US-France Planning Visit and Workshop: Modern Biogeochemical Cycling Processes in Mud Wave-Deltaic Deposits Along the Guianas Coast, Kourou, French Guiana

0334664Aller这个为期一年的奖项支持对法属圭亚那库鲁的计划访问和随后的研讨会，以探索美法合作研究亚马逊-圭亚那海岸泥波三角洲沉积的生物地球化学循环过程。红树林边缘的海岸线，如圭亚那群岛沿岸的海岸线，与沿海海洋循环和交换营养物质，并显著提高附近水域的肥力。由纽约州立大学(SUNY)石溪分校的Josephine Y.aller和法属圭亚那Kourou的National de la Recherche Science(CNRS)研究实验室的Francois Fromard和Alain Pave领导，美国和法国的研究人员将为在圭亚那一个典型的沿海泥石波系统中进行微生物生物地球化学和现代元素循环的研究奠定基础。它们将解决沉积运输过程、早期成岩反应、潮间带和潮下沉积物中的微生物群落以及红树林边缘、沿海水域和大气之间的物质交换等问题。NSF将资助一个来自纽约州立大学石溪分校、杜兰大学和路易斯安那大学的6人多学科团队前往法属圭亚那的旅行。他们将会见来自几所法国大学和位于库鲁的CNRS研究平台、库鲁的国家农业工程、水管理和森林学院以及卡宴发展研究所的科学家。这一讲习班将为推进对热带沿海边缘中心作用的研究奠定基础，热带沿海边缘目前在世界海洋的大陆材料投入中占主导地位。

0334664AllerThis one-year award supports a planning visit to Kourou, French Guiana and subsequent workshop to explore U.S.-France cooperative research on biogeochemical cycling processes in mud wave-deltaic deposits along the Amazon - Guianas coast. Mangrove-fringed coastlines, such as those along the Guianas, recycle and exchange nutrients with the coastal ocean and significantly increase the fertility of adjacent waters. Led by Josephine Y. Aller of the State University of New York (SUNY) at Stony Brook and Francois Fromard and Alain Pave of the Centre National de la Recherche Scientifique (CNRS) research laboratory in Kourou, French Guiana, the U.S. and French researchers will lay the groundwork for investigations in microbial biogeochemistry and modern elemental cycling in a typical coastal mud wave system along the Guianas. They will address issues of sedimentary transport processes, early digenetic reactions, the microbial community in the intertidal and sub tidal deposits, and the exchange of material between the mangrove fringe, coastal waters, and atmosphere. NSF will fund travel to French Guiana of a 6 person multidisciplinary team from SUNY Stony Brook, Tulane University, and University of Louisiana. They will meet with scientists from several French universities and from the CNRS research platform located in Kourou, the National College for Agricultural Engineering, Water Management and Forests in Kourou, and the Research Institute for Development in Cayenne. This workshop would set the stage for advancing research on the central role of tropical coastal margins, which presently dominate continental inputs of materials in the world oceans.
