Terry / Lau / Etienne Reef-Platform Coral Boulders

The primary goal here is to present a treatise on the significance and value of coarse clastic carbonate sediments (i.e. large coral boulders) on tropical coastlines for understanding both modern and pre-historical (Holocene) high-magnitude marine inundation events.  There has been a rapid groundswell of interest in large carbonate blocks on tropical coasts over the last decade, yet it is not widely appreciated that such features were observed and recorded back in the early explorations of Matthew Flinders on the Great Barrier Reef in the 1800s. This book will illuminate how various characteristics of datable carbonate blocks torn up from coral reefs and deposited on reef platforms yield importance evidence about the storms and tsunamis that emplaced them over decadal and centennial timescales.  No comprehensive review has so far been published.  A need now exists for a ‘definitive reference’ on coral boulder research, which details the earliest observations, changing terminology, sedimentology, and relevance for coastal hazard research in the tropics.  A wide range of examples will be incorporated from across Asia, Australia, the Pacific and the Americas, as well as a full up-to-date review of the existing literature.

Etienne, Samuel
James Terry received his BSc (Hons) (1988) and PhD (1992) from the University of Wales at Swansea in the UK. Currently he is Associate Professor at the National University of Singapore, since 2008. Before that he served as Head of the School of Geography at the University of the South Pacific based in Fiji, where he worked for 12 years in total from 1996-2008. Being a Physical Geographer, James has specialist interests in tropical geomorphology, natural hazards and island geoscience. He has over 20 years of research and consulting experience across many aspects of tropical environments, including climatic change and extremes, fluvial and coastal responses to large-magnitude events, water resource issues, and adaptation to natural hazards.
