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 ... -
Changes in depositional environment of the Savitri (tropical) estuary, central west coast of India
(Springer Science and Business Media Deutschland GmbH, 2021)Transformation of coastal regions as a result of recent climate change and localised human influences is of concern. Thus, understanding of the changes that have already occurred, the processes responsible for these changes, ... -
Widespread occurrence of methane seeps in deep-water regions of Krishna-Godavari basin, Bay of Bengal
(Elsevier Ltd, 2021)Drilling/coring activities during NGHP-Expeditions 01 and 02 discovered significant gas hydrate deposits in the Krishna-Godavari (KG) basin, a proven petroliferous basin located along the eastern continental margin of ... -
Microbial community shifts along an estuarine to open ocean continuum
(Elsevier, 2021)The water bodies along a continuum from estuaries to open ocean display significant changes in their physical, chemical and biological characteristics. In the current study, we report the influence of such changes on the ... -
Implications of micro-plankton and micro-detritus on the food web in the largest monsoonal estuary along the west coast of India
(Elsevier Ltd, 2021)This study presents how seasonal hydrographical changes affect the size structure of the micro-plankton community and thereby the availability of micro-detritus in the Kochi backwaters (KBW). Advanced quantification of ... -
Biophysical implications of the freshwater influx over small spatial scale in the coastal waters along the southwest coast of India during the Southwest Monsoon
(Elsevier BV, 2021)This study in the coastal waters off Kochi along the southwest coast of India during the Southwest Monsoon (SWM) presents the biophysical implications of freshwater influx over a small spatial scale. Field sampling was ... -
Distribution of size-fractionated phytoplankton biomass from the anthropogenically stressed tropical creek (Thane creek, India)
(Elsevier BV, 2021)Size-based partitioning of phytoplankton biomass is a crucial determinant of the type of food web functioning in an aquatic ecosystem. Seasonal and spatial distribution of total as well as size-fractionated phytoplankton ... -
Total organic carbon and its role in oxygen utilization in the eastern Arabian Sea
(Elsevier Ltd, 2021)We report seasonal and temporal variation of total organic carbon (TOC) in the eastern Arabian Sea (AS). In comparison to the deep, TOC in the top 100 m showed spatial variation with higher concentrations towards northern ... -
Evaluation of the Physiological Bacterial Groups in a Tropical Biosecured, Zero-Exchange System Growing Whiteleg Shrimp, Litopenaeus vannamei
(Springer, 2021)To elucidate the individual and multiple roles of physiological bacterial groups involved in biogeochemical cycles of carbon, nitrogen, phosphorus and sulfur, the changes in the abundance of aerobic bacteria (heterotrophs, ... -
How does frontal age influence physiological status of bacteria: a case study from the Northeastern Arabian Sea
(Springer, 2021)Sea surface temperature fronts in the Northeastern Arabian Sea (NEAS) facilitate nutrient enhancement in the surface layers, resulting in high primary production. Such high production areas contribute to the accumulation ... -
Ecological relevance of high and low nucleic acid content bacteria in a monsoon influenced tropical estuary: Implications on the ?-Glucosidase activity
(Elsevier Masson, 2021)Heterotrophic bacteria that differ in their nucleic acid content are frequently observed in aquatic environments. However, their relevance and roles in organic matter utilization in monsoon-influenced tropical estuaries ... -
Generation, propagation and dissipation of internal tides on the continental shelf and slope off the west coast of India
(Elsevier Ltd, 2021)The present study focuses on the dynamics of M2 internal tides on the shelf and slope off the west coast of India (WCI) using a high-resolution (1/48�) numerical ocean circulation model configured for the eastern Arabian ... -
Surface wave interactions with submerged horizontal viscoelastic sheets
(Elsevier, 2021)In this study, the surface wave interactions with submerged horizontal viscoelastic sheets of varying rheological properties are investigated both experimentally and analytically. In the experiments, we adopt the novel ... -
Pseudonocardia cytotoxica sp. nov., a novel actinomycete isolated from an Arctic fjord with potential to produce cytotoxic compound
(Springer, 2021)Herein we report the isolation of a novel actinomycete, strain MCCB 268T, from the sediment sample collected from a high Arctic fjord Kongsfjorden. MCCB 268T showed greater than 97% 16S rRNA gene sequence similarity with ... -
Release of significant fraction of primary production as dissolved organic carbon in the Bay of Bengal
