Variabilities in the estimate of 100-year return period wave height in the Indian shelf seas
(Springer, 2024)Exploring the variability in design wave heights through extreme value analysis is crucial for understanding extreme oceanographic conditions and is paramount for the safe design and operation of offshore structures. This ... -
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, ... -
Production of quality biomass of Gelidium micropterum K tzing through optimization of nutrients and salinity for sustainable land-based cultivation
(Springer, 2024)In this study, the seeding density (w/v), Provasoli Enriched Seawater (PES) medium strength, and salinity of the culture medium were optimized to obtain higher growth rates and superior biomass quality of Gelidium micropterum ... -
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 ... -
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. ... -
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 ... -
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 ... -
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. ... -
Polycyclic aromatic hydrocarbons in surface sediments of the western Bay of Bengal: Distribution, sources, and ecological risk assessment
(Elsevier, 2024)This study investigated the distribution, sources, and ecological risk of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments of the Western Bay of Bengal (WBoB). Coastal, shelf and slope sediments from the ... -
Ruthenium-catalyzed synthesis of novel phenoxy(phenyl)-1H-benzo[d]imidazoles: Spectral characterization and DFT studies
(Elsevier, 2024)The synthesis of a series of novel phenoxy(phenyl)-1H-benzo[d]imidazoles by oxidative cyclization of phenoxybenzaldehyde and diamine in the presence of ruthenium(II)-catalysts is described. The transformation using a ... -
