study aims to characterize the diversity and quantity of fatty ... -
A Spatial Ecological Study Based on Benthic Foraminifera off Central West Coast of India: An Approach through Cluster Analysis with Special Reference to Oxygen Minimum Zone
(Springer, 2021)Fifty-two surface samples collected from a depth range between 15 and 3300�m from the Vijaydurg-Karwar sector off the central west coast of India were analyzed for benthic foraminifera. A total of 386 benthic foraminifera ... -
Controls of contrasting provenance and fractionation on the sediment magnetic records from the Bay of Bengal
(Elsevier, 2021)We present the results of rock magnetic, granulometric, microscopy and mineralogical analyses of shelf sediments off Krishna, Godavari, and Mahanadi Rivers, Bay of Bengal. The aim of the study was to assess the influence ... -
The maxima in northerly wind speeds and wave heights over the Arabian Sea, the Arabian/Persian Gulf and the Red Sea derived from 40 years of ERA5 data
(Springer, 2021)Recent studies point out the importance of northerly winds and waves in the Arabian Sea, especially those due to shamal and makran events in addition to the northeast monsoon system. We have analyzed climatology and trends ... -
The first record of the genus Lamellibrachia (Siboglinidae) tubeworm along with associated organisms in a chemosynthetic ecosystem from the Indian Ocean: A report from the Cauvery-Mannar Basin
(Springer Science and Business Media LLC, 2021)Here, we report for the first time, the genus Lamellibrachia tubeworm and associated chemosynthetic ecosystem from a cold-seep site in the Indian Ocean. The discovery of cold-seep was made off the Cauvery-Mannar Basin ... -
Ocean wave dynamics in the coastal area of the central west coast of India and its variability
(Elsevier, 2021)Examined the spatial and temporal changes in the wave spectra using waves measured in the coastal area at two locations for three years. Long-term variability is examined with ERA5 reanalysis data. The annual average wave ... -
Identification of wave systems in the multimodal sea state along the Indian shelf seas
(Springer, 2021)The coexistence of multiple wave systems generated locally and by remote storms is common in the ocean and its quantification is required in the design of marine facilities. This study identifies the multimodal sea states ... -
Multiple Drug-Resistant Vibrio Cholerae Responsible for Cholera Outbreak among Migrant Domestic Workers in Kerala, South India
(Multidisciplinary Digital Publishing Institute, 2021)Cholera outbreaks are prevalent in countries with a low Human Development Index (HDI) where people have limited access to safe drinking water, sanitation and hygiene (WASH). Intriguingly, the state of Kerala which records ... -
Probiotics inspired from natural ecosystem to inhibit the growth of Vibrio spp. causing white gut syndrome in Litopenaeus vannamei
(Springer Science and Business Media Deutschland GmbH, 2021)Probiotics inspired by host-microbe interactions in the natural ecosystem are propitious in controlling bacterial infections in aquaculture and veterinary systems. Here we report the isolation and characterization of ... -
Significantly dominant warm-core eddies: An ecological indicator of the basin-scale low biological production in the Bay of Bengal
(Elsevier B.V., 2021)This paper introduces the cumulative impact of cyclonic (cold-core) and anticyclonic (warm-core) eddies on the distribution of phytoplankton biomass in the Bay of Bengal (BoB). Estimations of the ocean surface eddy features ... -
Effect of alkyl chain length on the extraction properties of U and Th using novel CnmimNTf2 /isophthalamide systems
(Elsevier B.V., 2021)An attempt was made to investigate the structural modification of CnmimNTf2 ionic liquid in combination with a novel ligand, 5-bromo-N1,N3-bis(1-methyl-1H-pyrazol-3-yl)isophthalamide on the extraction properties of tetra ... -
Hydrological regulation of Vibrio dynamics in a tropical monsoonal estuary: a classification and regression tree approach
(Springer Science and Business Media Deutschland GmbH, 2021)Dynamics of Vibrio populations in aquatic environments are of concern, as they encompass members pathogenic to humans as well as marine flora and fauna. Spatiotemporal distribution of its culturable abundance for a range ... -
Distribution, contamination status and bioavailability of trace metals in surface sediments along the southwest coast of India
(Elsevier, 2021)This study investigates the influence of upwelling induced seasonal hypoxia in the sediment-water interface on the distribution, bioavailability and geochemical partitioning of selected trace metals in surficial sediments ... -
Tectono-magmatic evolution of Tethyan oceanic lithosphere in supra subduction zone forearc regime: Geochemical fingerprints from crust-mantle sections of Naga Hills Ophiolite
(Elsevier BV, 2021)The Naga Hills Ophiolite (NHO) belt in the Indo-Myanmar range (IMR) represents a segment of Tethyan oceanic crust and upper mantle that was involved in an eastward convergence and collision of the Indian Plate with the ... -
Evolution of wave spectra during sea breeze and tropical cyclone
(Elsevier Ltd, 2021)Wave spectral components change with time and through space by receiving energy from wind, through non-linear energy transfer among the spectral components and dissipation due to white-capping and friction. Changes in wave ... -
