The aim of this study was to develop a methodology to assess the degree of multidisciplinarity and international co-operation between scientists working on Deception Island, using techniques based on social network analysis. A database was built of the scientific output, as represented by published articles, on Deception Island between 1964–2012. From the 173 published articles, the main topics, the temporal trends, the profile of the principal journals, and the contributions made by each country, research institution and scientist were obtained. The data presented show a significant role played by four of the six nations belonging to the Deception Island Management Group. However, collaborations between researchers in different fields was unusual and co-authoring by researchers from different countries was relatively low. These results show that there is a need to strengthen international co-operation, a highly advisable strategy in Antarctica due to the complexity of logistics and high operational costs. Studies such as this may help to identify synergies between institutions and researchers from different nations, improving the scientific collaboration in this area of priority for conservation and management.
