Sea ice thickness measurement using episodic infragravity waves from distant storms
International audience The thinning and retreat of Arctic sea ice is one of the most dramatic manifestations of recent climate warming. Though ice extent can be routinely monitored by satellite, ice thickness is far more difficult to measure operationally. We show that small amplitude, long period w...

International audience The thinning and retreat of Arctic sea ice is one of the most dramatic manifestations of recent climate warming.
