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

沿海变化的性质发生在几十年到几千年的时间框架内，这一时期与人类的关注高度相关，但人们对其知之甚少。例如，科学家们甚至对年际过程如何控制沿海能量栅栏上的沉积物共享都没有基本的了解。在年代际尺度上，稳定或变化状态的可重复性（或变化性）是什么？在世纪到千年的尺度上，连接海岸线和内大陆架的物理过程的时间和空间特征是什么？在这些嵌套的时间尺度中，哪一个在决定沿海沉积物的命运和任何时刻海岸线系统的特征方面承担了最大的工作量？提高有效回答这些问题和其他问题的能力，对沿海规划界、许可当局和资源管理者来说将是至关重要的。这项建议寻求参与者支助资金和后勤资金，以支付举办研究会议和规划讲习班的费用，这些讲习班是由活跃在沿海地质学广泛领域的国际科学家参加的。研讨会的主要焦点是第四纪海平面变化的沉积史以及海岸线和内陆架沉积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日在檀香山的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.
