This award supports an aeromagnetic survey of part of Ross- Transect, Antarctica, in cooperation with the FRG Federal Institute for Geosciences and Resources (BGR). Two BGR ski- equipped Dornier 228 geophysical aircraft will be operated from McMurdo Station. Specific scientific objectives of the survey are: (1) The northwest part of the Ross Ice Shelf; to determine whether the Terror Rift in the Victoria Land Basin continues south of Ross Island and to establish the presence or absence of submarine and subglacial volcanos and subvolcanic intrusions associated with the late Cenozoic rifting; and (2) Ross Island, an active volcanic edifice; to locate areas of thin volcanic cover which could be used for scientific drilling sites on land.

该奖项支持与德国联邦地球科学与资源研究所 (BGR) 合作对南极洲罗斯断面部分地区进行航磁调查。 两架配备 BGR 滑雪设备的道尼尔 228 地球物理飞机将在麦克默多站运行。 此次调查的具体科学目标是：（1）罗斯冰架西北部；确定维多利亚陆盆地的恐怖裂谷是否继续延伸到罗斯岛以南，并确定是否存在与新生代晚期裂谷相关的海底和冰下火山以及火山下侵入； (2) 罗斯岛，一座活火山建筑；定位可用于陆地科学钻探场地的薄火山覆盖区域。
