Physiological responses of coastal phytoplankton (Visakhapatnam, SW Bay of Bengal, India) to experimental copper addition
(Elsevier, 2017)Trace amount of copper (Cu) is essential for many physiological processes; however, it can be potentially toxic at elevated levels. The impact of variable Cu concentrations on a coastal phytoplankton community was investigated ... -
Does Glacial-Interglacial Transition Affect Sediment Accumulation in Monsoon-Dominated Regions?
(Wiley, 2017)The spatio?temporal changes in sedimentation rate along the continental margin of the monsoon?dominated eastern Arabian Sea during the last 24 kyr have been estimated from a compilation of 58 radiocarbon dated cores, in ... -
Decolorization of Congo red mediated by marine Alcaligenes species isolated from Indian West coast sediments
(Springer, 2017)Alcaligenes species capable of degrading highly recalcitrant, carcinogenic, water-soluble dye-Congo red-were isolated from Indian West coastal sediments. Individual strains showed decolorization rates ranging from 76.49 ... -
Morphology and chemical composition of ash layer of about 8 Ma old from ODP-758 site, Bay of Bengal
(CSIR, India, 2017)Glass shards from an ash layer of about 8 Ma old extracted from a core drilled at an ODP-758 site in the Bay of Bengal (BOB) were studied for morphology and chemical composition in order to trace their possible source. ... -
Bacillus lacus sp. nov., isolated from a water sample of a salt lake in India
(Microbiology Society, 2018)A strictly aerobic, alkaliphilic, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK74-T, was isolated from a water sample collected from Sambhar salt lake, Rajasthan, India. Colonies were circular, ... -
Seasonal radiogenic isotopic variability of the African dust outflow to the tropical Atlantic Ocean and across to the Caribbean
(Elsevier, 2018)In order to assess the impact of mineral dust on climate and biogeochemistry, it is paramount to identify the sources of dust emission. In this regard, radiogenic isotopes have recently been used successfully for tracing ... -
Can the Drought/Flood Monsoon Conditions over the Indian subcontinent be forecasted using Artificial Neural Networks?
(CSIR, India, 2017)The Indian summer monsoon rainfall during the months June, July, August and September (JJAS) has been classified into seven climatic zones, according to standard precipitation index. Prediction of rainfall within the six ... -
Robust Projected Weakening of Winter Monsoon Winds Over the Arabian Sea Under Climate Change
(Wiley, 2017)The response of the Indian winter monsoon to climate change has received considerably less attention than that of the summer monsoon. We show here that all Coupled Model Intercomparison Project Phase 5 (CMIP5) models display ... -
Winter-time variability of the eastern Arabian Sea: A comparison between 2003 and 2013
(Wiley, 2017)The eastern Arabian Sea (EAS) is a region of complex interplay between several spatially and temporally varying oceanographic processes. Using two sets of in situ data collected from the same stations, separated by a decade, ... -
Captive breeding and rearing of the yellow seahorse, Hippocampus kuda (Bleeker, 1852) in support of the marine ornamental fish industry and conservation
(CSIR, India, 2017)H. kuda attained a maximum size of 138 mm (Ht) (mean 124.04�11.3 mm) and maximum weight of 7621 mg (mean 6904�1115.35 mg) during the culture period of six months. Overall, a survival rate of 76.28% was recorded during a ... -
Temporal effect on the abundance and diversity of intertidal rocky shore macroalgae
(Current Science Association, IAS, 2017)A study of the temporal effect on the abundance and diversity of intertidal rocky shore macroalgae re-vealed that there are ~70 species in the intertidal rocky shore of Anjuna (60 species) and Vagator (52 species) in Goa, ... -
Bacillus mangrovi sp. nov., isolated from a sediment sample from a mangrove forest
(Microbiology Society, 2017)A facultatively anaerobic, endospore forming, alkali-tolerant, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK61T, was isolated from a sediment sample collected from Coringa mangrove forest, India. ... -
Effect of pea crab Pinnotheres vicajii (Chhapgar, 1957) on immunocompetence of bivalve Paphia malabarica (Chemnitz, 1782)
(Elsevier, 2017)The endosymbiont-host relationship between a pea crab and its bivalve host has been studied previously using bivalve�s multi-physiological parameters. The present study is first of its kind that uses hemocyte�s immune ... -
Exposure of Eichhornia crassipes (Mart.) Solms to salt water and its implications
(Current Science Association, IAS, 2017)In this article, we discuss the effect of salinity on the viability and decomposition of Eichhornia crassipes plant under normal photoperiod, dark condition and physiological response. Highest concentration of total organic ... -
Seafloor geomorphology and processes on the Western continental margin of India based on multibeam acoustic backscatter data analysis
(Taylor & Francis, 2018)An assessment of the multibeam sonar data of the central Western Continental Margins of India has been carried out to evaluate the seafloor geomorphology and processes by examining the geomorphological attributes e.g., ... -
Textural characteristics and morphosedimentary environment of foreshore zone along Ganpatipule, Maharashtra, India
