Degradation of Ice-Formed Beach Deposits

Ice-push ridges and kaimoos are depositional features formed by ice on Tabusintac Beach, New Brunswick. These features are transformed into ridge-and-runnel systems when subjected to wave processes. Kaimoo and ice-push ridges 1) protect the beach from storms for a few-week period, 2) induce deposition of sand at the upper beachface and 3) leave a lag deposit of cobble which may be a significant source of cobble transported across the beachface during summer storms.
