"Trophic switch" by catfish community from predation to scavenging modulated by human food discard in an estuarine bay
(Springer, 2024)Benthic predatory catfishes are voracious and opportunistic predators and can easily shift their diet according to the availability of prey. In this study, feeding ecology of catfishes from two adjacent habitats of an ... -
Role of intersecting equatorial and coastal waveguides near sri lanka on intraseasonal sea level variability along the West Coast of India
(John Wiley & Sons, Ltd, 2024)The sea level variations along the west coast of India (WCI) significantly affect the ecosystems and fisheries, because of their tight coupling with the oxycline depths in this region, which hosts the world's largest natural ... -
Characterization of bioactive porphyran oligosaccharides produced using porphyranase from Bacillus sp. NIOA284
(Elsevier, 2024)Macroalgae associated bacteria are the major source of polysaccharide hydrolyzing enzymes for efficient bioutilisation of macroalgal biomass. In this study, extracellular porphyranase, PB1 isolated from a macroalgae ... -
Strong climate control on the millennial-scale dust variability and sediment provenances in the Equatorial Indian Ocean inferred from Sr-Nd isotopes
(John Wiley & Sons, Ltd, 2024)High-resolution Sr and Nd isotope compositions along with major and trace element abundances have been analyzed in silicate fraction of sediments core, SSD004-GC03, from the Equatorial Indian Ocean (7.2°N and 77.9°E) at ... -
Trends in the surface wind-wave heights in the North Indian Ocean based on 50-year NCEP/NCAR reanalysis wind-wave data
(Elsevier, 2024)Analysis of 50 years of hourly significant wave heights of the Indian Ocean between 30�N and 60�S is carried out and linear trends of mean significant wave heights and maximum significant wave heights are obtained on annual, ... -
Fishing harbours as a source of PAHs pollution: A case study from Veraval harbour, west coast of India
(Springer, 2024)Worldwide, studies on polycyclic aromatic hydrocarbons (PAHs) especially focusing on fishing harbours have been found in a limited magnitude only. The characteristics of 16 PAHs and their associated ecological adversities ... -
Morphotectonics of the Raman-Panikkar-Wadia seamount chain in the Laxmi Basin, Eastern Arabian Sea
(Elsevier, 2024)The Laxmi Basin, which is a deep ocean basin situating adjoining to the northwestern continental margin of India, contains a linear seamount chain consisting of the Raman Seamount, Panikkar Seamount and the Wadia Guyot, ... -
Beneficial properties of mucus in coral adaptations and ecological interactions
(Springer, 2024)Coral mucus secreted by mucocytes provides a protective physicochemical and physiological barrier between coral tissue and external environmental threats. The biomolecules and nutrients of the secreted mucus are derived ... -
Antimicrobial activity of coral-associated beneficial bacteria against coral disease-causing microbial pathogens
(John Wiley & Sons, Ltd, 2024)Microbial infection of immune-compromised corals influences disease severity, resulting in coral mortality. However, coral-associated beneficial bacteria are known to produce antimicrobial compounds that prevent the growth ... -
Export of particulate organic carbon and nitrogen to the northern Indian Ocean by the monsoonal rivers of India
(Springer, 2023)This study analyses particulate organic carbon (POC) and particulate nitrogen (PN) export from Indian monsoonal rivers to the north Indian Ocean. Indian monsoonal rivers export approximately 1.2 Tg yr−1 (1Tg = 1012 g) of ... -
Ocean surface wave dynamics off the southern tip of Indian mainland
(Elsevier, 2023)Waves collected in the nearshore waters off the southern tip of the Indian mainland from February 2018 to January 2019 are used to examine the wave spectral characterization. The annual mean of the significant wave height ... -
Changes in rock magnetic properties of sediments along the Carlsberg Ridge: Inferences on active/extinct vent fields
(Elsevier, 2024)Hydrothermal vents at Mid Ocean Ridges (MOR) are known to leave metalliferous, bacterial, temperature-induced signatures in sediments. Knowledge of active/extinct vents along the Carlsberg Ridge (CR) is sparse; further ... -
Spatiotemporal variability in phytoplankton size class modulated by summer monsoon wind forcing in the Central Arabian Sea
(John Wiley & Sons, Ltd, 2024)The Arabian Sea is an area of intense ocean-atmospheric coupling that impacts its physicochemical, and biological processes. During the summer monsoon (June-September), in the central Arabian Sea, a low-level atmospheric ... -
Variation of amino acid in the sinking particulates in the northeastern Arabian Sea and the northern Bay of Bengal
(Elsevier, 2023)Sediment traps are widely used to get insight into how particulate matter forms and settles in the water column. Earlier studies in the Northern Indian Ocean have shown that the sinking flux depends mainly on surface primary ... -
Environmental variables and its association with faecal coliform at Madh Island beaches of megacity Mumbai, India
(Elsevier, 2024)The abundance of fecal-indicating bacteria in water bodies are said to be influenced by environmental conditions. The effect of environmental parameters on the changing microbial population plays an important role in coastal ... -
