| Abstract | Polar and subpolar coasts are distinctive because of extreme seasonality and the presence of ice (predominantly tidewater glaciers, ice shelves, sea ice, and ground ice). Sea ice plays a protective role
but may be either erosional or constructive when mobile. Wave activity, though effective mainly during the short summer, imposes a strong morphological signature on most sedimentary coasts. Unlithified coasts in permafrost are widespread on the
Arctic Coastal Plain, where combined thermal and mechanical processes promote rapid erosion in ice-rich deposits. Antarctic and sub-Antarctic coasts are mainly dominated by rock or ice, as are parts of the Arctic coast. |
