Abstract

Monsoon-influenced coasts commonly exhibit a clear seasonal pattern that may be undergoing variability associated with increased storm activity. A notable example is a rare tropical cyclone event in Malaysian waters in January 2019 that affected both marine and terrestrial environments in an exceptional context that diverged from seasonal Monsoon-influenced coastal geomorphic responses to waves. Storm Pabuk made landfall in the South China Sea, with its tail impacting Bidong Island, a coral reef island in Terengganu, Malaysia. Using data on coral coverage cover, aerial imagery obtained from an unmanned aerial vehicle (UAV) and numerical simulations of waves, this study investigates the shoreline changes caused by the cyclone, focusing on coral distribution and wave parameter modeling. The results reveal, unsurprisingly, that the coral reef beach was negatively affected, with a significant reduction in live coral cover. Interestingly, however, the shoreline saw an increase in beach sediment accumulation as well as shoreline length, highlighting both the negative erosion impacts of storms on corals but also their tendency to liberate new beach sediment. The effects of Storm Pabuk illustrate the importance of considering exceptional events in the study of Monsoon-influenced beach dynamics, especially in settings characterized by corals.

期刊介绍： Marine Geology is the premier international journal on marine geological processes in the broadest sense. We seek papers that are comprehensive, interdisciplinary and synthetic that will be lasting contributions to the field. Although most papers are based on regional studies, they must demonstrate new findings of international significance. We accept papers on subjects as diverse as seafloor hydrothermal systems, beach dynamics, early diagenesis, microbiological studies in sediments, palaeoclimate studies and geophysical studies of the seabed. We encourage papers that address emerging new fields, for example the influence of anthropogenic processes on coastal/marine geology and coastal/marine geoarchaeology. We insist that the papers are concerned with the marine realm and that they deal with geology: with rocks, sediments, and physical and chemical processes affecting them. Papers should address scientific hypotheses: highly descriptive data compilations or papers that deal only with marine management and risk assessment should be submitted to other journals. Papers on laboratory or modelling studies must demonstrate direct relevance to marine processes or deposits. The primary criteria for acceptance of papers is that the science is of high quality, novel, significant, and of broad international interest.
