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.

本深拖磁法总场及异常数据集，由搭载于DeepTow-MISO型拖曳滑橇的SeaSPY型总场质子旋进磁力仪采集，采集工作于2011年Thompson航次TN272期间开展，作业海域为西太平洋，首席科学家为Masako Tominaga与Maurice Tivey。

本数据集经处理后的文件采用ASCII格式，附带列标题。其中磁力数据已完成校准，与经拖曳延迟校正计算得到的导航数据合并，并移除了国际地磁参考场（International Geomagnetic Reference Field, IGRF）的影响。

本数据集为两项研究项目的产出成果：《夏威夷侏罗纪地壳深潜自主水下航行器磁法与地震研究——侏罗纪磁异常的全球意义》，以及《夏威夷侏罗纪盆地高分辨率深潜自主水下航行器磁法调查》。本研究由美国国家科学基金会（National Science Foundation, NSF）的EAR10-29965、OCE10-29573及EAR12-33000项目资助。
