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
(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 ... -
Sagar Kanya Bathymetric High Complex: An extinct giant submarine volcanic caldera in the Eastern Arabian Sea?
(Elsevier B.V., 2021)The marine geophysical investigations carried out in the Eastern Arabian Sea revealed the presence of a bathymetric high feature, referred to as the Sagar Kanya Seamount. The preliminary morphology and geophysical ... -
Microplastics in seafood as an emerging threat to marine environment: A case study in Goa, West coast of India
(Elsevier BV, 2021)The present study exhibits the occurrence of MPs in different matrices (water, sediment and biota) from the Sal estuary, Goa, situated on the central west coast of India. The average numbers of MPs in the water column and ... -
A numerical investigation on the tide-induced residence time and its association with the suspended sediment concentration in Gulf of Khambhat, northern Arabian Sea
(Elsevier Ltd, 2021)A 2D-numerical model is used to estimate suspended sediment (SS) transport and residence time (RT) of the Gulf of Khambhat (Gulf). Tidal current, as well as bottom topography, play a key role in sediment entrapment inside ... -
Sea foam-associated pathogenic bacteria along the west coast of India
(Springer Science and Business Media Deutschland GmbH, 2021)Anthropogenic activities release effluents containing nutrients and pathogenic bacteria that change the characteristics of coastal ecosystems. An important type of marine pollution which has occurred in 3 different states ... -
Inconsistent change in surface hydrography of the eastern Arabian Sea during the last four glacial-interglacial intervals
(Cambridge University Press (CUP), 2020)The eastern Arabian Sea is influenced by both the advection of upwelled water from the western Arabian Sea and winter convective mixing. Therefore, sediments collected from the eastern Arabian Sea can help to understand ... -
Cellular response of Brevibacterium casei #NIOSBA88 to arsenic and chromium- a proteomic approach
(Springer, 2020)Cellular response against different heavy metal stress differs with the metal. Arsenic and chromium are heavy metals and toxic to living systems. The concentration of these metals in seawater is very low. However, due to ... -
A late Pleistocene sedimentation in the Indus Fan, Arabian Sea, IODP Site U1457
(Cambridge University Press, 2020)The intensity of turbidite sedimentation over long timescales is driven by sea-level change, tectonically driven rock uplift and climatically modulated sediment delivery rates. This study focuses on understanding the effect ... -
Impact of a large hydraulic barrage on the trace metals concentration in mesozooplankton in the Kochi backwaters, along the Southwest coast of India
(Elsevier Ltd, 2020)This study delineates the impact of a man-made hydrological barrage [Thannermukkom barrage (TB)] on the concentration of selected trace metals (Fe, Zn, Cu, Co, Cr, Mn, Ni, Pb) in mesozooplankton from the Kochi backwaters ... -
Denitrification rates of culturable bacteria from a coastal location turning temporally hypoxic
(Elsevier B.V., 2020)Nitrate reduction plays a key role in the biogeochemical dynamics and microbial ecology of coastal upwelling systems. Seasonal upwelling in the eastern Arabian Sea entrains nitrate rich waters to the surface, the intense ... -
Progression of regeneration in demosponge Cinachyrella cf cavernosa based on wound location
(Springer, 2020)In this study, the differential regeneration process in sponge Cinachyrella cf cavernosa (Lamarck, 1815) was examined by creating wounds at basal and apical tissues. The differences in wound healing were investigated based ... -
Can the ecological status of three differentially impacted monsoonal tropical estuaries in NW India, be adequately assessed by a common estuarine benthic index?
