Distribution, contamination status and bioavailability of trace metals in surface sediments along the southwest coast of India
(Elsevier, 2021)
This study investigates the influence of upwelling induced seasonal hypoxia in the sediment-water interface on the distribution, bioavailability and geochemical partitioning of selected trace metals in surficial sediments ...
Phytoplankton characterisation in the Alappuzha mud banks during the pre-/post phases of a red-tide, Prorocentrum shikokuense Hada
(Elsevier, 2020)
The short-term changes in hydrochemical and phytoplankton characteristics occurring in the Alappuzha mud bank (AMB) region, located on the southwest coast of India, were monitored in association with a red-tide event caused ...
Prevalence of obligate and facultative anaerobic bacteria in the mudbank along the southwest coast of India
(Elsevier, 2021)
Mudbanks along the southwest coast of India are exposed to upwelled hypoxic waters and higher concentrations of methane during summer-monsoon.We report the phylogenetic composition of obligate and facultative anaerobic ...
Trace metal distribution in the sediment cores of mangrove ecosystems along northern Kerala coast, south-west coast of India
(Elsevier Ltd, 2020)
Core sediment samples were collected from five mangrove ecosystems along northern Kerala coast (Kunjimangalam: S1, Pazhayangadi: S2, Pappinissery: S3, Thalassery: S4, and Kadalundi: S5) to assess the status of heavy metal ...
Triterpenoids and fatty alcohols as indicators of mangrove derived organic matter in Northern Kerala Coast, India
(Taylor & Francis, 2022)
Triterpenoids and fatty alcohols were identified from the sediments of five mangrove ecosystems (Kunjimangalam, Pazhayangadi, Pappinissery, Thalassery, and Kadalundi) in the northern Kerala coast, India, to illustrate the ...
Distribution and sources of fatty acids in surface sediments of mangrove ecosystems in the Northern Kerala Coast, India
(Taylor & Francis, 2023)
Fatty acids and bulk geochemical proxies were employed to understand the sources and transformation of sedimentary organic matter from surface sediments of major five mangrove systems in the northern Kerala coast. Texture, ...
Distribution and antibiotic resistance of vibrio population in an urbanized tropical lake-the Vembanad-in the southwest coast of India
(Springer, 2023)
Among the diverse Vibrio spp. autochthonous to coastal ecosystems, V. cholerae, V. fluvialis, V. vulnificus and V. parahaemolyticus are pathogenic to humans. Increasing sea-surface temperature, sea-level rise and water-related ...
Dynamics of nitrous oxide and methane in the southeastern Arabian Sea
(Elsevier, 2024)
This study examined the factors controlling the intra- and inter-seasonal variations of dissolved methane (CH4) and nitrous oxide (N2O) in the southeastern Arabian Sea (SEAS). Time-series measurements of CH4, N2O and allied ...

(Frontiers Media, 2023)
This is an Editorial of the special issue of Frontiers in Marine Science on the Topic of recent developments in oxygen minimum zones biogeochemistry. This Research Topic presents 14 original research articles with the goal ...
Occurrence, sources and risk assessment of polycyclic aromatic hydrocarbons in the coral reef waters of the Lakshadweep Archipelago, Arabian Sea
(Elsevier, 2024)
The compound effects of anthropogenic disturbances on global and local scales threaten coral reef ecosystems of the Arabian Sea. The impacts of organic pollutants on the coral reefs and associated organisms have received ...
