Holocene paleomagnetic record and observations on magnetic acquisition from North Atlantic sediments

资金支持对北大西洋北方全新世沉积物进行古地磁研究，这将涉及现有数据和放射性碳年代测定的综合。这项研究涉及三个目标：（1）使用冰岛-格陵兰地区的高沉积速率岩心来改进和扩展正在进行的北大西洋北方全新世地磁重建，（2）使用重建的全新世地磁记录作为准确的地磁输入，以与一系列年代较好的岩心的古地磁输出进行比较，以及（3）开发该地区的环境磁力合成，以进一步限制与冰川退缩和海洋环流相关的沉积动力学。研究结果将增进对地球发电机的理解，以及太阳与地磁控制对地球宇宙射线负荷的相对影响。s表面。该奖项将支持博士后研究人员，并将涉及研究生和本科生。

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.
