The Non-Steady State of the Inner Shelf and Shoreline: Coastal Change on the Time Scale of Decades to Millennia in the Late Quaternary

在几十年到几千年的时间范围内发生的海岸变化的性质，与人类关切的问题高度相关，人们对此知之甚少。例如，科学家们甚至对年际过程如何管理沿海能源围栏内的沉积物共享没有基本的了解。年代际尺度上稳定或变化状态的重复性(或变化性)是多少？在世纪到千年的尺度上，将海岸线与内陆架联系起来的物理过程的时间和空间特征是什么？在任何时刻，在决定海岸沉积物的命运和海岸线系统的特征方面，这些嵌套的时间尺度中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，将对沿海规划界、许可当局和资源管理者具有至关重要的价值。该提案寻求参与者支助资金和后勤资金，以支付为活跃在广泛的沿海地质学领域的国际科学家举办一次研究会议和规划讲习班的费用。讲习班的主要重点是海平面变化的第四纪沉积学历史和海岸线和内陆架的沉积学过程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。

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.
