Higher environmental stability makes the Gulf of Mannar a biodiversity hotspot
(Elsevier, 2025)The Gulf of Mannar (GoM), located between India and Sri Lanka, is a biodiversity hotspot and the first Indian marine biosphere reserve. Despite its location at the confluence zone of the Southeastern Arabian Sea (SEAS) and ... -
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 ... -
Pelagic iodine cycling over the Western Indian margin: Impact of anoxic events and benthic flux
(Elsevier, 2025)The iodine cycling in marine environments plays a crucial role in oceanic biogeochemical processes and atmospheric chemistry. Excess iodine has been reported previously in both the perennial and seasonal oxygen minimum ... -
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�sp. ... -
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 ... -
Ecological features of zooplankton (copepods) in the perennial oceanic oxygen minimum zone in the Eastern Arabian Sea
(Elsevier, 2025)Copepods are the most abundant metazoan/mesozooplankton in the ocean and are adapted to survive in diverse environmental conditions. Exclusive studies on copepods in the Eastern Arabian Sea (EAS) with emphasis on their ... -
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 ... -
Hypothesis-driven sensitivity analysis of Delft3D flexible mesh hydrodynamic model: insights into coastal processes in the monsoonal tropical Goa Coast, India
(Springer, 2025)Accurate numerical modeling of coastal hydrodynamics in tropical monsoonal environments remains challenging because of parameter uncertainties and nonlinear process interactions. This study presents a hypothesis-driven, ... -
Delta under pressure: A holistic assessment of morphodynamic change in the Indian Sundarbans from 1972 to 2025
(Elsevier, 2025)The Indian Sundarban Delta (ISD), located at the confluence of the Ganga-Brahmaputra-Meghna river system along India's eastern coast, is among the world's most geomorphologically dynamic and environmentally vulnerable ... -
The role of macroalgae in modulating coral calcification: Mixed species responses in a changing reef environment
(Elsevier, 2025)The ever increasing dominance of macroalgae on coral reefs is posing new challenges for coral growth and reef resilience. As a part of the continuous coral community monitoring program in Gulf of Mannar Marine Biosphere ... -
Picophytoplankton community characteristics at the subsurface chlorophyll maxima in the Northern Indian Ocean
(Elsevier, 2025)Autotrophic picoplankton are integral to marine ecosystems, contributing nearly half of oceanic primary productivity, particularly in warm, oligotrophic regions. Given that subsurface chlorophyll maxima (SCM) account for ... -
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 ... -
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 ... -
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 ... -
Rhizosphere microbiomes and carbon dynamics in mangrove ecosystems are shaped by host species, patch age, and environmental drivers
(Elsevier, 2025)Mangrove rhizosphere bacterial communities play critical roles in organic matter remineralization and carbon dynamics. This study characterized the rhizosphere bacteriomes of 11 major mangrove species, from the estuarine ... -
Zebrafish as a model for SARS-CoV-2 infection, pathogenesis, transmission, and drug screening
(Elsevier, 2025)Causative agent, Severe acute respiratory syndrome coronavirus - 2 (SARS-CoV-2) requires a host for its infection, replication, and spread. With the availability of several animal models and their limitations, there is a ... -
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 ... -
Antibiotic-resistant bacteria in marine productive zones of the eastern Arabian Sea: Implications for human and environmental health
(Elsevier, 2025)The increasing threat of antibiotic resistance is a major global concern affecting human and environmental health. Marine environments, though underexplored, are emerging as significant reservoirs for antibiotic resistance ... -
