The rapid decline of summer sea ice cover in the Western Arctic has been accompanied by a dramatic increase in the sea state of the region. Ocean waves are now more common throughout the region, including multiple energetic swell events each summer. These waves interact with the sea ice and help to both form and define the expanding Marginal Ice Zone (MIZ) of the Western Arctic. The attenuation of waves into the MIZ is well-documented, but the resulting transfers of energy and momentum are less well-constrained. This talk reviews recent observations of energy and momentum transfers in the wave-ice-ocean system, including implications for sea ice retreat and coastal morphology.
