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 ... -
A new species of Kirkegaardia (Annelida: Polychaeta, Cirratulidae) from the southeast coast of India
(Current Science Association, IAS, 2017)A new polychaete species, Kirkegaardia serracroochaeta sp. nov. belonging to family Cirratulidae collected from the Chennai port, southeast coast of India is described here. This species possesses distinctly serrated ... -
Benthic foraminiferal response to changes in mining pattern: a case study from the Zuari estuary, Goa, India
(Springer, 2017)Being sensitive to environmental changes, foraminifera have been extensively used to monitor pollution level in the marine environment, including the effect of mining in coastal areas. In the Goa state of India, the rejects ... -
River discharge as a major driving force on spatial and temporal variations in zooplankton biomass and community structure in the Godavari estuary India
(Springer, 2017)Variability in horizontal zooplankton biomass distribution was investigated over 13 months in the Godavari estuary, along with physical (river discharge, temperature, salinity), chemical (nutrients, particulate organic ... -
Abundance and Ecology of Endemic Asterorotalia trispinosa from the Western Bay of Bengal: Implications for its Application as a Paleomonsoon Proxy
(Wiley, 2017)A total of 97 surface sediment samples were collected from the continental shelf and slope of the western Bay of Bengal to assess the potential application of Asterorotalia trispinosa as a paleomonsoon proxy. The relative ... -
Antagonistic interactions of sponge-associated Actinobacteria against heterotrophic bacteria from sponge and ambient water
(Current Science Association, IAS, 2017)In the present study, 11 sponge-associated Actinobac-teria showed 316 inhibitory interactions against 75 heterotrophic bacteria as each Actinobacteria inhibit-ed the growth of >1 bacterial isolates from the sponge and ... -
Evaluation of the impact of bioaccumulation of PAH from the marine environment on DNA integrity and oxidative stress in marine rock oyster (Saccostrea cucullata) along the Arabian sea coast
(Springer, 2017)Marine pollution due to oil spills is of great concern globally for their impact on the health of marine ecosystems. We assessed the genotoxic effects and oxidative stress due to genotoxic pollutants accumulated from the ... -
Processes controlling the accelerated warming of the Arabian Sea
(Wiley, 2018)The Arabian Sea (AS) has undergone a regime shift after 1995, manifesting the disruption of its natural decadal cycle over-riding a secular rise in its sea surface temperature (SST). Using a suite of in situ and remote ... -
Variation of Bacterial Metabolic Rates and Organic Matter in the Monsoon-Affected Tropical Estuary (Godavari, India)
(Taylor & Francis, 2017)Bacteria play a central role in the oxidation of organic matter. In tropical estuaries, bacterial metabolic rates and carbon modification are regulated by physicochemical changes influenced by the annual monsoon-mediated ... -
70 kyr record of denitrification and oxygenation changes in the eastern Arabian Sea
(Geochemical Society of Japan, 2017)A 70 kyr record of ?15N from the eastern Arabian Sea, Core AAS9/21 was investigated. High ?15N values during interglacials and low ?15N values during glacials are documented, which mimics the global ?15N records in the ... -
