First report of toxic Prorocentrum rhathymum (Dinophyceae) and its pigment composition from coastal waters of the eastern Arabian Sea
(2018)Prorocentrum rhathymum,a toxic dinoflagellate, was isolated for the first time from coastal waters of the eastern Arabian Sea. Batch cultures were grown and cell pellets were extracted in methanol for analysis of algal ... -
Thioredoxin fused CHH1 protein as antigen for polyclonal antisera: Application to regulate glycemia in Penaeus monodon
(2018)Crustacean hyperglycemic hormone (CHH) family neuropeptides have been in research limelight for the past two decades due to their importance in the regulation of glycemia, moulting and gonad development in crustaceans. ... -
Isolation and structure elucidation of halymeniaol, a new antimalarial sterol derivative from the red alga Halymenia floresii
(2018)A new mono-hydroxy acetylated sterol derivative: 12?-hydroxy-3?, 15?, 16?-triacetoxy-cholest-5-en-7-one (halymeniaol) (1), and cholesterol (2) were isolated from the marine red alga Halymenia floresii. The structure of the ... -
Preface: Microbial Community Response to Ocean Deoxygenation
(2018)Preface by guest editors to the special issue on Ecosystem Response to Ocean Deoxygenation -
Mud Banks along the southwest coast of India are not too muddy for plankton
(2018)Considering Alappuzha Mud Bank in the southern Kerala coast as a typical case of biologically productive Mud Banks that form along the southwest coast of India during the Southwest Monsoon (June - September), the present ... -
Influence of Dam-Controlled River Discharge and Tides on Salinity Intrusion in the Godavari Estuary, East Coast of India
(2018)The Godavari is an important tropical monsoonal river located along the east coast of India. The Gautami-Godavari is one of the two major estuarine branches of the Godavari River bifurcated by a low dam at Dowlaiswaram. ... -
Glacial-interglacial changes and Holocene variations in Arabian Sea denitrification
(2018)At present, the Arabian Sea has a permanent oxygen minimum zone (OMZ) at water depths between about 100 and 1200 m. Active denitrification in the upper part of the OMZ is recorded by enhanced δ15N values in the sediments. ... -
Spatio-temporal variability of upwelling along the southwest coast of India based on satellite observations
(2018)Upwelling phenomenon along the eastern boundaries of global ocean has received greater attention in the recent times due to its environmental and economic significance in the global warming and the scenario of changing ... -
Planktonic food web structure at SSTF and PF in the Indian sector of the Southern Ocean during austral summer 2011
(2018)This study aims to describe the planktonic food web structure with respect to phytoplankton biomass (chlorophyll a) and prevailing environmental conditions at the South Subtropical Front (SSTF) and the Polar Front (PF) in ... -
DNA damage in marine rock oyster (Saccostrea Cucullata) exposed to environmentally available PAHs and heavy metals along the Arabian Sea coast
(Elsevier, 2018)Molecular biomarkers are used world wide for quick assessment of the immediate effect of environmental pollution on marine ecosystems. Recently, we evaluated oxidative stress responses of marine rock oyster, Saccostrea ... -
Paleomagnetic record for the past 80 ka from the Mahanadi basin, Bay of Bengal
(Pergamon, 2018)High resolution paleomagnetic investigations were performed on a 50.08 m long sediment core (MD161/20) from Mahanadi basin, Bay of Bengal. Core yielded reliable paleomagnetic results for top 20 m below seafloor (mbsf) which ... -
Upper air thermal inversion and their impact on the summer monsoon rainfall over Goa - A case study
(Pergamon, 2018)Profiles of periodic GPS Radiosonde ascends collected from a station at the west coast of India (Goa) during summer monsoon months (June to September) of 2009 and 2013 have been used to analyze the thermal inversion ... -
Comparative efficacy of benthic biotic indices in assessing the Ecological Quality Status (EcoQS) of the stressed Ulhas estuary, India
(Elsevier, 2017)Ecostatus of Ulhas estuary, one of the most polluted estuaries along the industrialized and urbanized northwest coast of India, was evaluated by six widely accepted benthic indices viz. H?(log2), AMBI, M-AMBI, BENTIX, BOPA ... -
Polychaete assemblage driven by substrate composition along the coastal waters of the South-eastern Arabian Sea
(Elsevier, 2017)The spatial variation in polychaete community structure and sediment composition was studied along the coastal waters of the South-eastern Arabian Sea. Sampling was conducted during the pre-monsoon season (2011-2014) in ... -
Last glacial-interglacial productivity and associated changes in the eastern Arabian Sea
(Elsevier, 2017)We reconstruct paleo-productivity and bottom water oxygenation changes during the past 32ka, from the southeastern Arabian Sea, using absolute abundance of planktic foraminifera, relative abundance of Globigerina bulloides, ... -
An insight into mercury reduction process by humic substances in aqueous medium under dark condition
(Springer, 2017)Mercury (Hg) reduction by humic substances (HS) in the aquatic medium under the dark condition is a poorly understood but important process in Hg biogeochemical cycling. In this study, an effort was made to provide a better ... -
Indian summer monsoon forcing on the deglacial polar cold reversals
(Springer, 2017)The deglacial transition from the last glacial maximum at similar to 20 kiloyears before present (ka) to the Holocene (11.7 ka to Present) was interrupted by millennial-scale cold reversals, viz., Antarctic Cold Reversal ... -
Bioremediation of tannery wastewater by a salt-tolerant strain of Chlorella vulgaris
(Springer, 2017)Phycoremediation is the use of algae for removal or reduction of inorganic nutrients and xenobiotics from wastewaters. It is a reliable process for biotransformation and detoxification of a variety of pollutants. This study ... -
