Deep-Tow magnetics total field and anomaly data (ASCII format), Jurassic Quiet Zone survey (TN272, 2011)

This deep-tow magnetics total field and anomaly data set was collected with a total field SeaSPY precession magnetometer attached to the DeepTow-MISO towed sled during the 2011 Thompson cruise TN272 to the western Pacific (chief scientists Masako Tominaga and Maurice Tivey). These processed data files are in ASCII format, with column headers. The magnetics values have been calibrated, merged with layback-computed navigation, and the IGRF has been removed.The data set was generated as part of the projects called A Deep-AUV Magnetic and Seismic Study of the Hawaiian Jurassic Crust - The Global Significance of Jurassic Magnetic Anomalies; and, A High-Resolution Deep-AUV Magnetic Survey of the Hawaiian Jurassic Basin. Funding was provided from NSF awards EAR10-29965, OCE10-29573 and EAR12-33000.

本深度拖曳磁力总场及异常数据集由SeaSPY总场磁力计采集而成，该磁力计连接于DeepTow-MISO拖曳滑撬，并于2011年Thompson巡航TN272任务中驶往西太平洋（首席科学家为Tominaga Masako和Tivey Maurice）。经处理的这些数据文件采用ASCII格式，并带有列标题。磁力值已进行校准，并与基于回放计算的导航数据合并，同时消除了国际地磁参考场（IGRF）。该数据集的生成是作为以下项目的成果：一项关于夏威夷 Jurassic 地壳的深海无人潜水器磁性和地震研究——Jurassic 磁性异常的全球意义；以及夏威夷 Jurassic 盆地的高分辨率深海无人潜水器磁力调查。项目资金由NSF资助，资助编号分别为EAR10-29965、OCE10-29573和EAR12-33000。
