Structural and kinematic models of the Aegean based on HALO gravity and magnetic data

HALO地球科学用户组正在提出GEOHALO任务，以展示HALO在地球科学应用方面的创新能力。HALO对地球科学的主要优势是其远程能力，这意味着可以在偏远地区（南极洲、喜马拉雅、亚马逊）获得大量数据。在高海拔飞行的能力提供了连接地面和卫星（CHAMP， GRACE， GOCE）重力和磁数据的机会。第一个HALO地球科学任务将在爱琴海上空飞行，爱琴海是欧洲地震最活跃的地区。GEOHALO任务包括四个项目，涉及获取（包括新仪器）、处理和解释机载重力和磁数据以及使用全球卫星导航系统对大气进行遥感。6个800公里长的平行剖面将在2.5公里高空飞行，以绘制爱琴海的重力和磁异常。高空观测将沿着在15公里高度飞行的附加线进行。GEOHALO项目3的重点是为HALO准备磁力计，并将HALO重磁数据应用于爱琴海地区岩石圈结构和动力学的建模和解释。我们的目标是改进爱琴海重力和磁场的地图，以便更好地了解爱琴海岩石圈的结构和运动学。对这些性质的进一步了解有助于我们理解与希腊俯冲带和北安纳托利亚断层有关的地震和海啸危险。

The HALO Geoscience User Group is proposing the GEOHALO Mission to demonstrate the innovative capabilities of HALO for geoscience applications. The main advantage of HALO for the geosciences is its long-range capability, meaning that extensive data can be obtained in remote regions (Antarctica, Himalaya, Amazon). The ability to fly at high elevations provides the chance to link surface and satellite (CHAMP, GRACE, GOCE) gravity and magnetic data. The first HALO geoscience mission will be flown over the Aegean Sea, the most seismically active part of Europe. The GEOHALO Mission comprises four projects that deal with acquisition (including new instrumentation), processing and interpretation of airborne gravity and magnetic data and remote sensing of the atmosphere using Global Satellite Navigation Systems. Six 800-km long, parallel profiles will be flown at 2.5 km elevation in order to map Aegean gravity and magnetic anomalies. High-altitude observations will be made along an additional line flown at 15 km elevation. The focus of this proposal, GEOHALO Project 3, is the preparation of magnetometers for HALO and the application of the HALO gravity and magnetic data to modelling and interpreting lithospheric structure and dynamics in the Aegean region. We aim to improve maps of the Aegean gravity and magnetic fields in order to better understand Aegean lithospheric structure and kinematics. Improved knowledge of these properties helps our understanding of earthquake and tsunami hazard associated with the Hellenic subduction zone and the North-Anatolian fault.
