(Elsevier, 2025)A sporadic outbreak of the bioluminescent dinoflagellate Noctiluca scintillans (NS) occurred in the Mandovi estuary along the Goa coast of the Central Eastern Arabian Sea on 24th May 2023, prompted by pre-monsoon upwelling, ... -
Anthropogenic stressors of black clam distribution in Kochi backwaters on the Indian west coast
(Springer, 2025)The black clam (Villorita cyprinoides Gray, 1825) is the most commercially important clam in India and the major share of its landing (around 25,000 tonnes/year) comes from Kochi backwaters (KBW), the largest estuarine ... -
Seasonal dynamics and environmental drivers of productivity in the Cochin Estuarine System: Insights from estuarine turbidity maxima
(Elsevier, 2025)The Cochin estuarine system, characterised by its Estuarine Turbidity Maximum (ETM) zones, undergoes significant seasonal variations influenced by riverine input and tidal forces. This study examined the seasonal shifts ... -
Dinoflagellate cyst and nannofossil imprints in the middle Eocene Kirthar transgressive strata from the western Garo Hills, South Shillong Plateau, India
(Elsevier, 2025)One of the global characteristic features of the Eocene is the extensive development of carbonate platforms in various regions of Tethys. Paleogene sequences of the Shillong Plateau from west to east are exposed in the ... -
Diapycnal oxygen flux in the oxycline region of the core of the Arabian Sea Oxygen Minimum Zone
(Elsevier, 2025)This study quantified the relative contributions of double diffusion and shear-driven mixing on the diapycnal oxygen flux in the oxycline region of the core of the Arabian Sea Oxygen Minimum Zone (OMZ), a critical oceanic ... -
Bacterial communities and their functional profiles from mangroves, a blue carbon ecosystem and terrestrial forest habitats
(Springer, 2025)Microorganisms play a crucial role in the biogeochemical cycling of organic matter through their heterotrophic activity. This study delves into comparing the sediment bacterial communities from the mangrove habitats of ... -
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 ... -
Comparative Assessment of Heavy Metal Contamination and Pollution Trends in Indian Estuarine Sediments: Insights from East and West Coasts of India
(ACS Publications, 2025)This study presents a comparative assessment of heavy metal contamination in sediments from major Indian estuaries in recent decades. Metal concentration data were compiled from published literature and analyzed for Pb, ... -
Climatology and Trends of Various Oceanic and Atmospheric Parameters in the Arabian Sea Over the Last 45?Years
(Wiley, 2025)This study investigates the timescale variability of key atmospheric and oceanic variables in the Arabian Sea (AS) using 45?years (1979�2023) of data. Analyzing sea surface temperature (SST), wind components, precipitation, ... -
Contrasting Historical Trends in Equatorial Indian Ocean Zonal Sea Surface Temperature Gradient in CMIP6 Models
(Wiley, 2025)The zonal sea surface temperature (SST) gradient in the tropical Indian Ocean (TIO) has been assessed using 50 climate models. Among these, 38 models exhibit an east�west negative gradient trend, indicating an intensified ... -
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 ... -
