(Wiley Online Library, 2024)The present study explored the dynamics of total dissolved Cobalt (dCo) in the Indian Ocean, revealing different distribution patterns in the different sub-basins, nutrient-type in the southern sector, hybrid-type in the ... -
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 ... -
Unveiling the chromate stress response in the marine bacterium Bacillus enclensis AGM_Cr8: a multifaceted investigation
(Springer, 2024)In this study, we introduce Bacillus enclensis AGM_Cr8, a gram-positive marine bacterium isolated from the chronically polluted Versova Creek in Mumbai, India. AGM_Cr8 exhibits robust tolerance to chromate stress, thriving ... -
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. ... -
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 ... -
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 ... -
Substantial invasion of Antarctic Intermediate Water into the Arabian Sea during Younger Dryas and Heinrich Stadials
(Elsevier, 2024)Antarctic Intermediate Water (AAIW) is an important component of the global thermohaline circulation and an essential limb of the Atlantic Meridional Overturning Circulation (AMOC), which redistributes heat, oxygen, and ... -
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. ... -
Investigating the evolution of sand bars and natural channel formation in the Mandovi estuary along the central west coast of India
(Elsevier, 2024)Coastal formations, such as sandbars, play a vital role in shaping the environment and maintaining local and regional coastal morphology. This study deals with two noteworthy sandbars, namely Aguada and Reis Magos which ... -
Tracing marine and terrestrial biochemical signatures of particulate organic matter in an Arctic fjord (Kongsfjorden)
