Bacterial Dynamics in the Northern Indian Ocean Region: Understanding from the Pre-genomics to Present-Day OMICS Era
(Taylor & Francis, 2025)The Northern Indian Ocean (NIO) is one of the most characteristic regions of the world oceans with diverse oceanographic features. Understanding of the microbial community structure in these unique habitats has rapidly ... -
Diversity and ecology of pollution tolerant phytoplankton along Patalganga estuary, West Coast of India
(Elsevier, 2025)The present study aimed to comprehend the seasonal diversity and distribution of the phytoplankton community influenced by organic matter through point and non-point sources in different salinity regimes of the Patalganga ... -
Advances in chemical and microbial source tracking (MST) of fecal pollution in coastal waters: a review
(Springer, 2025)Coastal waters are the ultimate destination for both point and non-point sources of contamination. The uncontrolled dicharge of fecal waste into the ocean harms natural resources, marine life, and poses health risks to ... -
Assessing CMIP Models Ability to Detect Observed Surface Warming Signals Related to Climate Change
(American Metrolgical Society, 2025)Assessing if CMIP models can detect observed climate change signals is crucial for evaluating their realism and strengthening confidence in future projections. These signals can only be compared once distinguishable from ... -
Suboxic waters of the eastern Arabian Sea shelter secondary chlorophyll maximum dominated by heterotrophic dinoflagellate Pronoctiluca spp. (order Noctilucales)
(Springer, 2025)Suboxic waters of the eastern Arabian Sea shelter secondary chlorophyll maximum dominated by heterotrophic dinoflagellate Pronoctiluca spp. (order Noctilucales) -
Ecological characterization of an unusual red tide (dinoflagellate-cyanobacterium consortium) in the coastal waters of Vizhinjam, southwest coast of India
(Springer, 2025)An extensive reddish discoloration was observed in the nearshore waters (20 30 m depth) of Vizhinjam, located on the southwest coast of India, during the last week of October 2023. Microscopic analysis identified Ornithocercus ... -
Do the swells from the Arabian Sea intrude into the Arabian Gulf through the Strait of Hormuz?
(Springer, 2025)This study derives the long-term climatology of significant wave heights and mean wave periods of swells, wind seas and resultant waves in a domain covering the Arabian Gulf, Strait of Hormuz (SoH), Sea of Oman and northern ... -
History of recurrent short- and long-term coral bleaching events in Indian coral reefs: A systematic review of contrasting bleaching patterns, lessons learned, and future directions
(Elsevier, 2025)Climate change has intensified coral bleaching events globally and caused widespread coral mortality; however, bleaching patterns and species susceptibility vary across locations and over time. Understanding these spatial ... -
Distribution of organic matter and diatom frustules (diversity, flux) along the western Indian continental shelf related to contrasting physicochemical settings
(Elsevier, 2025)The western Indian continental shelf (eastern Arabian Sea) exhibits contrasting biogeochemical features. This area becomes highly productive due to summer monsoon-driven coastal upwelling in the south and winter monsoon-induced ... -
Impact of seasonal anoxic events on phytoplankton dynamics over the Western Indian shelf: An intra- and inter-annual study
(Elsevier, 2025)Coastal deoxygenation impacts phytoplankton communities crucial for marine productivity. The inter- and intra-annual variability in phytoplankton communities at a shallow (27 m) station over the Western Indian Shelf (CaTS ... -
Re-evaluation of the spherules proposed origin recovered from the Pacific Ocean site of the CNEOS 2014-01-08 (IM1) bolide
(Elsevier, 2025)In a recent publication by Loeb et al. (2024), the collection of spherules from the Pacific Ocean was classified as extraterrestrial, specifically micrometeorites. We critically evaluate their findings and conclusions, ... -
Land Use Land Cover structural impact on abundance of antibiotic resistant Bacillus species in Tropical Estuary of India
(Elsevier, 2025)In recent decades, the Land Use Land Cover (LULC) in the coastal environment along with ambient scenario of metocean condition has been considered as one of prime factors in distribution and diversity of biota. Antibiotic ... -
Chemical characteristics and bioactivity potential of polysaccharide extracts and purified fractions from Arctic brown macroalgae
(Elsevier, 2025)Macroalgae growing in the polar regions are exposed to extreme environment conditions and may induce differences in the structural and bioactive properties of their polysaccharides. Six brown macroalgae viz. kelp species ... -
Determining chlorophyll-a thresholds for characterizing algal bloom conditions: An ocean colour remote sensing approach
(Elsevier, 2025)The Indian coast has been experiencing an increase in algal bloom events over the decades. Owing to the regional and seasonal dynamics of algal biomass (proxy: chlorophyll-a, hereafter chl-a), a multitude of thresholds of ... -
Microstructures along the Indian west-coast continental shelf: layering and vertical mixing
(Elsevier, 2025)During the month of October, the West Indian Coastal Current (WICC) is in a stage of transition from equatorward to poleward flow. The sea surface salinity near the Indian Coast is lower in the south compared to the north. ... -
Reduced bottom water oxygenation in the northern Indian Ocean during the Last Glacial Maximum
(Elsevier, 2025)Reconstructing variations in the past bottom water oxygenation of the oceans is crucial for understanding the current global ocean deoxygenation and increased respired carbon storage. Changes in the deep water circulation ... -
Characterization of fatty acid composition of healthy and diseased coral mucus released from host and/or endosymbiont for their possible role in coral health
(Springer, 2024)Coral mucus serves as a barrier, protecting corals from a variety of biotic and abiotic stresses. Coral mucus contains all essential nutrients including carbohydrates, amino acids and fatty acids (FA). Although fatty acids, ... -
Unveiling the chromate stress response in the marine bacterium Bacillus enclensis AGM_Cr8: a multifaceted investigation
