Fletcher.9908594The nature of coastal change occurring over the time frame of decades to millennia, a period that is highly relevant to human concerns, is poorly understood. For instance, scientists do not have even a rudimentary understanding of how interannual processes govern sediment sharing across the littoral energy fence. What is the repeatability (or variation) of states of stability or change on the inter-decadal scale? What are the temporal and spatial characteristics of physical processes that link the shoreline to the inner shelf on the century to millennial scale? Which of these nested time scales is responsible for the greatest amount of work in determining the fate of coastal sediments and the character of the shoreline system at any moment in time? An improved ability to effectively answer these questions, an others, will be critically valuable to the coastal planning community, permitting authorities, and resource managers. This proposal seeks participant support funding and logistical funding to defray the cost of holding a research conference and planning workshop of international scientists active in the broad field of coastal geology. The principal focus of the workshop is the Quaternary sedimentological history of sea-level changes and shoreline and inner shelf sedimentological processes and their past and future impact on society and human issues. The conference will convene November 9-12, 1999 on the campus of the University of Hawaii, Honolulu.

Fletcher.9908594 人们对几十年到几千年期间发生的海岸变化的性质知之甚少，这一时期与人类关注的问题高度相关。 例如，科学家们对年际过程如何控制沿海能量栅栏沉积物的共享甚至没有基本的了解。 年代际尺度上稳定或变化状态的重复性（或变化）是多少？ 在本世纪到千年尺度上，连接海岸线和内陆架的物理过程的时空特征是什么？ 在确定任意时刻沿海沉积物的命运和海岸线系统的特征时，这些嵌套时间尺度中的哪一个负责的工作量最大？ 提高有效回答这些问题和其他问题的能力对于沿海规划界、许可当局和资源管理者来说至关重要。该提案寻求参与者支持资金和后勤资金，以支付活跃在沿海地质学广泛领域的国际科学家举办研究会议和规划研讨会的费用。 研讨会的主要重点是海平面变化、海岸线和内陆架沉积过程的第四纪沉积学历史及其过去和未来对社会和人类问题的影响。 会议将于 1999 年 11 月 9 日至 12 日在檀香山夏威夷大学校园举行。
