| Résumé | (disponible en anglais seulement)
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. |
