Over the last 50 years, the North Sea and Atlantic Margin, and more recently the Barents Sea, represented key study areas for academic and professionals interested in the exploration for and production of hydrocarbon from the Earth’s subsurface. Nowadays, these areas may play a major role in the so-called ‘energy transition’, with the energy industry now seeking to reduce emissions related to hydrocarbon consumption, and leading the development of carbon capture and storage activities, such as the Northern Light project (https://northernlightsccs.com). Consequently, there is an increasing interest in advancing our knowledge regarding the stratigraphy, sedimentology, and tectonic development of the North Sea, Atlantic Margin, and Barents Sea with a cross-border approach.
