The effects of tidal jacking on ice displacement and strain in the nearshore environment

Observations on the nearshore movement of an ice cover were made at two locations in the North Baffin Area of the Canadian Arctic. These measurements were made at half hourly and hourly intervals for periods up to 24 hours. From these measurements, a consistent pattern of offshore ice cover movement...
