Seasonal nutrient loadings in four monsoonal micro/meso tidal tropical estuaries, west coast of India,
(Elsevier, 2024)Nutrient concentrations were studied seasonally along estuarine and fluvial regions of four micro/meso tidal rivers from Karnataka and Maharashtra, west coast of India. This study was performed to assess the pathway of ... -
Biogeochemical Reconstruction of Authigenic Carbonate Deposits at Methane Seep Site off Krishna-Godavari (K-G) Basin, Bay of Bengal
(Wiley Online Library, 2024)Abstract Active and relic marine methane-seep sites are widely distributed globally and are distinguished by distinctive geology, biogeochemistry, and ecosystems. The discovery of methane-seep sites in the Krishna-Godavari ... -
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 ... -
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 ... -
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. ... -
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 ... -
Macrobenthic communities in the polymetallic nodule field, Indian Ocean, based on multicore and box core analysis
(FRONTIERS MEDIA SA, 2024)Managing deep-sea mining is challenging due to limited data on species and habitat distribution, hindering decision-making. In less-explored polymetallic nodule sites in the Indian Ocean, management approaches are deemed ... -
Evaluation of the proximate composition and antioxidant capacity of some seaweeds from the Konkan coast of India
(Elsevier, 2024)Minerals, antioxidants, and other nutrients that promote health can be found in abundance in seaweeds. In this study, we evaluated the proximate composition and antioxidant capacity of some seaweeds from Konkan coast of ... -
Delineating morphological traits of oceanic micro-phytoplankton as potential ecological indicators
(Elsevier, 2024)The micro-phytoplankton (>20 ?m) adaptations and resilience were assessed using morphological traits (shape, surface-to-volume ratio; S:V, and greatest-axial-linear-dimension; GALD) from sea-surface and different SCML-depths ... -
Production of marine-derived bioactive peptide molecules for industrial applications: A reverse engineering approach
(Elsevier, 2024)This review examines a wide range of marine microbial-derived bioactive peptide molecules, emphasizing the significance of reverse engineering in their production. The discussion encompasses the advancements in Marine ... -
Bomb-radiocarbon in the Northern Indian Ocean
(Elsevier, 2024)Bomb-radiocarbon is a useful tracer to study ocean circulation and air-sea CO2 exchange processes. In the present study bomb radiocarbon distribution in dissolved inorganic carbon of the Northern Indian Ocean around late ... -
Indian Ocean Acidification and Its Driving Mechanisms Over the Last Four Decades (1980 2019)
(Wiley Online Library, 2024)Abstract This paper aims to study the changes in the Indian Ocean seawater pH in response to the changes in sea-surface temperature, sea-surface salinity, dissolved inorganic carbon (DIC), and total alkalinity (ALK) over ... -
Impact of river discharge and suspended sediments on the nearshore benthic environment along the Indian southwest coast
(Elsevier, 2024)River discharge into the sea and its implications on the environmental setting and fauna in the nearshore represent the intricate interactions among the atmosphere, hydrosphere, lithosphere, and biosphere. This study, based ... -
Polychlorinated biphenyls in the surface and deep waters of the Southern Indian Ocean and Coastal Antarctica
(Elsevier, 2024)Polychlorinated biphenyl compounds (PCBs) are industrial chemicals whose production was discontinued in the early nineties in most countries. Sill, PCBs are detectable in pristine and remote locations. Occurrence in regions ... -
