Ship-based Trackline Geophysical Data (MGD77) acquired during the Maurice Ewing expedition EW9505 (1995)

This data set was acquired with a ship-based Atlas Hydrosweep DS Multibeam Sonar system and BellAerospace BGM-3 Gravimeter during Maurice Ewing expedition EW9505 conducted in 1995 (Chief Scientist: Dr. Andrew Fisher). These data files are of MGD77 format and include Gravity Field and Singlebeam Bathymetry data and were processed after data collection. Data were acquired as part of the project(s): The Fine-Scale Hydrogeology & Geochemistry of the Areas of Active Venting in Middle Valley, a Sedimented Rift of the Northern Juan De Fuca Ridge, and funding was provided by NSF grant(s): OCE94-15762, OCE94-15869, OCE94-17011, and OCE95-96253.

本数据集由船载Atlas Hydrosweep DS型多波束声呐系统（Atlas Hydrosweep DS Multibeam Sonar）与BellAerospace BGM-3重力仪（BellAerospace BGM-3 Gravimeter）采集获取，采集工作于1995年开展的Maurice Ewing航次EW9505期间执行，本次航次首席科学家为Andrew Fisher博士。本数据集采用MGD77格式存储，包含重力场数据与单波束测深数据，且已在数据采集完成后完成后期处理。本次数据采集隶属于研究项目《胡安·德·富卡洋脊北部沉积裂谷中谷活跃喷口区精细尺度水文地质与地球化学研究》，研究经费由美国国家科学基金会（NSF）资助，资助编号分别为OCE94-15762、OCE94-15869、OCE94-17011及OCE95-96253。
