Distribution and bioaccumulation status of polycyclic aromatic hydrocarbons (PAHs) in Veraval coastal waters using copepods as bio-indicators
(Springer, 2024)The study investigates the pollution characteristics of 16 priority PAHs, accumulated in copepods from a major fishing harbour and its adjacent coastal waters of Veraval, west coast of India. The total PAH accumulation is ... -
Response of inner shelf benthic foraminiferal community to different concentrations of dissolved oxygen under laboratory culture experiment
(SAGE Publications, New Delhi, India, 2024)Dissolved oxygen, a vital parameter for a majority of marine organisms, may decline in the near future due to anthropogenic eutrophication in coastal waters. The effect of depleting dissolved oxygen on the marine benthic ... -
First report of the rare tintinnid genus Stelidiella Kofoid and Campbell 1929 in the Indian Ocean
(Oxford University Press, 2024)This study provides detailed information on the morphometry and distribution of some rare tintinnids species found in the Indian Ocean. The morphological features (scabbard-shaped with a fenestrated collar) reported here ... -
Assessment of aerosol-cloud interactions over the Northern Indian Ocean
(Elsevier, 2024)The interaction between aerosol and cloud causes one of the largest uncertainties in external forcing to our climate system, highlighting the importance of additional extensive research on aerosol - cloud interaction (ACI). ... -
BODIPY-cucurbituril complexes: Supramolecular approach toward improvement of photodynamic activity
(Royal Society of Chemistry, 2024)The host-guest interaction of cucurbit[7]uril with lipophilic BODIPYs decreases their aggregation in water and improves the photophysical properties. Phototoxicity of the complex with one CB[7] moiety increased up to seven ... -
Do microplastics accumulate in penguin internal organs? Evidence from Svenner island, Antarctica
(Elsevier, 2024)The prevalence of microplastics (MPs, <5 mm) in natural environments presents a formidable global environmental threat MPs can be found from the Arctic to Antarctica, including glaciers. Despite their widespread distribution, ... -
Copepod community in the coastal waters off Kochi (India) signify the enhanced estuarine flushing during the Southwest Monsoon
(Elsevier, 2024)Even though many studies refer to copepods as potential indicators of hydrographical settings and/or water masses, focused studies on this aspect are very scarce in Indian waters. Hence, this study assesses the hydrography ... -
Dominant contribution of atmospheric nonlinearities to ENSO asymmetry and extreme El Nino events
(Nature Publishing Group, 2024)Extreme El Nino events have outsized impacts and strongly contribute to the El Nino Southern Oscillation (ENSO) warm/cold phase asymmetries. There is currently no consensus on the respective importance of oceanic and ... -
Resilience-based assessment of shallow water patchy reefs in Palk Bay of South East Coast of India
(Springer, 2024)The health of coral reefs in Palk Bay has been influenced by several natural and anthropogenic stressors over the last four decades. This study assessed the resilience potential of Scleractinian corals and their associated ... -
Surface ocean-lower atmospheric processes in the Indian Ocean: Current understanding, knowledge gaps, and future directions
(University of California Press, 2024)Our understanding of surface ocean and lower atmosphere processes in the Indian Ocean (IO) region shows significant knowledge gaps mainly due to the paucity of observational studies. The IO basin is bordered by landmasses ... -
Morphotectonic characteristics of the Andaman volcanic arc and its adjoining regions, Andaman Sea
(Springer, 2024)The oblique subduction of the Indian Plate beneath the Sunda Plate has resulted in the formation of diverse morphotectonic structures and major changes to the seafloor topography in the Andaman Sea, northeastern Indian ... -
A new climatology of depth of nitracline in the Bay of Bengal for improving model simulations
(John Wiley & Sons, Ltd, 2024)The dissolved nitrate is one of the major essential nutrients for primary production in the tropical ocean and it is brought to the surface though mixing. The depth of nitracline determines how much of nitrate enters to ... -
Isotopic evidence of denitrified nitrate in groundwater beneath intensive agriculture and exchange with estuary (Godavari, India)
(American Chemical Society, 2024)Nitrate is accumulated in the groundwater, modified through nitrification/denitrification, and exchanged with coastal/estuarine water bodies. To examine the sources and modifications of nitrate, the concentrations and ... -
Recent toolset of metagenomics for taxonomical and functional annotation of marine associated viruses: A review
(Elsevier, 2024)The most prevalent biological species on earth are viruses, the majority of which infect bacteria. Less than 1 % of microbial hosts have been cultured, making it difficult to identify and measure the dynamics of viral ... -
Genome and compound analysis of sioxanthin-producing marine Actinobacterium Micromonospora sp. nov. Strain sh-82 isolated from sponge Scopalina hapalia
(Springer, 2024)Pigments and other secondary metabolites originating from marine microbes have been a promising natural colorants and drugs for multifaceted applications. However, marine actinobacteria producing such natural molecules are ... -
Lead removal efficiency and bioflocculation potential of bacteria isolated from water and sediments of a tropical creek of India
(Springer, 2024)For the first time, five lead-resistant bacteria were isolated from the marine water and sediments of Versova Creek, Mumbai, India, and analysed for their bioflocculation-assisted bioremediation potential. Based on 16 S ... -
Metagenomic insights into bacterial dynamics and niche partitioning in response to varying oxygen gradients in the Arabian Sea oxygen minimum zone (OMZ)
(Elsevier, 2024)This study investigates the impact of oxygen gradients on bacterial diversity and community composition within the Arabian Sea oxygen minimum zone (OMZ), providing insight into their ecology in this unique environment. ... -
Dissolved organic carbon (DOC) and labile organic compounds spatial and temporal variations in coastal Indian groundwater: Their bioavailability and transfer to neighboring coastal waters of India
(Springer, 2024)Submarine groundwater drainage (SGD) changes the elemental composition of the neighboring coastal ocean and impacts the biogeochemical cycles. To examine the seasonal and spatial variability in dissolved organic carbon ... -
Temporal temperature shifts govern the population succession of picoeukaryotes and picocyanobacteria in a coastal ecosystem
(Elsevier, 2024)Picophytoplankton are vital components of the marine microbial food web. Being the smallest in the phytoplankton group, their short life cycles make them excellent bioindicators of environmental conditions. Given this, an ... -
