Coastal vegetation and estuaries are collectively a greenhouse gas sink
(Springer Nature, 2023)
Coastal ecosystems release or absorb carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), but the net effects of these ecosystems on the radiative balance remain unknown. We compiled a dataset of observations from ...
Morphotectonics of the Raman-Panikkar-Wadia seamount chain in the Laxmi Basin, Eastern Arabian Sea
(Elsevier, 2024)
The Laxmi Basin, which is a deep ocean basin situating adjoining to the northwestern continental margin of India, contains a linear seamount chain consisting of the Raman Seamount, Panikkar Seamount and the Wadia Guyot, ...
A comprehensive assessment of macro and microplastics from rivers Ganga and Yamuna: Unveiling the seasonal, spatial and risk factors
(Elsevier, 2024)
There have been growing apprehensions and concerns regarding the increasing presence of plastic pollutants in the holiest river of India, the Ganga, and its major tributary, Yamuna. In response to this issue, the current ...
Chemical compositions of Fe-rich relict olivines from cosmic spherules, understanding their links with ordinary and carbonaceous chondrites
(John Wiley & Sons, Ltd, 2024)
Fe-rich relict olivine grains are found in a small percentage of cosmic spherules, which are studied here to determine the nature of their precursors. We examined 128 Fe-rich relict olivine grains with Fa >10 mol% from 53 ...
Massive influence of Himalayan source on sedimentation along northern Indian peninsular basin
(Elsevier, 2023)
A 39 m long sediment core (MD161-19) spanning 320 ka, collected from the intermediate water depths of (1480 m) of Mahanadi offshore was subjected to provenance analyses using Sr and Nd isotope systematics. The Sr–Nd isotope ...
Mid-Pleistocene transition altered upper water column structure in the Bay of Bengal
(Elsevier, 2023)
The unique water column structure and seasonal change in the hydrodynamics make the Bay of Bengal an interesting area to understand the effect of monsoon on the water column stratification. We have reconstructed a 1.45 Myr ...
Linking genetic lineages of giant freshwater prawn Macrobrachium rosenbergii to their global populations
(Springer, 2024)
Globally, the giant freshwater prawn Macrobrachium rosenbergii is considered as a commercially important aquaculture species. Genetically, this species is differentiated into western, central and eastern populations. ...
Endosymbiotic Symbiodinium clades occurrence and influence on coral growth and resilience during stress
(Springer, 2022)
The endosymbionts of Symbiodiniaceae members establish an obligate relationship with most of the reef-building corals.Photosynthates of Symbiodiniaceae symbionts provide the maximum energy requirements of the host coral.Apart ...
Antimicrobial activity of coral-associated beneficial bacteria against coral disease-causing microbial pathogens
(John Wiley & Sons, Ltd, 2024)
Microbial infection of immune-compromised corals influences disease severity, resulting in coral mortality. However, coral-associated beneficial bacteria are known to produce antimicrobial compounds that prevent the growth ...
Fungal diversity associated with Goa�s tarballs: Insights from ITS region amplicon sequencing
(Elsevier, 2024)
This study explores the fungal diversity associated with tarballs, weathered crude oil deposits, on Goa�s tourist beaches. Despite tarball pollution being a longstanding issue in Goa state in India, comprehensive studies ...
