9503401 Wells There has been no systematic study of the phenomena of subsurface cementation of beach sand and its subsequent subaerial exposure as beachrock in intertidal environments. This may have important implications for sedimentological, wave and current processes in the littoral zone. The PI will carry out a pilot project in Puerto Rice to study beachrock and coastal stability. 16 beach profiles will be measured and instruments deployed to study lateral variations and processes. USGS and University of Puerto Rico scientists will also collaborate. ***

9503401威尔斯 对于海滩砂的次表层胶结现象及其随后在潮间带环境中作为海滩岩暴露在空中的现象，还没有系统的研究。 这可能对沿岸的区域的沉积学、波浪和水流过程具有重要影响。 PI将在波多黎各赖斯开展一个试点项目，研究海滩岩石和海岸稳定性。 将测量16个海滩剖面，并部署仪器研究横向变化和过程。 美国地质勘探局和波多黎各大学的科学家也将进行合作。 ***
