Unravelling the mechanism of transient coastal upwelling in the southeastern Arabian Sea triggered by Cyclone Michaung
(?Institute of Physics Publishing, 2025)Cyclone Michaung formed and passed over the Bay of Bengal in early December 2023. In the current study, we investigated the dramatic changes in physical-biogeochemical conditions in the Southeastern Arabian Sea - and the ... -
Phytoplankton Community in Contrasting Hydrological Features of the Tropical Meandering River Chapora, Central West Coast of India
(Springer, 2025)This study examines the distribution and composition of phytoplankton in the tropical river Chapora under its intricate physicochemical characteristics. The river s meandering character resulted in a unique zonation of ... -
Spatial Variability of Ground Deformation of Coastal Regions of the Krishna Delta, East Coast of India Using SAR Interferometry
(Springer, 2025)The Deltas of the east coast of India are highly susceptible to vertical deformations due to various factors like hydrological changes, reduced sediment inflow from rivers, groundwater exploitation, hydrocarbon extraction, ... -
Recent Developments in Metal-Organic Frameworks for Water Purification: A Mini Review
(Wiley Online Library, 2024)Abstract Heavy metals, pharmaceuticals, microplastics, dyes, and radionuclides in wastewater increasingly threaten environmental sustainability. Metal-organic frameworks (MOFs) are versatile materials for mitigating these ... -
First report and molecular description of Amygdalum anoxicolum from a seamount in the eastern Arabian Sea
(Cambridge University Press, 2025)This paper reports one mytiloid species, Amygdalum anoxicolum P. G. Oliver, 2001 from the summit of a seamount located in the eastern Arabian Sea. This species was encountered from the core of the Arabian Sea oxygen minimum ... -
Implications of coastal upwelling and mud banks on the structuring of phytoplankton communities in the nearshore waters of Alappuzha, southwest coast of India
(Elsevier, 2025)A comprehensive study on phytoplankton dynamics, encompassing chlorophyll a biomass, primary productivity, and community composition and abundance, was conducted in the Alappuzha mud bank region (< 15 m depth) along the ... -
Paleoarchean continental crust formation by reworking of juvenile crust: Evidence from SE part of Singhbhum Craton, eastern India
(Elsevier, 2025)Formation, evolution, and preservation of early continental crust have been a subject of intense debate. This is testified by the fragmentary nature of our understanding on the composition of early earth mantle, temporal ... -
Observed sea level and currents in the Indo-Sri Lanka channel: Seasonal transport, tidal characteristics, and the role of remote forcing,Estuarine, Coastal and Shelf Science,
(Elsevier, 2025)This paper examines the recorded sea level and current data in the Indo-Sri Lanka channel from 2010 to 2011. The shallow channel, which includes Palk Bay, Pamban Pass, and the Gulf of Mannar shelf plays a crucial ecological ... -
Tropical cyclones enhance net CO2 sink in the Bay of Bengal
(Elsevier, 2025)Tropical cyclones modify the upper ocean due to significant mixing associated with increased winds that bring CO2 and nutrient-rich subsurface waters to the surface, altering CO2 flux and biological production. In the ... -
Assessing the potential effects of climate change on the morphodynamics of the tropical coral reef islands in the Gulf of Mannar, Indian Ocean
(Elsevier, 2025)Low-lying and small tropical coral reef islands around the world are extremely vulnerable to the effects of global environmental change caused by the combination of anthropogenic climate change and escalating extreme ... -
Assessment of hazardous microplastic polymers and phthalic acid esters in an invasive mollusk (Mytella strigata) from the Cochin estuary, southwest coast of India: Unraveling ecosystem risks
(Elsevier, 2025)This paper characterizes the abundance, chemical characteristics, and potential hazards of microplastics (MPs) in water, sediment, and Mytella strigata from the Cochin Estuary (CE). In parallel, concentrations of plastic ... -
Response patterns of benthic functioning in tropical estuaries under varying scales of anthropogenic perturbations,
(Elsevier, 2025)Multifarious human pressures can adversely impact estuaries' benthic functioning, yet this is less understood in tropical regions. This study examined the macrobenthic functional patterns of three differentially impacted ... -
Unveiling the risk of marine litter and derelict fishing gear in remote coral reefs of the Andaman and Nicobar Islands, North Indian Ocean
(Elsevier, 2025)An increasing amount of plastic litter and derelict fishing gear in the global oceans poses significant threats to corals and reef-associated marine biota. In this context, an underwater marine litter survey was conducted ... -
Chemical composition of aerosols over the Arabian Sea based on global reanalyses data and on-board ship measurements,
(Elsevier, 2025)The knowledge of chemical composition of atmospheric aerosols is key to understand aerosol-cloud-climate interactions and surface water biogeochemistry in the oceanic regions. Despite of strong natural and anthropogenic ... -
Comparative study of magnetic properties of sediments from six monsoonal rivers during the wet and dry periods, west coast of India,
(Elsevier, 2025)Environmental magnetism, in combination with Scanning electron microscopy (SEM) and X-ray diffraction (XRD), was carried out on the surface sediments of six rivers from the Goa and Karnataka regions (India). The main focus ... -
