A comparison of bacterial communities from OMZ sediments in the Arabian Sea and the Bay of Bengal reveals major differences in nitrogen turnover and carbon recycling potential
(Taylor and Francis, 2020)
The Northern Indian Ocean hosts two Oxygen Minimum Zones (OMZ), one in the Arabian Sea and the other in the Bay of Bengal. 16S rRNA gene amplicon sequencing was used to understand the total bacterial diversity in, the ...
Formation and weathering assessment of oil-suspended sediment aggregates through a laboratory investigation
(Springer, 2021)
Formation of oil-suspended sediment aggregates (OSAs) is believed to be one of the natural cleaning processes in the marine environment. In this study, we have investigated the formation processes of OSAs under different ...
Dynamics of Vibrio cholerae in a Typical Tropical Lake and Estuarine System: Potential of Remote Sensing for Risk Mapping
(MDPI AG, 2021)
Vibrio cholerae, the bacterium responsible for the disease cholera, is a naturally-occurring bacterium, commonly found in many natural tropical water bodies. In the context of the U.N. Sustainable Development Goals (SDG) ...
Genetic variability in the natural populations of Carinotetraodon travancoricus revealed using itochondrial COI sequences
(John Wiley and Sons, Ltd, 2021)
Carinotetraodon travancoricus or Malabar puffer fish is an endemic species described from rivers originating from the Western Ghats in South India. This species is captured extensively as an aquarium fish and is having ...
Strike-slip seismicity at the Andaman-Sumatra Subduction Zone: Role of the fracture zones and age of the subducting lithosphere
(Elsevier, 2021)
A better comprehension of the shallow strike-slip seismicity along the Sunda Trench is achieved by superimposing the Wharton basin fracture zones, magnetic isochrones, and focal mechanisms to the geometry of the subducting ...
Molluscan Diversity Influenced by Mangrove Habitat in the Khors of Qatar
(Springer, 2021)
The Exclusive Economic Zone (EEZ) of Qatar is a rapidly developing region within the Arabian Gulf, where monitoring of changes in benthic biodiversity and its functioning is needed. The influence of mangroves and seasonality ...
Possible Linkages between Microseisms in the Andaman?Nicobar Region and Swells in the South Indian Ocean
(Seismological Society of America, 2021)
Microseism source characterization and its genesis play a key role in linking microseism records to prevailing atmospheric and oceanic conditions. In the present study, we analyzed the spatial and temporal distribution of ...
Biophysical responses to tropical cyclone Hudhud over the Bay of Bengal
(Taylor and Francis Ltd., 2021)
Cyclone Hudhud originated in the Andaman Sea on 6 October 2014. Later, it intensified into a cyclonic storm on 8 October and eventually made landfall at Visakhapatnam on 12 October as a very severe cyclonic storm. It was ...
Concentration of Trace Metals and Biochemical Alterations in Various Species of Fishes along the West Coast of India
(Korea Ocean Research and Development Institute, 2021)
This study seeks to evaluate levels of seven trace metals (Cr, Mn, Fe, Cu, Zn, Pb and Hg) and biochemical (proteins, lipids and carbohydrates) alterations in muscle tissue of 27 commercially important fish species collected ...
Seasonal variations in viral distribution, dynamics, and viral-mediated host mortality in the Arabian Sea
(Springer, 2021)
Viruses are key players in the marine ecosystem. It is critical to study specific viral processes and their inter-relationship with various biotic and abiotic variables to quantify their impact on the marine environment. ...
