Oceanographic research ship capabilities in ice

The need for an iceworthy research ship to meet the research requirements of the Alaskan Arctic Region has recently been highlighted by Elsner (1) and documented by Dinsmore (2). Recommendations to acquire such a vessel in the immediate future have been made. The purpose of this paper is to present the results of recent icebreaking model experiments which have characterized the behavior of an oceanographic research ship hull form in ice covered waters.
