Fatty acids as indicators of sediment organic matter dynamics in a monsoon-influenced tropical estuary
(Elsevier, 2021)Sedimentary organic matter (OM) composition serves as a biomarker and helps in hindcast analysis of the events in the habitat. The present study was carried out on a monthly basis to evaluate the contribution of different ... -
Ocean impact on the intensification of cyclone Titli
(Springer, 2021)Tropical cyclones are the most devastating weather events which still needs to understand much due to the uniqueness in their paths and intensification locations. One such recent very severe cyclonic storm, Titli, is ... -
34S enrichment as a signature of thiosulfate oxidation in the " Proteobacteria "
(Oxford University Press (OUP), 2021)Kinetics of thiosulfate oxidation, product, and intermediate formation, and 34S fractionation, were studied for the members of Alphaproteobacteria Paracoccus sp. SMMA5 and Mesorhizobium thiogangeticum SJTT, the Betaproteobacteria ... -
Applications of SPOT-7 tri-stereo imagery in deriving the surface topography and mass changes of glaciers in Indian Himalaya
(Taylor and Francis, 2021)The present study describes the application of satellite images of SPOT 7, acquired on 10 October 2014 for producing the high spatial resolution digital elevation models of five glaciers in the Indian Himalaya. For data ... -
Elevated acidification rates due to deposition of atmospheric pollutants in the coastal Bay of Bengal
(AGU Wiley, 2021)Human inputs of pollutants to the atmosphere and subsequent deposition may decrease pH in the coastal waters. Significant rate of decrease in pH and increase in pCO2 by 3-5 times is noticed in the coastal Bay of Bengal ... -
Acute toxicity of two organophosphorus pesticides to the early-life stage of flathead grey mullet, Mugil cephalus (Linnaeus, 1758)
(CSIR-NISCAIR, 2021)The acute toxicity (96 h LC50) of two organophosphorus pesticides (OPs), chlorpyrifos (CPF) and dimethoate (DMT) to the early-life stage (fry) of flathead grey mullet, Mugil cephalus (total length, 22�2 mm, wet weight, ... -
Bacterial and fungal diversity in sediment and water column from the abyssal regions of the Indian Ocean
(Frontiers Media S.A., 2021)The deep sea is the largest environment on Earth, comprising important resources of commercial interest. It is composed of a wide variety of ecosystems, which is home to often unique organisms that are yet to be described. ... -
Phytoplankton communities in marine intertidal rock-pools: Effect of location, geometric shapes and allelopathy
(Springer, 2021)Biologically rich rock-pools (RPs) are prominent component of rocky intertidal habitat and this study elucidates the factors aAecting the phytoplankton distribution from high-tide (HT), mid-tide (MT) and low-tide (LT) RPs ... -
Sound speed variation in the coastal waters off Cochin and signature of subsurface maxima
(Springer, 2021)We investigated the vertical and horizontal variation of the sound speed using the Thermodynamic Equation Of Seawater-2010 (TEOS-10) and monthly CTD observations at Cochin estuary and adjacent coastal waters (inlet to 20 ... -
Evolution mechanism of contrasting phases of consecutive IOD events from 1994 to 1998
(CSIR-NISCAIR, 2021)The Dipole Mode Index (DMI), an Index used to represent the Indian Ocean Dipole (IOD), shows a back to back occurrence of positive and negative IOD events during the period 1994 to 1998. The year 1994 was a strong positive ... -
Response of the bacterial metagenome in port environments to changing environmental conditions
(Elsevier, 2021)Port environments are highly dynamic and hotspots for marine bioinvasion. This study investigated the bacterial diversity at two geographically distant ports (Mangalore-marine port; and Haldia-riverine port) using ... -
Sedimentation rate and organic matter dynamics shape microbiomes across a continental margin
(European Geosciences Union, 2021)Marine sedimentation rate and bottom-water O2 concentration control organic carbon remineralization and sequestration across continental margins, but whether and how they shape microbiome architecture (the ultimate effector ... -
Seasonality of macrobenthic assemblages and the biotic environmental quality of the largest monsoonal estuary along the west coast of India
(Springer, 2021)This study deals with the macrobenthic assemblages and the biotic environmental quality of Kochi backwaters (KBW), India. Due to the heavy river discharge, extensive limnetic and turbid conditions prevailed in the KBW ... -
Comparative assessment of amino acids composition in two types of marine fish silage
(Nature Publishing Group, 2021)Fish silage is a brown liquefied product achieved by the action of enzymes when finely grounded whole/parts of either single or mixed fish types are subjected to acidification. This study made a comparative assessment of ... -
Spectral peak wave period climatology and its relationship with natural climate variability over the Bay of Bengal
(Springer, 2021)The predominance of swells or wind-seas at a location can be inferred from the spectral peak wave period (Tp). The present study examines the climatology of Tp and its variability in the Bay of Bengal (BoB) during the last ... -
Implications of an extensive salt water barrage on the distribution of black clam in a tropical estuarine system, Southwest coast of India
(Elsevier, 2021)Based on a monthly field sampling over a year in the Kochi backwaters (KBW), this study presents the larval ecology of black clam and discusses how an extensive saltwater barrage [Thannermukkom barrage (TB)] impacted the ... -
Role of river discharge and warming on ocean acidification and pCO2 levels in the Bay of Bengal
(Taylor and Francis, 2021)Shifts in surface ocean pCO2 and pH are important controls governing global climate. Based on the linear relationship of observed surface pH and pCO2 with sea surface temperature (SST), sea surface salinity (SSS) and ... -
Cyclone Hudhud-eddy induced phytoplankton bloom in the northern Bay of Bengal using a coupled model
