The Changing Role of Geological Surveys
Senior managers and Heads of Geological Survey Organizations (GSOs) from around the world have contributed a collection of papers to provide a benchmark on how GSOs are responding to national and international needs in a rapidly changing world. GSOs continue to provide key scientific information about Earth systems, natural hazards and climate change. As countries adopt sustainable development principles and the public increasingly turns to social media to find information about resource and environmental issues, the generation and communication of Earth science knowledge become increasingly important. This volume provides a snapshot of how GSOs are adapting their activities to this changing world. The different national perspectives presented converge around several common themes related to resources, environment and big data. Climate change and the UN's Sustainable Development Goals provide an increased incentive for GSOs of the world to work in harmony, to generate knowledge of Earth systems and to provide solutions for sustainable management of the planet.
Seabed mapping in Norwegian waters: programmes, technologies and future advances

Abstract
A holistic understanding of the oceans as part of the Earth system is imperative for the future management and sustainable utilization of the ocean's natural resources. Increasing pressures on global resources have been accompanied by important advances in acoustic remote sensing technologies, allowing us to map the seabed in unprecedented detail. The MAREANO (Marine areal database for Norwegian waters) programme in Norway, one of the world's largest seabed mapping programmes, is designed to close the knowledge gaps with the use of the new technologies.
To date, since the start in 2005, c. 1170 million NOK (Norwegian kroner), equivalent to c. US$115m have been allocated to this programme (2005–20). This paper outlines the development of MAREANO and other large marine mapping and science programme proposals in Norway, and considers which factors influenced whether they were realized or not. In conclusion, funding of MAREANO came as a result of the convergence of political needs, technical capacity and multi-institutional co-operation.
We further give an overview of the new and improved seabed mapping technologies, and finally we discuss the Norwegian programmes in connection with similar major international ongoing programmes and new initiatives and take a look at possible advances in future seabed mapping.
