Rocky coasts, often comprising extensive foreshore platforms and steep cliffs, are subject to the combined influence of marine and subaerial environments and the properties of the rock-mass. The interaction of these factors defines the rates and mechanisms of change. Rates of erosion are often imperceptibly low, hence recording the process-response relationships governing rocky coast behaviour remains challenging. The requirement for enhancing understanding into the dynamics of rocky coast behaviour holds particular significance in the context of global sea-level rise and the forecast increase in the future occurrence of extreme weather. This also provides the key to understanding the significance of rocky coasts in palaeo-environmental reconstruction. Establishing consistent quantitative records of coastal processes and landform responses is critical for analysing changes at the coast across a variety of spatial and temporal scales. Only with this data can sediment generation and flux, coastal landform evolution and connectivity between the coastline and nearshore be assessed. Furthermore, the understanding of these processes is vital for guiding coastal management and the prediction of future coastlines. Recent developments in our ability to collate datasets of increasing extent and resolution open exciting opportunities for exploring coastal dynamics. We seek to develop a forum to promote and explore these new datasets, with a focus upon integrating the understanding of short- and long-term processes that act upon rocky coastlines. We welcome submissions on all aspects of the processes, evolution, and dynamic behaviour of rocky coasts, including (but not limited to) rockfall and landslides; erosional processes on shore platforms; quantification of erosion rates and patterns; sediment transport; and responses to environmental change.
