Figure from UNEP: These images show a combination of a rocky, hilly headland along with a small river delta and swampy coastal strip. A low-lying wetland area connects the northern and western ocean fronts. An integration of natural and agricultural ecosystems operating prior to the tsunami combined rice cultivation, and fish/shrimp ponds (tambak), alongside natural delta mangrove forests and wetlands. Coastal forests and onshore reefs are also present. The effect of the tsunami is clearly evident. It scoured out the low lying delta land, destroyed fish ponds and removed mangrove cover. Volumes of soil and silt have evidently been carried out to sea expanding the area of the small lake by a factor of approximately 10. There has been removal of the sandy beaches (important in some locations for turtle nesting) and deposition of silt or mud on the reef. Apparently minor effects on the integrity of the rocky vegetated shoreline surrounding the headland are likely due to the resilient nature of the substrata, as well as dense natural vegetation cover and the sloping nature of the shore.

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, created to facilitate research to address fundamental questions in evolutionary science. He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards. Craig’s popular writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
