Major sources of sinking particulate organic matter in the western Bay of Bengal
(Elsevier, 2024)Impacts of river discharge on coastal ocean processes are multi-dimensional. Studies on sinking particle fluxes, composition and their seasonal variability in coastal oceans are very limited. In this study, we investigated ... -
Insights into the seasonal changes in the taxonomic and functional diversity of bacteria in the eastern Arabian Sea: Shotgun metagenomics approach
(Elsevier, 2024)The eastern Arabian Sea (EAS) is known for its unique oceanographic features such as the seasonal monsoonal winds, upwelling of nutrient-rich waters and a significant increase in primary productivity during the monsoon ... -
Response of coastal phytoplankton to pollution from various sources in the coastal Bay of Bengal
(Springer, 2024)The coastal ocean receives nutrient pollutants from various sources, such as aerosols, municipal sewage, industrial effluents and groundwater discharge, with variable concentrations and stoichiometric ratios. The objective ... -
Daylight driven vertical migration of mesozooplankton in the Arabian sea and the Bay of Bengal
(Elsevier, 2024)Diurnal vertical migration (DVM) of mesozooplankton in the Deep Scattering Layer (DSL) of the Indian seas is poorly studied. This cyclical vertical migration substantially controls the carbon sequestration in the ocean. ... -
Mean wave direction and wave height in the ERA5 reanalysis dataset: Comparison with measured data in the coastal waters of India
(Elsevier, 2024)Information on wave direction and height is an important input to the coastal engineers. The availability of measured data at every location in the ocean makes maritime operations smoother. However, the practical impossibility ... -
Global oceanic diazotroph database version 2 and elevated estimate of global oceanic N2 fixation
(Copernicus Publications, 2023)Marine diazotrophs convert dinitrogen (N2) gas into bioavailable nitrogen (N), supporting life in the global ocean. In 2012, the first version of the global oceanic diazotroph database (version 1) was published. Here, we ... -
Evidence of deep subsurface carbon-sulfur geochemistry in a sediment core from the eastern Arabian Sea
(Springer, 2024)Deep biospheric anaerobic microbial sulfate reduction and oxidative sulfur cycling have been studied in long sediment cores mainly acquired as part of IODP explorations. The most remarkable observation in many of these ... -
Role of phytoplankton composition on exudation of dissolved organic carbon in the Bay of Bengal
(Elsevier, 2024)Phytoplankton in the marine environment exudates part of the primary production as dissolved organic carbon (DOC) into the surrounding waters. The rate of exudation of DOC is depended on the hydrographic condition, nutrient ... -
Effect of coastal hypoxia on bacterial diversity as elucidated through 16S rRNA amplicon sequencing
(Frontiers Media SA, 2024)The formation of oxygen-depleted zones in the bottom waters is one of the most widespread phenomena in coastal areas. Upwelling episodes along India�s west coast due to the southwest monsoon increase biological productivity, ... -
Effect of habitat attributes on the abundance of Sargassum�s epifauna and the feeding habit of an amphipod epifauna from the coast of Western India
(CSIR-National Institute of Science Communication and Policy Research, CSIR-NISCPR, 2023)The Sargassum bed along the rocky intertidal region is highly productive and serves as a habitat for numerous associated species. In this study, the effect of habitat attributes (algal morphology) on the abundance and ... -
Directional characteristics of waves in the nearshore waters of the eastern Arabian Sea
(Elsevier, 2024)Directional characteristics of the waves at a coastal location in the eastern Arabian Sea are studied based on the data measured from April 2008 to December 2020. The multiple-scale variations; daily, monthly, intraseasonal, ... -
Revisit of ballast hypothesis in the Bay of Bengal
(Elsevier, 2024)The ballast hypothesis involving rapid sinking of organic carbon in association with riverine mineral particles is proposed in the Bay of Bengal (BoB) in 1991. The ballast hypothesis was used intensively to explain several ... -
Sea-surface pCO2 maps for the Bay of Bengal based on advanced machine learning algorithms
(Nature Publishing Group, 2024)Lack of sufficient observations has been an impediment for understanding the spatial and temporal variability of sea-surface pCO2 for the Bay of Bengal (BoB). The limited number of observations into existing machine learning ... -
Understanding heavy metal toxicity: Implications on human health, marine ecosystems and bioremediation strategies
(Elsevier, 2024)Heavy metals are constituents of the natural environment and are of great importance to both natural and artificial processes. But in recent times the indiscriminate use of heavy metals especially for human purposes has ... -
A multi-proxy lacustrine sedimentary record of sub-decadal to decadal scale variability of monsoon during the late Holocene in southern India
(Elsevier, 2024)The present study is aimed at understanding the sub-decadal to decadal scale variability of rainfall in southern India based on a sedimentary record (dated using AMS 14C, 210Pb, 137Cs methods) from Madagadakere lake (MK) ... -
Environmental and ecological risk of microplastics in the surface waters and gastrointestinal tract of skipjack tuna (Katsuwonus pelamis) around the Lakshadweep Islands, India
(Springer, 2024)The presence of microplastics (MPs) in marine ecosystems is widespread and extensive. They have even reached the deepest parts of the ocean and polar regions. The number of articles on plastic pollution has increased in ... -
Seasonal enhancement of phytoplankton biomass in the southern tropical Indian Ocean: Significance of meteorological and oceanography parameters
(Elsevier, 2024)The present study focused on understanding the seasonality of the phytoplankton biomass (chlorophyll a) distribution in the oligotrophic, Equatorial, and Southern Tropical Indian Ocean (ESTIO; 0-30�S and 60-90�E). The ... -
Carbohydrate and pigment composition of macroalgae in a kelp-dominated Arctic fjord
(Elsevier, 2024)A vast expanse of macroalgae is growing on the Arctic coasts under the changing environment. With a high content of carbohydrates, macroalgae are an important component of the coastal carbon cycle and an attractive raw ... -
