Fatty acid and sterol biomarkers as indicators of symbiont activity in chemosynthetic organisms from a methane seep ecosystem (Krishna�Godavari basin, Bay of Bengal)
(Springer, 2025)In the present study, an attempt was made to characterize the bacterial symbionts present in the organisms, their carbon sources and assess tissue-specific isotope variability within the organisms in Bathymodiolus, ... -
Island mass effect alters the biogeochemistry of the coastal waters around Grande Island in the Eastern Arabian Sea
(Springer, 2025)Coastal oceans are highly dynamic regions of ecological and economic importance that are vulnerable to different stressors. We investigated the spatio-temporal variations in the biogeochemistry of the coastal waters ... -
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 ... -
Deep-sea life associated with sediments and polymetallic nodules from the Central Indian Ocean Basin: Insights from 18S metabarcoding
(Elsevier, 2025)The eukaryotic diversity of ocean sediments and polymetallic nodules (PMN) from the Central Indian Ocean Basin (CIOB) is scarcely characterized and molecular studies are lacking, comprising a key research gap. This study ... -
Metagenomic reconstruction of microbial genomes and biogeochemical pathways: insights into carbon and nitrogen flux dynamics in the eastern Arabian Sea
(Elsevier, 2025)The eastern Arabian Sea (EAS) experiences seasonal nutrient availability and productivity shifts driven by the Indian monsoon, influencing microbial contributions to biogeochemical cycles. This study explores carbon, ... -
Cost-effective copper nanoparticles for enhanced photocatalytic degradation of triarylmethane (TAM) dyes in direct seawater
(Elsevier, 2025)In recent years, the environmental impact of triarylmethane dyes (TAMs) has become an ever-increasing concern, as their widespread use in various industries has led to their persistent presence in wastewater, causing serious ... -
Thermal desiccation and relative gene expression of HSP90 in an acorn barnacle, Amphibalanus amphitrite
(Elsevier, 2025)Sessile and sedentary invertebrates respond to various magnitudes of thermally desiccated stress during tidal emersion, and regulation of body temperature plays a crucial role in survival during an intraday aerial exposure. ... -
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 ... -
Impact assessment of oil spills on the Red Sea waters using remote sensing and numerical modeling
(Elsevier, 2025)Understanding the impact of oil spills on marine environments requires a comprehensive evaluation of bio-physical and optical properties. This study focuses on assessing and monitoring optical properties of Red Sea waters ... -
Spatial variation of micrometeorite abundance in global ocean
(Elsevier, 2025)Annually, Earth accumulates ?40,000 tons of cosmic dust, with ?4000�6000 tons reaching the surface as micrometeorites (MMs). This study analyzes ?3 tons of wet sediments and ?5000�MMs from the Central Indian Ocean Basin, ... -
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 ... -
Factors influencing the outbreak of Phaeocystis (Prymnesiophyceae) bloom in the coastal waters off Digha
(Elsevier, 2025)Phaeocystis blooms are considered harmful algal blooms due to its negative impacts on the ecosystem. This study investigates the responsible factors for outbreak of Phaeocystis bloom in the coastal waters off Digha ... -
Tidal control of heavy metal loading in the nearshore of the northwestern Indian coast
(Elsevier, 2025)Heavy metals accumulate in the marine food chain and their excessive amounts are hazardous to aquatic and human lives. The current study presents the role of ecosystem variables especially tides in deciding the presence ... -
Persistent elevated levels of dissolved lead in the Indian Ocean post-leaded gasoline ban: The impact of anthropogenic activities, sediment desorption, and dust storms
(Elsevier, 2025)This study examines the distribution of dissolved lead (dPb) in the Indian Ocean, based on seawater samples collected during winter monsoon GI10 (2020) and spring inter-monsoon GI09 (2021) cruises. A total of 510 samples ... -
