Porewater and solid phase speciation geochemistry of phosphorus in the Western Bay of Bengal: An assessment of depositional pathways
(Elsevier, 2023)In this study, we used a combination of porewater phosphate and solid-phase P speciation to examine the present-day benthic biogeochemical cycling and pathways of phosphorus (P) deposition at four sites in the western Bay ... -
Chemolithoautotrophic denitrification intensifies nitrogen loss in the Eastern Arabian Sea Shelf waters during sulphidic events
(Elsevier, 2023)The Eastern Arabian Sea Shelf i.e. Western Indian Continental Shelf (WICS) – a known biogeochemical hotspot is characterized by monsoonal upwelling, seasonal O2 deficiency, extremely high N2O build-up and sulphidic events. ... -
Marinobacterium lacunae sp. nov. isolated from estuarine sediment
(Springer, 2023)A novel motile bacterium was isolated from a sediment sample collected in Kochi backwaters, Kerala, India. This bacterium is Gram negative, rod shaped, 1.0–1.5 µm wide, and 2.0–3.0 µm long. It was designated as strain ... -
Crustal structure beneath the Alcock Seamount in the Andaman Sea
(Elsevier, 2023)Alcock and Sewell seamounts are important geomorphic features in the Andaman Sea due to their association with the tectonic history of the Sunda subduction zone. Despite the availability of global geophysical data, the ... -
Relationship between coral bleaching and large-scale oscillations in the Lakshadweep archipelago
(Springer, 2023)The coral reef ecosystems in the Lakshadweep Sea are among the least studied due to the dearth of in situ measurements. The objectives of this study were to compare the remote sensing datasets with the available in situ ... -
Phthalate induced hormetic effect reveals susceptibility of gill compared to muscle tissue after depuration in commercially important fish (Etroplus suratensis)
(Elsevier, 2023)Effect of Bis-2ethylhexyl phthalate (DEHP) on commercially important tropical fish pearl spot has not been demonstrated at environmental concentrations along with depuration. The species is estuarine, juvenile and difficult ... -
Longshore currents on a meso-tidal beach of Goa, India - Measurements and improved formulae
(CSIR-NISCPR, New Delhi, 2023)Field experiments in the surfzone were conducted on a meso-tidal beach stretch between Sinquerim and Baga off Goa on India's central west coast. Surfzone waves and currents were measured using an array of seabird wave and ... -
Synthesis of pyrazolo[5,1-a]isoquinolines via C-H/N-H annulation of pyrazoles and alkynes with ruthenium(II) catalysts
(Springer, 2023)A series of pyrazolo[5,1-a]isoquinolines have been synthesized by ruthenium(II)-catalyzed annulation of pyrazole derivatives with alkynes in the presence of Cu(OAc)2‧H2O and AgSbF6 producing pyrazolo[5,1-a]isoquinolines. ... -
A study on microzooplankton community from the coastal waters of eastern Arabian Sea: Emphasis on the dominance of heterotrophic dinoflagellates
(Springer, 2023)We studied the community composition of microzooplankton (MZP) from the surface waters off Candolim, Goa. The MZP communities were examined for the year 2013, covering different seasons and four stations (Near-shore: G3 & ... -
Nature and hydrocarbon potential of organic matter in offshore Mahanadi Basin, east coast of India
(Springer, 2023)Evaluating the hydrocarbon-generating potential of buried organic matter in marine sediments is critical in offshore oil/gas exploration. Organic matter sources, total organic matter content (TOC), and maturity state play ... -
Lithospheric architecture beneath the Amsterdam-St. Paul plateau, Southern Indian Ocean using the integrated gravity, magnetic and seismological study
(Elsevier, 2023)Evolution of the Amsterdam-St. Paul (ASP) plateau is debated as a consequence of the Kerguelen mantle plume interaction with the South-East Indian Ridge (SEIR) or related with a weaker ASP plume origin. We performed an ... -
Geochemistry of metals in grain size fractionated sediments from estuarine and coastal regions along Mumbai: A baseline information
(CSIR-NISCPR, New Delhi, 2023)Differential metal accumulation in fractionated sediments within highly urbanized land-sea ecosystems is significant, often due to an imbalance between sluggish hydrodynamics and over dumping of contaminants. Here, an ... -
Biodegradation of mixed polycyclic aromatic hydrocarbons by Pseudomonas sp. isolated from estuarine sediment
(Taylor and Francis, 2023)Polycyclic aromatic hydrocarbons (PAHs) are released into the environment via several natural and anthropogenic sources leading to long-term consequences that severely affect the environment, ecosystem, human and animal ... -
Analysis of recent airborne gravity and magnetic data for the interpretation of basement structures underneath the south-western Benue trough using source edge detector filters
(Springer, 2023)We present the detail basement and trends of geological structures associated with the Mesozoic-Cenozoic volcanism in the south-western region of the Nigerian Benue trough using recent gravity and magnetic anomalies of the ... -
Recent global insight into mitigation of plastic pollutants, sustainable biodegradable alternatives, and recycling strategies
(Springer, 2023)Plastics are organic polymers mainly derived from petrochemicals which can be flexibly molded into different shapes. Due to the many benefits of petroleum plastics, including their low cost, high durability, resistance to ... -
Environmental and human facets of the waterweed proliferation in a vast tropical Ramsar wetland - Vembanad lake system
(Springer, 2023)The Vembanad Lake and its associated low-lying areas and network of canals (hereafter VBL) form the major part of India’s second-largest Ramsar wetland (1512 km2) located in Kerala State along India’s southwest coast. The ... -
Geochemical tracing of synoptic scale modern dust transport over the Northeast Arabian Sea during the southwest monsoon
(Elsevier, 2023)During the Southwest monsoon (SWM), aeolian dust is mainly supplied via wet deposition over the northeast Arabian Sea (NEAS). To understand their impact on the biogeochemistry of the Arabian Sea, it is important to identify ... -
Assessing seasonal nitrogen transformations in the Godavari estuary, India
(Elsevier, 2023)Indian estuaries are hypothesized to export a significant amount of nitrogen nutrients to the coastal waters due to the high use of fertilizers. To examine the possible sources of nitrogen nutrients and their modifications ... -
Role of inter-annual variability in the magnitude of river discharge on CO2 fluxes in the Godavari tidal river zone, India
(Elsevier, 2023)Variations in the magnitude of river discharge may alter pH, pCO2 of surface water, and flux of CO2 to the atmosphere in the Tidal River Zone (TRZ). To test this hypothesis, a nearly decade-long time-series data of salinity, ... -
