Wave energy potential along the Indian coast: A comprehensive review
(Elsevier, 2024)Wave energy is rapidly emerging as a promising and innovative solution among the various renewable energy sources. Given India's extensive coastline, including islands, research on wave energy is essential to harness this ... -
An evaluation of glass beads from the southwestern coastal state of Goa, India, as a potential pollutant in marine ecosystem
(Springer, 2024)Glass beads laid on the road, mainly used for better visibility, can contribute to harmful anthropogenic waste to the marine environment, and it is a prerequisite to distinguish the chemical properties associated with it. ... -
Application of functional metagenomics in the evaluation of microbial community dynamics in the Arabian Sea: Implications of environmental settings,
(Elsevier, 2024)Ocean microbial communities form the base of marine food webs, facilitating energy transfer and nutrient cycling, thereby supporting higher trophic levels. We investigated their composition and functional profiles across ... -
Assessment of transboundary macro-litter on the remote island of Andaman and Nicobar: Unveiling the governing factors and risk assessment
(Elsevier, 2024)The increasing occurrence of mismanaged plastic litter along India's coastline and the ominous challenges it poses to biodiversity and ecosystem health is a growing environmental concern. To address this issue, we ... -
Dissolved and suspended nutrient complexity in an urbanized creek-estuary confluence: Implication on water quality alteration
(Elsevier, 2024)The Thane Creek-Ulhas estuary confluence region acts as a naturally active infiltration system, crucial for altering water quality in the area and Arabian Sea. Particle-water exchange, hydrodynamics, and anthropogenic ... -
Ecophysiological status of copepods in the oxygen minimum zone of Eastern Arabian Sea
(Elsevier, 2024)Eutrophication of marine ecosystems is a global problem, particularly in a changing climate and the spreading of Oxygen Minimum Zones (OMZs). The eastern Arabian Sea has both seasonal and permanent/perennial OMZs, but our ... -
An unusual lunar origin and chondritic refractory Antarctic micrometeorites
(Elsevier, 2024)We report unearthing the first silicate-type (S-type) lunar Antarctic micrometeorites (AMM) spherule and another spherule with a refractory chondritic phase. The lunar spherule is made of Augite with minor Ni magnetite (<1 ... -
Seasonal intensification of oxygen minimum zone: linking Godavari River discharge to fall hypoxia in the Bay of Bengal
(FRONTIERS MEDIA SA, 2024)This study investigates the biogeochemical impact of Godavari River discharge (GRD) on the Bay of Bengal (BoB), focusing on the formation of an intense and shallow oxygen minimum zone (OMZ) near the river mouth during the ... -
Seasonal Surges in Bacterial Diversity along the Coastal Waters of the Eastern Arabian Sea
(MDPI, 2024)The upwelling phenomenon plays a vital role within marine ecosystems, transporting essential nutrients from the bottom to the surface and boosting biological productivity. However, the bacterial community structure in ... -
The role of the Andaman Nicobar fault (ANF) in shaping Narcondam offshore: Insights from high-resolution reflection seismic data
(Elsevier, 2024)The study investigates the Andaman Nicobar Fault (ANF) and its role in the evolution of a volcano-supported basin adjacent to Narcondam Island, using three high-resolution 2D seismic reflection profiles. Migrated images ... -
Size-Fractionated Phytoplankton Biomass in Port Blair Bay, South Andaman Island: Spatial Variability and Environmental Control
(Springer, 2024)Island bays show different physico-chemical characteristics due to their connection with open ocean water and small catchment area, and the same is expected with the biological forms. Phytoplankton size structure significantly ... -
Microbial distribution in Mudbank regions off Alappuzha, South-West coast of India
(Springer, 2024)The coastal waters of Kerala, in the South Eastern Arabian Sea (SEAS), are unique during the Southwest monsoon season due to the concurrent occurrence of two physical processes, the upwelling and Mudbanks. However, little ... -
Analyzing the rainfall trend and hydroclimatic teleconnections using Hilbert Huang Transform for the coastal smart cities of India
(Elsevier, 2024)The changing climatic patterns associated with intense and erratic rainfall have led to high flooding risk in urban areas. Identifying these hydro-meteorological risks in cities is a matter of concern for decision-makers. ... -
Discovery of fossil micrometeorites from the Deccan trap intertrappeans
(Wiley Online Library, 2024)Abstract The Cretaceous?Paleogene (K-Pg) boundary represents the extinction of ~70% of species, a prominent Chicxulub impact event and Deccan volcanism. This work reports the first attempt to extract the micrometeorites ... -
Tracing marine and terrestrial biochemical signatures of particulate organic matter in an Arctic fjord (Kongsfjorden)
(Elsevier, 2024)Arctic fjords are hotspot for organic matter (OM) transformation and storage, however, the composition and sources of the particulate organic matter (POM) are still not completely understood. Further, due to the ongoing ... -
A Northgrippian sedimentary magnetic enhancement along the western margin of India
(Elsevier, 2024)Sedimentary magnetic records of shelf region contains complex environmental evolution information, necessitating records from various global regions to accurately interpret its significance. A sediment core (SSD-39/GC-01) ... -
Assessment of Benthic Meiofauna in Multi-Stressed Environment of a Tropical Estuary: a Case Study Using Low Taxonomic Resolution Data
(Springer, 2024)The estuary receives varying anthropogenic inputs that significantly influence the benthic biota and suppress ecological health. Thus, multiple parameters (natural and anthropogenic) and meiofaunal community structures ... -
Seasonal shift in trophic status induced by bacterial metabolic activity in tropical mangrove-dominated estuaries of Southwest India
(Springer, 2024)Mangroves are highly productive ecosystems that supply carbon and nutrients to the coastal food web from autochthonous and allochthonous sources. The fluctuations in the quantity of these sources influence bacterial metabolic ... -
Biogeochemical cycling of iodine in the Bay of Bengal: A comparison with the Arabian Sea
(Elsevier, 2024)Iodine is a redox-sensitive element and a potential oxidant for the respiration of organic matter. Here we report the spatial variation of dissolved iodine in the Bay of Bengal (BoB) oxygen minimum zone (OMZ) and compare ... -
Preparation and Characterization of Agar Polysaccharide from Red Alga Phycocalidia Vietnamensis (Bangiales)
(Springer, 2024)In this research, biomass of the red algae Phycocalidia vietnamensis (Bangiales) was investigated for agar production. Agar was prepared by the hot water extraction method with 0, 4, 6, 8, 10% (w/v) NaOH pre-treatments. ...
