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 ...
Quantification of long-range transported aeolian dust towards the Indian peninsular region using satellite and ground-based data - A case study during a dust storm over the Arabian Sea
(Elsevier Ltd, 2020)
The Arabian Sea is an enclosed basin surrounded by land and is prone to receive large amount of aeolian dust from the continent. This can significantly impact surface water biogeochemical processes. In this study, an attempt ...
Response of microplankton size structure to summer stratification, freshwater influx and coastal upwelling in the Southeastern Arabian Sea
(2020)
A year-round FlowCAM-based study of micro-plankton (20-200 μm) size structure was conducted in several locations along a cross-shore transect off Kochi in the near-shore waters of the southeastern Arabian Sea (SEAS; along ...
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 ...
Influence of dual sulfate reduction pathways on pore-fluid chemistry and occurrences of methane hydrate in sediment cores (IODP-353) off Mahanadi basin, Bay of Bengal
(Geochemical Society of Japan, 2020)
Pore fluid chemistry of sediment cores from two coring sites collected from Mahanadi basin (Bay of Bengal) during IODP-353 was studied to understand the intra-basinal variation in microbially mediated sediment biogeochemistry ...
Aliasing of the Indian Ocean externally-forced warming spatial pattern by internal climate variability
(2020)
Coupled Model Intercomparison Project (CMIP5) models project an inhomogeneous anthropogenic surface warming of the Indian Ocean by the end of the 21st century, with strongest warming in the Arabian Sea and Western equatorial ...
Isolation and characterization of a moderately halophilic Marinobacter phage-host system from the Arabian Sea
(Springer, 2020)
Marinobacter is an ecologically important genus of Gammaproteobacteria found in diverse marine habitats, many species of which are capable of degrading hydrocarbons. In this study, we isolated a Marinobacter phage-host ...
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 ...
Hydrological regulation of Vibrio dynamics in a tropical monsoonal estuary: a classification and regression tree approach
(Springer Science and Business Media Deutschland GmbH, 2021)
Dynamics of Vibrio populations in aquatic environments are of concern, as they encompass members pathogenic to humans as well as marine flora and fauna. Spatiotemporal distribution of its culturable abundance for a range ...
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 ...
