About The Cover
The image shows the atoll reef front presently occupied by sand, seagrass, spur and groove, and pinnacle at Pag-asa Island within the Kalayaan Island Group in the West Philippine Sea. This atoll reef features four terraces up to 120 meters deep that formed during sea level rise events since ~ 15,000 years ago. Pag-asa Island is threatened by coastal erosion, more frequent inundation, and groundwater salinization amid rising sea levels due to global warming and continuing subsidence. To learn more, go to pages 291–306.
