Half-sandwich iridium(III) and rhodium(III) complexes: Synthesis, characterization and antifouling properties
(Taylor & Francis, 2023)The reaction of [(η5-C5Me5)MCl2]2 [M = Ir (1) or Rh (2)] with thiazole ligands (L) at room temperature [L = atz; 2-acetamidothiazole (3) or catz; 5-chloro-2-acetamidothiazole (4)] afforded iridium(III) and rhodium(III) ... -
Link of the short-term temporal trends of Sr and Nd isotopic composition of aeolian dust over the Arabian Sea with the source emissions
(Elsevier, 2023)Aeolian transport of continental dust from the Middle East and South Asia to the Arabian Sea (AS) is an important route for delivering key trace metals and nutrients. Despite being surrounded by several deserts, it is not ... -
Diatom community dynamics in a tropical brackish coastal ecosystem from an ecological and biogeochemical perspective: A size-fractionated approach
(Elsevier, 2023)Diatoms are a major, ubiquitous photosynthetic group representing most aquatic ecosystem’s microalgal communities. The species composition encompasses a wide range of cell sizes. Although cell size is vital in aquatic ... -
Mid-Pleistocene transition altered upper water column structure in the Bay of Bengal
(Elsevier, 2023)The unique water column structure and seasonal change in the hydrodynamics make the Bay of Bengal an interesting area to understand the effect of monsoon on the water column stratification. We have reconstructed a 1.45 Myr ... -
Massive influence of Himalayan source on sedimentation along northern Indian peninsular basin
(Elsevier, 2023)A 39 m long sediment core (MD161-19) spanning 320 ka, collected from the intermediate water depths of (1480 m) of Mahanadi offshore was subjected to provenance analyses using Sr and Nd isotope systematics. The Sr–Nd isotope ... -
More than half of emitted black carbon is missing in marine sediments
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)Marine sediments are the ultimate reservoir for black carbon (BC) preservation, and BC burial in sediment/soils is an efficient method for carbon sequestration to mitigate CO2 emissions. A portion of soil charcoal and ... -
Standardization of micro-FTIR methods and applicability for the detection and identification of microplastics in environmental matrices
(Elsevier, 2023)The ubiquity of microplastics (MPs) in the various environment is of increasing concern. Although micro Fourier Transform Infrared Spectroscopy (μ-FTIR) represents an ideal method for the detection of MPs, this technique ... -
Stakeholder alliances are essential to reduce the scourge of plastic pollution
(Springer Nature, 2023)Progress to reduce plastic pollution has been painfully slow and the consequent damage to the natural environment and to human health is likely to increase further. This has been because the views and ways of working of ... -
Air-Sea Fluxes of CO2 in the Indian Ocean Between 1985 and 2018: A Synthesis Based on Observation-Based Surface CO2, Hindcast and Atmospheric Inversion Models
(Wiley-AGU, 2023)The Indian Ocean significantly influences the global carbon cycle but it is one of the undersampled regions with reference to surface ocean pCO2. As a part of the Regional Carbon Cycle Assessment and Processes-2 (RECCAP2) ... -
Preliminary observations on the coral reef communities in Angria Bank, an isolated carbonate bank in the Northern Indian Ocean
(Elsevier, 2023)Submerged carbonate banks are of significant geological and biological importance and relatively little is known about the biodiversity of these deeper and less accessible habitats. This study provides pilot information ... -
Role of physical processes in regulating the biological responses in the Eastern Arabian Sea during the late southwest monsoon
(Elsevier, 2023)Understanding physical properties and associated biological responses in the marine ecosystem is critical for fisheries and assessing the ocean’s role in determining the fate of anthropogenic carbon dioxide emissions. This ... -
Seasonal variation and spatial distribution of microplastic pellets and their associated contaminants along the central east coast of India
(Springer, 2023)Microplastic pellets (MPPs) are one of the significant sources of plastic pollution on shorelines worldwide. In this study, for the first time, we have examined the occurrence of MPPs and their spatial and seasonal ... -
Luminescent quantum dots: Synthesis, optical properties, bioimaging and toxicity
(Elsevier, 2023)Luminescent nanomaterials such as semiconductor nanocrystals (NCs) and quantum dots (QDs) attract much attention to optical detectors, LEDs, photovoltaics, displays, biosensing, and bioimaging. These materials include metal ... -
Long-term changes in Nutrient Concentration and Fluxes from the Godavari Estuary: Role of River Discharge and Fertilizer Inputs
(Springer, 2023)The discharge from the Indian peninsular rivers is strongly controlled by the intensity of monsoonal rainfall, which is strongly influenced by atmospheric extreme events, such as El Niño, La Niña, and Indian Ocean Dipole ... -
Impact of ocean warming on net primary production in the northern Indian Ocean: role of aerosols and freshening of surface ocean
(Springer, 2023)Warming due to climate change stratifies the upper ocean and reduces nutrient input to the photic zone resulting in a decline in net primary production (NPP). On the other hand, climate change increases both anthropogenic ... -
Recurrence of Gonyaulax polygramma bloom in the southeastern Arabian Sea
(Springer, 2023)Gonyaulax polygramma, a bloom-forming dinoflagellate, has been repeatedly observed along the southeastern Arabian Sea in recent years. During our study in October 2021, a patch of reddish-brown water was observed in the ... -
Responses of Phytoplankton Benthic Propagules to Macronutrient Enrichment and Varying Light Intensities: Elucidation from Monsoon-Influenced Mandovi and Zuari Riverine System
(Springer, 2023)The ecological importance of phytoplankton-benthic-propagules (PBP) from coastal sediments, except tropical monsoon-influenced rivers and estuaries, is well documented. PBP in such systems is often transported from upstream ... -
Coastal vegetation and estuaries are collectively a greenhouse gas sink
(Springer Nature, 2023)Coastal ecosystems release or absorb carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), but the net effects of these ecosystems on the radiative balance remain unknown. We compiled a dataset of observations from ... -
