Unmelted cosmic metal particles in the Indian Ocean
(Wiley, 2017)Fe?Ni metal is a common constituent of most meteorites and is an indicator of the thermal history of the respective meteorites, it is a diagnostic tool to distinguish between groups/subgroups of meteorites. In spite of ... -
Unraveling the land-based discharge of microplastics from sewers to oceans - A comprehensive study and risk assessment in wastewaters of Goa, India
(Elsevier, 2024)Owing to their pervasive dispersion in the environment and their potential ramifications on both marine life and human health, microplastics (MPs) are of increasing concern. However, there is still a lack of research on ... -
Unraveling the role of bacterial communities in mangrove habitats under the urban influence, using a next-generation sequencing approach
(Elsevier, 2024)Mangrove ecosystems are vital coastal habitats with rich biodiversity and play a significant role in carbon sequestration, these habitats are facing mounting threats from rapid urbanization. This study delves into assessing ... -
Unraveling the sources of atmospheric organic aerosols over the Arabian Sea: Insights from the stable carbon and nitrogen isotopic composition
(Elsevier, 2022)The isotopic composition of stable carbon (δ 13 C) and nitrogen (δ 15N) in marine aerosols influenced by the continental outflows are useful proxies for understanding the aging and secondary formation processes. Every ... -
Unseen and unsung heroes: The microbes
(WWF for Nature-India, 2004)Fungi are larger microorganisms and their bodies are mostly filamentous, the filaments being called hyphae. It is now believed that fungi evolved from an ancestor that was also common to animals. The width of the fungal ... -
Untangling the effect of organic matter and dissolved oxygen on living benthic foraminifera in the southeastern Arabian Sea
(Elsevier, 2021)We studied the relationship between organic carbon in sediments (%Corg), bottom water dissolved oxygen and living benthic foraminifera in a marginal marine upwelling setting from the southeastern Arabian Sea to develop ... -
Unusual blooms of green Noctiluca miliaris (Dinophyceae) in the Arabian Sea during the winter monsoon
(American Geophysical Union, 2009)A large-scale, ongoing study conducted by the National Institute of Oceanography, India, from 2003 onward in support of India’s ocean color program, has documented for the first time ever the appearance of extensive blooms ... -
Unusual congregation of salps off Veraval and Bombay, west coast of India
(CSIR-NISCAIR, 1988)During September to October swarming of salps occur along the coasts off Veraval and Bombay. These congregations off Veraval are contributed by the single species Pegea confoederata recording an unusual biomass as high as ... -
Unusual rise in mercury-resistant bacteria in coastal environs
(Springer, 2003)A sharp rise in mercury-resistant bacteria (MRB) capable of tolerating very high concentration of Hg was observed over the last 3-4 years in the coastal environs of India. While none or negligible colony-forming units (CFU) ... -
Unusual thickening of collarette in Sagitta bedoti (Chaetognatha) from the polluted environments of Bombay coast
(NISCAIR, New Delhi, 1992)Sangitta bedoti dominated the chaetognath fauna of the nearshore waters of Bombay. S. bedoti from the polluted creek environments developed an unusually bulky collarette which extended from the neck to the seminal vesicles. ... -
