Degradation of Ice-Formed Beach Deposits

[摘要] 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 ridges1) protect the beach from storms for a few-week period,2) induce deposition of sand at the upper beachface and3) leave a lag deposit of cobble which may be a significant source of cobble transported across the beachface during summer storms.
