Taxa specific grazing-induced phytoplankton chlorophyll breakdown pathway: implication in algal bloom monitoring and mitigation programs
(Taylor and Francis Online, 2025)The roles of biotic factors (grazing/senescence) in chlorophyll a (Chl a) breakdown (CB) to non-fluorescence derivatives in a multistep pathway are frequently reported. In aquatic microalgae, the information on CB-pathway ... -
Functional Redundancy as an Indicator of Potential Ecosystem Stability: a Case Study on Macrobenthic Polychaete Communities from a Highly Urbanized Coast
(Springer Nature, 2025)In urban coastal habitats, prolonged intensified human activities significantly alter global ecological communities by losing species and their associated functions, resulting in a regional species pool where different ... -
Unraveling the bacterial composition of a coral and bioeroding sponge competing in a marginal coral environment
(Frontiers, 2025)The newly described bioeroding sponge Cliona thomasi, part of the Cliona viridis complex, is contributing to coral decline in the central eastern Arabian Sea, the West Coast of India. While its morphological and allelopathic ... -
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. ... -
Atmospheric Deposition, Shelf Sediment Supply, Riverine Input, and Redox Conditions Control Dissolved Manganese in the Indian Ocean
(Wiley Online Library, 2025)Abstract Dissolved manganese (dMn) is an essential bioactive element required for marine organisms. Redox condition determines its solubility and its solid phase removal from seawater. It displays a typical scavenging type ... -
Seismic chimneys as gas migration pathways and their role in hydrate accumulation: AVA insights from the Cauvery-mannar basin
(Elsevier, 2025)Gas hydrates have been identified in the Cauvery-Mannar Basin, a passive rift setting largely devoid of recent tectonic activity as evidenced by seismic data. This study provides novel insights into gas migration pathways ... -
Pre-requisite conditions for the intensification of pre-monsoon cyclones over the Bay of Bengal
(Springer Nature, 2025)The intensification of pre-monsoon cyclones in the northern Bay of Bengal, particularly Cyclone Yaas (2021), is increasingly attributed to the rising influx of freshwater from the Ganges and Brahmaputra rivers. Cyclone ... -
Global marine plastic pollution: Sources, distribution, implications on human health and mitigation strategies
(Elsevier, 2025)Plastic pollution has emerged as a pressing environmental crisis, with global production surging from 2 million tonnes per year in the 1950s to a staggering 460 million tonnes in 2019. A substantial portion of this plastic ... -
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 ... -
Responses of zooplankton (copepods) in the Indian mud bank-upwelling region
(Elsevier, 2025)In 2014 and 2016, the ecology and composition of zooplankton in the Alappuzha mud bank-upwelling area along the southwest (Kerala) coast of India were studied using biweekly sampling from the Pre-Monsoon (PRM) in April to ... -
Shift in the phytoplankton composition associated with reversal in east India coastal currents in the Bay of Bengal
(Elsevier, 2025)The alteration of phytoplankton composition due to variations in physical mixing, salinity, nutrient concentrations and their stoichiometric ratios would impact the overall ecosystem, affect the food web and influence the ... -
Marine biofilm microbial communities on deep-sea moorings as indicators of a changing environment
(Elsevier, 2025)Marine biofilms developed on buoys encasing Acoustic Doppler Current Profilers (ADCPs), deployed on deep-sea moorings for current measurements, were characterized for the first time along the continental slope of the west ... -
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 ...
