This two-year award provides support for US-France cooperative research on the nature of Amazon sediment accumulation along the Guianas-Amapa coast of South America. The collaboration involves the research groups led by Mead Allison of Texas A & M University and Frederic Baltzer of the University of Paris, Sud. The objectives of the project are to determine: (1) how the interplay between mudbank migration and mudcape growth controls accretion and erosion on the Amapa-Guianas coast and (2) how recruitment, growth rates, and survival of coast mangrove swamps are dependent on these mechanisms. The researchers will conduct a joint field study in French Guiana and bring together information collected by these research groups in previous field studies. The US investigators bring to this collaboration expertise in sedimentology, geochronology and marine geophysics. This is complemented by French expertise in ecological, botanical and sedimentological studies of mangrove swamps. The project will advance understanding of the natural processes that control the evolution of a muddy coastal system. These systems make up a significant proportion of the world's coast zones and are critical habitats that are disappearing under human encroachment.

这个为期两年的奖项为美法合作研究自然提供支持， 亚马逊沉积物的积累沿着南美洲的圭亚那-阿马帕海岸。 这项合作涉及由德克萨斯州A M的Mead Allison领导的研究小组 大学和弗雷德里克巴尔茨的巴黎大学，南。 的目标 项目的主要目的是确定：（1）泥滩迁移与泥岬的相互作用 生长控制加积和侵蚀的阿马帕-圭亚那海岸和（2）如何 补充，增长率，和海岸红树林沼泽的生存依赖于这些 机制等 研究人员将在法属圭亚那进行联合实地研究， 这些研究小组在以往的实地研究中收集到的资料。 美国调查人员为这次合作带来了沉积学方面的专业知识， 地质年代学和海洋生物物理学。 法国在以下方面的专门知识对此予以补充： 红树林沼泽生态学、植物学和沉积学研究。 项目 将推进对控制泥质生物进化的自然过程的理解， 海岸系统 这些系统构成了世界海岸的重要部分 这些地区和重要的栖息地正在人类的侵蚀下消失。
