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 ... -
Seasonal dynamics of mangrove outwelling and its impact on estuarine productivity: insights from multi-parameter analysis across tidal variations
(Springer, 2024)Tropical mangroves are subjected to extreme environmental conditions yet remain highly productive ecosystems. The Mandovi and Zuari estuaries of Goa on the western coast of India are lined by mangroves and are a rich source ... -
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 ... -
3D local earthquake tomography of the Andaman-Nicobar subduction zone using ocean-bottom seismometer data
(Seismological Society of America, GeoScienceWorld, 2024)The Andaman-Nicobar (A-N) subduction zone is one of the most seismically active subduction zones of the world where the Indian plate subducts beneath the Burmese-Sunda plate. Imaging the subducting Indian plate (SIP) ... -
Effect of �spiciness� on the intensification of cyclones over Arabian Sea - A case study on Biparjoy
(Springer, 2024)In recent decades, there has been notable variability in the occurrence, frequency, and intensification of cyclones worldwide, and a significant trend has emerged in the northern Indian Ocean, notably the Arabian Sea. The ... -
Methane gas flares in the forearc basin of the Andaman-Nicobar subduction zone
(Frontiers Media SA, 2024)Gas hydrates deposits in the Andaman forearc basin are inferred from seismic data and confirmed by drilling/coring during the NGHP-01 expedition. We present new evidence of gas flares in the Andaman forearc basin, detected ... -
Report of epibiont ciliates (Ciliophora) found on meiofauna from Mumbai and adjacent coastal areas of India
