Ship-based Trackline Geophysical Data (MGD77) acquired along the Lau Back-arc Basin during the Maurice Ewing expedition EW9914 (1999)

This data set was acquired with a ship-based BellAerospace BGM-3 Gravimeter, Geometrics G-886 Magnetometer, and Atlas Hydrosweep DS Multibeam Sonar system during Maurice Ewing expedition EW9914 conducted in 1999 (Chief Scientist: Dr. Alistair Harding). These data files are of MGD77 format and include Singlebeam Bathymetry, Gravity Field, and Magnetic Field data and were processed after data collection. Data were acquired as part of the project(s): A MCS Survey of the Lau Spreading Center: A New Look into Crustal Accretion at Back Arc Spreading Centers, and funding was provided by NSF grant(s): OCE95-29870 and OCE95-30325.

本数据集通过船载贝尔航空BGM-3重力仪（BellAerospace BGM-3 Gravimeter）、Geometrics G-886磁力仪（Geometrics G-886 Magnetometer）以及Atlas Hydrosweep DS多波束声呐系统（Atlas Hydrosweep DS Multibeam Sonar system）采集完成，数据采集工作属于1999年开展的莫里斯·尤因（Maurice Ewing）航次EW9914，该航次首席科学家为阿利斯泰尔·哈丁博士（Dr. Alistair Harding）。本数据集文件采用MGD77格式，涵盖单波束测深（Singlebeam Bathymetry）、重力场（Gravity Field）与磁场（Magnetic Field）三类数据，且所有数据均在采集完成后进行了预处理。本次数据采集隶属于研究项目《劳扩张中心多道地震调查：弧后扩张中心地壳增生的新视角》（A MCS Survey of the Lau Spreading Center: A New Look into Crustal Accretion at Back Arc Spreading Centers），项目得到美国国家科学基金会（NSF）的资助，资助编号为OCE95-29870与OCE95-30325。
