Reconstruction of Holocene relative sea-level from beach ridges of the central west coast of India using GPR and OSL dating
(Elsevier, 2023)The Holocene sea-level and associated shoreline regression of beach ridges in the central west coast of India have been reconstructed based on internal sedimentary architecture and luminescence chronology. For this purpose, ... -
Implications of single-stage deep learning networks in real-time zooplankton identification
(Current Science Association, IAS, 2023)Zooplankton are key ecological components of the marine food web. Currently, laboratory-based methods of zoo-plankton identification are manual, time-consuming, prone to human error and require expert taxonomists. Therefore, ... -
The consequences of reduced anthropogenic activities during the COVID-19 pandemic on microplastic abundance in a tropical estuarine region: Goa, India
(Elsevier, 2024)Plastic pollution is pervasive, as it has infiltrated every corner of the planet and the COVID-19 pandemic has caused a depletion in the production, consumption, and disposal of plastics. To find out the effect of the ... -
Identification and physico-chemical characterization of microplastics in marine aerosols over the northeast Arabian Sea
(Elsevier, 2024)Microplastics (MPs) in the atmosphere can undergo long-range transport from emission regions to pristine terrestrial and oceanic ecosystems. Due to their inherent toxic and hazardous characteristics, MPs pose serious risks ... -
Editorial: Recent developments in oxygen minimum zones biogeochemistry
(Frontiers Media, 2023)This is an Editorial of the special issue of Frontiers in Marine Science on the Topic of recent developments in oxygen minimum zones biogeochemistry. This Research Topic presents 14 original research articles with the goal ... -
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 ... -
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 & ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
