The Seventh International Conference on Port and Ocean Engineering under Arctic Conditions: POAC 83. Vol. 4

POAC 83, which was held in Helsinki, Finland, was the seventh in the series of international conferences dealing with various theoretical and practical aspects of arctic technology in navigation and coastal engineering. Ice problems in polar marine areas and harbours, as well as ice loads on coastal structures were the basic subjects of discussion in the conference. Other subjects were the utilization of arctic energy resources and the problems associated with the increasing industrial activities onshore and offshore. As a local question, various aspects of navigation in the Baltic and in the Gulf of Bothnia were discussed. The papers of POAC 83 have been published in four volumes.
