The Antarctic Roadmap Challenges (ARC) project identified critical requirements to deliver high priority Antarctic research in the 21st century. The ARC project addressed the challenges of enabling technologies, facilitating access, providing logistics and infrastructure, and capitalizing on international co-operation. Technological requirements include: i) innovative automated in situ observing systems, sensors and interoperable platforms (including power demands), ii) realistic and holistic numerical models, iii) enhanced remote sensing and sensors, iv) expanded sample collection and retrieval technologies, and v) greater cyber-infrastructure to process ‘big data’ collection, transmission and analyses while promoting data accessibility. These technologies must be widely available, performance and reliability must be improved and technologies used elsewhere must be applied to the Antarctic. Considerable Antarctic research is field-based, making access to vital geographical targets essential. Future research will require continent- and ocean-wide environmentally responsible access to coastal and interior Antarctica and the Southern Ocean. Year-round access is indispensable. The cost of future Antarctic science is great but there are opportunities for all to participate commensurate with national resources, expertise and interests. The scope of future Antarctic research will necessitate enhanced and inventive interdisciplinary and international collaborations. The full promise of Antarctic science will only be realized if nations act together.

Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore, the international Antarctic community came together to ‘scan the horizon’ to identify the highest priority scientific questions that researchers should aspire to answer in the next two decades and beyond. Wide consultation was a fundamental principle for the development of a collective, international view of the most important future directions in Antarctic science. From the many possibilities, the horizon scan identified 80 key scientific questions through structured debate, discussion, revision and voting. Questions were clustered into seven topics: i) Antarctic atmosphere and global connections, ii) Southern Ocean and sea ice in a warming world, iii) ice sheet and sea level, iv) the dynamic Earth, v) life on the precipice, vi) near-Earth space and beyond, and vii) human presence in Antarctica. Answering the questions identified by the horizon scan will require innovative experimental designs, novel applications of technology, invention of next-generation field and laboratory approaches, and expanded observing systems and networks. Unbiased, non-contaminating procedures will be required to retrieve the requisite air, biota, sediment, rock, ice and water samples. Sustained year-round access to Antarctica and the Southern Ocean will be essential to increase winter-time measurements. Improved models are needed that represent Antarctica and the Southern Ocean in the Earth System, and provide predictions at spatial and temporal resolutions useful for decision making. A co-ordinated portfolio of cross-disciplinary science, based on new models of international collaboration, will be essential as no scientist, programme or nation can realize these aspirations alone.

Pangea Resources International AG, Switzerland, has put forward the concept of an international geological repository in an Australian desert area, for final disposal of certain of the world's high-level radioactive wastes and surplus fissile materials. Already publicly contentious in Australia, the concept raises unusual issues in safety and environmental assessment. It is timely, therefore, to consider why and how an initial case for such a repository might be made, in comparison with national options for high-level waste disposal that it might displace.
There are several stages ahead of development of a formal safety case for an international repository. The first, and almost certainly the most challenging, is winning of public and political acceptance in the host country that such a repository is the ‘best’ solution to a global problem.
We consider the basic need to identify and encompass the concerns of widely disparate stakeholders — industry, governments, national and international regulators, environmental interest groups and the public at large — so that public and political debates can be informed effectively. Many key issues will require comparison both of risks arising from very different operations, and of dissimilar prospective safety performances of complete disposal systems over periods spanning thousands of generations. Nevertheless, we conclude that the validity of such a comparative assessment could be assured by consistent application of a judicious blend of assessment techniques across the alternatives. We also conclude that its usefulness as a vehicle for public discussion would be enhanced by careful attention to public concerns, and by transparently independent review by scientific, technical, sociological and ethical specialists.
