Influence of the extreme Indian Ocean dipole 2019 on the equatorial Indian Ocean circulation.
(Springer, 2024)This study examines direct current measurements in the central equatorial Indian Ocean during the positive phase of the extreme Indian Ocean Dipole (pIOD) in 2019. Analysis of near-surface zonal current at 77E and 83E ... -
Impact of the Pacific-Japan pattern on the tropical Indo-western Pacific Ocean surface waves
(Springer, 2024)The present study examines the impact of the Pacific-Japan (PJ) pattern on tropical Indo Western Pacific Ocean significant wave heights during the boreal summer season (June through August, JJA) for the first time. The PJ ... -
Distribution and sea-to-air fluxes of nitrous oxide and methane from a seasonally hypoxic coastal zone in the southeastern Arabian Sea
(Elsevier, 2024)The seasonal variability, pathways, and sea-to-air fluxes of nitrous oxide (N2O) and methane (CH4) in the coastal environment, where coastal upwelling and mudbanks co-exist are presented based on the monthly time-series ... -
Plankton diversity and dynamics in the upper surface of the Indian sector of the Southern Ocean ecosystem and biogeochemical processes
(Elsevier, 2023)In the Southern Ocean (SO) marine ecosystem, the interplay between CO2 sink and climate change is closely linked to the shifting plankton communities, leading to potentially wide-ranging biogeochemical effects. Within the ... -
Behaviour of barium in the tropical estuaries: Implications to its marine budgets and paleo-oceanographic applications
(Elsevier, 2023)Marine Barium (Ba) is extensively used as a tracer for biogeochemical processes and paleo-oceanographic proxy for past river discharge, salinity, and long-term hydrological changes. However, poor constrain on the riverine ... -
Petrogenesis of submarine volcanic arc rocks from Andaman subduction zone, Northeast Indian Ocean: Constraints from slab components and mantle wedge characteristics
(Elsevier, 2024)The present study provides new petrological and geochemical data of the dredged rocks from submarine volcanoes along the Andaman arc and describes the petrogenetic evolution of the arc system in terms of mantle wedge ... -
Shell size variation of pteropod Heliconoides inflatus: Inferences on Indian Ocean carbonate chemistry during late quaternary
(Springer, 2024)The current study is an effort to understand the relationship between the average shell size and Limacina Dissolution Index (LDX) of pteropod species, Heliconoides inflatus as a metric for shell calcification using several ... -
Geochemistry of volcanic glass from Mahanadi offshore region, eastern continental margin of India: Constraints on the contribution of latest Toba super-eruption
(Springer, 2024)The tephra layers in multiple sediment cores from the offshore region of the Mahanadi basin in the northern Bay of Bengal were investigated for possible volcanic sources. The glass shards from those tephra layers were ... -
Spatial variability in nitrogen uptake rates and f-ratio in the northern Indian Ocean
(Elsevier, 2024)Inorganic nitrogen is the major limiting nutrient in the northern Indian Ocean. The published and unpublished data of nitrate (NO3?) and ammonium (NH4+) uptake rates and estimated f-ratios (new to total production) for the ... -
Unveiling the faunal diversity in the water column adjacent to two seamounts in the deep Arabian Sea using environmental DNA metabarcoding
(Multidisciplinary Digital Publishing Institute (MDPI), 2024)The diversity of organisms inhabiting deep-sea ecosystems, such as seamounts, has hitherto remained under-studied. In this study, we report on the faunal diversity in the water column adjacent to the summit and periphery ... -
Reinterpretation of marine magnetic anomalies in the Bay of Bengal: Implications for plate tectonics during the mid-cretaceous
(John Wiley & Sons, Ltd, 2024)The breakup of India from Antarctica in the Early Cretaceous and subsequent seafloor spreading in the NW-SE direction initiated the formation of the Bay of Bengal and its conjugate Enderby Basin. Two hypotheses are proposed ... -
Decoupling of carbon burial from productivity in the northeast Indian Ocean
(Elsevier, 2024)The concentration of atmospheric carbon dioxide (CO2) is a crucial climate parameter as it has far-reaching implications on global temperature. The oceans are a significant sink for CO2. Biologically mediated carbon ... -
Enhanced therapeutic efficacy of biogenic nanosilver-conjugated thymol: In vitro and in vivo evaluation against emerging multi-drug resistant microbes
(Elsevier, 2023)Phytochemicals and nanoparticles (NPs) despite having strong antibacterial activity, their limited stability and safety prevent their widespread biomedical and environmental applications. Therefore, the bio-efficacy and ... -
Microbial machinery dealing diverse aromatic compounds: Decoded from pelagic sediment ecogenomics in the gulfs of Kathiawar Peninsula and Arabian Sea
(Elsevier, 2023)Aromatic hydrocarbons are persistent pollutants in aquatic systems as endocrine disruptors, significantly impacting natural ecosystems and human health. Microbes perform as natural bioremediators to remove and regulate ... -
Using multi-spectral remote sensing for flood mapping: A case study in lake Vembanad, India
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Water is an essential natural resource, but increasingly water also forms a threat to the human population, with floods being the most common natural disaster worldwide. Earth Observation has the potential for developing ... -
Global subterranean estuaries modify groundwater nutrient loading to the ocean
(John Wiley & Sons, Ltd, 2024)Terrestrial groundwater travels through subterranean estuaries before reaching the sea. Groundwater-derived nutrients drive coastal water quality, primary production, and eutrophication. We determined how dissolved inorganic ... -
Effects of the pandemic on observing the global ocean
(American Meteorological Society, 2023)The years since 2000 have been a golden age in in situ ocean observing with the proliferation and organization of autonomous platforms such as surface drogued buoys and subsurface Argo profiling floats augmenting ship-based ... -
Plastic litter: A hidden reservoir for antibiotic-resistant pathogens in coastal ecosystems
