Copepoda community imprints the continuity of the oceanic and shelf oxygen minimum zones along the west coast of India
(Elsevier, 2024)The largest continental shelf Oxygen Minimum Zone (OMZ) in the world is formed along the Indian western shelf in the eastern Arabian Sea during the Southwest Monsoon [(SWM); June-September], which is a natural pollution ... -
Assessment of equivalent black carbon variations and its source apportionment over Varanasi, Indo-Gangetic Basin
(Elsevier, 2024)In this study, the temporal variation of Equivalent Black Carbon (eBC) and its source apportionment is studied using a yearlong (Dec. 2020-Nov. 2021) multiwavelength Aethalometer (AE-33 model) measurements over Varanasi, ... -
Distribution, source and potential biological impacts of polycyclic aromatic hydrocarbons in the core sediments of a networked aquatic system in the northwest coast of India - A special focus on Thane Creek Flamingo Sanctuary (Ramsar site)
(Elsevier, 2024)Mumbai, one of the most industrialised and inhabited cities in the world, has been confronting an exponential increase in pollution brought about by anthropogenic activities throughout its coastal belt over the years. The ... -
Factors regulating proliferation and co-occurrence of loricate ciliates in the microzooplankton community from the eastern Arabian Sea
(Springer, 2024)Ciliates are highly developed and diverse eukaryotes belonging to the microzooplankton community; they exhibit a wide distributional range and are a crucial component of the microbial food web. The current study addresses ... -
Occurrence, sources and risk assessment of polycyclic aromatic hydrocarbons in the coral reef waters of the Lakshadweep Archipelago, Arabian Sea
(Elsevier, 2024)The compound effects of anthropogenic disturbances on global and local scales threaten coral reef ecosystems of the Arabian Sea. The impacts of organic pollutants on the coral reefs and associated organisms have received ... -
A distinct and reproducible teleconnection pattern over North America during extreme El Nino events
(Nature Publishing Group, 2024)El Nino-Southern Oscillation (ENSO) teleconnections are an important predictability source for extratropical seasonal climate forecasts. Previous studies suggest that the ENSO teleconnection pattern depends on the ENSO ... -
An integrated buoy-satellite based coastal water quality nowcasting system: India�s pioneering efforts towards addressing UN ocean decade challenges
(Elsevier, 2024)The Indian coastal waters are stressed due to a multitude of factors, such as the discharge of industrial effluents, urbanization (municipal sewage), agricultural runoff, and river discharge. The coastal waters along the ... -
Discovery of late Quaternary giant magnetofossils in the Bay of Bengal
(Nature Publishing Group, 2024)Unusually large and enigmatic giant magnetofossils are well-documented in sediments deposited during and surrounding climatic events such as the Paleocene-Eocene Thermal Maximum (~56?Ma) and Middle Eocene Climatic Optimum ... -
Investigating the wave attenuation capabilities of rectangular pile head breakwater: A physical modelling approach
(Pergamon, 2024)The study provides a comprehensive examination of single row Rectangular Pile Head Breakwaters (RPHB), encompassing both non-perforated and perforated variations. In the non-perforated RPHB category, the investigation ... -
Environmental monitoring of the Kavaratti lagoon, Lakshadweep Islands, Arabian Sea using larger foraminiferal distribution
(SAGE Publications, New Delhi, India, 2023)Coral reef environments are known for the proliferation of algal symbiont-bearing foraminifera, which are sensitive indicators of water-quality conditions that support reef development. Keeping this in mind, 18 sediment ... -
Intrinsic versus wind-forced great whirl non-seasonal variability
(John Wiley & Sons, Ltd, 2024)The Great Whirl (GW) is a quasi-permanent anticyclonic eddy that appears every summer monsoon offshore of the Somalia upwelling. The annual cycle of the GW is well described, but deviations from its mean seasonal cycle ... -
Unraveling the land-based discharge of microplastics from sewers to oceans - A comprehensive study and risk assessment in wastewaters of Goa, India
(Elsevier, 2024)Owing to their pervasive dispersion in the environment and their potential ramifications on both marine life and human health, microplastics (MPs) are of increasing concern. However, there is still a lack of research on ... -
Impact of local and remote winds on the surface waves in the coastal waters of eastern Arabian Sea
(Elsevier, 2024)This research aims to provide analysis of wave propagation and the interaction between local and remote winds on surface waves in the coastal waters of the eastern Arabian Sea. The analysis is based on measurements from a ... -
Influence of environmental settings in geographically distinct ports on the protein profiles of cultivable bacteria using MALDI-TOF mass spectrometry
(John Wiley & Sons, Ltd, 2024)The protein profiles of bacteria are useful markers in their identification. In this study, we examined the influence of environmental settings on the protein profiles of culturable bacteria using matrix-assisted laser ... -
Spatial distribution of pteropods from North Andaman Sea: Insights into aragonite supply and deposition in low saline, delta shelf regimes
(SAGE Publications, New Delhi, India, 2023)Pteropods are important components of the marine zooplankton. Not only are they crucial parts of the pelagic ecosystem but are also key contributors to the global carbon budget. Their shells sink to the ocean floor ... -
