Year-to-year variability of oil pollution along the Eastern Arabian Sea: The impact of COVID-19 imposed lock-downs
(Elsevier, 2022)This study investigated the year-to-year variability in the occurrence, abundance and sources of oil spills in the Eastern Arabian Sea (EAS) using sentinel-1 imagery and identified the potential oil spills vulnerable zones. ... -
Evaluation of a few wave energy converters for the Indian shelf seas based on available wave power
(Elsevier, 2022)The energy resource assessment at a location is crucial for designing wave energy projects. However, there is a divergence in wave energy converter (WEC) design due to diversity in wave climate, energy availability, and ... -
Differential tolerance capacity of intertidal organisms (sponge and zoanthid) to the environmental stresses: Preliminary findings from a rockpool transplantation experiment
(Springer, 2021)Marine intertidal organisms face extreme environmental fluctuations due to tidal cycles. To investigate the impact of environmental changes (high salinity, sea surface temperature, and anthropogenic pollution) on the health ... -
Influence of low-temperature fluids and post-depositional changes in the siliceous-pelagic sediments of the Central Indian Ocean Basin
(Springer, 2021)In this paper, we discuss the possible reasons for the mass disappearance of radiolarians, hiatus in sedimentation, low-temperature alteration of sediments, and formation of palagonite and phillipsites in the Central Indian ... -
Reviews and syntheses: Physical and biogeochemical processes associated with upwelling in the Indian Ocean
(Copernicus GmbH, 2021)The Indian Ocean presents two distinct climate regimes. The north Indian Ocean is dominated by the monsoons, whereas the seasonal reversal is less pronounced in the south. The prevailing wind pattern produces upwelling ... -
Quinolizidine Alkaloids from Marine Organisms: A Perspective on Chemical, Bioactivity and Synthesis
(Bentham Science Publisher, 2021)Marine organisms produce numerous secondary metabolites that exhibit a wide range of biological activities, which have applications in pharmaceutical research. Numerous secondary metabolites have been discovered from various ... -
Quasi-biweekly oscillation in sea level along the western Bay of Bengal
(Elsevier, 2021)This study investigates the variability and sources of Quasi-Biweekly (QB) oscillation (10-20 days) in coastal sea level along the western boundary of the Bay of Bengal (BoB) using tide-gauge data and simulations from a ... -
Molecular Identification and Characterization of Sugar and Peptide Carriers in the Giant Tiger Prawn, Penaeus monodon
(CRC Press, London, 2022)Individuals of the giant tiger prawn Penaeus monodon were collected at a local shrimp farm in Goa. The expression and the tissue distribution of two transport proteins involved, respectively, in sugar and peptide absorption, ... -
Extraterrestrial dust as a source of bioavailable iron contributing to the ocean for driving primary productivity
(Wiley, 2021)Bioavailable Fe is an essential nutrient for phytoplankton that enables the organisms to flourish and draw down atmospheric CO2 thus affecting global climatic conditions. In marine locales, remote from the continents, ... -
Seasonal cycle of zooplankton standing stock inferred from ADCP backscatter measurements in the eastern Arabian Sea
(Elsevier, 2022)We use ADCP (acoustic Doppler current profiler) backscatter, measured during October 2012 to December 2020 at three locations on the continental slope in the eastern Arabian Sea (EAS), to study the seasonal variation in ... -
Characterization of phytoplankton size-structure based productivity, pigment complexes (HPLC/CHEMTAX) and species composition in the Cochin estuary (southwest coast of India): special emphasis on diatoms
(Elsevier, 2021)Seasonal studies on size-fractionated phytoplankton productivity (biomass and primary production), marker pigments, and species composition and abundance were carried out in the Cochin estuary (CE), located on the southwest ... -
Diatom distribution in the Enderby Basin, East Antarctica
(Elsevier, 2021)The distribution of diatom taxa was studied in the Enderby Basin, East Antarctica during the austral summer of 2010. In this study, the influence of freshwater at east of the 55�E was observed due to the melting of sea-ice, ... -
Recently discovered stone anchors of Odisha, east coast of India
(Australasian Institute for Maritime Archaeology, 2020)Anchors are considered as the potsherds of maritime archaeology. Studies of stone anchors provide insight into trade routes, harbours and ports, maritime contacts, transfer of technology. In ancient times, vessels carried ... -
Approach Towards Deep-Sea Mining: Current Status and Future Prospects
(Springer, Cham, 2022)Deep-sea mineral resources within and beyond the national jurisdictions offer several opportunities for exploration and possible exploitation owing to their potential as alternate source of metals such as Ni, Cu, Co, rare ... -
Contrasting Impact of Viral Activity on Prokaryotic Populations in the Coastal and Offshore Regions of the Eastern Arabian Sea
(MDPI, 2022)Viral processes in the coastal and offshore regions of the Eastern Arabian Sea (west coast of India) and their contribution of viral lysis to the organic carbon and nitrogen pool was examined. Water samples were collected ... -
Antioxidant and Antiglycemic Properties of Macroalgae, an Underutilized Blue Economy Bioresource in India
(Springer, 2021)Macroalgae are marine bioresources with a myriad of bioactive potential to treat various chronic diseases such as cancer, obesity, diabetes and coronary heart diseases. Though there is a vast diversity of macroalgal species ... -
The polymers and their additives in particulate plastics: What makes them hazardous to the fauna?
(Elsevier, 2022)Due to the increasing concerns on global ecosystems and human health, the environmental risks posed by microplastics (MPs) and nanoplastics (NPs) have become an important topic of research. Their ecological impacts on ... -
Bioluminescence of green Noctiluca scintillans from the coastal waters of Kochi (southwest coast of India) and in vivo experiments on bioluminescence in response to mechanical stimuli and its diurnal variations
(Taylor & Francis, 2021)A bloom of green Noctiluca scintillans (GNS) was spotted as conspicuous bright blue coloured bioluminescence in the coastal waters of Kochi on 29 May 2019. The intense blue colouration was visible in the inshore waters, ... -
Role of ocean dynamics in the evolution of mixed-layer temperature in the Bay of Bengal during the summer monsoon
(Elsevier, 2021)Earlier studies suggest that the mixed-layer (ML) temperature or sea surface temperature (SST) of the Bay of Bengal during the summer monsoon is determined primarily by air-sea fluxes. We use an oceanic general circulation ... -
