During the last years, a large amount of information was gathered and shared in one unique project for the development of a representative system of MPAs in Domain 1. This process integrates, compiles, analyses and exposes a large amount of information, not only contributing to the best science available but also providing a platform for the sharing and visualization of information, further improving the decision making process. Data was shared according to CCAMLR rules, providing the opportunity for other countries to develop their own analyses. During these years a solid foundation of collaboration and cooperation amongst Members involved in the development was built. However, there are still a number of Members currently doing research and/or undertaking commercial activities, that desirably could became involved in the development of the MPA proposal and contribute to the state of knowledge. This document highlights the progress made towards a common framework for Domain 1 MPA and further encourages the establishment of a cooperation network among countries.
