Les changements g\u00e9ologiques sont g\u00e9n\u00e9ralement per\u00e7us comme des processus se d\u00e9roulant sur de longues p\u00e9riodes de temps. La comparaison des donn\u00e9es multifaisceaux acquises au cours de la derni\u00e8re d\u00e9cennie prouve le contraire.<\/span><\/p>\n

Paull et al. (2022)<\/span><\/a> ont compar\u00e9 les donn\u00e9es cartographiques recueillies par un v\u00e9hicule sous-marin autonome (AUV) lors de r\u00e9cents relev\u00e9s avec les donn\u00e9es cartographiques acquises par le NGCC <\/span>Amundsen <\/span><\/i>\u00e0 l\u2019aide d\u2019un sonar multifaisceaux en 2010. Leurs r\u00e9sultats r\u00e9v\u00e8lent des changements morphologiques rapides, tels que le d\u00e9veloppement de nouvelles d\u00e9pressions aux c\u00f4t\u00e9s abrupts jusqu\u2019\u00e0 28 m de profondeur, associ\u00e9s au d\u00e9gel du perg\u00e9lisol sous-marin.<\/span><\/p>\n

L\u2019\u00e9tendue et la port\u00e9e de ces changements sur les plateaux arctiques sont encore inconnues, car de multiples relev\u00e9s bathym\u00e9triques sont n\u00e9cessaires pour les identifier. Les changements rapides des fonds marins associ\u00e9s au d\u00e9gel du perg\u00e9lisol sous-marin peuvent \u00eatre un processus important qui doit \u00eatre \u00e9tudi\u00e9 plus en profondeur.<\/span><\/p>\n
