Microbe, climate change and marine environment: Linking trends and research hotspots.

Microbes, or microorganisms, have been the foundation of the biosphere for over 3 billion years and have played an essential role in shaping our planet. The available knowledge on the topic of microbes associated with climate change has the potential to reshape upcoming research trends globally. As climate change impacts the ocean or marine ecosystem, the responses of these "unseen life" will heavily influence the achievement of a sustainable evolutionary environment. The present study aims to identify microbial-related research under changing climate within the marine environment through the mapping of visualized graphs of the available literature. We used scientometric methods to retrieve documents from the Web of Science platform in the Core Collection (WOSCC) database, analyzing a total of 2767 documents based on scientometric indicators. Our findings show that this research area is growing exponentially, with the most influential keywords being "microbial diversity," "bacteria," and "ocean acidification," and the most cited being "microorganism" and "diversity." The identification of influential clusters in the field of marine science provides insight into the hot spots and frontiers of research in this area. Prominent clusters include "coral microbiome," "hypoxic zone," "novel Thermoplasmatota clade," "marine dinoflagellate bloom," and "human health." Analyzing emerging trends and transformative changes in this field can inform the creation of special issues or research topics in selected journals, thus increasing visibility and engagement among the scientific community. • A comprehensive scientometric analysis has been conducted to evaluate the quantitative relationship between microbial communities, climate change, and the marine ecosystem. This assessment employs advanced statistical techniques to analyze the existing body of literature and identify significant patterns and trends. • The anticipated key research focus in the near future is the "coral microbiome," with "human health" being a close second. This projection emphasizes the growing importance of understanding the role of microorganisms in coral reef ecosystems and their potential implications for human well-being. • Among the most impactful keywords identified within the subject matter are "microbial diversity" and "ocean acidification." These terms highlight the critical need for continued investigation into the complex interplay between marine microbial communities and the effects of climate-induced oceanic changes, such as increased acidity levels. • The study also underscores the importance of robust international collaboration in advancing our understanding of this interdisciplinary field.
