Marine remote sensing, as a representative interdisciplinary field, has garnered increasing attention in recent years, leading to a surge in relevant scientific literature. Focusing on "Marine remote sensing" as the study subject, this paper retrieved global scientific literature related to marine remote sensing published between 2010 and 2020 from Web of Science Core Collection database. Complex network analysis and centroid migration algorithms were adopted in the study to reveal the collaboration patterns and migration characteristics of research productivity in the field of global marine remote sensing. Additionally, the K-core analysis method was employed to identify core, bridge, and peripheral nodes within the national cooperation network, offering a comprehensive quantitative portrayal of the global marine remote sensing collaboration network. The findings reveal an upward trajectory in marine remote sensing paper publication and a concurrent increase in international collaboration. China's contribution to marine remote sensing is rapidly expanding, and there is an observable shift of the publication center from west to east. Analysis of centrality measurements and hierarchical structure underscores the consistent dominance of the United States as the central player in the collaboration network. Degree and betweenness centrality measurements indicate a strengthening trend in international collaboration for European countries and China, illustrate their pivotal participants role on the global scale. Changes in closeness centrality highlight the accelerated pace of information dissemination within the collaboration network.
