Intrinsic versus wind-forced great whirl non-seasonal variability
(John Wiley & Sons, Ltd, 2024)
The Great Whirl (GW) is a quasi-permanent anticyclonic eddy that appears every summer monsoon offshore of the Somalia upwelling. The annual cycle of the GW is well described, but deviations from its mean seasonal cycle ...
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 ...
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 ...
