Estuarine turbidity maximum in six tropical minor rivers, central west coast of India
(IWA Publishing, 2018)Understanding patterns of erosion and sedimentation and their driving mechanisms is important for formulating a variety of estuarine management issues (conservation, shoreline protection, navigation, dredging and embanking). ... -
Indian monsoon variability in the last 2000 years as inferred from benthic foraminifera
(Elsevier, 2018)The effect of ambient conditions on living (Rose-Bengal stained) benthic foraminifera has been studied from the shelf and slope of the central-western Bay of Bengal to assess the applicability of temporal changes in benthic ... -
Behaviour of trace metals in the anoxic environment of Veraval harbour, India
(Elsevier, 2018)The purpose of the present study is to investigate the behaviour of trace metals in anoxic environment. Water column of the harbour was found to be anoxic (DO <0.2mgl-1) with high concentration of NH4+-N (av. 459±21-moll-1) ... -
Ecological indications of copepods to oxygen-deficient near-shore waters
(Elsevier, 2018)Dissolved oxygen deficiency and its impacts on marine organisms is an important research topic world over. In this study, we utilized the advantage of a shallow seasonal hypoxic zone occurring along the Southwest Coast of ... -
River plume fronts and their implications for the biological production of the Bay of Bengal, Indian Ocean
(Inter-Research Science Center, Oldendorf/Luhe, Germany, 2018)Fronts are the physical interface between water masses of distinct hydrographic characteristics and are ubiquitous features of the Bay of Bengal (BoB). They form as a result of receiving high freshwater runoff from many ... -
Seasonal variations in the water quality of six tropical micro and meso-tidal estuaries, central west coast of India
(CSIRO PUBLISHING, 2018)Seasonal nutrient dynamics were investigated in four rivers with a microtidal range (Terekhol, Chapora, Sal and Talpona rivers) and were compared with those of two rivers with a mesotidal range (Zuari and Mandovi rivers) ... -
Survival in the dark: strategies adopted by Tetraselmis indica (Chlorodendrophyceae, Chlorophyta)
(Taylor & Francis, 2018)The adaptive strategy of Tetraselmis indica to survive darkness was evaluated over a period of 182 days. Resting cells formation and reduction in catabolic activity facilitated dark survival and their rejuvenation. The ... -
Potential of Marine-Derived Fungi to Remove Hexavalent Chromium Pollutant from Culture Broth
(Springer India, 2018)Chromium (Cr) released from industrial units such as tanneries, textile and electroplating industries is detrimental to the surrounding ecosystems and human health. The focus of the present study was to check the Cr(VI) ... -
Distribution and contamination status of phthalic acid esters in the sediments of a tropical monsoonal estuary, Cochin - India
(Elsevier, 2018)Phthalic acid esters (PAEs) are a group of endocrine-disrupting chemicals listed as priority pollutants by United States Environmental Protection Agency (USEPA, 2009). This study provides baseline information on seasonal ... -
Low light phytoplankton genera observed in the coastal and estuarine waters of Goa, India
(ALOKI Applied Ecological Research and Forensic Institute Ltd, 2018)This is the first study carried-out to understand the phytoplankton genera in the low light (less than 50 -mol/m2 /s of photosynthetically available radiation) for the estuarine and coastal waters of Goa, India. There were ... -
Mineralogical and geochemical variation in hydrothermal sulfides from Vienna Woods field, Manus Basin, Papua New Guinea: constraints on their evolution
(The Chinese Society of Oceanography, 2018)Polymetallic sulfides from two hydrothermal chimneys and talus deposit from the Vienna Woods field of Manus Basin were studied for mineralogy, elemental composition, and S-isotope ratio to understand their evolution. The ... -
Inverted sediments in the coastal Antarctic lake: Evidence of paleostorm?
(Elsevier, 2018)The faunal (foraminiferal and diatom abundance) and sedimentological analysis was carried out on two cores collected from a coastal lake in the Vestfold Hills region of Antarctica. Out of a couple of cores collected from ... -
Bacillus alkalilacus sp. nov., isolated from a sediment sample from a lake in India
(Microbiology Society, 2018)An aerobic, endospore-forming, haloalkali-tolerant, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK73T, was isolated from a sediment sample collected from Sambhar lake, Jaipur, Rajasthan, India. ... -
Salibacterium nitratireducens sp. nov., a haloalkalitolerant bacterium isolated from a water sample from Sambhar salt lake, India.
(Microbiology Society, 2018)A strictly aerobic, haloalkali-tolerant, Gram-stain-positive, non-motile, rod-shaped bacterium, designated strain SMB4T, was isolated from a water sample collected from Sambhar salt lake, Rajasthan, India. Growth occurred ... -
Magnetic tracing of sediment dynamics of mudbanks off southwest coast of India
(Springer Berlin Heidelberg, 2018)In this study, we utilized environmental magnetic in combination with sedimentological and hydrodynamic data to investigate the formative processes of mudbanks along southwest coast of India. We document the linkages between ... -
Virulence gene and antibiogram profile as markers of pathogenic Escherichia coli in tropical beaches of North Western India: Implications for water quality and human health
(Elsevier, 2018)The purpose of the present study was to investigate the presence of pathogenic Escherichia coli in anthropogenically marred tropical beaches of Mumbai, India. Out of 200 presumptive E. coli, (n-=-125) isolates were analysed ... -
Genesis of Central Indian Ocean basin seamounts: morphological, petrological, and geochemical evidence
(Springer Berlin Heidelberg, 2018)We present the petrological investigation carried out of the seamounts located between water depths of 4300 and 5385 m in the Central Indian Ocean Basin (CIOB). The seamounts have variable shapes (conical and elongated) ... -
A two million year record of low-latitude aridity linked to continental weathering from the Maldives
(2018)Indian-Asian monsoon has oscillated between warm/wet interglacial periods and cool/dry glacial periods with periodicities closely linked to variations in Earth�s orbital parameters. However, processes that control wet ... -
Characteristics and genesis of phillipsite grains in a sediment core from the Central Indian Ocean Basin
(2018)Present study is the phillipsite grains present in a siliceous sediment core (water depth 5100 m) recovered near a seamount from the Central Indian Ocean Basin (CIOB). Phillipsite occurs as single grains, cruciform crystals ... -
Integrated assessment of heavy metal contamination in water, sediments and marine organisms from Southeast coast of India
(2018)The present investigation examined the bioaccumulation of toxic metals (Cu, Zn, Cd, Hg and Pb) in water, sediment and biota along the coastal regions of Parangipettai and Nagapattinam. The concentrations of heavy metals ...
