941583 Gorsline This Americas Program award will support the doctoral dissertation research of two students, M.C. Enrique Nava Sanchez, and M.C. Janette Murillo de Nava, under the direction of Dr. Donn Gorsline, University of Southern California, Los Angeles, on coastal studies in Baja California Sur, Mexico. The goal of the project is to obtain a comparative understanding of little known arid and semiarid coastal types. Emphasis will be in two areas: the fan-deltas of the Gulf of California coast of Baja California Sur and the semi-arid Magdalena Coastal Plain of the Central Pacific coast of Baja California. These tectonically active areas provide a unique opportunity to contrast broad coastal plain evolution with steep mountain fan-delta coasts under similar climatic conditions. Fan-delta deposits are very important potential stratigraphic hydrocarbon reservoirs. In the study area they serve as ground water reservoirs and as main habitation areas. An understanding of their geometry, architecture, physical properties and physiography is thus of considerable significance. Modern work on fan-deltas has been mainly done in glacial or humid areas and models for the deposits are based on outercrops in East Greenland and their occurrences in the North Sea. By diversifying the climatic and physiographic setting, this study will provide an important addition to the field of sedimentology and to ongoing studies in Arctic fjords and protected waters elsewhere. *** .

941583 Gorsline美洲项目奖将在洛杉矶南加州大学Donn Gorsline博士的指导下，支持两名学生M.C. Enrique Nava Sanchez和M.C. Janette Murillo de Nava的博士论文研究，研究内容是墨西哥下加利福尼亚州南部的沿海研究。该项目的目标是获得对鲜为人知的干旱和半干旱沿海类型的比较了解。重点将放在两个地区：下加利福尼亚州南部加利福尼亚湾沿岸的扇三角洲和下加利福尼亚州中部太平洋沿岸半干旱的马格达莱纳沿海平原。这些构造活动区提供了一个独特的机会，在类似的气候条件下，对比广阔的沿海平原和陡峭的山地扇三角洲海岸。扇三角洲沉积是非常重要的潜在地层油气藏。在研究区内，它们作为地下水库和主要居住区。因此，了解它们的几何、建筑、物理特性和地理特征是相当重要的。关于扇三角洲的现代研究主要是在冰川或潮湿地区进行的，沉积模型是基于东格陵兰岛的表层沉积物及其在北海的分布。通过多样化的气候和地理环境，这项研究将为沉积学领域和正在进行的北极峡湾和其他受保护水域的研究提供重要的补充。* * *。
