This book includes a selection of oral and poster presentations from qOnshore-Offshore Relationships on the Nordic Margin Conferenceq held in Trondheim in 2002. The conference was jointly arranged by the Norwegian Geological Society (NGF) and the Norwegian Petroleum Society (NPF), and attempted, through different thematic sessions, to bridge the gap often noted between industry and academic research. The first part of the conference included presentations under the theme qBasement control on offshore structuringq with representative articles from that segment included in this book and covering topics that range from analysis of vertical movements of basement substrates to the deep structural architecture of the Norwegian Sea to the development of the Jan Mayen microcontinent. These papers set the scene for the second segment of the conference, qLinking uplift and erosion with subsidence and depositionq, that in the present book include articles related to the Triassic to Present-day infill history in the Norwegian and northern North Seas. The last segment of the conference addressed qNew challengesq with respect to natural features of the deep-water areas that necessitate particular consideration and innovation on the part of research and industry to mitigate risk and maximize returns from field development. In this book, the articles addressing this theme present analyses of the enormous submarine slides that took place during the Holocene in the Norwegian Sea, and are of particular interest to the developers of the Ormen Lange gas field; other articles address the occurrences of gas hydrates in the near sea floor and the challenges presented in identifying and protecting the Lophelia cold-water reefs in the region. * Processes creating the structural framework for the deposition and depositional patterns in the Norwegian Sea and northern North Sea * Erosion and subsequent deposition of sediments in the subsiding deep-water basins in the Norwegian Sea area and northern North Sea * Challenges the oil industry has met in the deep-water areas of the Norwegian continental shelf18).
