Probing the nature of extraterrestrial dust reaching the Earth�s surface collected from the Maitri station, Antarctica
(University of Arkansa, 2020)Micrometeorites (MMs) are extraterrestrial dust particles, in the size range of tens of �m to mm, recovered from the Earth�s surface primarily from deep-sea sediments, Antarctica, and also from space. The present collection ... -
Anomalous phase association of REE in ferromanganese crusts from Indian mid-oceanic ridges: Evidence for large scale dispersion of hydrothermal iron
(Elsevier B.V., 2020)Ferromanganese crusts collected at selected locations along the ~7000 km long stretch of Carlsberg, Central Indian and Southwest Indian ridges are studied for bulk geochemical composition and distribution of rare earths ... -
Recent salinity intrusion in the Bengal delta: Observations and possible causes
(Elsevier Ltd, 2020)Salinization stands among the most prominent environmental hazards of the largest delta on Earth, the Bengal delta. It has significant impacts on the local societies and the economy. Using an unprecedented collection of ... -
High-resolution Operational Ocean Forecast and reanalysis System for the Indian Ocean
(American Meteorological Society, 2020)A good understanding of the general circulation features of the oceans, particularly of the coastal waters, and ability to predict the key oceanographic parameters with good accuracy and sufficient lead time are necessary ... -
Observed variability of the East India Coastal Current on the continental shelf during 2010-2018
(Springer, 2020)We describe the variability of the East India Coastal Current (EICC) during 2010-2018 on the outer continental shelf using data from four ADCP (acoustic Doppler current profilers) moorings deployed off Gopalpur (~ 19.5�N), ... -
Freeze-drying partially affects dead benthic foraminiferal shells in estuarine sediments
(Palaeontological Society of India, 2020)Foraminiferal proxies are often used to understand both pollution and past climatic changes. The freeze-drying is a viable alternative to commonly used method of oven-drying to process marine sediments for foraminiferal ... -
Post-breakup deformations in the Bay of Bengal: Response of crustal strata to the sediment load
(Springer, 2020)Passive continental margins are tectonically inactive, but a few of them including the East India Passive Margin (EIPM) show evidences for post-breakup deformations. This unusual process prompted us to investigate the ... -
Report of ciliate epibionts (Ciliophora) on meiobenthic invertebrates from Indian coast near Karwar, Karnataka
(Protozoological Society Affiliated with RAS, St. Petersburg, Russia, 2020)The article describes four epibiont suctorian ciliates, viz. Thecacineta cothurnioides (Collin, 1909) and Trematosoma rotunda (Allg�n, 1952) on the nematode Tricoma sp., Thecacineta calix (Schr�der, 1907) and Acineta ... -
Cryptic roles of tetrathionate in the sulfur cycle of marine sediments: microbial drivers and indicators
(Copernicus Publications, European Geosciences Union, Germany, 2020)To explore the potential role of tetrathionate in the sedimentary sulfur cycle, population ecology of microorganisms capable of metabolizing this polythionate was revealed at 15-30 cm resolution along two, ~3 m long, cores ... -
Quantifying the benefits of non-linear methods for global statistical hindcasts of tropical cyclones intensity
(American Meteorological Society, 2020)While Tropical Cyclones (TCs) track forecasts have become increasingly accurate over recent decades, intensity forecasts from both numerical models and statistical schemes have been trailing behind. Most operational ... -
Elevated turbidity and dissolved manganese in deep water column near 10�47�S Central Indian Ridge: studies on hydrothermal activities
(Springer Science and Business Media Deutschland GmbH, 2020)The deep water in the ridge segment between 10°18'S and 10°57'S of northern Central Indian Ridge was surveyed with CTD and AUV for seafloor hydrothermal activities. During the survey, 25 CTD hydrocasts were made, and ... -
Nitrogen and carbon cycling over the western continental shelf of India during seasonal anoxia: A stable isotope approach
(Elsevier B.V., 2020)The western continental shelf of India (eastern Arabian Sea) houses the world�s largest seasonally-occurring coastal low-oxygen zone. The natural abundance of nitrogen and oxygen isotopes in dissolved nitrate were measured ... -
Biogenesis of silver nanoparticles by marine bacteria Labrenzia sp. Mab 26 associated with Isochrysis galbana
(Current Science Association, IAS, 2020)The metabolic or chemical nature of algal-bacterial interactions has opened up unexpected new ways for finding novel microbes with potential for several biotechnological applications. Silver nanoparticles (AgNps) possess ... -
Geochemical characterization of modern aeolian dust over the Northeastern Arabian Sea: Implication for dust transport in the Arabian Sea
(Elsevier, 2020)The Arabian Sea, one of the most biologically productive oceanic regions, receive significant amount of nutrients through aeolian dust deposition which have potential to modulate surface water biogeochemical processes. ... -
