In this study, the effects of sea level rise (assumed to continue at present, at the time of the study, rates, which the authors noted was likely conservative), wave fetch, wind speed and direction were examined and the resultant erosion rate was estimated for the Western and Eastern shore of Uppands, Port Isobel and Tangier Island by selecting 10 points along the western and eastern shoreline of all the islands.

Using the Great Barrier Reef as their study case, they estimated the evolution of the region over the last 14,000 years and showed that (1) high sediment loads from catchments erosion prevented coral growth during the early phase of sea level rise and favoured deep offshore sediment deposition; (2) how the fine balance between climate, sea level, and margin physiography enabled coral reefs to thrive under limited shelf sedimentation rates at 6,000 years before present; and, (3) how over the last 3,000 years, the decrease of accommodation space led to the lateral extension of coral reefs consistent with available observational data.
