Description:
This review identifies four themes in shore platform research: 1) the role of marine and subaerial processes in platform development; 2) morphology of shore platforms; 3) modelling platform development; and 4) measuring rates of erosion. The view that shore platforms have a wave-cut origin has dominated the literature in the last 20 years. It is argued that this wave-cut origin remains to be convincingly demonstrated. Attempts to link platform morphology with the process environment have proven difficult but a recent demarcation between platform morphologies based on wave erosion and rock resistance offers an interesting and new way to consider platform morphology. Attempts to model platform development have been handicapped by a lack of data and a clear understanding of development processes. All models are based on the premise that platforms have a wave-cut origin, yet this has not been adequately demonstrated. There are a number of contradictions between models that require resolution. Erosion rates have been measured using the micro-erosion meter, but these studies are restricted both temporally and spatially. The contribution of microscale erosion relative to other forms and scales remains unknown. A number of issues are raised and suggested as being suitable questions for future research. It is proposed that real advances in understanding shore platforms will be aided by collaborative work between researchers from a number of morphogenetic environments.
