Atlas of Glacimarine Features

该奖项支持编辑和准备工作，以开发冰川特征地图集。晚新生代的冰川作用直接影响了地球一半以上大陆架的沉积。冰继续对格陵兰岛周围、面向北冰洋的冰架以及南极洲周围的沉积产生主要影响。在其他地方，冰川海洋沉积在北美、欧洲北部、欧洲西北部和俄罗斯的冰架上具有特别重要的意义，这些冰架受到晚新生代冰川的强烈影响，尽管现在冰只是一个次要因素。这些冰架的特征包括真正的冰川海洋特征，即在靠近冰或受冰强烈影响的海洋环境中形成的冰架，以及由浮冰漂流造成的裂缝。还发现，由于在更新世海平面下降期间大面积的冰架暴露，陆地冰川和冰缘特征，如河流冲蚀谷和伴生沉积物、隧道谷、鼓林田、沉积田，随后被海洋影响淹没和改造。更好地了解当今的冰川海洋环境将加强对过去环境和这些解释所暗示的可能的全球气候变化的地层记录的解释，而从直接的实际角度来看，随着对能源和矿产资源的寻找扩展到高纬度和淹没地区，认识和理解冰架的特征将变得越来越重要。计划中的冰川海洋地图集将为专业人员、教师和学生提供参考，展示冰川-海洋环境中海底和海底特征的典型例子，因为这些特征出现在地震记录中（单通道和多通道地震反射，高分辨率，侧面扫描）。该地图集的可能用户将包括在大学、研究机构和政府机构工作的四元科学家、海洋地质学家、地球物理学家、岩土工程工程师和测量员，以及在近海工业（石油和硬矿物勘探和生产、土木工程、废物处理、环境问题等）工作的人。该地图集将在一个国际编辑委员会的指导下，根据科学界成员提交的稿件汇编而成。计划于1996年底出版。

Davies OPP 9526459 Abstract This award supports editing and preparation work to develop an Atlas of Glacimarine Features. Late Cenozoic glaciation directly affected sedimentation on more than half the Earth's continental shelves. Ice continues to be a dominant influence on sedimentation around Greenland and on the shelves facing the Arctic ocean as well as around Antarctica. Elsewhere, glacimarine sedimentation is of particular significance on the shelves of North America, north of, northwest Europe and Russia, which were strongly influenced by the Late Cenozoic Glaciation, though now ice is a minor factor. The features of these shelves include true glacimarine features, i.e. those formed in a marine environment in proximity to, or strongly under the influence of, ice, and diamictons resulting from ice rafting. Also found, since large areas of the shelves were exposed during the Pleistocene lowering of sea level, are terrestrial glacial and periglacial features, e.g. fluvial outwash valleys and associated deposits, tunnel valleys, drumlin fields, lodgement till, which have subsequently been submerged and modified by marine influences. Better understanding of present-day glacimarine environments will enhance interpretation of the stratigraphic record in terms of past environments and the possible global climate changes implied by these interpretations, while from an immediate practical standpoint, recognizing and understanding the features of glaciated shelves will become increasingly significant as the search for energy and mineral resources extends to higher latitudes and into submerged regions. The planned Atlas of Glacimarine Features will provide a reference for professionals, teachers and students showing typical examples of sea floor and sub sea floor features seen in glacio-marine environments, as these appear in seismic records (single and multi-channel seismic reflection, high resolution, side scan). Likely users of the atlas will include Qua ternary scientists, marine geologists, geophysicists, geotechnical engineers, and surveyors working in universities, research institutions and government agencies, as well as those in industries with offshore interests (petroleum and hard mineral exploration and production, civil engineering, waste disposal, environmental concerns, etc.). The atlas will be assembled under the guidance of an international editorial committee from contributions submitted by members of the scientific community. Publication is planned for late 1996.
