Eustatic Sea Level Calibrated By Balanced Paleogeographic Maps of Europe

这项研究奖将帮助调查员利用关于陆上和近海地区的沉积物类型、厚度、年龄和孔隙度的现有资料以及全球沉积物质平衡方程，重建西欧和邻近的北大西洋陆架和盆地的平衡古地形图。这种将被侵蚀的沉积物装载回大陆，然后计算大陆地形，从而得出隆起和沉降率的技术，具有非凡的想象力和创新性。PI利用类似的数据库和物质平衡计算，在重建北美大陆及其邻近地区过去70年的古地形、古流域、古大地测量和过去的隆起和沉陷方面取得了极其成功的成就。这种平衡的古地理图将为西欧的海平面曲线提供校准，并将有助于确定每个水系和沉积盆地的陆源运动相对于海平面变化的意义。此外，这种建模技术将产生复杂的气候和海洋环流建模所需的那种地形信息。在第一年和第二年，PI在慕尼黑大学休假期间将收集必要的数据。随后将进行严格的计算机密集工作，以生成古地理地图。这项研究代表了一种确定古海平面升降的全新方法，这是目前许多研究的主题。海博士是一位非常有能力的科学家，在过去的十年里，他在各种学科的开创性研究中发挥了领导作用，毫无疑问，拟议中的研究将

This research award will help the investigator to reconstruct balanced paleographic maps of the Western Europe and the adjacent North Atlantic shelves and basins using the available information on the sediment types, their thicknesses, ages and porosities for the onshore and offshore areas and global sedimentary mass balance equations. This technique of loading the eroded sediments back on to the continent and then calculating the continental topography and thereby arriving at the uplift and subsidence rates is extraodinarily imaginative and innovative. The PI using a similar data base and mass balance calculations was extremely successful in reconstructing paleotopography, paleodrainage basins, paleobathymetry and past uplifts and subsidences of the North American continent and the adjoining areas for the last 70 MY. Such balanced paleogeographic maps will provide calibration for the sea level curve for the Western Europe and will help in determining the significance of epeirogenic movements vis-a-vis eustatic sea level changes in each of the drainage and depositional basins. Also this modeling technique will produce the kind of topographic information that is required for sophisticated climate and ocean circulation modeling. During the 1st and 2nd year, the PI while on his sabbatical in University of Munich will gather the necessary data. This will be followed by rigorous computer intensive work to generate paleographic maps. This study represents a wholly new approach in the determination of paleo sea level rises and falls, a subject of much investigation at the present time. Dr. Hay is an extremely capable scientist who for the last decade took leadership in pioneering research in a variety of subjects and there is no doubt that the proposed study will
