Bibliometric Analysis of Collaboration Network and the Role of Research Station in Antarctic Science

Abstract

Due to the large scale of Antarctic science, scientific collaboration is required for conducting scientific research. In this study, we attempted to investigate collaboration network and the role of research station in Antarctic science based on bibliometric data from 1995 to 2014. We confirmed that geographical proximity tends to be important for scientific collaboration by employing community detection in the network. This result raises the question about what the role of research station in Antarctica is. We tried to reveal its role by focusing on five countries, Belgium, China, Czech Republic, India, and Korea that constructed new research stations during the last decade. Relative growth rate, a value to measure the growth of publications, didn't differ much around the construction period compared to those in other periods for these countries except Belgium. However, we found geographical keywords emerged around the construction for all five countries. These keywords were utilized to observe national research activities in Antarctica. They show where countries started to be concerned about after the construction.

Measuring national capability over big science’s multidisciplinarity: A case study of nuclear fusion research

“…A country's strategic decisions for particle accelerators can be traced with comparative advantages on topical clusters. In Antarctic science, research stations may increase research capabilities on geographydependent topics [60,61] because its location expands the range of research activities. An increasing comparative advantage on spatial topics will support this idea.…”

A Systematic Review of Collaborative Networks: Implications for Sensing, Smart and Sustainable Enterprises

“…Collaboration is proven an effective strategy to improve service levels, process stability and the utilization of productive resources [49]. Collaboration among researchers aims to improve the quality of research, increase scientific productivity [50] and longevity [51]. In R&D projects, collaboration fosters the exchange of knowledge, sharing of resources and costs among employees, improving expected results, and industry performance [52].…”

Antarctic science in Chile: a bibliometric analysis of scientific productivity during the 2009–2019 period

“…The creation of the Chilean Antarctic Institute ( Instituto Antártico Chileno ; INACH) in 1963 was inspired by the obligations assumed by the country as part of the Antarctic Treaty (signed in 1959) in terms of carrying out scientific research within a framework of international cooperation. Chile as a claimant nation and as a Consultative Party has conducted substantial scientific work on the continent, as shown by several bibliometric studies (Dudeney & Walton 2012, Gray & Hughes 2016, Kim & Jung 2016).…”
