Oil pollution in the Eastern Arabian Sea from invisible sources: A multi-technique approach
(2019)The Eastern Arabian Sea (EAS) is affected by oil pollution, as often evidenced by the presence of tarballs along the West Coast of India (WCI). Tarball samples collected during May 2017 along the Goa coast were subject to ... -
Experimental and Kinetic studies on the combined influence of ultrasonication and rare earths on removal of azo dyes
(2019)The aim of the present study is to decolorize azo dyes containing (-N=N-) bonds such as Reactive Black 5 (RB 5), Basic Blue 3 (BB-3) and Disperse Blue 373 (DB 373) in the presence of ultrasound (US) and rare earth (RE), ... -
Deep-Sea Mining and the Environment: An Introduction
(2019)Seafloor minerals, many of which occur in the deep ocean in international waters, have attracted significant attention due to the discovery of deposits with high metal grades and large volumes, in addition to the growth ... -
Seismic evidence of free gas migration through the gas hydrate stability zone (GHSZ) and active methane seep in Krishna-Godavari offshore basin
(2019)Seismic amplitude versus offset (AVO) analysis was performed on the multichannel seismic data in the vicinity of Site NGHP-01-10, where thick fracture-filled gas hydrate is reported, to understand the fluid migration in ... -
A global Plankton diversity monitoring program
(2019)Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR ... -
Origin and distribution of shallow gas-charged sediment on the inner continental shelf of central west coast of India
(2019)High-resolution shallow seismic investigations on inner continental shelf of Goa have been carried out to map gas-charged sediment zones and investigate origin of trapped gas. Analyses of data reveal that the gas is trapped ... -
Conidial germination of marine-derived fungi under simulated deep-sea conditions in the presence of inducers
(2019)The abilities of conidia of four deep-sea fungi, Aspergillus flavus NIOCC20, A. sydowii CH2, A. terreus A4636 and Penicillium sp. A4623 and one terrestrial fungus, A. terreus MTCC479 to germinate under simulated deep-sea ... -
Crustal architecture and rift tectonics across the Visakhapatnam Bay basin, central-east Indian margin: Insights from multichannel seismic and potential field data
(2019)The Visakhapatnam Bay (VB) basin is a passive margin rift basin located at the non-basinal segment of the Eastern Continental Margin of India (ECMI) and formed during the rift-drift events associated with the breakup of ... -
Dinoflagellate planktonic-motile-stage and benthic-cyst assemblages from a monsoon-influenced tropical harbour: Elucidating the role of environmental conditions
(2019)Dinoflagellates are referred among potential bioinvaders and environmental proxies. Information from tropical regions on the coupling of cyst and motile stages of dinoflagellates characterized by high suspended-load, and ... -
Large-Scale Fresh and Salt Water Exchanges in the Indian Ocean
(2019)Upper-ocean dynamics in the Northern Indian Ocean (NIO) depend on changes in the magnitude and location of the high salinity waters of the Arabian Sea and low salinity waters of the Bay of Bengal. The large sea surface ... -
Seasonal spreading and transport of buoyant plumes in the shelf off Kochi, South west coast of India- A modeling approach
(2019)We investigated the seasonal spreading and transport of buoyant plume in the shelf off Kochi using Finite Volume Community Ocean Model (FVCOM). The modelled river plume typically consisted of an offshore bulge and a coastal ... -
Prokaryotic Diversity in Oxygen Depleted Waters of the Bay of Bengal Inferred Using Culture-Dependent and -Independent Methods
(2019)There are regions in the world oceans where oxygen saturation is at its lowest, evident at depths between shelf to upper bathyal zone. These regions are known as Oxygen Minimum Zones (OMZs), which reportedly support ... -
New record of Loricophyra stresemanni (Ciliophora: Suctorea) as epibiont on nematodes from the Indian Ocean and notes on the genus Loricophrya
(2019)The article is dedicated to the re-discovery of suctorian ciliate Loricophrya stresemanni found on nematodes from Miramar bay (Arabian Sea), Goa, west coast of India. The morphological characterizations of collected ciliate ... -
Carbon Dioxide Sequestering Ability of Bacterial Carbonic Anhydrase in a Mangrove Soil Microcosm and Its Bio-mineralization Properties
(2019)In this study, we attempt to prospect potential bacterial isolates from mangrove sediments of Mangalavanam, Kerala, India, with positive carbonic anhydrase (CA) activity to sequester carbon dioxide by calcium precipitation ... -
Spatial distribution of gas hydrate deposits in Krishna-Godavari offshore basin, Bay of Bengal
(2019)To delineate the occurrences of gas hydrates and free gas in the Krishna-Godavari (KG) basin, Bay of Bengal, we used 3D seismic data to construct a velocity model of high spatial density. We used an automated version of ... -
Aragonite pteropod abundance and preservation records from the Maldives, equatorial Indian Ocean: Inferences on past oceanic carbonate saturation and dissolution events
(2019)During the International Ocean Discovery Program (IODP) Expedition 359, a long continuous carbonate-rich sequence was recovered from the Inner Sea of Maldives. We investigated pteropod proxies (absolute abundance of pteropods ... -
A sustained ocean observing system in the indian ocean for climate related scientific knowledge and societal needs
(2019)The Indian Ocean is warming faster than any of the global oceans and its climate is uniquely driven by the presence of a landmass at low latitudes, which causes monsoonal winds and reversing currents. The food, water, and ... -
Crustal architecture and moho topography beneath the Eastern Indian and bangladesh margins - New insights on rift evolution and the continent-ocean boundary
(2019)The thick sedimentary cover (?18 km) along the Eastern Continental Margin of India (ECMI) and over the Bay of Bengal has hindered understanding of the mechanisms of rifting that operated on the eastern Indian and Bangladesh ... -
Large-scale mass wasting on the Miocene continental margin of western India
(2019)A giant mass-transport complex was recently discovered in the eastern Arabian Sea, exceeding in volume all but one other known complex on passive margins worldwide. The complex, named the Nataraja Slide, was drilled by ... -
Natural decadal sea-level variability in the Indian Ocean: lessons from CMIP models
