Beaches in the Plasticene : Risk assessment of anthropogenic marine litter pollution and mitigation measures in beach ecosystems of the West Coast of India
(Elsevier, 2025)Mismanaged solid waste and plastics pose a significant global environmental challenge, affecting ecosystems from coastlines to the deep-sea basin. This study provides a comprehensive assessment of anthropogenic marine ... -
Phytoplankton response to winter cooling in the recent past in the northeastern Arabian Sea: Evidence from sedimentary phytodetritus and satellite data
(Springer Nature, 2025)In the northeastern Arabian Sea, winter convective mixing induces high productivity, which could be sensitive to the ongoing surface ocean warming and related changes in monsoon winds affecting the phytoplankton community. ... -
Is a warming northern Indian Ocean generating more tropical cyclones?
(Taylor & Francis, 2025)Tropical cyclones in the northern Indian Ocean (IO) were examined in the context of basin-specific warming from 1960 to 2022. In the Arabian Sea (AS) the increase in the total number of cyclones on a decadal-time scale ... -
Exploring land surface temperature (LST) and spectral signatures of Baratang and Diglipur mud volcanoes using ASTER VNIR-SWIR-TIR bands in the Andaman and Nicobar Islands, India
(Elsevier, 2025)Mud volcanoes (MVs) are sedimentary volcanoes formed by the escape of overpressured fluids from deep, unconsolidated sediment layers. Studying these geological features is crucial for understanding the degassing processes ... -
Assessing the ecological preferences of planktic foraminifera from the south-eastern Arabian Sea
(Elsevier, 2025)The south-eastern Arabian Sea (SEAS) witnesses the confluence of the Arabian Sea and the Bay of Bengal waters along with an influence from both the summer and winter monsoon. As a result, the distinct hydrographic parameters ... -
Chemosynthetic Organic Matter Reveals a Protracted Episode of Past Methane Seepage Activities at a Newly Discovered Cold Seep Site (Mannar Basin) Off the East Coast of India
(American Geophysical Union, 2025)Here, we present organic geochemical evidence of past methane-seepage events in a sediment core retrieved from a recently discovered methane cold-seep site off Mannar Basin, east coast of India. The significant negative ... -
Response of Diatoms to the Addition of Bamboo in the Eastern Arabian Sea
(Wiley, 2025)Nutrient availability limits phytoplankton growth throughout much of the global ocean, and this has led scientists to consider fertilizing the ocean with phytoplankton growth-limiting nutrients. We studied the response of ... -
Metal bioaccumulation in edible fauna and phytoremediation by mangroves in the Mandovi Estuary, India
(Springer, 2025)The study investigated bioaccumulation of metals in edible bivalves and crustaceans in the Mandovi Estuary, assessing the potential toxicity to biota and human consumers. Additionally, it examined the phytoremediation ... -
Magnetic structure of the uppermost mantle of the Eastern Continental Margin of India and Bay of Bengal inferred from Curie depths estimated by analysing shipborne magnetic data using Bayesian inversion
(Oxford University Press, 2025)The Eastern Continental Margin of India (ECMI) is a classic passive margin formed during the Mesozoic breakup of the supercontinent Gondwanaland. Since its formation, the margin has undergone complex post-rift thermal ... -
Multi-sensor analysis of low-level cloudiness and its controlling factors over the Indian Ocean
(Elsevier, 2025)In this study, we analysed nearly two decades (2001–2021) of satellite borne multi-sensor low-level cloud fraction (LCF) datasets and reanalysis meteorological parameters over the Indian Ocean, to examine spatial–temporal ... -
Xylanase of Bacillus sp. NIORKP76 grown under solid state fermentation: production, purification, characterization and its saccharification potential
(Taylor and Francis Group, 2025)Microbial xylanases are xylan hydrolyzing enzymes which has congregated attention due to their immense potential in many industries. The current study is focused on xylanase from bacterial isolate identified as Bacillus ... -
Petrography of scoriaceous and unmelted micrometeorites from the Maitri Station, Antarctica collection
(Elsevier, 2025)We analysed ten unmelted fine-grained micrometeorites (FgMMs) and ten coarse-grained micrometeorites (CgMMs), along with eight fine-grained scoriaceous micrometeorites (Fg/ScMMs) and sixteen scoriaceous micrometeorites ... -
New Marine Actinobacteria Strain, Micromonospora sp. SH-82: Characterization, Specialized Metabolites and Biological Activities
(MDPI, 2025)The study of various microorganisms isolated from an Indian Ocean sponge, Scopalina hapalia ML-263, led to the selection of a promising Actinobacteria strain, Micromonospora sp. SH-82. Genomic analysis identified this ... -
Upper Ocean Carbon Export Flux Estimation in the East Indian Ocean Using 234Th
(American Geophysical Union, 2025)The strength of the Biological Carbon Pump (BCP) to sequester atmospheric CO2 in the East Indian Ocean is unclear due to lack of studies. Here, we estimated Particulate Organic Carbon (POC) export flux by using 234Th as a ... -
Transcriptomic response of Cinachyrella cf. cavernosa spongesto spatial competition
(Wiley, 2025)Spatial competition in the intertidal zones drives the community structure in marine benthic habitats. Organisms inhabiting these areas not only need to withstand fluctuations in temperature, water level, pH, and salinity ... -
Temporal Variations in Wave Systems in a Multimodal Sea State in the Coastal Waters of the Eastern Arabian Sea
(MDPI, 2025)Multimodal waves can significantly impact ocean–atmosphere interactions and affect coastal ecosystems. Due to the presence of waves created in different geographical areas, many wave systems coexist in coastal seas. Based ... -
First record of Elysia cf. leucolegnote Jensen, 1990 in the Indian mainland mangrove habitats of Karnataka
(Cambridge University Press, 2025)The current study records a new distributional range for Elysia cf. leucolegnote Jensen, 1990, which was previously reported only from the Andaman and Nicobar Islands in India. The collection was carried out in the mangroves ... -
A strong influence of the precession and northern high latitudinal climate on the monsoon seasonality and productivity in the Andaman Sea
(Elsevier, 2025)The Indian Monsoon (IM) is a vital component of the global climate system, driving seasonal changes in precipitation, productivity, and circulation in the Indian Ocean. However, despite its significance in affecting the ... -
Evaluating the ecological risks of marine litter and derelict fishing nets on Olive Ridley hatchlings: Insights from a globally renowned rookery along the east coast of India
(Elsevier, 2025)Anthropogenic marine litter have become a pressing environmental challenge, posing serious risks to marine organisms and the ecosystem. This study assessed litter composition, density, and ecological impact across four key ... -
A large glacial-interglacial shift in carbon burial in the northeast Indian Ocean during the Late Quaternary
(Elsevier, 2025)Carbon is a common element on Earth, found in various molecular forms. However, the excessive release of carbon dioxide (CO2) into the atmosphere from burning fossil fuels is a major concern due to its greenhouse potential. ...
