Developments in the understanding of processes in the P cycle: new concepts from the use of isotopic tracers

这项请求是为了支持一个研讨会，该研讨会将促进地球、海洋和农业科学家以及生物学家、湖泊学家、考古学家和气候科学家在磷(P)循环方面的国际科学合作。磷(P)是所有生物的必需营养；但是，尽管磷资源正在减少，在许多环境中，如热带，磷限制了农业生产，但过量的磷负荷会导致富营养化，降低水质和生态系统变化。研讨会将于2012年6月在瑞士蒙特维里察的Stefano Franscini中心举行，将由苏黎世瑞士联邦理工学院(ETH Zurich)共同资助。研讨会将由S.Bernasconi博士、E.Frossard博士和F.Tamburini博士(均来自苏黎世大学)与Adina Paytan博士(UCSC)合作组织。瑞士主办方将安排现场后勤，所有主办方在协调科学计划方面将分担同等责任。会议将侧重于：(A)目前对磷循环的理解和确定知识差距；(B)引进可填补这一差距的新方法和技术(重点是稳定同位素)；以及(C)促进国际合作，利用新工具促进我们对环境中磷的了解。参与者将包括来自大学和政府研究机构的研究人员、博士后和来自许多国家的学生。这项活动将汇集来自世界各地的大学教授、研究科学家、博士后研究员和研究生，包括美国、欧洲、中东和其他国家。讲习班的成果将导致对应用创新方法研究我们环境中的磷以及人类活动对磷周期的影响的新见解。这笔旅行补助金的资助对象是年轻的美国科学家，使他们能够在国际科学界建立重要联系，并为培训下一代环境科学家做出贡献。研讨会的结论和成果将在一份议事文件中广泛传播，并可能最终在一期特刊、国际会议的专门会议和相关门户网站上发表手稿。

This is a request to support a workshop that will promote international scientific collaboration on phosphorus (P) cycling for earth, ocean and agricultural scientist as well as biologists, limnologists, archeologists and climate scientists. Phosphorus (P) is an essential nutrient for all living organisms; but while P resources are dwindling and in many environments, such as the tropics, P limits agricultural production, excessive P loading can cause eutrophication, reduce water quality and ecosystem alteration.The workshop will be held in June of 2012 in the Centro Stefano Franscini (CSF), Monte Verità, Switzerland, and will be co-funded by Swiss Federal Institute of Technology in Zürich (ETH Zurich). The workshop will be organized by Drs. S. Bernasconi, E. Frossard, and F. Tamburini (all form ETH Zürich) in collaboration with Dr. Adina Paytan (UCSC). The Swiss organizers will arrange for on site logistics and all of the organizers will share equal responsibilities in coordinating the scientific program. The meeting will focus on: (a) the current understanding of the P cycle and defining knowledge gaps, (b) introduction of new methodologies and technologies (with focus on stable isotopes) that may fill the gaps, and (c) fostering international collaborations that will use new tools to advance our knowledge on P in our environment. Participants will include researchers from universities and government research institutes, post docs, and students from many countries. The activity will bring together a diverse community of university professors, research scientists, post doctoral fellows and graduate students from all around the world including the United States, Europe, the Middle East and additional countries. Outcomes from the workshop will lead to new insights regarding application of innovative methodologies to the study of P in our environment and the impact of human activity on the P cycle. Support under this travel grant is targeted to young U.S. scientists, enabling them to make important contacts in the international scientific community, and contributing to the training of the next generation of environmental scientists. Conclusions and outcomes from this workshop will be disseminated broadly in a proceedings document and likely culminated in publication of manuscripts in a special issue, dedicated sessions in international meetings and through relevant web portals.
