In situ measurements of bioluminescence response of Gonyaulax spinifera to various mechanical stimuli
(Springer, 2021)A conspicuous bioluminescence during nighttime was reported in an aquaculture farm in the Cochin estuary due to Gonyaulax spinifera bloom on March 20, 2020. In situ measurements on bioluminescence was carried out during ... -
Meta-analysis cum machine learning approaches address the structure and biogeochemical potential of marine copepod associated bacteriobiomes
(Springer-Nature, 2021)Copepods are the dominant members of the zooplankton community and the most abundant form of life. It is imperative to obtain insights into the copepod-associated bacteriobiomes (CAB) in order to identify specific bacterial ... -

(Current Science Association, IAS, 2021)Numerous stone and iron anchors of various shapes and sizes have been brought to light during the maritime archaeological explorations along the Indian littoral. And anchors are proxies to maritime archaeological studies. ... -
Particulate organic matter dynamics and its isotopic signatures (?13CPOC and ?15NPN) in relation to physical forcing in the central Arabian Sea during SW monsoon (2017-2018)
(Elsevier, 2021)Monsoonal changes in particulate organic matter (POM) and its isotopic signatures (?13CPOC and ?15NPN) were studied (Aug 2017 and 2018) in the central Arabian Sea (21-11�N 64�E) . A low-level atmospheric jet (Findlater ... -
Diagenesis of Magnetic Minerals in Active/Relict Methane Seep: Constraints From Rock Magnetism and Mineralogical Records From Bay of Bengal
(Frontiers Media�, 2021)In this study, we conducted a comprehensive investigation of rock magnetic, mineralogical, and sedimentological records of sediment cores supplemented by a high resolution seismic data to elucidate the controls of structural ... -
Dry-deposition of inorganic and organic nitrogen aerosols to the Arabian Sea: Sources, transport and biogeochemical significance in surface waters
(Elsevier, 2021)Air-to-sea deposition of water-soluble total nitrogen (WSTN) can influence the primary productivity in the coastal oceans. Here, we assessed the concentrations of aerosol inorganic (WSIN: NH4+ + NO3?) and WSTN over the ... -
Ambient air characteristics of biogenic volatile organic compounds at a tropical evergreen forest site in Central Western Ghats of India
(Springer Science and Business Media B.V., 2021)Non-methane volatile organic compounds (NMVOCs) play key roles in local and regional atmospheric chemistry as precursors for the production of ozone and secondary organic aerosols. Ambient air C2-C5 NMVOCs were measured ... -
Impact of human-altered hydrographical setting on the Copepod community structure in an extensive tropical estuary along the southwest coast of India
(Elsevier, 2021)This study presents how human-altered hydrographical settings (flow restrictions) impacts the natural distribution and community structure of copepods in the Kochi Backwaters (KBW), the largest monsoonal estuary along the ... -
Influence of anthropogenic activities on the spatial distribution of heterotrophic, indicator and pathogenic bacteria around Andaman and Nicobar Islands
(Elsevier, 2021)To examine the influence of anthropogenic activities on the marine ecosystem around the Andaman and Nicobar Islands, a study was conducted to investigate the abundance of heterotrophic, indicator and pathogenic bacteria ... -
Exploring novel functionality for efficient extraction of UO22+ and Th4+in ionic liquid: Mechanism, speciation, selectivity, stability and stripping
(Elsevier, 2021)Novel ligand functionality, 5-bromo-N1, N3-bis(4,6-dimethylpyridin-2-yl)isophthalamide, was explored for highly efficient and selective separation of UO22+ and Th4+ in pyridinium based ionic liquid. The comprehensive ... -
Last 10000 years Variation in the Intensity of OMZ-Core Reconstructed from Sediment of the Eastern Arabian Sea
(Springer, 2021)The Arabian Sea Oxygen Minimum Zone (OMZ) is one of the most intense of the world ocean OMZs witnessing denitrification, hence, has implications to global climate. In order to understand the Holocene variations in the OMZ ... -
Wave height distribution in unsaturated surf zones
(Elsevier, 2021)This paper addresses the performance of different wave height distributions in the surf zone on natural beaches on the central west coast of India. The surfzone water level data for different surf zones were analyzed using ... -
Differential Symbiodiniaceae Association With Coral and Coral-Eroding Sponge in a Bleaching Impacted Marginal Coral Reef Environment
(Frontiers, 2021)Marginal reefs are known for severe stress-inducible perturbations such as high sedimentation, eutrophication, ocean warming, and acidification from anthropogenic climate change. The corals striving in such stressful ... -
Carbon Dioxide Concentration Mechanisms in Natural Populations of Marine Diatoms: Insights From Tara Oceans
(Frontiers Media S.A., 2021)Marine diatoms, the most successful photoautotrophs in the ocean, efficiently sequester a significant part of atmospheric CO2 to the ocean interior through their participation in the biological carbon pump. However, it is ... -
Geochemistry of aerodynamically distorted Australasian microtektites: Implications for ejecta on Mars and Venus
(Springer, 2021)We report microtektites recovered from a large area of the deep seafloor (Central Indian Ocean) that appear to have undergone aerodynamic distortion during re-entry into the atmosphere. Considering the geographic locations, ... -
