Funds support a paleomagnetic study of Holocene sediments from the northern North Atlantic, which will involve synthesis of existing data and radiocarbon dates. The study involves three objectives: (1) to use high sedimentation rate cores from the Iceland-Greenland area to refine and extend an ongoing Holocene geomagnetic reconstruction of the northern North Atlantic, (2) to use the reconstructed Holocene geomagnetic record as an accurate geomagnetic input to compare with paleomagnetic output from a series of well-dated cores, and (3) to develop an environmental magnetic synthesis of the region to further constrain sediment dynamics associated with glacial retreat and ocean circulation. Results will enhance understanding of the geodynamo and the relative effects of solar vs geomagnetic control on the cosmogenic ray load at the earth?s surface. The award will support a post-doctoral researcher, and will involved graduate and undergraduate students.

资金支持对北大西洋北部全新世沉积物的古地磁研究，该研究将包括对现有数据和放射性碳年代的综合。这项研究有三个目标：(1)利用冰岛-格陵兰地区的高沉积速率岩心对北大西洋北部的全新世地磁重建进行改进和扩展；(2)利用重建的全新世地磁记录作为精确的地磁输入，与一系列年代确定的岩心的古地磁输出进行比较；(3)建立该地区的环境磁综合，进一步约束与冰川退缩和海洋环流相关的沉积动力学。结果将加强对地球动力学和太阳与地磁控制对地球上宇宙射线负荷的相对影响的理解。年代的表面。该奖项将支持一名博士后研究员，并将涉及研究生和本科生。
