Unlocking the potential of fluorescent microbes: Exploring their ecological and industrial applications
(Elsevier, 2025)Microbial world is invisible but offers potential and rare biomolecules with an array of hues, which pose multifaceted benefits to environment and humans. Among millions of known microbes from earth, very few microbial ... -
Driving aspects of microplastic uptake: Influence in the Bentho-Pelagic ecosystem and its associated ecological risks along the coast of Goa, India
(Elsevier, 2025)Microplastics (MPs) interference in bentho-pelagic system plays a crucial role in understanding its impact on marine health and ensuring seafood safety. This study was an initial attempt to understand the realistic perspective ... -
A machine learning-based detection, classification, and quantification of marine litter along the central east coast of India
(Frontiers, 2025)Globally, the growth of plastic production has increased exponentially from 1.5 million metric tons (Mt) in 1950 to 400.3 Mt in 2022, resulting in a substantial increase of marine litter along the coastal region. Presently, ... -
Estimation of ocean mixed-layer depth using machine learning techniques
(Springer, 2025)One of the most significant variables in the ocean is the mixed layer depth (MLD). It acts as an interface between the ocean and the atmosphere influencing the climate as well as the marine ecosystem. Argo floats are most ... -
Regional Variations in Nitrous Oxide in the Indian Groundwater: Influence of Agricultural Practices, Irrigation, and Rainfall Patterns
(ACS Publications, 2025)Intensified agricultural practices, particularly the increased use of nitrogen fertilizers, are fueling the rise of nitrous oxide (N2O) in groundwater. This gas is produced through the nitrification/denitrification of ... -
In a sea of crumbling icebergs
(Cambridge University Press, 2025)In January 2009, on its way from Cape Town to South America (at around 49.5?S and 25?W), the German research vessel Polarstern entered a region with a dense cover of icebergs and broken-off chunks of ice up to a few meters ... -
Siliceous microfossils in the surface sediments of the eastern Arabian Sea
(Springer, 2025)The global oceanic silica cycle is regulated by siliceous plankton such as diatoms, radiolarians, and silicoflagellates. Among these, diatoms play a major role in oceanic CO2 sequestration as they are abundant in most ... -
Drivers of Future Indian Ocean Warming and Its Spatial Pattern in CMIP Models
(Wiley, 2025)Coupled Model Intercomparison Project phases 5 and 6 (CMIP5/6) projections display substantial inter-model diversity in the future tropical Indian Ocean warming magnitude and spatial pattern. Here, we investigate the ... -
Role of synthetic fertilizers on stable isotope ratios of particulate organic matter in the Godavari River
(Springer, 2025)In this study, we examined the major sources of particulate organic matter (POM) in the Godavari River during high flow and low flow periods, to understand the impact of excess nitrogen (N)-fertilizers used in agricultural ... -
Textural evolution of S-type micrometeorites
(Springer, 2025)Cosmic dust, the dominant extraterrestrial material entering Earth's atmosphere, undergoes textural transformation during entry. This study investigates the dependence of texture on entry conditions and classifies textures ... -
Geochemical constraints on the origin of ophiolitic chert from Naga HillsOphiolite, Northeast India
(Indian Geophysical Union, 2025)The uppermost part of the Naga Hills ophiolite (NHO) sequence representing vestiges of the Neo-Tethyan ocean in the Indo-Myanmar ranges, consists of Late Jurassic to Late Cretaceous cherts that carapace the ophiolitic ... -
Experimental heating of CI chondrite: Empirical constraints on the evolution of micrometeorite O-isotopes during atmospheric entry
(Elsevier, 2025)Extraterrestrial dust exhibits a wide range of textural, chemical and oxygen isotopic compositions due to the heterogeneity of their precursors and modification during atmospheric entry. Experimental heating provides an ... -
Antimicrobial Potential of Marine Sponge-Associated Bacillus velezensis and Stutzerimonas stutzeri from the Indian Coast: A Genome Mining and Metabolite Profiling Approach
(Springer, 2025)Antimicrobial resistance (AMR) is one of the leading health crises worldwide that demands new antimicrobials to enter the clinical pipeline. Marine sponges are a rich source of promising bioactive compounds. Due to their ... -
Potent targeted larvicidal activities of marine-derived Bacillus sp. bacterial extracts on mosquito vectors
(Springer Nature, 2025)Mosquito vector-borne diseases are one of the leading causes of mortality and morbidity across the globe. Current vector control strategies mainly rely on chemical insecticides, but their incessant usage has resulted in ... -
Geochemistry and mineralogy of modern fjord sediments, west Spitsbergen, Svalbard: implications for provenance and weathering
(Springer, 2025)Arctic fjords are ideal sites for studying the recent sedimentary process that affects high-latitude coastal ecosystems. High latitude Raudfjord, Magdalenefjord, and St. Jonsfjord from the west Spitsbergen, Svalbard have ... -
Distribution, sources and bioaccumulation of polycyclic aromatic hydrocarbons (PAHs) in oysters of Sal estuary Goa, India
(Elsevier, 2025)Present study aimed to unfurl occurrence and accumulation of Polycyclic Aromatic Hydrocarbons (PAHs) in water and oysters of Sal estuary (Goa, India). The highest total PAHs concentration were observed at mid estuary (SSJ2) ... -
Vertical structure of mesoscale eddies and their impact on the modulation of tracer fields in the eastern Arabian Sea
(Springer, 2025)The present study utilises a combination of observation and ocean reanalysis data to comprehend the vertical structure of mesoscale eddies and their influence on the modulation of tracer properties (temperature, salinity, ... -
First report of a giant protist Tricranastrum trinibrachium Takahashi 1991 (syn. Myelastrum trinibrachium) from the Indian Ocean
(Oxford University Press, 2025)Rhizarians play an important role in ocean biogeochemistry and are used as paleoproxies. These organisms, specifically the giant ones, which are fragile in nature, are poorly studied and understood. A rhizarian species ... -
Phthalic acid esters as an ecological hazard to the coral reef ecosystems: A case study from the coral reef waters of the Lakshadweep Archipelago, Arabian Sea
(Elsevier, 2025)Information regarding the sources, distribution and ecological implications of organic contaminants in the coral reef ecosystems is limited. Phthalic acid esters (PAEs) are toxic contaminants due to their endocrine-disrupting ... -
