Source, bioavailability, and toxicity of metals in modern fjord sediments, west Spitsbergen, and their influence on sediment-associated biota
(FRONTIERS MEDIA SA, 2024)Metal contamination in the Arctic region has increased over the years despite its remote and isolated location. Thus, to evaluate the bioavailable fractions of various metals and their effects on sediment-associated biota, ... -
First record of a cold-seep squat lobster Munidopsis lauensis Baba and de Saint Laurent, 1992 (Anomura: Galatheoidea) from Indian waters
(Brazilian Crustacean Society, 2025)The present study reports the first zoogeographical record of the squat lobster Munidopsis lauensis Baba and de Saint Laurent, 1992 from a cold-seep site in the Krishna-Godavari Basin (Bay of Bengal), Northern Indian Ocean. ... -
Evaluation of fate of organic matter in sediment through microcosm experiments
(Wiley Online Library, 2024)Laboratory microcosm experiments help to understand the degradation pattern of different sources derived from organic matter (OM) at the sediment?water interface and relate it to field processes. Microcosm experiments were ... -
Variations in wind wave parameters measured in the coastal waters of north-eastern Bay of Bengal
Characteristics of the wind waves measured in the coastal waters of the northeastern Bay of Bengal are examined for 4 years. A comparison of the energy wave period (Te) with different wave periods shows that the average ... -
Seabed videography using indigenously built deep sea underwater camera
(Current Science, 2024)In the recent years, underwater visual survey is becoming as a powerful investigation technique, especially in focus to deep-sea study. In this paper, we report seabed investigation made with an easy-to-operate indigenously ... -
Crustal recycling and mantle heterogeneity beneath the Central Indian ridge, Indian Ocean,
(Elsevier, 2025)This study presents a new database including mineral chemistry, whole rock geochemistry and Sr-Nd isotopic compositions for basalts recovered from the Central Indian Ridge (CIR) with a view to evaluate melt generation ... -
The water budget of the Mahadayi river and its implications for the inter-state dispute
(Springer, 2024)We assess the water budget of the Mahadayi river, an inter-state basin on India's west coast with a long-running dispute. We seek to answer the following question: What is the discharge at any given location along the ... -
Disruptive synergism: The Co-occurrence of scyphozoan Pelagia noctiluca (Forssk l, 1775) swarms with green tide-causing dinoflagellate Noctiluca scintillans (Macartney) Kofoid & Swezy, 1921,
(Elsevier, 2025)The swarming behavior of certain scyphozoan clades, such as Pelagia noctiluca (Forsk l, 1775), highlights an evolutionary advantage. These adaptations promote survival and reproductive success, resulting in mass occurrences. ... -
Spatial and temporal variations in net primary production and long-term trends between 2003 and 2022 in the Indian Ocean: A synthesis using different models
(Elsevier, 2025)The measurements of net particulate primary production (NPP) with reference to space and time are limited in the Indian Ocean. Therefore, models are the only source of understanding spatial, temporal, and long-term variations. ... -
Sedimentary organic matter signature hints at the phytoplankton-driven biological carbon pump in the central Arabian Sea
(COPERNICUS GESELLSCHAFT MBH, 2025)The central Arabian Sea, a unique tropical basin, is profoundly impacted by monsoon wind reversal affecting its surface circulation and biogeochemistry. Phytoplankton blooms associated with high biological productivity and ... -
Anthropogenic litter pollution in the mangrove blue carbon ecosystem: Unveiling the spatial distribution, composition, source delineation and mitigation measures along the Goa coast, India
(Elsevier, 2025)Plastic litter pollution has emerged as a critical environmental issue globally, and coastal habitats are particularly vulnerable to its detrimental effects. The west coast of India, renowned for its rich biodiversity and ... -
Unprecedented warming impacts on phytoplankton and special emphasis on diatom-diazotroph associations in the oligotrophic waters of the Eastern Arabian Sea
(Elsevier, 2025)The impact of anomalous warming on the phytoplankton dynamics in the euphotic zone (0 60 m depth) of the eastern Arabian Sea (EAS) during the southwest monsoon (SWM 2020) was investigated along the 68 E transect from 8 N ... -
Anticancer and anti-inflammatory activity and untargeted metabolite profiling by UPLC-ESI-QTOF of crude extracts of mangrove endophytic fungus Aspergillus stellatus LM-03
(Taylor & Francis, 2025)Mangrove ecosystem is diverse habitat for number of medicinally important microorganisms including fungi. Scientific research from last three decade emphasises it potential in important secondary metabolites production, ... -
Influence of ambient geochemical and microbiological variables on the bacterial diversity in a cold seep ecosystem in North Indian Ocean
(Elsevier, 2025)Cold seeps are oases for biological communities on the sea floor around hydrocarbon emission pathways. Microbial utilization of methane and other hydrocarbons yield products that fuel rich chemosynthetic communities at ... -
Phytoplankton assemblage and restricted bloom of Merismopedia sp. (Meyen, 1839) in an anthropogenically stressed tropical estuary (Ulhas estuary), India
(Springer, 2025)The present study evaluates the effect of nutrients and their spatio-temporal variation in determining the composition of phytoplankton assemblage. The study recorded the restricted bloom of Merismopedia sp. (Meyen, 1839) ... -
