Measurement of ridge sails in the Beaufort Sea

Ice pressure ridges in the southern Beaufort Sea near Tuktoyaktuk were surveyed in April 1986. Sail cross-section profiles and ice-block dimensions of ridges of extreme heights were measured at several locations along the outer edge of the landfast ice. Statistical distributions of sail heights as well as correlations between sail dimension and between ice block dimensions are obtained. Geographical distribution of sail dimensions and longitudinal changes along individual ridges are examined.Les cr\ueates de pression des glaces dans le sud de la mer de Beaufort pr\ue8s de Tuktoyaktuk ont \ue9t\ue9 analys\ue9s au mois d'avril 1986. Les profils en coupe des voiles et les dimensions des blocs de glace des cr\ueates de tr\ue8s grande hauteur ont \ue9t\ue9 mesur\ue9s \ue0 plusieurs endroits le long de la bordure ext\ue9rieur de la glace bordi\ue8re. La r\ue9partition statistique des hauteurs des voiles et les relations entre les dimensions des voiles et celles des blocs de glace ont \ue9t\ue9 obtenues. La r\ue9partition g\ue9ographique des dimensions des voiles et les modification longitudinales le long des cr\ueates individuelles ont \ue9t\ue9 examin\ue9es.Peer reviewed: YesNRC publication: Ye
