Permafrost coastlines represent a large portion of the world's coastal area and these areas have become increasingly vulnerable owing to the changing climate and its strong dynamics observed over the past decades (Irrgang et al., 2022). The predominant mechanism of coastal erosion in these areas has been identified through several observational studies as thermomechanical erosion-a joint removal of sediment through the melting of interstitial ice (thermal energy) and abrasion from incoming waves (mechanical energy). This work provides an overview over novel avenues that are useful for a better understanding of processes and interactions of ocean waves and Arctic coastlines. The work presents some of the recent erosional observations from a cold room and wave flume setup as well as micro CT measurements. We report common pitfalls, and provide recommendations for the developments that are required of the community to better facilitate future experimental work to understand the physical processes.
