| Summary: | The deterioration of pack ice due to wave action on the Grand Banks, offshore Newfoundland, is investigated. A description of wave effects on pack ice is provided that is based on the observations of one of the authors (JB) during several icebreaking voyages on the East Coast of Canada and in the Eastern Arctic. Sea ice deterioration in the region is observed to be dominated by swell wave action which extends to relatively long distances within the ice pack. Heat flux due to wave action is incorporated in an ice dynamics forecast model and used to evaluate the role of wave action on ice deterioration. A test case from the 2017 ice season is used to calibrate and examine the performance of the proposed formulation. The paper compares hindcasts of ice extent and concentration to observations. The results indicate that deterioration of the pack ice due to wave action is significant during severe storm conditions. Peer reviewed: Yes NRC publication: Yes |
