Methods and Instrumentation for In Situ Quantification and Sampling of Coastal and Deep-Sea Bioluminescent Organisms
(Springer, 2026)Since the first recorded observation of deep-sea bioluminescence by William Beebe and Otis Barton in the 1930s, the quantification of in situ bioluminescence has garnered significant global interest due to its wide-ranging ... -
Constraining the Origin of Primary Magma in Barren Island and Narcondam of Andaman Subduction Zone, NE Indian Ocean Using Arc Basalt Simulator 5 (ABS5)
(wiley Online Library, 2026)This review presents new insights on the origin of primary arc magma and its geochemical signatures in the Barren Island and Narcondam using Arc Basalt Simulator 5 (ABS5). Barren Island rocks are basalt to basaltic andesite ... -
Stratification and wind changes shape future Indian Ocean chlorophyll
(IOP Publishing, 2026)Large uncertainties in projected future changes of Indian Ocean chlorophyll across Earth System Models are largely attributed to differences in biogeochemical process representation. We show, however, that large biases in ... -
Pre-bomb marine reservoir corrections for the southeastern Arabian Sea
(Cambridge University Press, 2026)Estimates of marine reservoir corrections (?R) in the southeastern Arabian Sea region are limited. To better constrain the region s marine reservoir corrections, additional pre-bomb radiocarbon records are needed. In this ... -
Magnetic mineralogical and sedimentological approach for tracing source-to-sink processes in a tropical fluvial, estuarine, and marine system
(Elsevier, 2026)Magnetic minerals are ubiquitous in estuarine, coastal, and shelf systems and potential recorders of geological, climatic and sedimentary processes. Sediments in the tropical sedimentary system of Goa have been extensively ... -
Spatial-scale characterization of phytoplankton functional communities in the coral reef lagoons of Lakshadweep Archipelago: HPLC-CHEMTAX approach
(Springer, 2026)Phytoplankton biomarkers and functional group composition were characterized for the first time in the coral reef lagoons and adjacent open waters of the Lakshadweep Archipelago (LDA) during the winter monsoon of 2022, ... -
Source-specific health risks of metallic elements in road dust from coal mining affected urban areas using an integrated PMF HHR Monte Carlo framework
(Springer, 2025)Metallic element (ME) contamination in urban road dust poses critical environmental and health challenges, particularly in Dhanbad, eastern India, representing one of the most intensively coal-mining impacted urban regions ... -
Transformation of particulate matter while sinking through the oxygen minimum zone of the Eastern Arabian Sea,
(Elsevier, 2026)The degradation of particulate organic matter in the ocean plays a critical role in regulating the marine carbon cycle and sustaining oxygen minimum zones. In this study, suspended particulate matter from two stations in ... -
Cold seep induced elevated water column methane concentrations in Krishna-Godavari basin, Bay of Bengal
(Springer, 2026)Active cold seep sites associated with shallow methane hydrates, methane gas flares in the water column, and cold seep ecosystems have been reported from the Krishna-Godavari (K-G) basin along the eastern continental margin ... -
Eco-friendly Biosynthesis and Toxicity Assessment of Chitosan Silver Nanoparticles Derived from Chitin of Massive Tube Casing Blooms of Spiochaetopterus Sp
(Springer, 2026)Chitosan, a natural biopolymer with antibacterial properties and nanotechnological potential, is typically sourced from crustacean shells. This is the first study to identify polychaete Spiochaetopterus sp. tube casings ... -
Under-recognized impacts of abandoned, lost, and discarded fishing gear on threatened marine wildlife in the remote Andaman Islands, Bay of Bengal: A baseline study
(Elsevier, 2026)Abandoned, lost, or otherwise discarded fishing gear (ALDFG) poses a significant threat to marine biodiversity globally, yet its impacts in remote island ecosystems remain poorly documented. This study provides the first ... -
Impact of monsoon waves on the deposition of chitin tubes of polychaetes along the central-eastern Arabian Sea,
(Cambridge University Press, 2026)The west coast of India is highly productive during the southwest monsoon (SWM; June September), primarily due to coastal upwelling. While the SWM enhances pelagic productivity, it can also induce ecological disturbances ... -
Seasonal variations in phytoplankton community and the impact of physico-chemical variables in the estuaries of the central west coast of India.
(Taylor & Francis, 2026)The spatio-temporal variation of the phytoplankton community was investigated in the Mandovi and Zuari estuarine waters of Goa, India, from February 2021 to January 2022. A total of 160 phytoplankton species were identified ... -
Microbial and pathogenic indicators for pollution risk assessment in an urban estuary under dry and wet conditions
(Elsevier, 2025)Tropical estuaries are vital ecosystems, serving as biodiversity nurseries and supporting key ecological processes. Increasing anthropogenic pressures, however, have imposed unforeseen challenges on water resources in urban ... -
Export production in the upper ocean using f-ratios in the Bay of Bengal using a remote sensing approach
(Elsevier, 2026)The fraction of the primary production leaving the photic zone is important to understand the strength of the biological pump and carbon sequestration. This fraction intensifies the oxygen minimum zone by supporting life ... -
Monitoring and modeling leachate characteristics in simulated landfill conditions: Assessing tropical region impacts on solid waste degradation and pollution risks for climate resilient landfill management,
(Elsevier, 2025)The widespread use of open dumping systems worldwide poses notable risks to groundwater and surface water supplies and increases air pollution. The current research lacks a comprehensive understanding of the biodegradation ... -
Methane dynamics in the southeastern Arabian Sea: Patterns of distribution and annual emission estimates,
The production pathways and sea-to-air fluxes of climate-relevant trace gases, including methane (CH4), in the southeastern Arabian Sea (SEAS), are poorly addressed and suffer significant uncertainties due to their spatial ... -
Macrofaunal communities of a unique sedimentary environment: The Alappuzha mudbank, southwest coast of India
Mudbanks are unique, transient coastal phenomena characterised by calm, turbid waters and high productivity, frequently reported along the southwest coast of India, especially along the Kerala coast. The Alappuzha mudbank, ... -
Spatio-temporal dynamics of tropical phytoplankton communities in the diverse coastal environments of southwestern India: HPLCCHEMTAX approach
(Elsevier, 2025)A comprehensive investigation on phytoplankton community composition, utilizing HPLC-derived biomarker pigments and CHEMTAX analysis, was conducted in the Chandragiri Estuary (CGE) and adjacent nearshore waters (<20 m, off ... -
Pyritization may archive the influence of Sulfate-AOM and bioturbation activities in marine sulfidic shelf sediments
Organoclastic sulfate reduction and anaerobic oxidation of methane (AOM) coupled to sulfate reduction (SO42--AOM) are key processes regulating organic matter degradation and methane (CH4) consumption in marine sediments. ...
