Abstract：The marine carbon sink is a key component of the global carbon cycle and climate regulation,and its study is of great significance for addressing climate change and protecting marine ecosystems.In this study,we first reviewed the definition,composition and distribution characteristics of the ocean carbon sink,and analyzed the impacts of anthropogenic factors and the natural environment on the ocean carbon sink.Secondly,CiteSpace software was used to conduct information data mining of ocean carbon sink related literature in the Web of Science core database during 2001-2024,to map the collaborative network of authors,journals,institutions,and countries(regions),and to identify hotspots at the forefront of ocean carbon sink research.Then,the keywords of ocean carbon sinks are clustered and analyzed,and the keyword clustering map and emergence table are drawn to explore the hot trends and future directions of ocean carbon sinks research.The study shows that the ocean carbon sink plays an important role in the global carbon cycle and climate regulation,but it faces threats from anthropogenic and natural factors.Future research needs to strengthen the monitoring,assessment and management of ocean carbon sinks and explore their role mechanisms and influencing factors in order to better respond to climate change and protect marine ecosystems.This study provides a scientific basis and guidance for further research on ocean carbon sinks,as well as new ideas and methods for global climate change and the maintenance of ecological balance.
