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 The published and unpublished data of nitrate (NO3?)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 ... -
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
(Elsevier, 2024)Plastic litter carrying pathogenic bacteria pose serious threats to the health of human and aquatic life. We enumerated the abundance of Escherichia coli and Vibrio species in different types of plastic litter (biomedical, ... -
Comparative study of granulometric and granule trend of pre- and post-tsunami sediments with recent beach sediments from Nagoor to Poompuhar, Tamil Nadu
(Springer, 2024)The December 26, 2004 tsunami waves caused significant destruction that changed geomorphic characteristics in India�s east coast. The article presents a comparative study of granulometric and granule trends of pre-tsunami ... -
Aerosol trace element solubility determined using ultrapure water batch leaching: An intercomparison study of four different leaching protocols
(Copernicus Publications, 2024)Solubility of aerosol trace elements, which determines their bioavailability and reactivity, is operationally defined and strongly depends on the leaching protocol used. Ultrapure water batch leaching is one of the most ... -
Major sources of sinking particulate organic matter in the western Bay of Bengal
(Elsevier, 2024)Impacts of river discharge on coastal ocean processes are multi-dimensional. Studies on sinking particle fluxes, composition and their seasonal variability in coastal oceans are very limited. In this study, we investigated ... -
Insights into the seasonal changes in the taxonomic and functional diversity of bacteria in the eastern Arabian Sea: Shotgun metagenomics approach
(Elsevier, 2024)The eastern Arabian Sea (EAS) is known for its unique oceanographic features such as the seasonal monsoonal winds, upwelling of nutrient-rich waters and a significant increase in primary productivity during the monsoon ... -
Response of coastal phytoplankton to pollution from various sources in the coastal Bay of Bengal
(Springer, 2024)The coastal ocean receives nutrient pollutants from various sources, such as aerosols, municipal sewage, industrial effluents and groundwater discharge, with variable concentrations and stoichiometric ratios. The objective ... -
Daylight driven vertical migration of mesozooplankton in the Arabian sea and the Bay of Bengal
(Elsevier, 2024)Diurnal vertical migration (DVM) of mesozooplankton in the Deep Scattering Layer (DSL) of the Indian seas is poorly studied. This cyclical vertical migration substantially controls the carbon sequestration in the ocean. ... -
Mean wave direction and wave height in the ERA5 reanalysis dataset: Comparison with measured data in the coastal waters of India
